Those later Vauxhall engines used to show 'mayo' if they've been doing short journeys or little use. Maybe worth trying an engine flush then new oil & filter. Also sounds like the chain tensioner may be starting to go Bargain for £150 though 👌
You need to pressure test it, it's the best way to test a head gasket. If the gaskets gone between two cylinders and not near the water jacket exhaust won't make it's way into the expansion bottle, so the gas test won't show yellow
Hi mate, top tip I've rebuilt a few of these engines, as soon as you can get the sump pan off and check the oil pick up tube, they tend to clog up with debris and the top end gets starved of oil and knackers the head assembly. They're not bad engines really and they're pretty tough, if looked after.
We see a lot of these in our workshop and I have to say they’re poor engines tbh, rattly, underpowered and prone to a host of issues.. timing chains, hydraulic lifters, snapping camshafts, head gaskets, cracked blocks, top end rebuilds. Even with proper servicing.
Thank you somebody who knows they are a pretty good engine to be honest but nobody looks after them at all 90% of the problems are down to lack of maintenance at correct intervals but they are underpowered
Your mad scientist head tester isn't worth the plastic it's made from. Get a decent one with a bulb on the end so you can squeeze it and get the air/gasses through the fluid and that will be more accurate. Also check the dipstick to see if you can see water on the stick also check with the engine running the dip stick tube and filler cap for any blow by. The cams looked good as if their was water in the engine it normally gums up pretty good. And see if you can see any oil in the coolent drain decent emount leave it to sit for a few hours and it will separate. Nice Easy engines to work on you'll have no trouble at all going a timing chain and head gasket on the drive at home and just get the head skimmed if required so don't worry. Looking forward to more content and happy new year pal 👍
Ive got one of these Astras as a daily, with the exact same engine, woeful engines tbh, rattly, underpowered. Ignore the mayo in the cap its very common in these with short journeys or if they’ve been sat for a while. That rattling could be the timing chain which is soo common on these engines, about £400-£600 at a garage or about £60 for the kit if you do it yourself. Great video btw!
I’d personally try my luck with a good service, fresh oil, fresh coolant and flush, fresh plugs and coil packs she’s definitely misfiring, take it from there. Monitor for oil/coolant mix. Probably worth running a compression test across cylinders too 👍🏼
Everything you said. Its definitely misfire and i believe its pretty common on those for coil pack to go tits up. So much so AA patrols carry them coils on board as stock.
Had the same problem with my corsa d ,had the timing chain replaced with new gasket ,guides and sprockets ,my trouble was someone reused the timing chain gasket and stuck it back on with silicone, ran alot quiter after.
Had quite abit on my corsa's cap when i got it. Changed the rocker cover gasket and you could see it all in one corner where the old gasket had failed. That was a year ago and never came back.
I think the reason the corsa videos do well is because it’s a cheaper car we can all relate to makes it more enjoyable if you ask me. Looking forward to this project bro 👊 🔥
Defo worth getting the chain looked at, from memory these motors run on timing chains so can become very noisey! Get a full service on it, 02 sensor, an engine bay clean see if that mayo comes back!
Exactly the same issue on my Son's old Corsa, quickly diagnosed with a new timing chain kit. Throw on a new rocker cover gasket too after cleaning out the breather pipes.
Personally if it’s not over heating try a set off plugs and that may stop the misfire I had a 328i e36 with rlly bad milk on the oil cap but wasn’t headgasket it was just condensation
My guess is it’s running lean because of the o2 sensor. That sounds like lean pop on the engine. I’d also drop the oil. Easy way to tell if it’s got coolant in it. Same with the coolant. Just drop it and see if it’s mixed.
Renault Twingo's are notorious for "Mayo cap". They basically have it unless it's hot outside(ambient temp). Short journey, long journey, you name it. I always thought like you it was either headgasket or short journeys, simply not the case!
Pressure test all the cylinders it is possible to have a blown head gasket and only have coolant leaking into the oil, I had a similar issue on my 1991 Suzuki gsxr400 except the exhaust gases was getting into the coolant but not the oil and that was down to a blown head gasket but luckily a sniff test gave me the answers but for you, you’ll definitely need to do a leak down test on the cylinders if that comes back fine then you know your head gasket is fine. Hope this helps
I’ve had a few of these with supposed headgasket issues. I changed the thermostats, flushed the coolant a few times and serviced them. Put about 100/150 miles on them after and they never overheated.
It needs a major service fresh coolant spark plugs coil packs but I’m sure these engines have one long single coilpack also do the air filter clean the mass air flow sensor also replace the o2 sensor as well and take it for a long drive
ive had several of these astras very common for the oil pressure switch to leak so check that cheap and easy that one its located at front of engine left hand side
My oil cap always looked like that when I had one, timing chain love making a noise before I change it, the oil pressure sensor at the front on for engine would let oil out which run down the front.
Ive got the Sri and when mine sounded like that it was the coil pack there known to always go on these plus change the plugs at same time, the cap just looks like condensation due to not being run for a while
Not sure if these engines have one but if theres an oil cooler that coolant passes through that could also be the reason for "mayo" on the oil cap but as previous comments have said a pressure test will show alot easier also a compression test would show a failing headgasket as cylinder pressure would be less if the gasket has failed
I have a 2011 astra van h . Some people slag them off but you know what had it 12 years since new and uts been so reliable.. regular maintenance is all thay need i do a service eavery 6 months.. it is currently in need of a Alternator but it still got me 200 miles to wales and back with a Alternator that barely charges.. look after them properly and thay keep going
I've been following you since the beginning and have enjoyed all your videos, but this project is going to be one of my favorites because I have an Astra H with the same engine. I also had a burnt cylinder head gasket because the accessory belt broke while driving (you can ask the previous owner if his accessory belt broke while driving), check if the antifreeze is leaking or if the antifreeze is bubbling in the expansion tank if there are air bubbles in the expansion tank, check if it loses antifreeze from one day to the next, check the cap on the expansion tank if it is defective (when it is defective the tests fail and let you think that it would not be the head gasket), you can try with another cap that you know is not defective and if the engine goes crazy with the new cap then the cylinder head gasket is burnt. For you, it could be something else, maybe the water pump. The infernal noise from the engine may be due to the distribution, it did the same to me and I also changed it at the same number of kilometers.
You've touched on a good point mate, I've repaired a few of these that have cooked themselves due to the belt being thrown off/shredded and with no temp gauge the driver has no idea it's cooking itself the only clue is the battery light, as alternator isn't turning.
@@jameznmThank you, mate! You're right, you don't realize if the cylinder head gasket will burn because you don't see the temperature of the water in the engine. In my case, the accessory belt broke while I was driving on a national road and I didn't realize it in time because I was listening to the music a bit loud, I realized it when I noticed that the power steering stopped working, then I saw the battery light and after that the smoke also appeared. Since then I listen to music at a normal volume, enter the secret menu and check the temperature and check as often as I can. 😂 Most importantly, I check the accessory belt and change it on time!
I had exactly the same issue on same engine. Same symptoms as yours (engine light, rough running, mayo under cap and same codes for 02 sensors) it only cost 450 for the car so bought cheap 02 sensors to try and get me through another few months of motoring. Both sensors were a nightmare to remove!! Managed to change them and made no difference at all. In the end I suspect it was head gasket. I ran the car until it went pop and got rid!
Get the rocker cover of and heck the rockers mines sounded like that turned out the tappats broke by the rocker which then broke the rocker leading to the head gasket failure as one bank stopped working, also check the steering rack the thr pinion goes in to the rack the housing around it breaks, just seen the steering rack on the one scanner
I cant comment on the Head Gasket but it needs testing correctly, if deemed the gasket is good then start with your 02 sensor before the cat, reset it and run it to relearn the values. Service the thing, oil/filter - plugs, flush the coolant, change the thermostat, check there is no coolant leaking from the EGR side which to be honest with these cars just take it off and clean it and refit with new gasket. Rocker cover gasket is easy and cheap, whilst the rocker cover is off clean the cover and check the breather piper holes are not all gunked up and the associated hoses top right of the rocker cover. Also check the oil pressure switch is not leaking, as another common one. I have a fixer upper run round, same as this and I have done all the above, and the coil pack , several thousand miles later, I have now have the thing running very rich, with the EML on and fault code indicating a fuel trim issue, I am going to test the MAF sensor tomorrow, as this is another common thing to go on these. Its a good run around when it works, mine is also very tap tap tappy on idle and it sounds like there is a rattle on turn over which I believe is oil starvation. I am eager to see what you do with this, if the head is fine then hopefully that sensor will sort your running problem.
Them testers only work if the head gasket has blown in the correct place aka cylinder to coolant. But head gasket can blow coolant to oil ways dumping coolant in the oil
No "mayo" on dipstick i say you be fine timing chain might be issue they usually good for 130k on a good serviced engine. People seem neglect oil changes on chained engines but think the crap in the oil gets between the links in a chain and make it wear which makes in stretch.
I had an astra with head gasket failure exact same engine i still have an astra i have the 1.7 cdti i live very local to burton be happy to give you a hand if you want sounds very noisy tho with that rattle may be worth replacing timing chain check dipstick if the dipstick is milky then head gasket has deffo failed, also the milk in the oil cap is common on these engines most likely condensation in the rocker cover change spark plugs might help and also coil pack in terms of a misfire also with mine i could smell petrol in the coolant bottle give it a smell to see if you can but most likely i reckon the head gasket is good maybe a mega major service will bring it back to good health
If you replace the o2 sensor, take the battery off first mate. I diagnosed a car for a customer it was bank 1 02 sensor, customer said they'd replace that themselves, next day i got a call to say theyd replaced it and it started overfuelling badly, stalling, and all the lights on the dash came on. Turns out they fried the ecu somehow.
You might just need a new timing chain! I changed my timing chain on my corsa on my driveway a few years back, took me a couple days but saved a fortune and would make great content! Also the mayo on the cap was the same with mine and it was just condensation in the end! After a new chain you couldn’t even hear the engine on! Good luck with it, look forward to the videos!
I've had many vauxhalls the cream on the oil cape could be condensation like you said...I'd personally flush the oil water ect go from there...on the video it sounds like it has a miss but a chain driven car sounds the same (if it's a chain) Would be worth a full service after you know 1000% the heads not gone Good luck with it mate nice to see someone else working on vauxhalls and not bloody 30-40 grand cars 😂
I did have feeling it might have been an astra, based off the driver seats when you sitting inside the car, my friends got an Astra H SXI and they're lovely cars to drive, not the most rapid thing but handles very well actually 🙂
could be the timing case gasket where the water comes from the engine it passes through the timing case to get to the water pump the gasket leaks and water gets into the timing case and in the oil system. Just done my sons corsa i thought it was head gasket to but it was the timing case gasket. . .
Change the oil pressure sensor/switch cheap as chips. Take that bigger breather pipe off the rocker cover and clean the inside. To reset key put in ignition, turn to one position and press lock and unlock button on key fob
Start the car feel the radiator hoses see if they pressurize- also sure these engines have condensation in the top of the engine if they are used in short journeys that can give mayo
Oil leak dripping on the manifold is the laminate gasket its an o ring and just deteriorated over time, misfire could be the coil pack, rattle on start up is probably VVT pulleys as had the same on mine, easy job to do and if you're doing the gasket then all is doable during that job piece of piss to do let me know if you need any advice
The mayo on the cap is just condensation buildup thats mixed with the oil. A engine flush and new oil will sort that. Try getting car upto temp and giving engine a rev and see if it smokes as it could be piston rings or valve stem seals
I’ve got an Astra and most likely it’s the head gasket. Mine was exactly like that, hardly had any tell tail signs I did everything else but at the end it was the Head Gasket. Best thing to do is pressure test it first though…
I’m quite familiar with these engines, it’s all normal after that mileage including the rattles and leak from rocker gasket, if head has blown it usually spews pressure out of expansion tank With cap closed , often a heavy white smoke from exhaust, the mayo is probably condensation, wipe it off and get hot and see if it clears a bit, also sounds like it’s probably overdue its oil service, Vauxhall say yearly my advice on this engine every 6 months for anyone that plans to keep the car, the temperature can top best side of 100c before cooling fan kicks in, that can be a shock when you first see it. Despite quirks of Astra H they’re still a good drivers car and fairly reliable.
An 11 plate mk5 vauxhall Astra, one of the very last before the mk6 changeover at 60 plate. The Astra van derived from the mk5 estate lasted until 2013 63 plate. It would be nice to save this Astra, plenty parts available from scrapyards etc. Vauxhall reinstated the analogue temperature gauge in the mk6 and mk7.
Good video keep up the good work you can see it's a fairly new 02 sensor don't get a cheap 02 sensor as all vauxhalls hate cheap ones will need a bosh one or dealer one. This is best advice I can give you.
I've had a 59 reg Astra just like yours and same engine. Mayo on the oil cap, always was condensation due to short runs in the winter. During summer was fine. And I've had exactly the same problem with the O2 sensor or lambda. But in my case was both of them. And it was running shitty like yours. Change both O2 sensors or get them from scrapyard and you'll be having a cheap car running.
That’s just condensation under the oil cap. Misfire will be o2 sensor and engine light will come on if you drive it I think. May actually be a really cheap fix 🤞🏽
Is the oil pressure sensor sound ? I had a leak on mine was dripping onto the engine and causing the oil burning smell . Eventually gave up completely and pissed oil all over .
Alot of short trips can cause condensation under the oil cap causing the mayonnaise because the car hasnt been ran long enough for the oil to warm up remember coolant will always warm quicker then oil, so just because water might be upto temp doesnt mean the oil would be, also im sure these vauxhall engines have problems with pcv pipes and the pcv valve which could also be causing the mayonnaise under the oil cap
Another good video jeese. Check the oil cooler they have a habit of letting oil In to the water my 1.8 Sri astra had the sane issues you have and was the oilcooler. Good luck see ypuin the next video 👌🏻
Awesome bro did say an Astra .. looking forward to future content on this.. them plugs look like burning to much oil .. think head gasket as definitely gone bro.. another reason sounds rattley is cam chain they rattle bad on them astra,s . But don’t give up on the old girl . 👍🏻👌👊🏻
I’ve got the 1.6 elite model yours sounds like mine with oil situation it’s where oil filter housing meets the engine block it’s self the gaskets are shit I dno about the 1.4 but mine 1.6/1.8 models it’s common it’s the oil cooler
It’s the oil cooler mixing coolant with oil and that’s probably where the oil leak is dripping down onto your down pipe .. it’s part of the oil filter housing
I think when you revved I thought I could there the tape heads and the chain sounded really loose Because I thought on my corsa the chain was gone but everything time I would rev it I could her the tape head and the Astra sound the exact same as my corsa and for the miss fire it could be down to the timing like it could jumped timing so that’s why it sound really rough?
Mate, the engine sounded like A box of nails in a washing machine on start up, common for the timing chains to stretch on these engines, I’d say that is why previous owner hasn’t got it sorted, if timing is out this would also cause a misfire, I’d ignore the oil cap mayo, most likely condensation or indeed the Pcv valve which is built into the cam cover 👍
Looks like the timing chain cover gasket has failed where the water pump bolts through, very common on the Vauxhall 1.2/1.4 engines, had this myself as well as a noisy timing chain so change that at the same time 🔧👍
The noise could be coming from the timing belt area and the tensioners I doubt the mayo under the cap is anything more than condensation if it's been sitting Also use a OEM O2 sensor the aftermarket ones are rubbish A good service and those things and it should be fine I rate the 1.8 vauxhall engine good strong engines if you keep on top of them
we have a 2 year old vaux vivaro van at work.... exp tank has gone all yellow.. bubbles in it... and salad cream on the exp cap 50k miles used every day.. runs fine... but they shi..e anyway.. how would we know.. my mums 12 old corsa is same... go figure.. N x
Id just change the lambda sensor and see what its like after. I dont think it will be head gasket tbh, with it being sat fir ages id say its just condensation build up on the cap

You paid Scrap value for it Jesse. Because it is Scrap.
When you doing another video Jesse been waiting
When are you doing another video really looking forward to it ???
Those later Vauxhall engines used to show 'mayo' if they've been doing short journeys or little use. Maybe worth trying an engine flush then new oil & filter. Also sounds like the chain tensioner may be starting to go
Bargain for £150 though 👌
You need to pressure test it, it's the best way to test a head gasket. If the gaskets gone between two cylinders and not near the water jacket exhaust won't make it's way into the expansion bottle, so the gas test won't show yellow
That's what I was going to say
Defo check comp, if head gaskets gone at least one cylinder will be low
Also sounds like an exhaust manifold leak somewhere too... 👂

Check if there is Mayo in the dip stick and check the breather pipes which do clog up with Mayo too.

I 100% back this as a starting point.
Everything you said. Its definitely misfire and i believe its pretty common on those for coil pack to go tits up. So much so AA patrols carry them coils on board as stock.
First instinct with a rough-sounding Vauxhall should always be new spark plugs and coil pack. Vauxhall coil packs are notorious.
Had the same problem with my corsa d ,had the timing chain replaced with new gasket ,guides and sprockets ,my trouble was someone reused the timing chain gasket and stuck it back on with silicone, ran alot quiter after.
Well l would change all of the spark plugs with brand new ones and may be empty the thermostat and enter fresh violent into the coolenr
Had quite abit on my corsa's cap when i got it. Changed the rocker cover gasket and you could see it all in one corner where the old gasket had failed. That was a year ago and never came back.
I think the reason the corsa videos do well is because it’s a cheaper car we can all relate to makes it more enjoyable if you ask me.
Looking forward to this project bro 👊 🔥
I agree! I owned a 1.2 and now upgraded to the vxr burg edition, cheap Vauxhalls have my heart and seeing them being fixed is just so fun!
Defo worth getting the chain looked at, from memory these motors run on timing chains so can become very noisey! Get a full service on it, 02 sensor, an engine bay clean see if that mayo comes back!
Pressure test it got a kitif you.need Jess and did you.give it revs when seeing if the liquid changed as might only leak under pressure
That mayo will b from your rocker cover gasket, quite common on these astras
Exactly the same issue on my Son's old Corsa, quickly diagnosed with a new timing chain kit. Throw on a new rocker cover gasket too after cleaning out the breather pipes.

When u do the head gasket test block off the breather hole as the gas will escape from it I had the same problem with a corsa

check the dipstick for the mayo, do a oil and filter change youl soon see mixed oil and coolant in the bottom of the pan when you do the oil change.

I've had many vauxhalls the cream on the oil cape could be condensation like you said...I'd personally flush the oil water ect go from there...on the video it sounds like it has a miss but a chain driven car sounds the same (if it's a chain)
Would be worth a full service after you know 1000% the heads not gone
Good luck with it mate nice to see someone else working on vauxhalls and not bloody 30-40 grand cars 😂
I did have feeling it might have been an astra, based off the driver seats when you sitting inside the car, my friends got an Astra H SXI and they're lovely cars to drive, not the most rapid thing but handles very well actually 🙂
I had an Astra diesel MK5, was good to drive tbf
could be the timing case gasket where the water comes from the engine it passes through the timing case to get to the water pump
the gasket leaks and water gets into the timing case and in the oil system. Just done my sons corsa i thought it was head gasket
to but it was the timing case gasket.

Change the oil pressure sensor/switch cheap as chips. Take that bigger breather pipe off the rocker cover and clean the inside. To reset key put in ignition, turn to one position and press lock and unlock button on key fob
Start the car feel the radiator hoses see if they pressurize- also sure these engines have condensation in the top of the engine if they are used in short journeys that can give mayo
Oil leak dripping on the manifold is the laminate gasket its an o ring and just deteriorated over time, misfire could be the coil pack, rattle on start up is probably VVT pulleys as had the same on mine, easy job to do and if you're doing the gasket then all is doable during that job piece of piss to do let me know if you need any advice
The mayo on the cap is just condensation buildup thats mixed with the oil. A engine flush and new oil will sort that. Try getting car upto temp and giving engine a rev and see if it smokes as it could be piston rings or valve stem seals
And the tapping noise is the vvt valves try removing the filters on them giving it a better oil feed
The diesel sound will the the cam pullyes worn on the vvt
so ur the person nicking all the cars. im here trying to get my first cat
I’ve got an Astra and most likely it’s the head gasket. Mine was exactly like that, hardly had any tell tail signs I did everything else but at the end it was the Head Gasket. Best thing to do is pressure test it first though…
Definitely get it pressure tested, any details on your code scanner tablet? Great video as always though
I’m quite familiar with these engines, it’s all normal after that mileage including the rattles and leak from rocker gasket, if head has blown it usually spews pressure out of expansion tank With cap closed , often a heavy white smoke from exhaust, the mayo is probably condensation, wipe it off and get hot and see if it clears a bit, also sounds like it’s probably overdue its oil service, Vauxhall say yearly my advice on this engine every 6 months for anyone that plans to keep the car, the temperature can top best side of 100c before cooling fan kicks in, that can be a shock when you first see it. Despite quirks of Astra H they’re still a good drivers car and fairly reliable.
An 11 plate mk5 vauxhall Astra, one of the very last before the mk6 changeover at 60 plate. The Astra van derived from the mk5 estate lasted until 2013 63 plate. It would be nice to save this Astra, plenty parts available from scrapyards etc. Vauxhall reinstated the analogue temperature gauge in the mk6 and mk7.
Means nowt lad just means that the 11 plated mk5s where not sold and sat a few months before registered mk 6 came out on a 59 plate
Good video keep up the good work you can see it's a fairly new 02 sensor don't get a cheap 02 sensor as all vauxhalls hate cheap ones will need a bosh one or dealer one. This is best advice I can give you.
I've had a 59 reg Astra just like yours and same engine. Mayo on the oil cap, always was condensation due to short runs in the winter. During summer was fine.
And I've had exactly the same problem with the O2 sensor or lambda. But in my case was both of them. And it was running shitty like yours. Change both O2 sensors or get them from scrapyard and you'll be having a cheap car running.
YES ! Can't wait for this content. I've has 2 Astra s in the past. Loved working on them, can't wait to see what your gonna do.
Sometimes the liquid colour doesn’t change even with a blown head gasket
That’s just condensation under the oil cap. Misfire will be o2 sensor and engine light will come on if you drive it I think. May actually be a really cheap fix 🤞🏽
Coil packs are common as muck on these engines
I would change the both engine and rocker cover gasket..
Having mixed signs has confused me as well so I would change both..
I would give it a good service and o2 sensor and would change the egr valve and cooler there are so common to go wrong plus a coolant flush
Ahhh explains why I never noticed what was on the drive before the Corsa it's a astra to many of them round here 😂
Ah man now I miss my 07 Astra SRi 1.9CDTi. Keep up the great work my guy.
What battery booster did you use Thanks
Is the oil pressure sensor sound ? I had a leak on mine was dripping onto the engine and causing the oil burning smell . Eventually gave up completely and pissed oil all over .
another nice old’ish’ vauxhall on the channel 👌🏻 unfortunately it isn’t an SRI though, the SRI astra was a 1.8 with a ‘sport’ button above the radio
Alot of short trips can cause condensation under the oil cap causing the mayonnaise because the car hasnt been ran long enough for the oil to warm up remember coolant will always warm quicker then oil, so just because water might be upto temp doesnt mean the oil would be, also im sure these vauxhall engines have problems with pcv pipes and the pcv valve which could also be causing the mayonnaise under the oil cap
Z20leh or z20let it, cheap and tuneable and would be a great series!
You csn get the glass for mirror from Halfords 7pound
It will show signs of head gasket if it’s not been used in a long time.and the battery toast
It’s rocker cover gasket
Nice easy project
With the mayo clean it of and you have get car running right hammer it on long journey that clear the moyo hopefully
Thinking about getting vectra Sri petrol good engines I believe what do you think
Yes what an amazing idea 💡 I love Astra’s can’t wait for the new videos of you doing the Astra up
Another good video jeese. Check the oil cooler they have a habit of letting oil In to the water my 1.8 Sri astra had the sane issues you have and was the oilcooler. Good luck see ypuin the next video 👌🏻
Awesome bro did say an Astra .. looking forward to future content on this.. them plugs look like burning to much oil .. think head gasket as definitely gone bro.. another reason sounds rattley is cam chain they rattle bad on them astra,s . But don’t give up on the old girl . 👍🏻👌👊🏻
I’ve got the 1.6 elite model yours sounds like mine with oil situation it’s where oil filter housing meets the engine block it’s self the gaskets are shit I dno about the 1.4 but mine 1.6/1.8 models it’s common it’s the oil cooler
the residue on the oil cap is quite normal on vauxhall engines they always get condensation
It’s the oil cooler mixing coolant with oil and that’s probably where the oil leak is dripping down onto your down pipe .. it’s part of the oil filter housing
where and how do you get cars this cheap? Am looking for projects too lol
Maby you can get a aftermarket clock for the temp gage I shore Thay sell them
Change rocker cover and the gasket and check the breather pipes for sludge
Jesse do these engines have an oil cooler fitted?
Check the oil cooler behind manifold.. seals go
Pressure test best way also put that liquid near exhaust to test the chemical reaction, those cheap kits usually pointless
I think when you revved I thought I could there the tape heads and the chain sounded really loose
Because I thought on my corsa the chain was gone but everything time I would rev it I could her the tape head and the Astra sound the exact same as my corsa and for the miss fire it could be down to the timing like it could jumped timing so that’s why it sound really rough?
That timing chain is fooked 14:49 /stretched J. Needs timing chain kit and timing chain chest cover gasket at a minimum.
Could it possibly be water pump related I know that often causes the mayo happened on my corsa just a thought
Mate, the engine sounded like
A box of nails in a washing machine on start up, common for the timing chains to stretch on these engines, I’d say that is why previous owner hasn’t got it sorted, if timing is out this would also cause a misfire, I’d ignore the oil cap mayo, most likely condensation or indeed the Pcv valve which is built into the cam cover 👍
Compression test the cylinders, coolant pressure test also. Quite normal that under the oil cap.
Fair play to you mate for pushing this to the max now! Came along way from back in the day 💯💯💯
Looks like the timing chain cover gasket has failed where the water pump bolts through, very common on the Vauxhall 1.2/1.4 engines, had this myself as well as a noisy timing chain so change that at the same time 🔧👍
The noise could be coming from the timing belt area and the tensioners
I doubt the mayo under the cap is anything more than condensation if it's been sitting
Also use a OEM O2 sensor the aftermarket ones are rubbish
A good service and those things and it should be fine
I rate the 1.8 vauxhall engine good strong engines if you keep on top of them
Get O2 sensor done,rocker cover gasket,and full service,and prob pump and belts
we have a 2 year old vaux vivaro van at work....
exp tank has gone all yellow..
bubbles in it...
and salad cream on the exp cap
50k miles used every day..
runs fine... but they shi..e anyway.. how would we know..
my mums 12 old corsa is same...
go figure..
N x
My past experience with astra is the white stuff doesn't mean head gasket them engine top half runs hot and the bottom cold
Coil pack, plugs, Timing chain and a downstream o2 sensor
Check the head bolts are tighten down and not loose
Id just change the lambda sensor and see what its like after. I dont think it will be head gasket tbh, with it being sat fir ages id say its just condensation build up on the cap
