Thanks mate👍
No sweat. Glad you found it helpful✅
Another fine kettle of fish. For what it's worth, I brought home a junkyard engine. Installed it prepped it to run. Starter turned about half a revolution and locked up. I later pulled the head and found a bolt in #2 or #3 I can't remember. It made a perfect indentation of a grade 8 13mm bolt head on the piston, right in the middle. The other end poked a dent right in between the valves. I put it back together without the bolt and ran it for a long time like that. I'm wanting to think that since your valves contacted on the outside edges of the pistons where they'd be stronger that you'd get away with a head.
Yes, a fine kettle of fish, indeed! I'm going to try to grind/polish the dings on the pistons to make them smooth (so they don't get carboned up, creating hot spots) and install another head.
When I first bought the car, I started pricing parts online and found an active item up for bid on a popular website. I placed a low bid because I still hadn't laid my eyes on the car and had no idea if I even needed a head. Turns out I was the highest bidder! The seller was a really good guy who shipped it out quick. He had a project car that he decided not to complete so he put the items up for auction. The head that showed up was perfect with all machining and valves renewed. I have a good head to put on there. Just have to buy some gaskets, oil, antifreeze and a water pump/timing belt kit. We'll see. Maybe this car will be alright!
That bolt inside the engine story is a good one. Lucky it didn't do more damage.
Great. Vid, best of all you sound like Clint Eastwood taking a head off. Brilliant, tone, cadence, I don‘t know what. Just doing mine, and I thought the crankshaft nut would be the hardest bit 😳
I used a little heat from a Mapp gas bottle on the crank nut. Then an air impact, it wasn't too tight. So you think I sound like Clint Eastwood?....Yes, it's me...I moved up here from Carmel, CA to get away from all the nosy fans but I'll have to move again now that my secret hiding place in Canada has been found out!
Also, thought to mention, I have many Volvo videos on my channel, some posted just this month. Also there is a playlist in the tabs at the header for the channel and one for all my Volvo videos so far...more coming all the time. Hope to see you in there digging around. All the Best!! Clint
Wait a minute.. did Canada also get the D5?? I thought that was Europe only!
I'm not sure if the diesel engines were available here in Canada??? There seems to be an abundance of the 5 cylinder 2.4 & 2.5 gas engine cars for sale, used, here but I rarely see any diesel models. Maybe just in Europe?
well hey, the airfilter box may probably be removed earlier ?? still watching to see this enligthening moment of where i get motivation to do my own xc70 ^D^D
Yes, I could have removed the air filter box at any time. I was learning this one as I went, however. You will have no trouble doing yours. Just make sure to unbolt the little line from beneath the turbo. I still haven't put this engine back together. It has been a busy year. I found a rebuilt head on eBay and that's what I'' be installing. By then, I'll have to watch my own video to see what goes where. LOL
Do you have any videos of you getting intake manifold off? Or getting the initial head cover(head gasket?) Off? Did you have to do anything to timing belt before removing?
I bought the car after the timing belt jumped. (The water pump failed) An unknown garage had disassembled the engine to the point you can see in my initial video. I will look through my video footage to check for the removal of the intake manifold and if it is of use, I'll post it as a stand-alone video. What I do remember is that to remove the intake manifold was quite difficult, having not removed one from this 2.4 L engine before. There is a large hose clamp underneath that holds a hose onto the manifold. That must be removed before you can lift it out. I remember having difficulty until I found and removed that hose clamp. Also, you must lift and twist the intake manifold to get it away from the fuel inlet line. Also difficult the first time.
If you are looking for tips to change your timing belt, there are several on UA-cam. I will recommend that you change the water pump, idler and tensioner with the belt, since any one of them can result in a catastrophic failure in this interference engine. They sell kits containing all the components. Buy a good one, not a cheapo. I will be installing an original brand water pump (AISIN) because the one that failed in this car was a cheap aftermarket one.

Best Wishes Everyday Projects
@@EverydayProjects thanks for input! I thankfully was able to get that manifold off(that hose was tricky!). Those 2 bolts to the left behind cylinder head head weren't easy either. you weren't lying about the "this is when you decide to sell the car" comment.😅.
I had the waterpump/timing belt/tensioner done when my volvo/bosch certified mechanic did the camshaft seals at 231k. I'm at 315k now, trying to decide if I should still put all those new part into it. I probably will since I'll have the belt off. Currently dealing with a bad exhaust valve, I'm gonna send the cylinder head off to machine shop. This is my "car soulmate" that I'm trying to keep him around as a hobby/sentimental repair project more than a daily driver.
@@remimcginnis7919 They're worth keeping and fixing, especially if the body is in good shape. They seem to hold their value. I would definitely change the water pump and anything on the timing-belt-train since any one of them will cause valve interference. I'm glad my video has been helpful. There will be more videos to come!
How did you remove your camshafts? K cant get them off
The camshaft cover has about 40 small bolts in it. This cover holds down both camshafts. Loosen the cover bolts from the outside towards inside, in several steps until you can lift the cover off. Sometimes, you'll need to tap/pry on a corner to get it to lift. Look on Amazon for the Volvo Camshaft/crankshaft alignment tool set. In it there are two tools that screw into spark plug holes that help install the cover. You'll allso need this tool set to lock the crankshaft and camshafts to properly time the engine on assembly. The kits are available for about $50 and are well worth having. Good luck!
How do you know where to set the timing when you pull the head
If you are worried about valves contacting pistons when the cams are removed, pull the spark plugs and turn the engine by hand until all pistons are slightly down. In my case, the valves were already bent. With the cams off, valves that contact the top of the pistons on a stopped engine will cause no damage.
Hi. I had my volvo 850-T5 -97 in for a change of cylinder head gasket and when assembled it made a squeaky sound and when checked the oil there was metal shavings. could this be it? is my baby totaled?
Metal shavings in the oil can be particles from worn bearings. If the squeak was there after the gasket change but not before there may be some part of the assembly causing the squeak, anything from a belt to a pulley, or camshaft to the timing belt. My main concern would be to monitor the oil. Change the oil and send a sample of it to a reputable oil analist lab for diagnosis. Any major parts supplier should be able to point you in the right direction to find one. If you want to continue to drive the vehicle, it is your choice but sometimes a worn engine will still run for a long time. Use clean oil and check for any more particles with a follow up oil analysis. You may be facing an engine swap or rebuild but you may be able to delay it depending on the severity of symptoms. Best wishes!
@@EverydayProjects the noise wasent there before and it dident come right away, they started and then run it alitle then came the sound and turned of the engine right away.
They will tear it apart again to check whats wrong butt i want to know what could have cause the metal shavings. Is it a minor thing or a big fail. Its my baby and i want it in top shape :)
@@Miffokorv Metal shavings and particles in the oil can be from the slow disintergration of the bearings on the crankshaft (either main or rod bearings). The general age, care, mileage and condition all lead to a decision on your engine. Was is spottlessly maintained with regular oil changes? Was it driven hard? Has the engine ever been rebuilt? How many miles?...the thing is, engines do wear out. You may be looking at a swap or rebuild. Metal in the oil is usually a bad sign.
@@EverydayProjects i have taken care of it more then my wife hehe i change oil before every summer and i drive it only about 5months a year (maximum 2000km) i always stay about 5min before take of and dont ride it hard, when stop i wait also for turbo too cool down. I'w been doing this for about 8years and the other owner did the same for 6years.
I'w never had metal shavings when i have checked the oil. So im assuming its something they have done when changed the gasket. Thank you for replying and patience
How installation of camshaft
A video of the camshaft installation and engine reassembly is coming soon to my channel. Watch for it! Thanks for commenting and watching.
Ok
Wouldn’t it have been easier to leave the exhaust manifold in the car?
The bolts on this manifold are difficult to access with the head installed. The easiest way is to remove it with the head. There are some turbocharger oil an coolant lines to disconnect and one connection to the exhaust flex pipe and the whole manifold and turbo come out with the head.
I found coolant in the bolts holes whats that means ?
Maybe the coolant got in there when the head was removed? Usually, it indicates a crack but consider all possibilities first. Did the head bolts get loosened before coolant was drained? I would send the head out to be checked for cracks. Best wishes
@EverydayProjects Thanks for your reply, the head has no cracks, and I actually empty the coolant before I losing the bolts but then I losen most of the bolt and got them out expit for few were stuck and took me few days to get the stuck ones out , that's mean minimum coolant got on the empty holes after I left it for few days .and probably that minimum coolant was in the head it's self and found it's way there to the empty bolts holes when I left it for few days because of the stuck bolts .
@@EARTHKEENING Let's hope that was the way it made it into bolt holes. Probably was. If the block was cracked you'd have coolant mixed in with the oil and also the cooling system could have oil in it. A cracked block usually causes the cooling system to be over pressured, causing boil over. If you didn't see any of those things, the block is good. Most likely, you're good to go on reassembly.
@EverydayProjects I have another question, when I removed the gasket , the block surface is shiny and nice and clean except of course for the old gasket left overs here and there , it has 70k miles only and the gasket wasn't bad , well I thought it was bad but I turns it has bad turbo made it smoke . My question is do I have to sand the block surface I checked and it wasn't wrapped or anything , can I just clean the surface with acetone and stuff and make it flawless and call it done ?
Note: I sent the head to the machine shop they surface it already .
@EverydayProjects yeah no my coolant was fine before I started the whole job , there were no mix in coolant .
Looking at that camshaft..it looks very bad. I'm no mechanic but it looks pitted and discolored.
Actually, the camshafts were reusable after a cleaning. The lobes were within specs and the bearing journals were good too. They had deposits on them from a common problem that occurs in some Volvo engines and that is the Crankcase ventilation system often becomes blocked resulting in crankcase pressure that moves a mist of oil continually inside the engine, often blowing out the camshaft seals. The previous owner was also somewhat slack on regular oil changes that led to deposits. I have videos upcoming showing the original camshafts put back into service on another head and so far, they are performing well.
@@EverydayProjects Cool, I want to ask if it's possible to pull the cam cover and later head without using the tool for the cam cover. As I understand it , improper removal of the cover leads to a cracked head or cover.
@@farmdve I haven't heard of the need to use the tool for removal only for installation, but even that can be done by slowly tightening all bolts in many steps.
I removed the cam cover just by loosening the bolts a few turns at a time starting from the outside and working toward the middle in several steps. I have a video to edit and post of installing the cam cover using the tool. Perhaps it's time for me to start editing that and getting it up on here.
@@EverydayProjects Will be nice, there are a few videos of pulling the head, but I think the cover always gets skipped yet is a super integral part of the engine and seems to be full of caveats one should avoid.
Cheater bar!!
You betcha !! These were tight !!!
