- Опубліковано 1 чер 2023
- Hello guys! Why was this engine going to scrap!? Lack of maintenance!!! It all started with the lack of antifreeze maintenance! With that, the head gasket falls apart and with that, in its replacement, the lubrication system was compromised! Take care of your cars by doing preventive maintenance!

Thanks for yet another great video! Obrigado!
Thanks for watching! Obrigado!
Really good.
Thank you very much!
Excellent
Thank you very much
Love it!
Nice work, good, clear explanations. I've got a couple of v6 166s and so I like to gather info on maintenance from guys like you.
Hello. I have a bunch of videos for v6 busso. Take a look:

@@alfaromeonoproblem Thanks
Hello chief nice video❤ i have an alfa romeo 146ts 20 years now but unfortunately i was in bad luck ihad a temperature issue (thermostat)and i replaced head gasket but after that it was a nightmare, oil leaking, misfire, high temperatures and lots of €€€$$$
With all that oil starvation, that motor must have sounded horrible! BTW! Fantastic and interesting video's. Plus your English is getting better all the time!
Eventually do a motor refurbishment and assembly vid. This one with the worn out pistons and overheated con rod would have been perfect to see how things are repaired.
Hello. Thanks a lot for watching and for the feedback.
This engine is being sold for parts. I need the money for the channel.
I would love to see this engine completely refreshed/rebuilt also...no one has done one and I for one would be interested in buying a well put together engine for my own car.
@ppf_services hello. Unfortunately I cannot do it, I cannot afford it.
Once I have one from a customer, I'll do a video for that.
Magic engineer, quite electric fuel efficient however couldn’t fix the warning
Do you have like an eBay store where you sell parts, or is it just for Portugal?
My TS 1.8 engine has 300.000 km on it, and it is still doing fine. Just some minor maintenance from time to time, and also changing the oil frequently will make sure it will last.
Hello. Yes, the best maintenance on those is frequent oil changes. Thanks for watching
Geees. I've never heard of a TS motor lasting that long. You must be using the Selenia oil and not an aftermarket oil.
@@doraexplora9046 Actually no, I just very frequently change my oil, that's it.
@doraexplora9046 no. Here in Portugal we use 10w60 on these.. it is excellent for our climate.
@darthgator639 very important to avoid crusting and varneshing
Great videos very informative..Quick one. 2.0 L 16v 147 twin spark. Running awful and appears to be misfiring at idle and all through rev range Smells of fuel and wet fuel out of tail pipe. Did live data diagnostic and I have zero spark advance. Had ALL new injectors plugs and coil packs, and Maf replaced plus compression test, all good readings before I got it.. O2 sensors are reading high voltage and not switching until one very deep switch when I blip the throttle ( rich i believe) Going to change out the crank sensor as obviously not right but incase it doesnt fix the issue what else should I be looking for?
Hello. I would say a cracked coil pack. But it's that is new, the most fundamental thing on these engines is proper timing. Something that I'm my experience is always very bad.
You can check and correct it:
ua-cam.com/video/Uo3rg8mhEkU/v-deo.htmlsi=d2qCumz_68RoS7RV
@@alfaromeonoproblem appreciate the reply. Yes been through ignition, injectors coil packs sark plugs new etc. variator is noisy for sure so next port of call.. cant understand why there's no codes or mil light
Can you do one video for 159 2.4 jtdm
Is there a drain plug on the block to drain the coolant?
Hello. No, there is not
Hello and thanks for the video?I have problem with misfires on my 147 twin spark 1.6 105 hp engine especially in the morning.The diagnostic machine shows nothing of problem.Pump fuel is ok and the injectors are ok.The sparks were replaced before ten years but I have done only 40.000kms because the car was at parking for years.I have done the main service with belts,oil and coolant.I have noticed increaded oil burning too.The car goes strong as always though.What could be the problem?
Hello. You may have problems on the spark plugs, oil on them.
That and the timing may be a bit off.
Those ten years not working it may have the piston rings stuck.
See if this helps:
ua-cam.com/video/7uL_6vkEWPU/v-deo.html
Yes that is a do 2 early oil changes and maybe use some flush liquid before next oil change./It was 3 years but I had started at idle some times.Thank you and keep on the nice work!
@@jal1797 I've used kerosene instead of oil at idle for ten minutes and completely freed the rings, improved compression, freed the hydraulic lifters, reduced oil consumption and made the oil clear again. However, don't rev the engine!
@doraexplora9046 that may be a bit risky for the bearings and cylinders. But if it works, great!
@@alfaromeonoproblem If you are concerned then thin the oil down with Kerosene and flush out all oil galleries with that. I've done this many times over my 45years of playing with cars and the final result is nothing short of breath taking.
1. Only do this at idol.
2. Stop as soon as, or slightly before the engine has warmed up.
The other thing I've done is rather than fully disassembling the motor. Use a VERY HOT water pressure blaster on the assembled motor to clean it and let the hot water evaporate off. Remove the pistons and clean the pistons and rings. Thoroughly lubricate everything with fresh oil. Build up oil pressure before starting the car.
This usually cleans out ALL issues that were due to infrequent oil changes and carbon build up.
I have a mint condition 156 2.0l with only 90,000kms on it which I intend to do this to and replace ALL gaskets when done.
When you resurface the cylinder block what happens with the piston hight ? Do you take of from the piston hight ?
I think just thicker head gasket is used.
Normally it stays inside the factory specs. A thicker gasket is common on diesel ones, but on gasoline ones not so much. Taking out the top of the pistons is also a good way but the removal is necessary.
I just noticed that my dipstick tube seal below have completely burst out and the dipstick tube is a bit higher that it should be i think [popped out]. it causing a pretty big oil leak when revving, and the oil goes on the cat creating burning smell and smoke.
Can this also create a vaccum leak ? i know its far from the crankcase though. Can it be the reason why my car is running rough and very low power at low rpms sometimes stalls. MAF data seems fine, as well as o2 sensors. tested for leak from intake but all seems good. should i dig deeper ?
Hello. I do not think it's the reason why, but glad you did find it.
Check out the engine timing and in that, check out the coils too
Hey man, had a lot of oil consumption and now looks like one of my piston rings went since i lost compression on one of the cylinders. I'm wondering whats your opinion, whats the best way to rebuild it and eliminate oil consumption and make sure it lasts, slightly bigger piston rings and honed cylinders? 1.6ts
Hello. Yes, oversized pistons is the best you can do. And use 10w60 at every ten thousand Kms.
@@alfaromeonoproblem you think there's a way to fix it without changing the pistons though? Cant piston rings on their own be slightly bigger? Seems out of my budget to replace all the pistons tbh
@goxy287 take it to the machine shop to be measured after a hone or two. Is it still within tolerance, go with the same pistons and new rings
@@alfaromeonoproblem alright thanks a lot
Whats the name or number of tool for screw of the head,is it torx ,what number?
Hello. It's a Ribe. Number 13 if I recall
The head looked quite dirty, lacking fresh oil changes?
Yes, it was the lack of maintenance that killed this engine actually.
Both oil and coolant
@@alfaromeonoproblem yeah looked like a basic lack of oil changes as the main culprit. I have a 2.0 T-Spark on near 100k miles and the inside looks much cleaner, I just changed the cambelt do had the rocker cover off
As far as i know the 16v TS engines are not related to the bialbero. Maybe some lay-out similarity, but only a head developed by Alfa, the rest is Fiat. The 8v TS engines are real evolved Alfa bialbero engines
Hello. Yes, you are correct
@@alfaromeonoproblem noproblem :) great video by the way. Almost forgot that.
Which oil should I use? 10/40 or 10/60?
For climate like Portugal, 10w60
What about oil pump?!
They are very good usually. Do you want a video for that?
@@alfaromeonoproblem I have experience with 2.0jts the oil pump having the inner plate loosen and the oil pressure drop.
That is very odd on these engines
is it me or those bolts are very very VERY LOOSE!
Hello, they were the normal for these engines, I just have a very long breaker bar.
Excellent video, I love this; i am getting knowledge I couldn't get by simple verbal explanations. Your mentioning the hydraulic lifters made me think of a sound my car was making, a ticking sound in the upper engine bay, what does this sound to you?
ua-cam.com/video/q89Xwd4DJXk/v-deo.html
Hello. I'm glad you like the video. In your case it seems to be starting to have a lifter noise, yes
Had this engine on my 145. Pile of junk of a car. Fiat couldn't do worst.
Variator issues. High oil consume & fuel consume too.
Never italian car anymore.
