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.

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.

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?

[@alfaromeonoproblem]

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: kzbin.info/www/bejne/i6CWo5puos14obcsi=d2qCumz_68RoS7RV

[@Obv1ously]

Hello, thanks a lot for these videos, they are very helpful to a lot of "home mechanics" like myself :) Seems like lack of maintenance killed my friends 1.6 TS. Consumed a lot of oil (about 1l per 1000-1500km) and now has low compression in 1st cylinder. What do you think could be the issue? Havent tested yet if its bottom end or top, planning on adding a bit of oil into the cylinder and seeing if the compression improves. Is it possible to replace the piston rings with the engine in car? Thanks again and greetings from Czech Republic :)

[@alfaromeonoproblem]

Hello. Burnt valve is the number one issue, mainly with hi oil consumption. You can take care of the ring with the engine in place, but the issue is not the rings, it's the bore, out of round... So, oversized pistons will be for the best.

[@Obv1ously]

@@alfaromeonoproblem Hello, thank you for the quick reply :) We will do some more diagnostics then and try to figure out if its a valve or bottom end issue. Engine has only about 180k km so hopefully the bores will not be out of round too much..

[@alfaromeonoproblem]

@Obv1ously check with the bore gauge before honing

[@billy.the.maker.]

Love it!

[@karlos1060]

I think these engines are still good as long you take care of them. I drive a 2004 156 1.8 on LPG. And it uses 1 liter of oil every 1500 km aprox. I use Valvoline 10W-40 semi syn. And try to change the oil every 10k but some times it was a bit longer. But at least every year. With LPG you have almost no carbon build i believe. Last time i saw my engine "naked" with a timinbelt replacement it looked very nice. It has almost 305.000 km done and still starts very well and drives well in think. I change sparkplugs every 55K as well as the timinbelt. I use NGK sparkplugs. Would you have other advise to do on these engines to stay healty as long as possible? Greetings from the Neterlands.

[@alfaromeonoproblem]

Hello. That is a lot of oil consumption, it may burn a valve or two. Try 10w60, that's all we use here

[@karlos1060]

@@alfaromeonoproblem I did use that before but no difference in oil consumption. Maybe in best scenario 200km extra. I don't think it will make a difference using 10w60. And what do you mean it may burn a valve or 2? Does oil usage cause vales to burn? I haven't had that so far and the engine still runs and sounds healthy. No misfires, no engine lights, good clod and warm starts and still enough power. (for sure not 140 anymore)

[@karlos1060]

@@alfaromeonoproblem If i am not mistaking the 10w is the cold spec and the 40 or 60 the warm viscosity. 60 is a little less thin and a little better lubrication compared to 40? Thanks for the answers! Much appreciated!

[@alfaromeonoproblem]

@karlos1060 hi blowby causes issues in valves and valve seats. It can create a bad seal and it can eat away the valve

[@alfaromeonoproblem]

@karlos1060 yes, correct

[@BK-it6te]

When you resurface the cylinder block what happens with the piston hight ? Do you take of from the piston hight ?

[@DashCamSerbia]

I think just thicker head gasket is used.

[@alfaromeonoproblem]

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.

[@TheScareyou]

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 ?

[@alfaromeonoproblem]

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

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?

[@alfaromeonoproblem]

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: kzbin.info/www/bejne/baavkGmsoKqKhrc

[@jal1797]

[@doraexplora9046]

@@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!

[@alfaromeonoproblem]

@doraexplora9046 that may be a bit risky for the bearings and cylinders. But if it works, great!

[@doraexplora9046]

@@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.
