  • This 2.0t TSI Volkswagen GTI engine had catastrophic piston failure on cylinder 2. In this video we walk step by step on a quick diagnosis for bottom end engine damage. We will also remove the 2.0t TSI engine from the GTI for engine teardown and inspection of the piston and the cylinder wall to see what the proper repair is going to be. #humblemechanic #vw #GTI

      Not really for all TSI if I'm not mistaken. 2013.5+ (Gen. 3) don't tend to have these issues quite as much as the Gen. 2.
      Apparently Volkswagen decided in order to reduce fuel consumption they needed to reduce friction inside the cylinders, hence they used thinner piston rings. Up about 80-100,000km these wear out (as you said, specifically the oil control ring which gets clogged up) and causes excessive blow by because the rings cannot deal the combustion chamber properly.
      Extremely high oil consumption (1qt per full fuel tank), loss of power and maybe higher fuel consumption are common symptoms.
      Charles pointed out this issue was more common in longitudinally mounted engines than in transversal ones, more common in Audis yet also in some Passat, Jetta, Tiguan and Golf.
      He can probably explain with far more details and specific models affected for sure.

  • @aaronblankenship1741
    @aaronblankenship1741 Před 5 lety +31

    You can destroy any motor in any vehicle if the tuning is not applied correctly. Mistakes can easily be made from selecting the wrong octane file, meaning you pumped 89 octane fuel into the tank (maybe on purpose or accident) but your flashed to a 93 octane is required map, etc. This scenario can cause catastrophic knock/detonation events if the ECU does not pull timing or enough timing to save the motor. Also, what can cause this is the end-user simply selecting a map that absolutely requires supporting mods like an intake, aftermarket downpipe, upgraded front mount intercooler, etc. Who then chooses to not do so and runs that "Stage 3" map on a bone stock car. Yea these and other mistakes will doom any motor when you start playing with tuning and don't know what you are doing. My personal experience with the older version of this very GTI motor when tuned and taken care of correctly has been a great experience with zero issues. Everyone has their own experience I guess and I'm sure some factory parts do fail for reasons that don't seem right or fair but to say "TSI motors suck", ehh not so much.

      Change your oil and filter really regularly (at least every 7500 miles) and - if you use your engine power regularly - don't use that 5W30 oil with the VW 50400/50700 spec on a tuned engine. Go for a 0W40 or a 5W40/5W50 instead that meets the VW 50200 and the MB 229.5 spec.
      Also, always warm up the engine and cool down the turbo after running at higher speed. High-Octane premium fuel might also help keeping the injectors clean. Because when they start to lose their spray pattern, they will start to wash off oil from the upper cylinder wall.

      @@user-vo3ku2sf2d over here in Europe, Volkswagen advertises 20k miles drain intervals when using engine oil according to the VW50400/50700 standard. The drain interval drops to 10k when using any other approved engine oil that does not fulfill the 50400/50700 standard. I used 50400/50700, drained every 7.5-10k and my engine was still running strong after 150k miles without any noticeable oil consumption. IMO, a 4k drain interval is a waste of money unless you operate your vehicle under extreme conditions like lots of short-trip city driving or racetrack driving - which would most probably justify changing the oil after a track session anyway.

    Really enjoy these "how to" (eg, test compression) explanations! Also, your video quality and lighting were phenomenally good in this video. Suggestion for a future video: how to check the status of carbon buildup without removing the intake manifold. I've heard it's possible to use a $30 Chinese borescope (hooked to an iphone or Android), and peek at the valves by taking out a spark plug. But not sure if this is actually a practical/feasible method. Seems like it would be hard to really visualize the back of the intake valves. Do they really extend far enough down into the combustion chamber for the borescope to see?

    One of the commenters mentioned it looked like LSPI damage. My understanding of LSPI is that it's basically a random diesel like event caused by excess gas droplets mixing with oil that effectively lowers the octane. Manufacturers counter this effect by spraying excess fuel to quench the cylinder temperature during pressure spikes. This damage could be related to the tune or just bad luck.

The boreholes above the oil collector ring which should transport oil from the cylinder wall through the piston back into the oil sump are too small in diameter and can potentially suffer from clogging due to carbon deposits and oil sludge if the car ran on the 15k-20k oil service cycle.

  • @phillipjones3439
    @phillipjones3439 Před 5 lety +20

    I think this is due to over speed. I have heard of four examples of piston failure in these engines. The engine is built as a 1.8 and 2.0 capacity. The 1.8 is already a longish stroke engine 3.25 in Bore x 3.31" Stroke. The 2.0 uses the same Bore but takes the stroke to 3.65". This is a long stroke motor. The rev limiter remains the same in both engines but the piston speed in the 2L engine is much faster. In untuned engines the system copes but seems to have little in reserve when engines are tuned and slightly higher crank speeds used. The failure where the skirt breaks away below the Oil Control Ring is typical of a speed overload on a piston. As if to confirm this, I, and people I know have never heard of the 1.8 failing in this way. Very interesting.

      DSG would not allow an overrev. We had a few 5.0 JLR engines break pistons like this, it was found to be an assembly issue due improper ring installation. An engine like this could last 50,000 miles + then it would eventually break a piston. Forged internals are not Vibranium they can break under stress just as much as anything else.

Another note: I saw an engine apart fron a 2016 Golf ( 1.6 ) it came out of the car because below the pistons are valves spraying oil which open at interval related to the piston location; one of these valves was stuck open causing low oil pressure/engine light and then limp mode. So many tiny passages for oil to pass; it need BE CLEAN
