VW 2.0 TSI Engine Teardown after failure

[Cujet]

Some grubby intake valves.

I've never understood why manufacturers place parts like that screen, in a way that can cause it to come loose and block oil flow. By now, we know how to make engines.

i always imagined the author of the classic VW DIY books to look something like the fellow in the video.

Sure thing baby face.

His moustache is probably a better mechanic than you.

The guy knows his stuff, no doubt about it.

Same reason the keep putting plastic filter in DI injectors that burns through, turn to ash and clogs the injector I guess. The thing is its not just VW/Audi, others have exactly the same issue and they still don't put a 10c SS filter in that cures it. Got to burn through the old stock is my only guess.

Engine designers from every Make have thrown in a wrench or two at one time or another. VW just gets chastised more on this board.

That is the guy who said that new Tiguan finally feels on the road like "real" VW.
Who are customers of new Tiguan: buyers of RAV4, CR-V etc.
Who will not buy new Tiguan: People who had 1st generation Tiguan.

He mentions an oil screen--what's its need, if it likes to migrate throughout the engine and do damage?

Interesting way to get out of using a woodruff key on the balancer. Is this a cheaper/better way of indexing?

Doesn't look like that engine was living a great life, seems like a lot of carbon and even oil build up in those cylinders.

Edit: dawned on me, the oil on the engine is probably from oil changes, duh.


Its a matter of poor maintenance and not replacing the old style tensioner with a revised version per TSB (15-12-01), lots of engines from every manufacturer have hit the valves on the pistons for various reasons.
Running it to death and not taking care of it then blaming the manufacturer is just foolish. Even a good indy will look for TSB's and see if any are applicable to the car he is working on and inform the customer about addressing it. If you do your own work a short term subscription to AllData will give you TSB's or just call the dealer.

This is an relatively easy job on this engine if you do it before the chain jumps, it will rattle before this happens, if someone chooses to ignore it then its on them really, I agree they should extend the warranty but they didn't so you have to work with the hand you are holding.


TSB

Not only that, it will throw CEL too.

If the car has already started throwing cam/crank correlation codes, it is often (but not always) too late.

The new Tiguan is better in every way compared to the previous parts-bin Golf-with-a-lift-kit.

I hated the first-gen Tiguan.

I always thought it was a Bosch thing. Are the SS filters an "aftermarket" solution?

+1 you want to catch it before that if possible. Early on its an $82 part and not a lot of labor. GM 2.5 engines mid 2000's had this problem also and also only a TSB not warranty. This is what happens when they dumb down vehicles, too many people are not in tune with the sounds their car/bike rolling sofa and entertainment system is making anymore.

Very cool video. Interesting compact design on that engine. I believe my SILs Audi A4 she had some years back had that engine. Pretty fun 6spd MT car to drive. Did he mention how many miles were on that motor? That external oily film woulda drove me nuts, but I'm sure who ever owned it never popped the hood.

That gent is a heck of a tech!

Thanks for this thread...

Actually this one is pretty early.
Rattling appears before, but will throw CEL before it is too late.

Actually EA888 it is not too late when CEL shows. BUT, there is only so much time before things go downhill.
I did that. Changed it preemptively. I have to actually call VW because I think they will cover some parts of expense related to this.

Thanks for that info edyvw.

Yes they are. Not exclusive to Bosch, I had a sets here made by other manufacturers with them as well.

Off your meds or drinking too much? High quality informative video by a person who clearly knows what he is doing. 153k views I am glad he generates some revenue for his effort of educating folks.

i believe that was a tensioner failure that now has been uprated. many owners don't even know they have an interference fit engine with a belt or chain drive. belt changes are earlier + changing the complete system is best because as shown the chain did not break but tensioner failed. there was some chain stretch that could change performance but no bent valves.
