damage valve guide is very tricky when it come in rebuilding head,never know how long the new sleeve will last.,,,now we know that bronze is wrong > great video thanks

I have a 2000 jetted tdi. After every start the turbo boost doesn't kick in until rpms reach about 2250.this is a consistent thing happens every time for the last 30k miles at least. Once started and revved to that 2250 rpm the boost is there immediately until shut off.then the process starts over again.

hats off sir

Excellent investigations and a very tricky situation! 👌🏻

Great Video! What year is the VW Tiguan you were working on?

Amazing video, you were thorough and paid so much attention to detail, defs deserve a subscribe and like, I think im having a similiar issues, I have the same engine in my a3 convertible, did a rebuild,, changed, spark plugs, coil packs injector, line boared the head, schemed the head, replaced rings and valves as well as bearings after cutting the krank as i hit a bearing knock, im gettting a misfire on cylinder 3 but when checking compression, it is low on 3 of the cylinders, the misfire appears mostly on idle and at low revs but when driving the car its fine on top, VCDS is kicking out a camshaft retard error but the variator solenoid is replaced as well, my mechanic is thinking the valve clearances could be incorrect as we did not adjust them considering the fact that we have done so much head work do you think this could cause such a result?

You can take an old OEM guide and sent it out to a laboratory that does metal analyses. This will give you all the metals in the guides. Very easy to do hardest part is having the instrument to run the test.

Very interesting, I have a headache though. Been trying to diagnose for many hours. I have a cylinder 1 misfire condition. P 2302 p 0301 code. All spark plugs and coils are new. Engine still vibrates.

I have a 2009.tiguan, issue is multiple miss fire P0300. Check engine on & EPC light on dash. Engine wont start, i smell gas, new coil and plugs 2 months ago, although found a crack on a coolant line, that run down in the front of the engine, i wondering if my heads are gone? Not sure if its worth fixing. Just bought the car for my sons 1st car and its not looking good.

NICE DO A VIDEO SHOWING THE TESTING AFTER YOU ERASE THE CODES REPLACING THE HEAD

I think a contributing factor is how hard that engines pushed maybe when it comes to turbos failing not everyone of these cars blows the turbo not everyone of these cars blows a timing chain at same mileage it’s just if an when

well diagnosed ... but i agree with you not the best engine to be come across with issues...

It started with the 24v VR6 motor. Their gas motors have been shit since then. Dieselgate shows what the culture was like at VW engineering.

hey dude !! excellent videos! but what about de turbo exauhst valve? and after that head did miss the codes? thaks a lot for that videos.

Thanks!

what year is this one from?

Is the motor supposed to run with that ticking sound?

Good info about the guides... but not good that you had to find out about it this way. =(

You could install integrated engineering valve guides..

After replacing the head was the issues resolved???…

Ive changed the plugs and coil packs and my cars still popping an engine light for misfire not sure what to do ive already spent like 300 on this problem for it to keep happinging

Is the turbo working

Any ideas as to what the problem/solution might be?

🤘🏻

How much is the dealer head?

Amazing how many problems. Do it all lol🍺

I need to get rid of my Tiguan

This makes little sense, it needs to be a helluva leak to cause a misfire. This vehicle does not look old and this exhaust valve issue should not be happening.

Tdi engines or bust.

that machinist knows of all these problems and 1 DIDN'T TELL YOU and 2. CONTINUES DOING IT SINCE HE JUST DID YOURS....Find a new machine shop!!!
