My passat started making a noise today, was driving down the freeway and heard it when I was pulling up to the traffic light. Pulled over in a parking lot no low oil pressure light, no over temp light, proper level of oil and coolant. Noise gets slightly less noisy when I press the clutch pedal in.


History of the car that I know, bought it last year with 253k miles, 5 speed stage 2 tune and was told a bad engine by the previous owner, he claims to have run it out of oil said the oil feed for the turbo blew, he put a new stainless braided one on it. I pulled valve cover,oil pan and oil filter, no metal shaving any where and rod bearings looked good, has the balance shaft delete. Pulled the fuel filter and it did not smell like diesel drained all the old fuel from the tank and refilled with clean diesel and sounded better.

I have put over 20k miles on it in the last year, 6k of them in the last month. Any idea on the noise? I haven't had a chance to dig into yet, should be home tomorrow afternoon. Also when I was doing the work when I first got half of the bell housing bolts where missing, wonder if a flywheel or clutch bolt could be loose?

From your video it's hard to say... If it were my job to diagnose, I would use a stethoscope to listen and find out where the noise is coming from /loudest. If the noise is loudest at the bellhousing, flywheel or clutch (DMF?). Loudest at the valve cover or block? Start opening up the engine...

Wow, that does sound pretty bad... I'd narrow down where the sound is coming from. Do you know if the balance shaft has been deleted or converted to geared drive?

It has been deleted, when I started it to load it on the trailer the car sounded normal, it only ran a few minutes. Got it home and looks like some bad lifters, will update once the cam is out.
