Been reading and reading and reading the forums for last 3 weeks and not finding anything that has definitively helped.
Purchased a 2003 jetta tdi with 308k that is rust free with decent interior knowing of mechanical issues for a little bit of nothing. After test driving the car I noticed a pretty bad misfire that was erratic. After popping hood I noticed deisel fuel around injector on cylinder 4 and air bubbles. Thinking an easy fix and since the car came with a spare set of injectors that the owner said were removed from a low mileage car of the same year, I jumped on it.
So here I am. New to this forum but not new to diesels as I own 2 duramax's, one of which I've worked in more than I care to talk about.
Driving the car home I had to deal with the intermittent misfires and blueish white smoke and a leaking flex pipe which after about an hour about killed me. I swapped the injectors the day after and fired the car up. It missed from the get go and was putting out plumes of white/blue smoke.vtried to drive the car and was near undrinkable. No power, stumbling and missing. Here is what I have done.
Checked compression
All 4 cylinders around 400 psi +-10 psi
Pulled lower intercooler hose. Oil present but not significant as stated in other posts I have read.
Original injectors dropped at local Bosch specialist, tested and deemed they no longer automize fuel and are leaking.
Pulled charge pipe and looked into egr. Egr appeared coated in oil. Egr pipe from egr cooler to egr found to be blocked by black oily/carbon deposit.
Turbo has no side to side play on the turbo wheel but turbo wheel seems "stiff"
Pulled valve cover everything appears to be in pretty good shape.
How much oil is to much oil to indicate turbo failure? To me, there should be now oil at all. But I read on here that some is normal. Never heard of such a thing.
Where to head to next? I know I need to get injectors taken care of but would that alone be causing all these symptoms?
I do not have vcds and purchasing would be more than i paid for the car. No codes currently on car. Traction control light is illuminated however.
