    Blown turbo, now what?

    It's a fair question, and one that I've gone back and forth on for the last 24 hours or so. I've done a turbo job before, I'm not afraid of it. But it will always need something. There are probably a lot of other parts that need to be replaced (especially in the suspension) and there are...

    Blown turbo, now what?

    Maybe. But what do I do with what's left after it's picked clean?

    Turbo sound got louder

    Well, the turbo sound changed a couple of weeks ago to something more "tinny", but only at rpms above 2500 or so. Yesterday the seal let go and the engine tried to run away... but I think I caught it before any damage was done. Guess I was hearing the death whine after all. See my post about...

    Blown turbo, now what?

    Well, at 197,000 miles it looks like my 2001 Jetta's turbo gave up the ghost. Was on the way home from work last night and put my foot down. The car TOOK OFF and then even after letting up on the accelerator the tach went to red line with lots of black smoke in the rear view mirror. I quickly...

    Turbo sound got louder

    Oil level is okay, but I had to add a quart a couple of weeks ago. I haven't pulled the intercooler hose to see if there's oil in there. I also can't detect any boost leaks, but that doesn't mean they're not there...

    Turbo sound got louder

    This is a 2001 Jetta with ALH engine. Does this sound bad to anyone, or just louder?

    Turbo sound got louder

    A couple of weeks ago my turbo became noticeably louder. It sounds to me like the same sound I've always heard out of it, just louder. There doesn't seem to be any change in performance. I got under the car last week and went looking for a boost leak to no avail. Interestingly, the turbo...

    High pitched whine while engine braking?

    {knocking cobwebs out of brain} I don't even remember this happening. I remember driving up and down that mountain road (and the subsequent damage to my brakes...), but I have no recollection of this whine. Makes me want to find a steep hill and drive down it in low gear...

    Oil feed line to turbo leaking at oil cooler banjo bolt

    Thanks. The washers were replaced with the line back in January. Plan A is to replace the banjo bolt and washers and hopes that's all it is. It's not clear why the bolt loosened or started leaking after so much time leak free.

    New serpentine belt idler pulley -- which way?

    Cool. That's what I did, but couldn't get the "hat" that's supposed to go on it fit and started second guessing myself.

    New serpentine belt idler pulley -- which way?

    2002 Jetta TDI: Last Friday the idler pulley, the one between the power steering and alternator sprockets, failed such that all that was left of it was the central hub and the bolt that holds it in. The new one is slightly different on each side, one side has a metal ring that sticks out...

    Oil feed line to turbo leaking at oil cooler banjo bolt

    A few months ago I replaced the turbo on my brother's 2002 Jetta TDI. Last Friday he sprung a leak between the oil cooler (or whatever part of the "engine" that this line attaches to, under the oil filter...) and the oil line at the banjo bolt washer. Tightening the bolt does not stop the...

    Help: Blown turbo replaced and now won't start

    Thanks for the link. I stumbled upon it the other day when I was searching for the timing belt procedure (again). I ran out of time last night to try this method, but I might take a look at it on my own car, if I can figure out how to move the IP sprocket by a sufficiently tiny amount... :D

    Help: Blown turbo replaced and now won't start

    Update: Short story: the car is running now, it was most probably a problem of air in the fuel line. Long Story: Ok, so I got the new timing belt on and tried to start the car, hoping that it was all just a timing issue. No start. Then I disconnected the line from the injection pump back...

    Help: Blown turbo replaced and now won't start

    I only disconnected three vacuum hoses during the turbo transplant: the turbo actuator hose, the EGR hose, and the ASV hose. I labeled each to be absolutely sure. I disconnected the connector between the valve cover vent and the intake air pipe, and labeled that as well.

    Help: Blown turbo replaced and now won't start

    The timing belt is very likely the next thing we will tackle. Most of the vacuum lines, along with the N75 and the accumulator have been changed in the last 6 months. The actual boost rises (or falls...) to meet the specified. I strongly suspect that there was a fuel problem at high rpm...

    Help: Blown turbo replaced and now won't start

    Seatman: Again, I don't think it's the cam to crank timing I need to be worried about, but rather the injection pump timing. Please correct me if I'm wrong. Yes, there is fuel at the injectors. There is a lot of air in the fuel there, though. Should I bleed until there are no more bubbles...

    Help: Blown turbo replaced and now won't start

    The intake was cleaned a few years ago and the EGR duty cycle was dialed to minimum at that time. The intake was grimy, but not plugged. There are no codes shown. I don't think that's the case since we'd probably be hearing really bad noises by now. I was thinking more along the lines of...

    Help: Blown turbo replaced and now won't start

    Remaining oil was drained from both the oil sump and the intercooler during the turbo replacement. The intercooler was cleaned. New oil and filter were installed. The ASV is functioning normally: open when cranking, closed when the key is turned off for a few seconds, then reopens.

    Help: Blown turbo replaced and now won't start

    My brother's 2003 ALH blew its turbo on the highway on Friday afternoon. Confirmed on Saturday morning that the turbo shaft between the turbine and compressor was broken and the intercooler was full of oil. We got a new turbo on Saturday afternoon, courtesy of IDParts.com. Spent the better...
