I picked up a CRD on cragislist that had a bad turbo back in november? december? sometime like that, it was cold and wintery. Its been sitting since then waiting for me to get around to working on it. I debated back and forth on turbo options before I decided on the stigan based on price point. I bought it off of amazon with prime and as such it came fairly quickly.
The turbo seems pretty good quality in terms of fit and finish. Nothing looks cheap or ****ty about it, dimensionally it fits in perfectly.
I got some metric studs at my local hardware store for the oil drain pipe bolts. I installed new copper crush washers on the banjo bolt, and new seals on the return hose. The studs did make it a little harder to get the turbo oil drain pipe back on.
You basically have to get the return oil line off in order to unbolt the turbo, this also means if you install studs for the turbo oil return line that it will be harder to get to the nuts that hold the turbo it. It's possible, but harder to do with the studs in.
I used a couple of new copper nuts, a couple of the nuts stuck to the studs and became bolts, so those were reused.
Overall it took about 3 hours to install. Not too bad all things consider, but I would not call it an easy job. I think the studs saved me time and frustration putting it back together.
Since the oil turbo failed with a broken shaft massive amounts of oil were able to fill up the exhaust. After I got it running the pooled up oil started making its way out - and making a massive smoke cloud. It took come effort of warming the engine up - getting oil to start dripping out, and shutting it off before it blew too much smoke. I got out at least a quart this way and then went for a drive at 9pm when it was dark to blow out the rest. After a short drive at operating temp the oil was finished burning out. I think I made it much better by getting the oil to drain out before the drive. It really can make a massive amount of smoke - been there before.
So with the oil smoke cleared out it was now blowing pretty good diesel smoke. It would eventually boost but was way too slow off the line. It was also triggering a 0299 underboost and a 1250 vac control circuit open. I had heard and seen the other photos where the stigan linkage was incorrect and caused underboost, I was not looking forward to trying to adjust the linkage or swap actuators around from the old turbo.
I decided to pump the actuator with my hand held vacumn pump. After confirming that it was indeed moving and that none of my lines had a leak I decided to watch the "Desired Boost" vs "Actual Boost" on my DRBIII went for a short drive with me riding shotgun and watched the values track. While the actual lagged desired it usually ended up matching with a second or so. When we finally had a chance to do a full throttle pull we noticed it spooled right away and the power you would expect was there. The black smoke was also gone. I believe the actuator was just stuck and took me pumping it by hand in order to free it up.
Managed to snag an emissions testing appointment later that day so we took it on a good highway drive, after getting it up to 85+ for a mile we pulled off at an exit ramp and then got back on the interstate for another high speed pull, this time it blew LOTS of black diesel smoke. But all subsequent pulls the smoke was gone. I figure it needed a good hot burn to really get some trapped junk cleared out.
So thats all, for now. Gotta drive it some more in the next few days and make sure it seems ok. Then my dad will be driving the CRD out to california from colorado.
