Exclamation Turbo factoid

I learned something new about turbo's today. I decided to inquire about my failed 2.8 turbo with the turbo shop (Turbo Exchange & Performance in Concord, NC) looking for a causal reason why the failure occured (post mortum). They had to locate the turbo as I had never got it, but the specialist asked me, "first tell me if your shop replaced the oil feed line to the turbo?". ummm, I don't think so. One didn't come with the kit that I was aware of, nor do they normally (although I never actually saw the kit). The specialist explained that the number one reason turbo failed is because of blocked oil lines, and that is almost always caused by oil crystalizing in the oil feed line, since most feed lines wrap around the engine block and are super heated all the time. He said that when that crystalization starts to form it either blocks the line starving the turbo, or the crystals break free and plug the oil feed holes the line taps into. I asked him if I should pull the line and clean it out and he said no. If the line was blocked, even a few small crystals that were not caught when cleaning it out would now be potentially loose and free to flow into the turbo and block it. He also said that if the line was completely or partially blocked, that my new turbo would likely already be suffering from some damage at this point.

So off I am inquiring to M&D about a replacement line. The 2.8 manual explains how to pull and replace the turbo, but doesn't mention replacing the oil feed line each time. I'm guessing the Land Rover manual for the 300 TDI probably doesn't mention that either. What is clear because of this normal aging risk, replacing the oil feed line when replacing things like the coolant hoses would be good preventive maintenance, since the feed line is just a simple metal line with threaded ends, and the turbo is about $2k to replace!

I'm waiting to get the call back from them on when they found my dead turbo and give me the reason it failed, but I'm hoping it wasn't a blocked line. Anyway, hope someone benefits from this tidbit, and don't be me. New turbo is rocking and showing no signs of illness, so keeping my fingers crossed.

I'm going to pretty much trust this shop, as their business is with all the northern Charlotte auto shops, and are located not far from the Charlotte NASCAR speedway. Everyone in that area lives and breaths cars.

Why don't you just have a line made locally? Or make one yourself. Clogged and/or kinked return lines are also another common cause of turbo failure.

Good information but I wonder if there isn't a good way to prevent it from ever happening to begin with. I'm about to send my turbo off to be rebuilt. When it goes back on I would sure like to do it with some confidence that I've done everything reasonably possible to insure that doesn't happen to mine.
