Do you have to pre lube a rebuilt turbo somehow before first start up, seem like you should......

William Rogers......

I would imagine that cutting off fuel and cranking the engine with the starter would suffice to pre-lube the turbo bearings...

I had a 1986 740T that I bought new. I donated it last year with 291,000 miles on it and the original turbo. It was not water cooled BTW. Proper oil changes and/or using synthetics will prolong turbo life as well as a prolonged idle. You do not want to drive really hard and then pull over and turn off the engine. The water cooling will do most of the protection but the regular oil can cook.

The way to check the turbo is to pull off the inlet hose, from the AMM to the turbo, and turn the compressor impeller. If it's smooth and spins well, you're ok. If it's gritty and has play, rebuilt turbo time Check out http://www.cherryturbos.com/ if you need a rebuild.

Also, check the underside of the inlet hose at the turbo for deterioration due to oil bypass from the crankcase. If it's soft and spongy, time for a replacement.

Make sure your intercooler hoses are not cracked or torn. If you are experiencing lower boost levels, one or more may need replacement.

That's all for now.
