Howdy, Y'all!

I finished replacing the water pump and timing belt on Gandalf. While doing so, I also performed checks and services on every part of the engine on which I could get my hands. I found one potential problem area that could have caused loss of the car.
The turbo's oil drain line was routed so it pressed against the power steering hydraulic line. 41,000 miles of driving caused the drain line to abrade the hydraulic line into the inner webbing. This had the potential to allow the hydraulic line (with considerable fluid pressure) to fail. This would result in hydraulic fluid spraying over the exhaust manifold and turbo. I re-routed the drain line and hydraulic line. I will be replacing the hydraulic line in the near future.
This is something you should check to ensure the failure mode does not exist for your engine.
Note: this is a '91 with 1.6 liter engine and a modified FMII system.

Cheers!
Barry
PS. Hope you all had a wonderful Christmas and wishing you a Happy New Year!

I had the same thing happen to me ... noticed it before the trip to CO for
the open house. I put a 30 degree angle out of the pan and bent the oil
drain tube from the turbo about 15 degrees. Shortened the drain line and it
clears everything by at least an inch now.
