How did the crank gear seal area look? You may have to install a seal sleeve if the crank gear seal area is worn or pitted. I have some notes and nobody makes an "exact" fit sleeve, but there are some that can be modified to work per my notes.

Some shorten the spring in the seal to increase lip tension, of course this shortens the seal life, but seems to work for some.

Note using a 60-63 bellhousing on a 64-69 crank will position the seal just at the outer edge of the seal area and can leak.

Good luck.

hi guys, the car has been running really well so I took the wife out for a spin. Lots over power, and the boost comes up really well too. Then all of a sudden I smelled oil burning, and felt a loss of power.
Pulled over and saw a lot of oil under the hood on the shroud on the passenger side, and oil dripping on the ground.
Made it home ok and cleaned it up a bit. It was idling a bit rough too.
Next day I did a compression test and found the number 1 cylinder at 48 psi. The rest are between 140 and 115.
Will have to investigate further. I was thinking maybe head gasket.
What do you guys think?

The turbo experts can comment on issues of oil leaks with turbo oil lines, BUT with loss of power, low compression on one cylinder AND oil all over engine top shroud I would look for excessive piston blow-by. Start the engine with the oil filler cap OFF and look for excessive piston blow by into crankcase. If a lot of blow-by comes out the oil filler neck, then that would suggest a ring or piston failure. If so you can do a leak down test to confirm.

1. You sure it is engine oil and not GL-4 axle lubricant?
2. Did you put sealer on the flywheel to crankshaft bolts?
3.Was there a large groove on the crankshaft seal surface where the old seals rode for years?

UGH!

Unfortunately, the description "loss of power" "oil on shroud" "number 1 cylinder at 48 psi" is almost verbatim what i experienced when the cause turned out to be broken (cast) piston. As suggested a leak down test will confirm.

This is on my shelf now as reminder re: cast pistons no bueno for turbo engine.

If there is a lot of blow by the oil probably came out of the dipstick tube.
