Case alignment

[El_Mecanico]

After taking apart the case and thoroughly cleaned it I slid them back together and installed a couple of nuts. I noticed that the front of the engine the cases are not aligned properly...just guessing .005 of an inch off. There are no dowels in the front of the case. The question is does number 8 bearing set your line bore up?

yes

THX Craig...for a moment I thought the case was bad. Another question even though I read lots of treads on the oil squirter's are they that difficult to replace and should any reputable machine shop that doesn't work on Porsche capable of handling this task?

If you could drop and open your engine case, you should have no problem replacing the defective piston oil squirters. It took me days to decide to do it. Once a decision was made, it took less than a minute to drill the bad squirters out. The key is drilling the squirter/s out without touching the hole. Lastly, test them to make sure that they won't pop out under pressure.

See picture of the piston squirter that was drilled out from a 3.0 liter engine.

I could not have done it with confidence without the suggestions solicited from Bruce A. and Mike B., both expert engine rebuilders from the Southeast region.

THX Tony...I dropped of the case to a Porsche Mechanic...he has never replaced any but hes more of a Porsche repair mechanic not engine re-builder. Pending what he says I may do it myself. The key is a steady hand, magnify glass and guts.

I have the same apprehension before tackling the project. So I asked a few engine rebuilders (professionals) who have done this task and they all said the same thing. "Drill it out and stake it". Then I pressure tested all the squirters to make sure they don't get displaced during operation. Pressure tested them several times and was satisfied about the replacement job.

Remember one thing: the piston squirters are made of soft thin aluminum tubing material and use a drill bit slightly smaller than the hole. The drill bit would grab the squirter and spin it around inside the hole. Pull it out and your done with the removal. I think it took just a few seconds to get the squirter out.
