I have a 1975 914 that I have never seen running before. I bought it from a guy that had gotten sick of restoring it so I picked up where he left off. So finally I get it all together and put the engine in. Before I try to start the engine I undid the coil and ran the starter to try and get some oil pressure. After about 10 seconds of cranking oil starts streaming down from under the oil cooler. Its no drip, its not dumping but I think if I were to run the engine for longer than 10-15 mins the oil would be all on the floor. I have replaced the oil cooler o-rings and made sure the mating surfaces were spotless on the cooler and the engine block. I have pulled the oil cooler out completely and put compressed air through it in a bucket of water and it doesn't look like there's a leak. I am at a loss. What in the world is my problem, and how can I fix it?



Also Thanks a million to those of you in this forum all your posts have helped me restore this thing immensely!

Pressure sensor on top of the back side of the engine!?

+1 ......... that was what happend to mine, during break in on the engine run stand.

Are you talking about this?

Yep . Happened to me last year . Use some plumbing thread sealer on it .

Except what happens is the sender splits at the seam and leaks!

Me also as well... my clue was oil on the bottom of lines that ran over the sender and on the bottom of the air cleaner. Installed new sender and rubber boot and no more oil... at least not from there
