I have an oil leak on my '76 that seems to not follow usual patterns. The leak only occurrs when the car is warming up. It doesn't leak when it's just sitting and it doesn't leak near as bad (almost not at all) once the car warms up. It drips off the oil filter, but I can see the oil dripping from the oil cooler above, onto the filter. At it's worst, it drips about a drop a second. I suspect the oil cooler seals, but, wouldn't that leak all the time, not just at warm-up? And it certainly seems like the drip wouldn't slow down when the car is warmed up if it was the cooler seals. I also kept an eye on the oil pressure sensor and didn't see any oil leaking in that area. (IMG:style_emoticons/default/confused24.gif)
Thanks in advance for your thoughts, Tom |

I was looking in the 914 tech manual, and on page 210 of the engine section it describes what I believe is my problem. It says, "If the pressure relief valve is stuck in the upper end of it's cylinder, cold, thick oil may cause a leak in the oil cooler."
That would explain why my car doesn't leak when it is just sitting and also doesn't leak when it is warmed up. Anyone know anything about the "oil pressure relief valve" and how to check/repair them? (IMG:style_emoticons/default/confused24.gif) |
