It's a very sad day for me and my Porsche.. something is very, very wrong.
The engine is running poorly, it's smoking, and it's making a strange flapping noise.. I talked about this a few weeks ago. We've since determined that there's a 'leak' between the cylinder and the cylinder head that's spitting oil and compressed air. The fact that there's compression leads me to believe that the connecting rod is still good. I'm stumped and I'm frustrated, so I need some help: What could be the problem? What can I do to help pinpoint what's happening? The fact that there's compression leads me to believe that the connecting rod is okay. Is the cylinder head warped? The cylinder? Grr.. I just put money into engine work and a week later this happens.. the pessimist side of me wants to say that the two are connected, but it's probably just the standard mechanical failure that happens to 30 year old cars. So what do I do next? What are my options? The car's in SD and I'm in the Bay Area working fulltime and doing summer school.. which means I'll have plenty of time to research things but little time to actually work on the car. All for now, thanks in advance for the help, I'll keep posting as I discover new things. Feel free to ask questions of clarification and such. Edit: Forgot to mention, it's the #1 cylinder. -Tyler |

Yes, I did forget many details.. was very tired last night.
So the car is a '72 1.7 with fuel injection. I believe that a dropped valve seat, blown head gasket, or broken ring are all within the realm of possibility. I have not done a compression test on the engine yet, but the #1 cylinder is ejecting compressed air which I believe is a good sign. As for engine work, I don't have the complete list on hand but it consisted of replacing many oil seals (not all of them, but many.. I have the list at home), a new oil cooler, clutch assembly replacement, MPS replacement, new FI hose, and other minor things. Yes, the car does smoke and is leaking a ton of oil. |
