Exhaust presure in oil chamber
After a engine rebuild, when getting turbo boost i get a exhaust presure in the oil pan. And the oil check pin hops out and oil flushes out og the hole.
When opening the oil filler cap and reving the engine so that i get boost presure, exhaust comes out of the oil filler hole. Ive looked over the vacume hoses and cant find a problem. What i want to now is wich hoses/cables might have exhaust pressure. And maybe some one have pictures of rebuilding there engine. So that i can look at all hoses and so on. The car goes terebily, when accelerating and getting boost there comes blue smoke out of the exhaust pipe. The car is a 92 FD RX7 Japan spec. Folowing mods Greedy air intake. Greedy front mount intercooler Greedy Dump valve. I hope someone can help. Here's a vacume chart. Any sugestions? http://www.apneablue.com/rx7/photos/...colorhoses.jpg JT Pedersen |
exhaust pressure? the only thing i know of is getting compression to the oil by bad side seals. you should also have fuel in your gas. not sure how you would pressurize the oil with exhaust.

Ok alittel uppdate. It's boost presure. Every time the turbos kick in, i get presure in the oil.
Maybe this clarifyes it. JT Pedersen |
bad side seals. the compression is pushing past the side seals and pressurizing the oil chamber. rebuild is the only fix.
|
hmm, the engine is just rebuilt, vell not replaced apex and side seals, but they where in perfect order.
How sure are u? |
Oh and another thing. the problem only occures when i get turbo boost. like above 3000 rpm.
|
well i'm not dead positive but that is the only place i see the possibility of pressurizing the oil. by all means get other opinions and not just go on mine.
|
Thanks for your imput. Im realy afraid of an answer like that again. The strain of stripping the motor again is not good.
Im hoping for it to be the turbo's but time will tell. JT |
Could also be a bad corner seal, happened to my best friends car, cracked corner seals
