My RX-7 w/Nissan engine has developed a nasty, voluminous leak in what I have determined is coming from the oilpan gasketure. Actually, this engine has two oilpan-looking things, a smaller bottom, and a larger, intermediate pan. Here are some pics.
First small pan off
Small pan with proposed gray RTV
In this next shot, you can clearly see where gray RTV is used as a gasket between what I call the intermediate oilpan and the engine
In taking off the small pan, it shows that RTV or equivalent is the factory method of sealing. My question is, would cutting out a pattern in gasket material and using it instead of RTV work better? Combination gasket material & RTV? Other?
Also, noticed an interesting thing when the small pan came off:
Yup, the oil scavenge was broken clear off. What could have caused it to snap?
The intermediate pan is 3x longer and will come off tomorrow. Any sealing ideas would be much appreciated.
