Rear Main Seal, AGAIN??
I'm dealing with a 58, 392 Rear Main Seal leak, STILL
I have replace it twice, and still leaking. My first question, why do the 354, and 392 have different seal numbers, and what is the difference, other than what is obvious to the naked eye? The 354 rubber, has no shims, 392 has shims. However, the rope seal is same for 354 and 392.
The 426 rubber, looks like much thicker shims than the 392?
Part numbers, Best Gasket;
354 rubber, 3880 E
354 rope 5263
392 rubber 3A07
392 rope 5263 (same as 354)
426 rubber 3879 E
No listing for 426 rope
Have been told possible that leak could be because not enough ventalation? All I have is the oil filler breather in the valley pan.
This leak is driving me to drinking, like I really need a reason.
