Appreciate any advice on which oil pan gasket works best for my 302 that I plan on resealing soon after many years
Used the fel-pro one piece on it the last time and leaked at front cover slightly using correct gasket
While I can not speak to exact part numbers, A Friend just had Cope Bros. Build out a 302 motor and He had a "blue" single pc pan gasket fail immediately and it was removed and a traditional 4pc gasket installed and successfully Dyno (leak) tested.
Thanks for the reply.. the fel-pro is blue so I assume that is the one the they used, leaning toward using the traditional one that didn't leak before
Depends a lot on your oil pan. There are 2 different front seal requirements on the pan gaskets. Problem is made worse when you try to use a later "correct" GM service replacement pan. GM started sending out the new "thick" gasket service oil pans for EVERYTHING regardless of original year of the application. A service GM produced '69 302 pan sold after the change in the mid 70's would leak badly with a '69 "correct" gasket. You would need the '75 and newer thick front seal pan gasket in that situation. Originally, GM would send a new style gasket along with the revised pans but that was a LONG time ago.
Try the thicker front seal pan gasket spec'd for a '75 drivers side dipstick engine.
Yes ..I will measure the pan once I get it off and make sure I had the correct gasket for the depth measurement at front
