Because the previous conversation regarding this oil pan gasket was started in the middle of another thread or posts, I am making a new thread specific to this gasket. This thread is a continuation of that older thread. Here’s the link to that previous thread. PARTS - Oil pan gasket and throw out brg (y-blocksforever.com) FORD DEARBORN (Jeff) sent to me one of the new silicone oil pan gaskets made specifically for the Ford Y. This gasket is being manufactured by Real Gaskets Tennessee (RGT) and is new to the market. I initially trial fitted it to a Y block oil pan and it was a perfect match to the holes. The gasket also has plenty of material around the rear seal retainer area which is a plus as that tends to be a problem area when it comes to oil leakage. Next was to actually install the new RGT gasket on an engine. The engine selected for this is the 312 dyno mule which had been recently loaned out and was in a ’32 Ford making a couple of trips across the country. Those trips put over 12,000 miles on the engine and prior to that, it had over 1050 dyno pulls on it. The next issue of the Y-Block Magazine (#173) will have an article about that particular road trip with the dyno mule. Upon receiving the engine back, it had some road grime on it but absolutely no oil leaks from the oil pan gasket or rear main seal area. The oil pan gasket on the engine for those cross-country trips was the Best Gasket brand (black) with a rubberized compound combined with the fibrous material. For the ’32 Ford, the oil pan had been switched from a factory baffled front sump oil pan to the HD Truck 7qt oil pan which was also factory baffled. The Best Gasket oil pan gasket had been previously installed with white lithium grease on both sides for sealing purposes which facilitated its removal for this new test. For the RGT oil pan gasket test, the HD pan would be retained. With the dyno mule on an engine stand and upside down, the new gasket is laid in place on the pan rail of the block. The rear main seal retainer does have the factory studs in it and that eliminates another potential oil leak that can occur on the Ford Y. If the studs are missing and replaced with bolts similar to the remainder of the bolts being used to attach the oil pan to the engine, then oil can seep past those threads in the oil seal retainer and make it appear that the rear main seal is the source of the leak. The new RGT oil pan gasket is a perfect fit on the block and the oil pan is subsequently laid on top of the gasket. This is where the instructions supplied with the gasket comes into play. And the instructions are very good and specific. Absolutely no sealer of any kind is to be used and the bolt torque should be limited to 20-25 in-lbs. While I had four different in-lb torque wrenches on hand, I had only one that would go down low enough to match the required torque value. With the oil pan properly tightened, the inlet oil tube gland nut and oil pan tube retaining nut were appropriately tightened. At this point the engine is mounted to a dyno cart with seven quarts of oil and a new filter being installed. As soon as the schedule permits it, the engine will be mounted to the dyno and run. With some header and intake manifold testing that needs to be performed, this will be a good opportunity to also test the RGT oil pan gasket and check for any potential oil leaks from that area. I expect to have a dyno opening mid-February for the dyno mule so more word on that when it occurs.
