I like Fel-pro gaskets. Sometimes I use others for head gaskets, but otherwise they are my go-to brand. As this points out. The oil pump in the mouse engine (5.0 HO) that I have in my 69 van started telling me that it had a problem with it's internal pressure bypass. After high RPM runs (70 on the freeway, I have a 3.5 rear end) it would have low oil pressure afterwards. Changing the oil resolved the issue for a couple of weeks. Normally I pull an engine when I remove the pan, but taking out the seats and putting the cherry picker through the passenger door, and working it back in as an all day job by itself, so I did it engine in. I have had excellent results with their one piece gaskets, so I ordered one with the new oil pump from summit. Inside the package were 4 blue plastic things they called 'snap to its'. They threaded into the 2 front and rear bolt holes. They held the gasket in place, and when I put the pan on, they held the pan in place so I could get all the bolts started! Those things alone were worth far more than the cost of the gasket. Good job Fel-Pro!
