I just went through the re-install of my
oil pan and used the blue RTV Sealant. I am also using a windage tray and two
oil pan gaskets. I sealed the first gasket to my
oil pan with the blue permatex and then the second gasket to my windage tray. Then I put a skim coat on widage tray gasket that mates to the block & bolted it up loose for about an hour so the tray would stay stuck to the block while I was putting on the oil pan. After, I removed the bolts from the windage tray and it held to the block, then I applied a skim coat of blue RTV to the top of my oil pan gasket that will mate with the windage tray and bloted everything back up.
My engine is still in my car which makes this more difficult than if it was out. I was waiting until tonight to refill my oil ( letting everything set up, RTV). I believe the blue permatex is #3 blue. Is that a bad choice?
