Hi TurboEnginerd,

Glad you found this DIY useful.

I think Loctite instant gasket is an excellent choice too.

FYI, Roofing Caulk can handle the scorching sun on your house roof, so it can handle engine heat. The typical engine block temp is about 100C or so (give or take).
The roofing caulk I have had now for 8 months are rock solid, bone dry. Plus the roofing caulk is locked in place in the black RTV gasket maker.

I can tell you that this DIY helped me alot: it works, it is a simple fix and 8 months later, the car is bone-dry = priceless (I hate oil stain on driveway!).
