anyone ever tried Blue Devil Headgasket repair? I know it's just a bandaid but hell it's better then trading it in looking like it is now? Guy at the place said it's garennnteeeed but it's 60 bucks a bottle. I filled it up and bleed it as good as I could and it's not dropping or overheating but still fluctuating as much and we've got heat but it's still coming and going.

 

3400 or 3800, nothing is gonan fix it except pulling the inatke and heads.

I've seen some nasty motors, really the worst I've ever seen in 30 years of playing with cars that were newer GM's with bad inatke seals.

Green gooey sludge almost filled the whole lifter galley!
