Yeah, I could’ve come up with that…thanks

[Jeff]

So then are there any helpful tip or tricks or links that you know of to help guide me through pulling the head? I searched through all the videos on here and didn’t find anything.

I know I still need to at the very least do a compression test. Unfortunately I don’t have easy access to compressed air for a leak down test without towing the car somewhere. What else could cause the cooling system to over pressurize like it does other than a head gasket or crack? Let’s just assume for the sake of conversation that it’s leaking into the cooling, would a leak down test be able to differentiate between and tell me whether it’s a head gasket or a crack? Or just that it’s one of the two?

Considering my cooking system is over pressurizing, it’s pretty safe to say that I’ve got a leak into the cooling system, right? Granted I haven’t done a compression test yet, so I don’t know which cylinder yet. But there’s also no sign of coolant in the oil. But if I had a cracked head, wouldn’t it be leaking fluid on the outside? Or is it possible to crack internally? I just watched Eric the car guys video on a leak down test and he said, ultimately I could just hook compressed air to the cylinder and listen for a leak. Safe to assume it’ll be leaking into the cooling system. If that’s the case, would a leak down test be able tell me if its a gasket or a crack?
I know I hadn’t had the car long but I never did notice it smoke or use oil.

Thanks for the helpful links! I’ll borrow our compression gage from work tomorrow. In what range should the compression be?

[Jeff]

What will a combustion gas leak test tell me and what if a guy doesn’t have one of those?
