Looking for some input about a problem my freshly installed 2F is exhibiting.
Long story short, even when just cranking, it’s pressurizing the coolant. Normally I’m able to run an engine without a rad cap to bleed the cooling system, this one geysers coolant out if the cap is off. With the cap on it sprays out of a hose as if it’s overheating.
Something isn’t right. My first question is- is there anything else on these engines that could cause this besides cracked head, bad head gasket install, cracked block?
The block didn’t have any obvious cracks and the reputable shop that pulled the engine said it had 150psi across the board.
The head gasket is new and OEM Toyota, torqued to spec in sequence.
The head isn’t cracked, had it manafluxed when 70 thou was shaved off. The head shave is actually my main concern. I had to drill new reliefs around the head bolt holes for the alignment dowels to fit. I’m thinking either:
Let me know if you have any input!! A compression test is probably my next step, but I’d like to try the retorque+washer first before pulling the head...

- I didn’t drill deep enough (even though I measured) and the gasket couldn’t get enough squish
- (More likely), It felt like a head bolt started getting tight before it was all the way down, has anyone had trouble with the length of head bolts after shaving the head? They were making contact once torqued but maybe not enough... should I throw another washer under each head bolt, retorque, and see what happens?
