stock guage is at like 1/4 and before the temp in megatune gets to 190 its blowing boiling coolant into the overflow. If I cant get my hands on a leakdown tester by the afternoon then I’m just going to buy a new headgasket and replace it. The head and block should be fine. I had some machine work done to the bottom end and had the head surfaced and cleaned all by BRK, so if there was a problem I think they would have caught it. anyone have a leakdown tester I could borrow? --- _[View the full topic](https://forums.speedlife.net/t/coolant-building-too-much-pressure/31555)._
