He's not reporting an overheat condition.

Thanks for the post, though.

No overheat issue. I don't like issues that are hard to peg down. Head is most likely the culprit.

Might want to take care of that ASAP before further damage is done.

Update. Head is the culprit. Was over pressurizing the cooling system at cool temps. Once warm the crack would swell and seal. New head time.

Are you sure it's not your pressure tester bleeding down because as stated above, coolant is going somewhere otherwise.

Head was magnafluxed today. Machine shop found no cracks however head was warped. I ordered a new aftermarket head, not wanting to risk machining this one and have it crack. Should be good to go soon.
