Engine Mechanical problem
1988 Mazda b2200 4 cyl Two Wheel Drive 200000 miles

I rebuilt most of my engine and had everything milled professionally but puting it back together I used the old head bolts.

After 25k miles of running great my cooling sytem started to pressurize and the heater blew cold air momentarily.

I think the head gasket started to leak pressure into my cooling system causing it to overflow cold coolant as it warmed up and a lot of steam came out my exaust that smelled like anti-freeze.

I believe the head bolts became stressed, so I replaced them with brand new ones along with all the gaskets involved and torqueing everything properly.

It ran perfect before it started to do the same thing three days later.

My cooling system keeps blowning coolant out as it warms up then looses more as I drive it.

Could this be because the head became warped even though the engine never overheated?

I can't find the paperwork that tells how much was milled off but I think it was straight before they did it so it was just to resurface the head.

And for removal/instalation, those are the same bolt patterns and ft/lbs that I used.

I will probably take the head to be tested. I found a mach. shop I trust that will check straightness for free.

I just might have to pick one up at a salvage yard if mine has already been taken to the service limit

I just wanted to make sure I'm not taking the head back for no reason.

If there is anything else it might be please let me know.

Would check all water jacket passageways to see there is a blockage
