Here's the short story:
I recently bought a 91 with a 4k complete rebuild. The previous owner kept meticulus records of everthing and I have receipts of a purchased and work orders for an installed HKS 1.2mm MHG.
I get the car and turn the boost up to 16psi and the HG blows on my first hard run. White smoke bellowing out the back because a heater hose blew off when the HG went.
This happened about 2.5 miles from my house. I babied it home (coasted downhill most of the way) and parked it in my garage. I'm pretty sure I lost most of the coolant in the block; but, the temp never went above normal. Another thing is that the Radiator was still full along with the overflow.
I pull the head and find that #2 and #6 are badly blown and #3 was barely blown. Why might you ask? Because it was an OEM gasket and NOT the HKS MHG that the shop claimed they installed on the work orders and receipts. So, the previous owner got ripped off and I'm paying for it!
Ok. So here's the questions.
What are these "bubbles" in the head?
What caused it...could it have been any of the above described or already there when the shop installed it?
Is the head useable?
I included pics and refer to my sig about mods.
Thanks guys!!
