Oiwa Garage Tech Note
"Check the head and block for flatness before assembly and torque the head bolts in the correct sequence and stages. A fresh gasket on a warped head will not hold."
Frequently Asked Questions
Should I replace the head bolts too?
Inspect the bolts and follow the correct torque sequence. If in doubt about stretch, plan to renew them.
How do I know the head is flat?
Check it with a straightedge and feeler gauge; a warped head must be machined flat before the new gasket will seal.
How do I check for a blown head gasket?
Look for white sweet-smelling smoke, coolant loss with no external leak, a mayo-like mix under the oil cap, or bubbles in the coolant. A compression or leak-down test confirms it.
