Oiwa Garage Tech Note
"Exhaust studs seize - soak them first and be ready for a broken one. Clean the faces and torque evenly so the new gasket seals against the hot side."
Frequently Asked Questions
How do I know the exhaust manifold gasket is leaking?
Listen for a ticking that grows with revs at the manifold joint and look for soot tracks at the gasket. A cold-start tick that quiets as it warms is the classic manifold leak.
Any tips for the exhaust studs?
Soak the studs in penetrating oil first and be ready for a broken one - seized exhaust studs are common. Clean the faces before fitting the gasket.
Should I replace the whole set at once?
Yes - do every manifold joint while it is apart; one old gasket left in place will leak and tick until you go back in.
