Oiwa Garage Tech Note
"Do these with the valve cover gasket - a fresh gasket still weeps if the bolt seals are hard. Snug the bolts evenly, do not crank them down."
Frequently Asked Questions
Should I do these with the cover gasket?
Yes. The bolt seals and the cover gasket work together, so replace them in the same job.
How do I know the cover bolt seals are leaking?
Look for oil seeping around the valve-cover bolt heads even after a fresh cover gasket. Hard, shiny bolt grommets let oil weep past the fasteners.
Should I replace this if it is not leaking yet?
If you already have the area apart for other work, fit a fresh one while the labor is done. Otherwise replace it once it weeps.
