Oiwa Garage Tech Note
"If oil is getting into the cap, replace this and check the distributor O-rings at the same time - oil inside the cap is a classic Acty misfire cause."
Frequently Asked Questions
Why does oil get inside my distributor?
A failed internal seal lets engine oil migrate in and foul the contacts; this cover addresses that path. Check the O-rings too.
How do I know oil is getting into my distributor?
Pull the cap and look for oil pooled inside or fouling the rotor and contacts. Oil in the cap is a classic Acty misfire cause and means the internal seal is letting engine oil through.
Should I do the distributor O-rings too?
Yes. If oil is getting into the cap, renew the distributor O-rings with this cover so you seal every path oil can take.
