Oil in spark plug tubes

I had oil in the spark plug tubes of my '89 SV21, and I hear it happens often with all engines designed this way. I researched it and had a go at fixing it. I read a lot of posts describing the procedure but there were very few actual photos. So here are some I took. Hope they you if you are attempting this job on their own. It's not too hard.

A 30mm socket is required to remove the four nuts holding the rocker cover on. Vice grips worked unscrewing the tubes.

You want to clean the thread and re-seal the bottom of the tubes with a high temp sealant, and replace the seals at the top of the tubes. A set of these was $25 at Repco.

Kind regards, rubber.

The spark plugs are seated deeply withing the tubes that DJKOR speak of. if it's leaking in through there then it's not a big fix.

If however, it's your valve seals, then the head has to come off and the valve seals replaced. That's a bigger job.


I went to change my spark plugs and when I removed them they came out drenched in oil.Its a 1989 camry 2,0 litre.

Could the seals on the top of the rocker cover be leaking.

Is it a big job to fix.

Thanks :o
