While changing engine oil recently, my workshop informed me that my valve cover was leaking oil and needed fixing. So a replacement part was duly procured and I took the opportunity to look at the insides of my 1NZ-FE engine:

The cause of the oil leak. A perished rubber seal was the culprit. All these were meant to be one single rubber part.

All shiny and slick. The oil is dark because its 10,000km old.

Timing chain and VVTi mechanism. Chain looks ok.

Looking down into the valves

The new rubber seal is back into the valve cover.

And all this is done on bargain-basement priced C engine oil, serviced every 10,000km, typically driven in stop-go traffic, occasional visits to redline.

How much did it cost you to change the valve cover seal (parts + labor)?

I too had the manifold gasked replaced twice on my 6yr old 130k km optra.
I was surprised why it leak so often n e mech said its a common problem wh c oil. I dunno how true this is though.

My previous corona also used c but never had this problem.

I think its more design n parts quality issue.

Manifold gasket would never touch engine oil, right?

Mine is the valve cover rubber seal. I suppose some types of engines use metallic/paper gaskets for a good seal between valve cover and block instead. I assumed mine was a paper gasket until the valve cover came off. I'm surprised rubber lasted so long against the heat of the engine.....

What type of engine oil did you usually used? do you stick to 1 brand or try out a lot of brand?

That part of e engine is sprayed wh oil as e camshaft spins n oil is splashing around in there. U try to open e oil filler cap when engine is running then u know.

Early engines used cork gaskets but now i see all r rubber. Maybe its silicon rubber so oil dun affect it.

Valve cover only la. No need to what torque specs. It's the valve head that needs it when you change head gasket.

Oh ok. To me, manifold gasket refers to the exhaust or intake manifold gasket. Which shouldn't come in contact with oil.

One of the workshops in AMK Autopoint. Honestly they had put the cover back on quite quickly so I can't be sure if they done it in the right sequence and torque or not. I guess I'll find out if my engine bay continues to be oily. But they've been a very good workshop to me and I assume they will put things right if something went wrong.
