Agree absolutly and this shows a good REASON that when comparing any oil/drian interval/oil quality issues THAT if you show pictures or have compression prssure reading that they must be about SIMILAR engines run in SIMILAR situations otherwise all data is OFF and not valid.quote:

In some engines, the valve cover is not bathed in a constant flow of oil like the rest of the valvetrain. So the moving parts are kept nice and clean by the detergents in the oil while any crud deposited on the valve cover by blow-by gasses stay there permanently. You'll see this in any part of the engine that has little to no oil flow over it. Perfectly normal.
Unbelievable. That engine is PRISTINE!!!quote:

That question is a bit off topic, but yes, it is a DOHC engine, not a pushrod. If you're confused on how this works, I suggest you do a search or post elsewhere.quote:

For that Toyota engine, are the cam lobes directly operating the valves?
I'm confused as to why you think this operates differently then the other poster. Maybe you are the one who needs to do a search.quote:
