My Omega is a 1994 3.0L V6 Elite/auto.
I am in the process of changing cam cover gaskets - the passenger side leaks, drivers side fine.
At the same time I have replaced O rings, as a few were missing or worn/brittle, and replaced inlet gaskets.
Cleaned out breathers, and will do some more bits over the next few days.
The EGR to plenum had no gasket , and had an air leak.
Also I am still investigating tapping noises, which were thought to be hydraulic lifters.

Now, the strange thing I found was that of the three drivers side inlet ports, the centre one was absolutely spotlessly clean compared to all the other inlet ports, as were the valves. Why would one port be so clean ?? So clean that it looks as it would when new !   :-?

My wild guess, has this port had new valves fitted ??
Or is there some other reason for this strange find ??  :-/

Anyone have any ideas, or seen anything like this before ??

Since I bought the car in April, it has driven perfectly, and performed well,  apart from the tappety noise which is more obvious when cold, and eventually quietens down when warmed up, or driving at above 30mph.

Thanks in advance for any comments, or advice...

Noisy tappets is common especially on older engines, a few short oil changes (500-1000 miles) may clean them out abit or if you can be bothered it's heads off and squeeze the dirty oil out in a vice (bit of an effort :-/)

Or like me just wait for the engine to warm up then it goes

Any signs of lumpy running on start-up? It could be that the injector is leaking fuel when engine is stopped, this would have cleaned the port and valves.
On start-up the excess fuel causes a misfire and lumpy running until it is purged.

Thats interesting...

No lumpy running on start-up. It did have a fast idle , which I found to be an air leak at EGR to plenum, where there was no gasket !!
At the moment I have the inlet and injector assembly off the car, so I shall clean it up and check the injectors.
Two of the injectors are very clean, at the spray head, the others look as you would expect them to.

Just hope that after all this stripping engine down that there are no more leaks, etc..lol

Thanks
