Just thinking about it, this knocking sound came on very suddenly.

There was no build up to a knocking noise, its not getting any louder, its has been like this now for about 3 weeks. So, that doesn't sound like bottom-end to me, just this was my fear.

And it has had some good pastings in that time.

The only way you can do this with the engine in the car on an Omega is by dropping the subframe but you will need to support the engine somehow - using an engine bridge.
 ......
If you drop the small sump the big end on the conrods are quite easliy accessable.

If it came on suddenly then check your oil pressure - should be 1.8 bar @ idle and 5 bar max - you check it from the oil pressure switch - if you are stuck for a gauge I could post mine to you - you pay postage of course

Theres a relief valve and an oil pressure regulator valve in the oil pump - these (with a huge bar) can be removed / replaced - but you need to check pressure first

they were but we were allowed to interchange one bearing cap per cam in the factory

yes that was quite worrying, guess that being loose has mullered the bearing?


So if the bearing is mullered could it be changed from another car, only heard  rumour they are built specific for each Head etc, any truth.

Sorry to drag this one back up, but this obviously isn't going away on its own, and I'm not going to do the womanly thing of turnign the radio up to hide the noise.

I want to get this resolved before it gets serious.

Geff, what gauge/connector/fitting would I need, would a local garage have this tool? just thinking maybe I can slip them beer tokens....

If not, then how much you reckon for postage?

If the cam(s) are walking, what is likley to be damaged, and what is simplist (and cheapest) way of fixing this?
Is there a check I can do see if the noise is top or bottom end/ Dont want to spend money sorting the cams if this isnt the problem. Roughly how much am I looking for it if its the bottom end?

Sorry lots of questions, have had no time recently to look at it or even think about it.

Thanks.
