Sorry for sending you down the wrong path....didn,t notice engine was 2.6...doddgy eyes

Does sound like lifter noise though from the video clip...maybe they have drained down and just need time to refill

[omega3000]

Thanks guys.
Plugs all checked and refitted without any problem.
Left it running earlier for maybe ten minutes but no more, and haven't driven it yet. Temp had started to rise so hopefully stat is working.
I'm hoping that any problem with stat or transfer pipe would result in a coolant leak somewhere. So far there is not. Everything else has been redone - inlets and camcovers - but still nothing seemed out of place.
Maybe I'll take it for a run tomorrow evening and see what happens. Scared of it going 'bang' though 

I wouldn't do that if it was mine , if no oil is getting to the lifters . Seem to recall webby's car sounded similar after he did some work on ralf but we never heard if he found the source

Not keen on taking it out either  :-

Thought it might be necessary though?

In my earlier post I mentioned "hydraulic valve adjustment mechanism"  I dont know what this is but I seems to me that you are not getting oil to the lifters .In doing the cam covers have you blocked an oil way with sealant

Don't know what that means either, and only used sealant as prescribed?
Could oil ways be blocked somehow?

There are feed pipes in the area, its possible to block them. If you used sealant as per the guide, can't see how it would happen. But it looks like you may need to take covers off to inspect, if just for peace of mind 

[jonny2112]

I had the covers off and replaced again as per the guide. Nothing trapped or blocked afaik but where could potential problem areas be?

[robson]

I seem to remember an earlier post on cam covers that said that there was an oil feed on one corner near the half moons

[Andy H]

Oil feed is via drillings through the block and cylinder heads straight to the underside of the cam bearings. The only way to block these feeds is to fit cylinder head gaskets back to front (it has been done......).

There are only three oil pipes as such on the V6, one in the sump from the oil strainer to the oil pump and the two from behind the oil filter up to the oil cooler.

[albitz]

So,where does the oil come up to feed the cams ? Its not just the bearings which recieve oil,the whole area inside the cam covers swims in oil when the engine is running,to keep the lobes lubed.Thats the critical thing for Jonny.If it is near the half moons as Robson suggested then close inspection around there seems like the next thing to do.
I must say I feel really sorry for the bloke.Its obvious by the length of the thread that we are all trying our best to help,but due to his location its not a matter of someone knowledgeable going and having a look at it for him.Must be very frustrating indeed.
Then again,he doesnt have to live among all you English people.

Sure one of us would have been over if he had been in the UK 

I've done V6 cam covers, what I don't understand is how the tappets could have drained (if they have done that is)

He is in the UKTunnie.Hes not in GB though.
I agree though.If he was on the mainland,chances are someone not too far away,with plenty of knowledge would have offered to go and cast an eye/ear over it for him.Also agree that dry lifters doesnt add up with doing camcover gaskets,and it would be a hell of a coincidence.
Having said that,istr TB had a big problem with dry lifters or similar after he and other OOFers fitting LPG to the rusty bullet.

[albitz]

Listening to the sountrack several more times,my uneducated conclusion would be,no oil up around the cams or dried out lifters.
Run it again briefly,then whip off a cover and look for signs of oil or lack of it around cams ?
If no signs of oil,find out why ?

Sorry yes i meant GB

Sorry yes i meant GB 

I forgive you
