I know its been on here before By other members I am hitting a brick wall at 3750 rpm .

Firstly this does not happen when car is cold only when full operating temp is reached 85-90 on the temp guage .

I have even had the car on the drive warming up and freely reving past 3750 but once fully warmed up symptom is their .

This bit of the original post rings a bell. My previous car (Merc C200) ran a treat when cold but when up to temp. it was almost undrivable due to sporadic weak mixture. It obviously was due to the engine being 'on choke' only the injection version, when it was running ok.  I checked throttle body, lambda sensor, water & air temp. sensors, with no result. Decided in the end it must be corrupted information in the EMU and PXed it for the Omega before spending any more money on it.
Mind you, if the Merc. forum had been as good as this one I might have got it fixed  ;D.

Theres a word of warning in there Kes, If you take it to Vx, they WILL change your ECU, and then start looking for the actual fault

Ok I checked my ramvalve today . Hope this is understandable .

I took off the ramstack to check the valve or what appears to be a flat piece of metal and checked it could be turned fully open by hand , it could with no tight spots . The black plastiv thingy attatched to a spring which turns the valve can be pushed by hand fully to the stop . When it is cutting in and out  at 3400 the spring is fully open to the stop,sio I assume the valves would be fully open .

I noticed with my ears today but this could be normal , the black thing thats goes across the top of the inlet manifold with the pipes in sounds like its sucking air for england .

Asked my mate if he had this problem afore I had it off him he said no . The cambelt was changed just before I got it so dunno if their has been an assembly problem .

 :-/ what to do next methinks at minimal cost .  :)

Hi all

Dunno if I have found something that might be or assisting the brickwall.

I was giving the enginebay a bit of tlc today and noticed a light film of creamy deposit on one side of the oil filler kneck and a tiny bit on cap . Also in a few places same film was on the upper inside (obviously) of the expansion tank . I do use coolant no deposits on dipstick or brown deposits in the coolant.
I only average 25 mile a day in two 12.5 journeys.

Also took the plugleads off one side (nearside) and everyone had oil on them dunno on the offside yet . I very much presume this is  cam cover seals .

What a muppet I've just noticed their are 2 multirams  :-[ oh well back to the bay then .

The oil in plug wells will likely cause a misfire, but may have also damaged plug leads (they don't take kindly to being submerged in hot oil).

Mayo in filler cap is the 12m short journeys I reckon....

Cheers for that .

So I've read somewhere that you can a cam cover kit for approx £60. Whats in it other than 4 gaskets as I can see you can get the gaskets off fleabay for about £9 a side.

I am not to sloppy with spanners is it a difficult job as I've never worked on a V6 before .

I assume the other multiram is at the rear of the inlet manifold and would have to remove the manifold to check said ram which would appear to be half the gasket changing job .

Lasltly where abouts would I find the crank breather .

May be some time afore I can do the job to find that thing we are all short the bloody time , so if I was to go to an independant dealer what sort of remortgage do you think I ma facing .  :'(

We have a maintenance guide on camcovers......the gaskets on ebay are dodgy although we have found a better source from here:
