Omega General Help / MV6 engine swap

« on: 13 October 2009, 18:06:27 »

I am about to replace the engine in my MV6 for another unit as mine has had it, any advice would be appreciated. It is a manual and I was going to try and leave the AC system un-touched by removing AC pump and leaving it in position when I remove the engine if this can be done.
Any advice would help.
Thanks Craig

Omega General Help / Difference between MV6 and Elite Engines

« on: 12 October 2009, 12:44:07 »

Can anyone let me know the difference between the MV6 engine and a 3,0L Elite? As I understand it is the Cams and I might have got one to go in my MV6? But need to know what I need to change.
Thanks

It coming from rear/top of engine and varies with revs of engine. I will check the manifolds tonight and see if I can see anything obvious.

Have changed oil and filter twice and have got a complete set of 24 tappets and fitted them but still making the top end noise. I am now having to look at another engine as I am just throwing too much money at this engine.
Has anyone got any recommendation as to getting a replacement MV6 engine?
Thanks

Thanks for the advice, I had flushed the engine before I fitted the tappets I thought were suspect, and then changed the oil, The engine is very loud so I assumed it was somethine worse than a sticking tappet. so can I assume it should be ok to drive it and keep changing the oil and filter to see if it cures the problem? and can they be quite loud?
I drained the oil through a fine filter to check there wasn't any swarf or metal in it and it seamed to be clean as was sure it was a top end issue.

Omega General Help / MV6 Engine Problems

« on: 21 September 2009, 06:45:46 »

I hope someone can help with this problem, I have a 1998 Omega MV6 that I have had for 2 year and has ran like a dream (120,000 miles). About 3 months ago it started to make a chattering noise from the top end, this would happen once in a while and after it cooled down would be fine again for several days. This got more frequent and now is constant, I assumed it was a tappet, there is also some cream in the rocker filler. I have changed the timing belt as I was unsure about the tensioners, and removed the cams to check the tappets, as there are 24 I only changed 6 that seamed to have weak springs.
The engine still has the lound noise from the top end but slighty different now that seams to be the rear of the r/h head, I now suspect it could be a head gasket/ valve gone. I have tried to get a second hand engine off ebay but as they seam to go for about £400+ and I can't hear any running I would rather fix mine if possible. I was going to remove the rh head next and change all the tappets.
Any ideas or advice would be great.
Craig
