Omega General Help / Re: Clunk from front suspension

« on: 26 June 2022, 14:39:11 »

Everything was replaced about a 2 years ago. Have checked on a 4 post lift and nothing is broken. Have checked all bolts and re torqued all of them. Drop links look ok. Is it normal to have the gap under the front strut top hat?

Omega General Help / Clunk from front suspension

« on: 26 June 2022, 14:26:25 »

I have had a issue with a rattle from the front of my MV6 when driving on rough roads. It would stop when I touched the brakes. I changed the caliper slide pins that have stopped the rattle. But if I hit a pot hole/drain cover I get a clunk from the front. Should there be a gap below the front strut mount top hat in the engine bay? it is about 5mm. It had Bilstein struts & eibach springs fitted.

I’m trying to get another manual gearstick for my 3.0L V6 as the rubber collar to lift for reverse has broken if anyone has one for sale?

Yes the 90499289. Last set were genuine and last years. Had gearbox off for new clutch and had problems ever since with cheap gaskets. Have cleaned all faces up ready for refit. Just need some decent gaskets. I assume they are just a ring, and don’t go over the 2 studs?

Omega General Help / V6 exhaust to manifold gaskets

« on: 18 March 2022, 19:39:54 »

Does anyone know where I can get some genuine 3.0L V6 manifold to exhaust gaskets? Had ordered some from vauxparts only to be told they were out of stock after 3 weeks. Have changed twice in 18 months with cheap eBay parts that don’t last.

Omega General Help / 3.0l MV6 exhaust blowing

« on: 07 March 2022, 19:52:25 »

I have had to change the gasket on my 1999 3.0L MV6 down to about 3 in the last 2 years. I assume it is because I have used the cheap ones off eBay, they just break up each time.
I’ve brought some genuine VX ones so hopefully will sort it this time, just want to ask is it just the gasket, or should I also use a joint paste? Or any other tips?

Have ordered the parts, no oil spark plug wells, so hopefully the parts will sort it. For info, tried again this morning when cold ran fine, drove about 1/2 mile when it warmed up went onto 5 cylinders again!!!

Thanks, will swap the knock sensor. The engine has just been put back in, had issues with plug leads, have a space coil pack so might change and see. Will check plugs for oil.

Finally have driven my 3.0 V6. Ran ok at first then seamed to be on 5 cylinders. Have done paper clip test and have code 16 (knock sensor) but seam to be getting 12, but no code for that. Any ideas? Will try changing knock sensor.

Thanks for the advice, the car had wheels off most the time it was stood. will try the prop bearings and new rubber bushes and pump the tyres up to 50 psi and see.

Also the problem seams to be coming from the rear/Diff which makes me think it could be the prop bearing

Wheels have gone back on same corners and was going to take off and check. it drives fine below 20mph then starts. Had no problems with clutch that I noticed on when I pit it back together. and it seam ok when you start it on axle stands.
I have ordered some new rubbers and centre bearing for the propshaft as that seamed an obviously easy fix. I can't drive any distance as not mot'd and the vibration.

Omega General Help / MV6 3.0L rebuild issues

« on: 29 July 2020, 14:13:41 »

Don't know if anyone can help with this one but I'm about to give up with my 3.0L MV6 Manual. it has been off the road for over a year have done a load of work on it, all new brakes, shocks changed engine etc. about 4 months ago thought I had finished it. I did about 10 miles in it and it drove great, then spotted the rear crank main seal was leaking.
so removed the engine & box and changed the bearing. all seamed ok. drove it again no leak, but now a horrible vibration above 20mph, like you are driving with a rear flat tyre!!! have looked it over can't see any obvious problem. Am going to change the prop rubbers, there is a little backlash in the diff but not excessive. as it drove ok before am baffled, wondered if anyone had a similar problem before? I'm getting to the stage of having to break it!!!
