I had thought of using a smoke pellet as saw that on YouTube the other day. Tried being in the boot and nothing was obvious

Omega General Help / Leak in boot
« on: 29 April 2024, 14:03:29 »
Has anyone had an issue with water leaking in the boot of a 3.0 saloon. Have just emptied the boot and the carpet is soaked. Have looked for any water marks but nothing obvious. Can see the vents on rhs behind the bumper where it could get in. But any advice would be appreciated

It’s a 3.0L and think they are genuine GM downpipes. As only one side is a problem will have to it there is an issue with those flanges.

I answered the question earlier. I have fitted the genuine ones and the o/s failed. No sealant was fitted. What should it torqued to?
The only other thing I can think is speed bumps causing it. Can you get standard springs as they all seam to be lowered ones. It has eibach ones on it but would rather it standard ones.

Yes had 1 set but it went on the drivers side. Do you know where I can get them from? Tried at the dealer who said they were discontinued.

Omega General Help / Omega V6 downpipe gasket
« on: 26 February 2024, 20:54:22 »
I have had issues with my 3.0L V6 exhaust downpipe gasket. Each time I change the gasket it fine then it starts blowing within about 6 months. I’ve tried different makes of gasket I even had a genuine GM and it still went. I have checked for flatness on the flange and they seam ok.
Can anyone recommend a gasket or a fix? It only seams to be the o/s which would point to the manifold or downpipe flange!! Have a mot in 6 weeks so would like to have a permanent fix.
Any gasket recommendation would be good.

No they are original GM cats, been on the car since I’ve had it. Only had this issue the last 12 months. And I do tighten the same sequence as you say.

Omega General Help / MV6 3.0L exhaust blowing
« on: 27 October 2023, 21:07:20 »
I’ve had an issue with one manifold to Down pipe (cat) blowing. I’ve changed the gasket about 3 times now cures the problem and 2-3 months later happens again and gasket has blown. I’ve tried different types of gasket with no luck. One was a genuine GM part.
I’m worried about snapping off a stud if I over tighten it. The flanges look ok but can only assume one isn’t flat as only have the issue on the o/s
An advice would be appreciated

I’ve been trying to remove my steering wheel, everything is removed (air bag, nut) but it won’t come off the spline. Have soaked in WD40 any advice on how to get it off would be great!!! Was removed about 3 years ago.

Thanks for the info, the 2 previous engines one had the big end go, and the other a massive oil leak so changed to the current one. I still have old one in my garage.
When it first over heated it was dry for a couple of weeks, and there were never any wet patches on the ground. The HBV was replaced a couple of years ago along with all the hoses when the engine was fitted and a new radiator.
I will check all the things listed above, but can’t find a leak. Any more ideas would be great.
Thanks

Omega General Help / Engine water loss.
« on: 05 November 2022, 13:17:31 »
A few weeks ago I went to London and my 3.0L MV6 overheated.
I topped it up and it has ran fine. But ever since it has been using water.
Can’t find a leak anywhere but needs about 2l of water a week. There is no water in the oil, or oil in the water. Has anyone experienced anything similar on a V6? The only think I can think of is the head gasket and it is burning off the water.
Have already changed the engine twice so if I can’t sort the issue may have to scrap the car.
Thanks.

Goes for MOT next week so will get them to check it over. But has only done 2500 miles in last 2 years, and not driven in winter. So will have a another look but sounds like the struts are correct.
