thanks guys for the advice, knd of thought that it would be the scrap yard, i can not break myself as have no space to put her while stripping down so looks like its off the the scrap yard. So so sad really top car to drive.

admin edit

Hard lesson lernt here but will deff get another V6 Omega in the future maybe spend a little more money next time as i can honestly say on the M25 this is one car that can hold its own against the A4's and A5's with no problem at all.

yes def from the exhaust clouds of steam put hand over the pipe and could smell the anti freeze, the oil cooler was done in december as when i brought the car in september there was no anti freeze in it so had the system flushed, which brought out loads of gunk, rad weld and all sorts, then about 6 weeks later the cooler went oil in the header tank, had that sorted £350 later water pipe at back of engine slipt, sorted that and new hbv and now this, love the car but spends more time in the garage than on the road at the moment.
Far to nice a car to right off just wont to make sure that if i spend the money it will be worth it. But will get a compression test first as you adviced.

It's unusual for the HG to fail on the V6's, although ISTR that there was a dodgy period around 1998 Although these tend to fail between the waterway and the outside... Very rare to go across the fire ring Before starting work on the HG it needs a compression test to confirm this is the fault

If it is then he needs the timing (locking) kit to time it up correctly. The heads may not need skimming but do need checking.

Hope that helps

Thanks very much yes it does help i just cant understand why the water is going straight out the exhaust, is there anything else worth replacing whilst there thought skimming the head would just make sure the job was the best to prevent any future problems

Thanks again

Omega General Help / head gasket ?

« on: 08 February 2012, 09:30:01 »

hi guys, can i ask you for some knowledge again, I have 1998 3.0L V6, been having a problem with the coolent of late, loosing water had a couple of split pipes which have been replaced, HBV and oil cooler also replaced but still loosing water.
This weekend car had a full flush new anti freeze all bled and sorted heater nice and hot again perfect no water loss.
Came to go to work monday night drove 3 miles down the road and loads of steam from the exhaust, check coolent, pulled over let her cool down and topped up 50 50 water anti freeze mix drove away 3 miles later still steaming like a loco and check coolent.
Got her to the local garage and with EMS light on miss fire tried to top up with water but drank 7 liters and straight out the exhaust.
The question is has the head gasket gone or is there anything else it could be.
And what are the pitfulls i should look out for if I get it sorted. I know the heads will need skimming might as well do the cam belt and water pump at the same time is it worth it and would my trusted man need any special kit to get her all back together and running again.

Sorry for the long post !!

Omega General Help / Re: URGENT HELP !! Head Gasket Replacment

« on: 11 December 2011, 12:54:04 »

Nah, not HG

Oil cooler

On the upside, oil cooler is easier and probably a little cheaper, about £150 for the parts.

Mayo on cap is most like a combination of short journeys and poor oils (Castrol GTX/Magnatec is known to do this)

Hi thanks for the reply, she had an oil change 2 weeks ago new semi synthetic uni part as well as a coolent flush, does not seem to affect the performance, I only do motorway millage nothing around town never less than 50 miles, so a little worried about taking her out at the moment.

Omega General Help / URGENT HELP !! Head Gasket Replacment

« on: 11 December 2011, 12:42:54 »

Hi Guys can I call on your help again, i have a 1998 Omega 3L V6 on checking the water and oil this morning I have found that the water res has loads of oil in it and i white discharge around the top of the filler cap, the oil filler has caramel residue around the cap. So I guess the head gasket has gone, I do about 600 miles from Gillingham Kent to London everyweek and need my car, is there anyone out there in the kent area that can raplace the gasket anytime soon and give me some idea of the Price ??

Thanks again
Brett

Omega General Help / Re: smoke form drivers side of engine

« on: 28 October 2011, 14:20:48 »

Welcome to the forum, Brett.

Regarding problem 1, you need to read the fault codes from the engine ECU. Here's a guide to help: http://www.omegaowners.com/forum/index.php?topic=90581.0. See if you can paperclip test it and count the flashes, then post back with the codes.

Problem 2 is almost certainly down to leaking cam cover gaskets. These are not easy to spot from above but a very common failure. They can also cause oil to leak into the spark plug wells which eventually breaks down the insulation on the plug leads and causes a misfire. This might explain problem 1.

There is a guide on cam cover gasket replacement here: http://www.omegaowners.com/forum/index.php?topic=90542.0. Be sure the clean the breathers while you're at it, and we've found that only genuine GM gaskets tend to last.

Thank you for the welcome and indeed the help I will give the paper clip test a go, as for the cam cover gasket I am not the most technical of people to say the least so i will have to find someone local to take that on but many thanks indeed.

Omega General Help / smoke form drivers side of engine

« on: 28 October 2011, 13:59:45 »

hi can anyone help me, i own an omega elite 3.0l have had it for about 6 weeks. I do about 70o miles a week on the m25 / 26 and of late have 2 problems.
1) the engine light comes on when sitting at around 70 if i speed up it goes out but then comes back on again. it pretty much inconsistant no pattern to the problem, comes on a lot at low revs although the car runs like a dream.
2) the second problem is that when the tempreture is up 90+ or i am sitting in traffic there is a cloud of white smoke from the drivers side of the engine and a smell of burning oil. I can not see and leaks !!!

Also does anyone know someone or somewhere near gillingham kent that can service and maintain as i love this car its by far the best drive i have ever had around the M25.

Thanks
Brett
