Omega needs head gasket replacement ?
« on: 26 December 2007, 10:10:35 »
hi guys :)
hope your all having a nice xmas...and Happy new Yr  ;D

noticed on one of the posts a comment,

"Not sure why you have the impression that the 2.5 is unreliable, they should be as robust at the 3.0.  Often an oil cooler failure is mis diagnosed as a head gasket failure: that could be why lots of people are after relacement engines. "

this opened my eyes a bit as i have a recently " dead"  :( 1995 2.5 v6 omega cdx sitting outside my flat, local garage put a tester on it and told me it needs head gasket replaced or new engine, £600 + or £1000 if all goes well...i was gutted..only bought her in may this yr and paid £1200 cos in nice condition, i was tempted to spend the £600 and get her back on the rd,but my woman convinced me to buy another car and sell omega on as scrap or spares, I've held out on selling my lovely omega for a month but dont know how much longer I can hold out, lol..the problem is who can you trust and is it really head gasket ? Help !!  ( guys Im driving a citroen est now, so you can see why I need help please )

We need some more info on the symptoms please

Is there sludge in the dipstick?
Mayo in the coolant tank?
What does it run like?

What sort of "tester" did they use? Compression tester, or emissions snifer in header tank?

While it happens, HG failure is rare and is commonly mis diagnosed, so it's definately worth checking out to be 100% sure.

Even if it is the head gaskets, it's not a difficult DIY job, and costs about £50 for a gasket set, + bits and bobs. £600 is OTT.

It sounds like it could be as simple as a heater bypass valve failure, causing the coolant to over pressurise!

Flush out the coolant system, check out the HBV and see what happens! Could also be a blocked rad, ESPECIALLY if you have put radweld rubbish in there  :'(

Water from the back will most likely be the Heater Bypass Valve...

Also with you using this radiator fix, its well worth flushing out the coolant and replacing with fresh once you change the HBV.

Remember that if you get air in the coolant system it WILL over pressurise............and a when a coling system cools down and the coolant contract.....it draws air IN

sounds to me like the heater valve, if it was the oil cooler then the header tank would be full of oil...

Change that valve bud bring her back to life....  :y :y :y

could be such a simple fix, just think how gutted you would be if you scrapped it to then find out it might have just been a £50 valve....  >:(
