1998 2.5 V6 petrol Omega Tourer Head Gasket!!!
« on: 09 July 2007, 15:37:39 »

Recently purchased a 1998 2.5 V6 petrol Omega Tourer and I think the head gasket might of gone after driving 1500 miles,  The coolant light came on and I checked the water about 800 miles ago, level was fine,  but there was a white creamy oil on the cap and also in the expansion chamber, I emptied out the the expansion chamber by taking the bottom pipe off.  Last week the coolant light came on again.  This time loads of creamy oily water.  Got rid of all of it and then the next day the car overheated.  The oil filler cap and the oli have no water in them, even though the oli level is dropping.  No obvious engine leaks.

Can someone point me in the right direction, does this sound like a head gasket gone? or something else.  Car runs ok and is not lumpy.

Some history of the car.

Had 69,000 on when I purchased, the previous owner had replaced the engine at 50,000 miles as blown up engine when the oil pump went,  apparently a garage that his mate runs replaced the engine (not sure if it a full engine or not, or a recon engine.  
When I first saw the oil deposits in the water I thought it probably came from the pipe work that had been used with the previous engine (and the deposits had been left in it)

Any information would be gratefully received

Many thanks Oliver

I'll second that...oil in water tank is 99% oil cooler. :-[
think you can DIY it but not an easy one.

Oil cooler failure.....normaly as a result of not maintaining 50:50 anti freeze mixes, the lack of inhibitors can corrode the cooler.

The result is oil in the water (you dont get this on dry linered engines with headgasket failures as a rule)

I concur this is most likely oil cooler....   ....about £100 in parts, and lots and lots of flushing!

In Addition to oil cooler problem possibly also you loose coolant what you must take serious..

Will be a good chance in time you change the cooler

-Heater By pass valve (model 1998 highly possible have problem)
-In the same area is coolant temperature sensor which effect the engine  

So you will not need to work in the same area again..I changed all those

Yes...

Traffic film remover, about a fiver from machine mart, great stuff....flush the system with this!

Oil cooler is an easy job, only specialist tool needed is a crowsfoot spanner..
