Passat 1.9tdi se losing oil

[zollaf]

could be the oil cooler. best bet is to remove it and pressure test it. this can be carried out by an engine builder, where they will pressurise the oil side of it and see if the pressure leaks into the coolant side. if it does leak, youve found your problem. if it doesnt leak then your head gasket has probably gone, but test the cooler first.

Many thanks to all the oil cooler suggestions...however took the car to a garage ...and mechanic checked with VW ...and they never heard of such a problem concerning oil cooler ...which left the only option of headgasket...the mechanic worked on the car all last week...i went to the garage on Sat and was then informed all was well and i could pick car up on Mon afternoon.....only to find out on Mon that the car was in bits ...Mechanic said they had the car running well the day before ...but now something slipped and now he has to replace the valves...as well as gasket again....What next? How can this happen?

(quote)and mechanic checked with VW ...and they never heard of such a problem concerning oil cooler).That is a load of bull,this is a well known issue.Not only that, but compared to replacing the head gasket,(which i don't think it is),replacing the oil cooler is a lot cheaper job.

I agree with Kenney, my 1999 TDi did the same as yours coolant leak from the rad fixed that and then after 300 miles I notice a bit of oil appearing in the expansion tank brownish to start. This required the oil to be topped up but on going to collect a part the cooler gave up and the expansion tank filled with oil to the top. On removing the thermostat the coolant system was completely filled with oil. The oil cooler cost £108.00 to buy plus a number of hours flushing the system tiring to clear the oil. Was told by Peter Cooper my local VW dealer that it was common for these to go.

Looks like the timing belt was not fitted correctly.........jumped a tooth or few, pistons and valves out of sync.........result, bent valves. The head will need to come off again to replace the valves and a new head gasket must be used.

If this is the case, I would expect the garage to foot the bill. Mac
