Went to the workshop again today. A failed attempt on Saturday to replace the head gasket was deemed to be due to either a too thin gasket or wrong dimension of the rubber connections between the head and the water pump. Water in oil etc immediately. When I came this morning, they were waiting for a thicker headgasket and new rubber rings, and I returned just after lunch to assist on the reassembly.
A long story in short - we were once more dissappointed. The engine fired up, but we quickly spotted water going into the oil as well as overheating again.
So what could this be? Water pump has been ruled out. Termostat as well. The head has been in for a full check inluding pressure testing. We have repeatedly flushed radiator and engine block. It looks as though the issue sits in the block somewhere; a crack or something which allows hot exhaust to enter the water jackets.
The conclusion was easy. In stead of spending more time and money on trial and error on this engine, I will try to source a new shortblock or engine. Maybe the car will be ready to leave England for Easter then?
I am of course a bit disappointed, but the car is approaching 40 years so one should expect the unexpected. And the guys at Classicarco - Mike, Gary and Mark, are almost embarrassed about all these problems plus the fact that they would like to see the car leave happily as their workshop is full of other urgent projects. But again - this sometimes goes with the trade of old cars. I guess it would not be that interesting if everything always went straight without exemption. But again - After quite a few Volvos, this is the first time an engine gives up for me. Unbelievable.

So sorry to hear about the continous problems with the overheated engine. Seems very strange and unusual for a B20E, you seems to have checked everything that could be the reason.
ReplyDeleteCould it be a frozen crack due to the also in UK unusual cold winter? // P1800ES-73
Hi,
ReplyDeleteI have been there too... BUT I´m pretty sure that Volvo reintroduced oil-cooler -72, the round one mounted behind the oil filter. They always leaks just a matter of time! =)
Hope this will solve your problem
