Hi
I just purchased at a low price a 98 V70 2.4 Turbo wagon with 160,000 miles. It has oil in the coolant and also consumed coolant. During the 250 mile drive home I had a low coolant alarm twice and had to add some to get home. The back window had an oily film on it that I assumed was antifreeze.

I have pulled the head after a few days of getting parts off the turbo was very tough but it finally came off.

The head gasket has no major visible flaws but the pistons all seem to have little carbon build up like they have been exposed to water. I will replace the head gasket and start to put it back together. I will check head for warps etc. Is there anything else I should look at while it is apart. I will also put in a new radiator. A radiator flaw would explain the oil in the water but not the coolant consumption.

Discouraged at complexity and lack of eureka I have found it. Steve in Maine

Anybody want to trade a V70 for a 940?

but what did ya pay for this car? Also I heard reassembling the upper cams and cam covers needs some special type tools and sealants and do not use gaskets. Let us know how ya make out so we can learn from it!

I got the car for a price that meant that if I had to put a new engine in it it was still a fair deal.

I have made some tools and have the head off and put the lower half of the head back on a retorqued it down. I need to make a cam holder tomorrow to start the upper head assembly. I have the special goo instead of the gasket. The concern I have is if I am on the money on the cranshaft timing marks. There are to very faint scribe lines on two adjacent peaks. When I line them up #1 cylinder is about 1/16 " down from TDC Is this right? I got the belt off and the new one on without taking the big pulley off. The complexity of the v70 compare to my old 16v 740 is amazing. About 20 little plugs and sensors with wires running everywhere and the belt access reallys sucks. I will keep you posted as it goes back together.

I have heard that even "local" indys won't even touch head jobs on the V white engines as all the alignment crap needs certain gaging that volvo has developed in setting tools. But as all good gear heads know.....there has to be a longer more methodical way around it without the gages!

Hi Steve,

Leaky radiator would/could explain the coolant consuption, as could a leaking heater core. As for the film on the rear windshield, I would lean toward a possible rear main seal causing that, or turbo oil return line. Sounds like the vehicle has been driven hard and/or not well maintained. Where in Maine are you located. I'm in the capital area.

Thanks for the tips I'm in Jonesport. It has oil in the coolant. I will start to reassemble this week and will replace the radiator and check the turbo oil line. It did not seem to use any oil on the 250 trip back here. One other think I lined up the marks to dissaseble and was surprised to find piston #1 is about 1/4" down the bore when I lifted the head. I will recheck cranshaft pulley but man it is tough to see the tit it is supposed to line up with. Any further thoughts would be welcome. Thanks

This might help with the line up.
