I am in the process of replacing the head gasket on a 2000 S70 Turbo with 130.000 miles on the clock. It has had a slow coolant leak for the past few months and eventually overheated and now I am getting coolant into cylinders 4 & 5. I have removed the head and purchased a full gasket kit which has new valve guide seals. I was planning to clean the head and do a (hand type) valve job before reassembling it. Compression was good, it did not burn any oil between (5K) changes, and the engine is quite clean (except for varnish) for its age. I do not have a tool to remove the valve keepers and it looks like I need to add an extension on an old "C" type compressor because of the recess and lack of clearance around the valve springs.
Am I overdoing it??? Do I really need to go to the trouble of removing all 20 valves just to do a hand lap and replace the seals??
I only use the car for winter, keeping my new S60-T5 off the road for a few years.
Thanks for any replies/opinions/suggestions.
Tom
