Replacing chains & guides will take you some deeper into the engine. Front cover & oil pump has to come off. Locating new chains & guides could be an issue you would need to resolve before getting involved in the head gasket replacement. Would be a good time to replace the front seal & even the oil pump seal.

How many miles on your engine?

hi jerry , my blk 90 has 153k on her . i do have a spare 91 motor but its being used for another project . i use this car as a daily driver and weekend warrior at the drag strip. too bad this happened she was running the best she ever has run . the car seems to lose 11/2qt of coolant every 150 miles . thought it might be the cap but i guess not . i cant find a leak anywhere . the thing is she runs the same temp as allways 180 deg (170 stat) she doesnt get hot . but the plug on no8 has crystals on the 4 electrodes (bosch fusion ) but it doesnt look steam cleaned like when it happened on my other 90. so i am at a loss to what gives only thoughts are head gasket is starting to go. any other thoughts ?????/ i am all ears
