I was just wondering about a build up of sludge that is in the oil filler and PVC valve areas, I guess they are in a baffle as I can't see the cams, is this a common problem? The oil is as clean as and the services where all done according to the service book that was in the glove box of the half cut. The motor is out of 1990 Crown odometer says 135,000 km. Should I pulled the cam covers off and get them cleaned up, some told me to run some diesel engine oil in it to clean it out as it has detergent in it but didn't say for how long or anything else.
I did put some wire down the dip stick to see if there was any sludge in the sump but it's clean.
Any suggestions as cleaning it out or something to run through the motor to remove any sludge that may be in there.
