Hi all,
I recently picked up a 94 FZJ80 and have started building/repairing the truck. I recently replaced the valve cover gasket since it was leaking oil pretty bad and the bolts were not properly tightened down. I thought this was my only leak, but I was wrong... I noticed oil is also leaking from the distributor and I have ordered a replacement o-ring and will put that on once it is delivered. I also changed the oil and oil filter after the valve cover gasket and have been monitoring the levels very closely. It doesn't seem to be leaking much at all. Getting to my question... I was under the truck cleaning all the sludge and grease away and I noticed a possible leak around the rear of the head gasket. I am not sure if the sludge was already there from when the valve cover was leaking. I wiped off most of the sludge and it looks like black tar. I checked the coolant and it is still red with no signs of oil in it. Would this black sludge be coolant/oil mixture or just oil with dirt in it? Do you think the HG would be leaking? The truck isn't overheating at all and I've done some trips/offroading with it being completely okay. Any help would be awesome!
