As some of you may remember my saga of the 87mm dropping oil pressure and me running it with vinegar in thr radiator and even dish washer detergant in hopes of allowing the coolant to reach all internal parts and thereby helping the oil pressure problem since replacing the mains and the oil pump guts didn't help. Well today I pulled the head and the brass runner that goes thru the head. There were a lot of water ports clogged into the head and the block.Going to send the head off for a hot tanking and I'm wondering if theres something I could do to the block to clean all the ports without having to split it to hot tank?
