  • Head / Block Cleaning

    So I found my overheating issue, it still ran a little hot after new water pump, thermostat, popit valve, etc. . I was able to remove the exhaust jacket and the head with no broken bolts . Apparently this job has been done before with anit-seize on the bolts ! So my question is what is the best way to clean all of this out ? I thought maybe pressure washer with a wide tip. As far as the block it looks pretty good but has lots of white salt powder. Since I have everything open any other maintainence I should do ? Thanks in advance.

    Just to clean out with a small screwdriver or pic to clean out all the holes and passages but protect pistons and cylinders from getting trash in them.
