BIG head problem
I think it has been said here about 999 times that you have to clean out the bolt holes for the heads. If you do not, you break things that you cannot easily repair.
Ok make that 1000 times.
I went to Best Buy and bought a can of Fellowes Compressed air. I put the little straw on the end of the nozzle and stuck it all the way down in the hole and sprayed it out. The coolant just shot right out of there.
I then took a rolled up paper towel and stuck it in all 10 of the big holes on each side, and the towel came out just barely damp. It didnt even encounter enough to soak it.
There really is no excuse to not get all the coolant out. Just use air-in-a-can.
