Where is block drain bolt on H22a?
Where exactly around the oil filter is the coolant drain bolt on the block of a H22a? Is it right beside the oil pressure switch under the oil filter? There is a big leak and it's pretty messy. I don't know if its oil or coolant. And there is a hole that looks like its missing a screw that may be the coolant drain plug... It's slightly under the oil filter and beside the oil pressure switch. There is another bolt above the oil filter in the corner that looks like it may be it but it's very difficult to get too.... Which one is it??? Thank you!! and Happy new years!

no, thats just a mounting point for something, i don't remember what. probably the block heater or something, but its just a threaded hole, doesn't go all the way through the block, and doesn't hit a coolant or oil passage, i just checked
so thats not your problem

find out if it is oil or coolant. if it is oil, i had a similar sounding problem recently. take off the oil filter and undo the bolt in the center and take out the spout. iirc the socket size i used was 1 1/4". check the back of tht oil cooler or w.e it is and there should be an o ring. mine recently blew out and i leaked a truck ton of oil
