from what i see i can use my h22a4 crank in my h22a1 block correct. just need some verification. thanks.

 

I meant to text you back earlier, my b.

If the crank is out of a 1997 h22a4 it will work, the 98+ cranks have 55mm mains and will not work.

 

i think it was out of a 98 matt. im not totally sure. but i know its a h22a4. keep in mind this is the crank i spun a bearing so i had to get it turned. with that make a difference.

 

hey....
97 h22a4 has 50mm mains and all 98-01 have 55mm mains...so youre going to need to find out what year it came off of.

There is one thing that most people do not know....not ALL 98 models came with the 55mm mains....only the ones manufactured IN 98...the 98 models that were made in 97 (if the car was bought between sept and dec of 97 its a 98 model year) have the 50mm.

argh i know its frustrating!

yes turning it will definitely make a difference, though you still won't be able to get it in your 50mm block without a serious line hone or some ridiculous turning down of the mains.

 

measure the main and you will know.

. there is also a stamp on the exhaust side of the block to tell what year its from.

 

slightly off topic, but where exactly do you find the stamp that says is the bore is A or B size???

You beat me to it..........damn Honda with their inconsistency! I guess they had to do something with the 97 blocks though. I don't understand why they even changed them in the 1st place.

 

whats wrong with the 98 block that you have currently?

on the deck of the block, in the back, by the water pump.
