i was about to rering my h22 block before putting it together, but the guy i bought the engine from said it was not necessary since the rings were fairly new as well as the pistons (type S pistons). well when i looked at the cylinder walls, there was no sign of crosshatch in them. the cylinders walls are completely blank. no scratches no nothing, but i dont know if this is the way its supposed to be with the FRM sleeves h22's have.

so my question is, is crosshatching required for lubrication (hence it retains small amounts of oil) or its safe to run the block like that.

the block came off a running car.
any help?

any help is great. thanx

edit. just fyi, closed deck h22a with Type S pistons

 

it beneficial to have a slight crosshatch when installing new rings becuase it helps them seat faster. but it will wear down . so unless you are putting new rings on dont worry about it.

 

thank you
