having rebuilt my engine on my version 2 sti to forged , i found out that there were oil squirters under the pistons, is this standard for an sti block, as i going to rebuld another one as spare and would like the same spec when i source a block

 

Oil squirters where fitted to closed deck blocks found on some early STI models.

 

Stick to a closed deck block with oil squirters, as they're the stronger block.

And you will not find these EJ20G type blocks after 1996 they will have to be pre 96. The hatching on the oil filter body part of the engine is the give away to a closed deck block. There will also be some hatch markings above the oil pump on the engine blocks. None of the other hatchings mean anything.

 

thanks i built engine and didnt really pay any attention when building it, but looked at the pictures and yes its is a closed deck block

 

Just double check the clearence between the base of the piston skirt and oil squirter, they can catch!

 

They will catch on after market pistons which have not been specced correctly. This could be due to pistons or rods.

In standard form there should never be an issue with this.

 

thanks i did check this as had to replace one when i done the engine thanks for your help
