Just doing some homework and came across this little tidbit. Can anyone elaborate on why, or why blocking off the oil squirter would be a good thing?

 

the under piston oil squirter's were originally designed to keep the pistons cool. they were NOT designed to lubricate anything.....

the OEM cast pistons run hotter than aftermarket forged pistons. the forged pistons dissipate heat much better than the OEM cast pistons so many people elect to have the squirter's removed when installing forged pistons.

by removing the squirter's and plugging up the holes you gain a little more oil pressure....thats all

personally i would leave the squirter's in anyway.......in a turbo honda engine all the piston cooling you can get is a plus.....

 

Thank you sir.

 

I just bought an 84mm erl built block and the oil squiters are plugged.

 

I plugged mine as well. You will get a little more oil pressure without the squirters.

 

Also with the squirters plugged you keep everything a little more equally balanced because all the oil squirters dont really put out the same amount of oil.

I know that it isnt that big of a deal. I know thats another reason some of the All-Motor guys to it in their high reving motors. Kind of to try to keep everything in the rotating mass equal

 

leave em or plug em it wont really matter when u run quality forged pistons. the cooling effect is kind of comforting plus it prolly keeps the piston temps more consistent.
