Guys,
I am in the market to get the steel sleeve for my S engine block.
Someone from Laskey Racing told me that they might weld the oil nozzle which is shooting the oil from the bottom of the cylinder to provide axtra cooling to the piston. They said that if I chose the forced piston (CP) then I would not need that axtra cooling for the piston.
I am wondering if they don't use the oil jet, so
how could the wrist pin and the piston oil ring get the oil for lubrication?

I'd very much appreciate for any idea

Danh

 

Pistons direct oil from the cylinder walls to the wrist pin by the action of the oil rings. There is adequate oil to the cylinderwalls without the oiljets.

 

Had mine closed on be AEBS sleeved block

 

Guys
Thank you very much for your helpful responds.

another "dump" question
when the aluminum block inserted the steel sleeve, is it any problem with the different material thermal expansion?



Thank you very much

Danh
