i was woundeing if i can run the oil feed line off the head on a ls motor becouse i was running it off the sending unit but my turbo started to blow oil through the seals and out of the down pipe and the shop that rebuilt the turbo said that it was getting to much oil pressure and was blowing out the seals my buddy is running his line off of his b16 head or could it be that my feed line is to big it is a -4 line please help

 

get a -3 line

 

if you use anything bigger it's best to get a oil restrictor though the -3 line would be the best bet so you don't have to go through the hassle.

 

I would not run it off the head
Just get an oil restrictor
