When putting a b16 head on a ls block is there a oil hole that needs to be blocked out on the block and if it's not blocked out what will happen?

 

The hole you need to plug is in the head. You tap it and plug it.

If you dont you wont have any oil pressure for the vtec system to engage

 

That's d hole for the oil line feed from the block to the head you're talking right. But isn't there a hole dat needs to be plugged on the block itself?

 

Vtec blocks have a oil passage for the head in the block


Non vtec blocks do not have this passage

Thats why vtec heads need that hole tapped and plugged.

Also when doing a vtec conversion There is a line that goes to the side of the head that feeds the vtec system

Dont make it more complicated then what it is

 

Ok why asked is cause I recently did a ls vtec build and i see alot of oil leaking from between the head and d block and the mechanic says he torqued the head down properly so I don't know where that oil coming from

 

If he didnt plug the head or use teflon then it would be coming from there

 

That's what I was thinking too

 

Everything you need to know about the LS VTEC
