k motor is back in...intake off. went to put it on and noticed a hole on top off the block right below where the egr would be. this is not an intake to block/head bolt hole. looks like a sensor would screw in there but i havent any sensors to put there. the block is from a 96 lt1 (i think)and my car is a 93 z. i plan on just pluging it but thought id throw the question out there.

also when i fill it with water should i fill it thru the top of the w pump or just the rad or both?

can i loop the throttle body water inlet and outlet together?

thx.

 

last first yes u can bypass the tb, they make a kit but its cheeper to get a nipple and a couple clamps from the hardware. fill at the pump till its full then after sealed up do the radiator. bleed the air out as u fill the rad. then bleed again after u start it. drive it a mile down the road and back and refill and bleed air again. first last if i remember right the 96 has the oil pressure sending unit by the egr and the 93 is by the oil filter

 

crabby's right it is a oil pressure sending
