i just picked up a 95 b18b1, and the nipple on the im where the hose from the pcv valve is capped with a vacuum plug. i want to replace the pcv vavle and hose, but i cant for the life of me find out where it attaches to the head. it isnt obvious like the 96+ b18b1 engines where it is right on the valve cover. can anyone help? thanks.

 

Me having a 2000, its on the top, GSR is under the IM, and just a quick guess I "think" the earlier model b18b1 is under the IM as well, dont hold me to it, im currently looking into it further for you.
"It's well-hidden. It's in between the injectors, in a web of aluminum
between the intake manifold runners."

 

right on man, thanks for the help.

 

ok apperently the 94-95 ls motors have a baffled black box on the block like b18c1 motors do. the problem is my motor doesnt have the black box. it looks like someone capped it off. is there any way to add a pcv setup easily? does anybody know if i can just swap out valve covers with a 96+ or can i drill the valve cover and add a pcv valve????

 

As far as I know the valve covers are interchangable. I wouldnt drill yours to make it fit.

 

ok right on i will see if i can find one...

 

can anyone provide pics of the stock 94-95 b18b pcv setup???

 

On or off the car?
