built ls/vtec going into 97 ek coupe.

my block did not come with the black box breather, and i dont see the nipple ( i know some years didnt have this setup).

i know ls/vtecs pretty much need something to help the blowby etc. so what would you run?

id like to run a catchcan, but im not quite sure how to hook it up, i dont think the big nipple on the vc to can to intake will do much to replace the pcv...

any help is greatly appreciated!

 

which blocks come with the black box and which didnt?

 

im not positive which was which. i just no when i bought my block the guy didnt have it so im not sure if mine had it originally or not.

i think i need to run a line from where the pcv box connects to the manifold but im not sure...wish i could afford the endyn breather.

bump.

 

ok so after reading alot...i found my block never had the black box (the big hole is plugged).

so whats my best bet on a catch can for my high comp motor? should i do two fittings on the front of the valve cover?

 

should be a port on the back of the block to tap into

 

just run the 2 hoses to a catch can with an little air filter and eliminate the pcv system all together. I have an obd1 with the black breather box and i'm running the 2 hoses from the little box and the one on the vlv cover to a catch can, thats it thats all. **** the pcv, scavaging crankcase fumes is so low performance. I will be drilling the holes even bigger eventually to run bigger lines for even more cc ventilation. but doing this won't pass smog test.

 

There are 2 plugs on the back of the block in the oil return passages that can be removed and replaced with a different plug, one that has a threaded hole in the center that's usually used for some type of temp sensor (such as a rad fan switch). There's an article somewhere on here that elaborates on it for a pcv/catchcan setup, do a search for it and you should find it.

 

yeah i figured that out too bad they are hella stuck in there.
