will a newer b18b1 flat valve cover from like a 98 and up fit a b18a1 which has the valve cover with the splines in it?

 

anyone?

 

Ill bump ya but im pretty sure you can the onyl hold back that i am curious is where would you run the hose on top of the vc to?? Is it a vacum hosE?

 

Anyone knwo for sure i wanna know what you have to do. I have heard of people welding a chunk of alum in the hole on the vc. But couldnt you just direct the hose to the im and jsut plug the other hole on the im???

 

Yes it will work.

I have the two valve covers and they will work fine and bolt up. Only thing is the b18b valve cover has the pvc port on the top of it while the b18a has it direcly to the intake manifold

 

any pics??

 

I'm bumping this cause i want to put the 94+ ls valve cover on my b18a1 too. Pics please

 

anyone?

 

bump

 

pics of what? it will look the same as a b18b engine

 

Well how to you route the hoses the right way??I know the 96- had it on the im and it connects to the top but the 96+ have it on the vc.

 

You can T the pcv hose into the factory system (canister on back of block to IM) or you can put a vacuum hose cap on the pcv on the new valve cover, or you can run the new valve cover PCV to the IM and cap the port on the canister.

Best way is to T it all togeher and get the most crankcase ventalation

 

So you suggest connecting the valve cover, valve on the runner of im, and the top of the im??
