Hi everyone, I recently turboed my civic and I am having some trouble with my oilpan gasket, rear main seal and possible my valve cover gasket.

I also have a bit of an erratic idle once the car is warmed up going from 900 and steady to 500 and almost dying every minute or so.

I am not sure but I think I may have an issue with my pcv valve not opening and closing as it should and I would like to have a look at it and possible clean/replace it.

The car is only making about 140whp and it's a 6 psi on a t3/t04e 46 trim turbonetics so my understanding is a valve cover breather and a good functioning pcv system should suffice.

Does anyone have a printout from a helms manual of where I can find the pcv valve on a sohc zc or (d16a6) and possibly how to disconnect it without breaking it.

I searched and the older archived threads don't have pics that work anymore.

Thx!

 

the PCV valve is behind the fuel rail right up on top - follow the large hose coming off the front of the intake manifold (in the center between the 2 smaller hoses) which goes to the PCV valve

 

is it better to get access to it from the bottom or from the top?

I currently have the downpipe off as well as the bracket between the block and intake manifold.

If I go at it from the top do I have to remove the fuel rail?

 

from the top (this is SOHC ZC VTEC, but they are all about the same)

 

can't see the image from work but thx I will check it out tonight!

Any precautions to make sure not to break the valve and can I clean it with brake cleaner?

 

and it doesnt open and close..its a one way check valve...

edit: or **** just buy a new one

 

under boost how would you run the pcv lines wouldnt it pressureize the bottom end more?

 

just run the hose to a catch can and vent it to the atmosphere, forget the PCV valve

 

bot wouldnt a working pcv valve and black box with a breather off the vc be enough at this low boost lvl?

A friend had the same engine in the same car with the same system and he was making about 50whp more and never had this issue
