one way valves?
on my dohc zc which I turbo"d I'v been getting the engine light to come up when I boost it,,and its the map sencer, I have 1 valve in it already at the front of the throttle body where the vacume line is to the map sencer,,,,, I'm wondering if that is enough or do I need to put more in and where?

Re: one way valves? (grover)
Most threads I have read that talk about the check valves seem to make it pretty common to run 2 or 3 check valves.
You said that you are getting a check light, but have you checked what code the ECU is throwing? If it's for the MAP sensor and you only get it during boost then it pretty much narrows it down to the check valves. I would suggest you add another in line with the one you have and see if that clears it up.
