Re: How to avoid Code 42 after a plenum pull
Ccmano thanks for the pic. The gasket you are using is a Jerry's? Works fine with a ported plenum and injector housing I take it?

I always get two sets just in case  You can see the TB Coolant Port in the gaskets and if you reverse the gaskets front to back you will essentially eliminate TB Coolant. You will still have the hassle of having to remove coolant with each Plenum removal unless you actually place a pipe plug in the Injector housing TB port.   See this link for TB Coolant Blocking drilling and threading details Injector Housing TB Coolant Blocking Some tips on Coolant Air Lock in the TB Coolant Blocking link also Ccmano (Hans) has his TB Coolant Blocked also and for him you can insert the gasket front to back or back to front as you like exactly like he suggested with no sealers of any kind on the gasket (especially if you have TB Coolant Blocked).

Re: How to avoid Code 42 after a plenum pull
Great thanks for the info. I wonder if Marc blocked it. It has the TB bypass already. Will find out when I replace the gaskets.
