Boost leak: Secondary air valve
#11
Thread Starter
Oh, i see! Ok, so instead of having the air pump outlet line to the aftercooler, i attach it to the sc air inlet tube. This way it doesnt see boost, but is still able to inject the air.
Ill try it and report back! Many thanks!

I used a dual barb fitting for a heater hose to fit it. One end went into the intake elbow and on the other end i cut a piece of hose (5/8 i wana say) put it over the barb and the oem air pump hose on top of that with the oem pressure clip
Hope this helps. I know i found the dual barb as a radiator or heater hose repair or extender kit worked like a charm

Sorry to revive this thread but even if you don’t have it connected to the aftercooler and instead have it pull air pre-compressor... wouldn’t that air valve on IM start leaking as soon as intake manifold sees boost?
Are these IM valves prone to leaking air? If so where can I get a block off plate?

That air valve isn't even tied into the pathway of the intake manifold/combustion chamber so how is it going to leak boost. They should have mounted it near battery or something rather then on the intake manifold so it wouldn't confuse people I guess. It purely injects into the exhaust pathway on cold start up to help reduce emissions.

Its typically a source to run the bov, or boost gauge, there is no logical reason to keep that vac line in oem use to the injection valve. If your hypothetically having a boost leak there, you are bypassing it anyway to resolve.

I'm only saying that it could be a possible source for a leak. I don't know if the posters have it hooked up or not, I cut mine off the manifold.

I think I’m starting to follow the whole leak path. Correct me if I’m wrong here but... boost exits through air-pump hose that’s connected to the Aftercooler. Then boost bypasses the air pump itself, then the valve that’s on the IM and finally boost is leaked into the exhaust.
Does that sound right?
