Hi ,

Im trying to do a boost leak test but the air goes always in the exhaust .


I have try to rotate the cams to TDC and I have try almost all point by turning the cams 1/8 each time but I cant get any boost in the system always leaking in the exhaust.

its the HKS 272 cams or Im doing something wrong ?

by the way its for a 2006 evo IX MR with Mivec.

Thanks

Step 1 pressure test the system up to the Throttle body (keep throttle closed).

If no leaks, then move to Step 2 (test throttle body and injectors seals).

Step 2 : open throttle and pressurize system.

 

If your not getting any pressure you have 1 of to things, you compressor is junk or you have one or more major boost leaks.
