Perhaps we will get some help here, but from what I've been reading suction from the dipstick tube means the ccv system is working as it should. So, the increase in suction you're hearing could actually be an indication that you have done well. Now I'm thinking that if there is a suction your hearing with the stick in, then perhaps you have a broken o ring on the stick. It has I believe 2.Just got it all back together. It runs better...but I can still hear a misfires and there is tremendous suction from the dipstick tube (possibly more than before). This is not the outcome I had hoped for. At least now it doesn't start go up to 1500 rpm and then drop dead. Now it will run, but the idle is unsteady.
Hmm...where to go next?
