it won't be cam timing, they're mechanically spaced from cylinder to cylinder and as such will give even results across the board, dew to the inconsistency between cold and hot I would cold test all again then wet test then hot test incase the tester wasn't sealed in properly, and test all

but I would say from what i have read you will need to find someone that can do a leakdown test, if there is a valve issue like a small chip or crack in one valve it will still give some compression in a comp test, the leakdown will comfirm

to do a leakdown you need a compressor and a attachment to go between the hose that goes to the motor and the comp tester gauge that you can attach the compressor to, to do the test you need to find the point where both valve are shut, pump it to a set psi and then see how long it takes go drop to 0

I don't have a leak down tester that's the only reason I havnt done it yet, are they expensive ?

Google it and it will tell you how to make one or pay a workshop an hour's labour to do it for you.

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      What about if you just give it direct 12v and earth?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
