    Bad Idle and A/f after a full engine rebuild , Need Help.

    Pressurized air and soapy water in a spray bottle will do the trick, but smoke is 100x better, and not a spot of mess either. When you pressurize your system, if you choose to pressurize the turbo too, make sure the turbo doesn't spin dry. Would you mind trying something? After a lot of f'n...

    Bad Idle and A/f after a full engine rebuild , Need Help.

    Ok, than your VF should be reading something. Have you driven the car yet? This is beggining to sound a lot like my car...hmmm. I'm going to follow this thread closely.

    I think the 18:1 AFR's indicates a lean condition lol, no pun intended:naughty: BTW edit on my last post I mean PTT, not spd. density sorry.

    Bad Idle and A/f after a full engine rebuild , Need Help.

    Whats your mainscale at? Is your ignition and valve timing good for certain? Some good news though your VF should read .01v if your running speed density, stock o2 unplugged. You are right?

    check engine light ??

    Still a good score, I would do the basics, compression check, fix that code 11 Like jetjock said, it'll hide all the other codes. Anyways good luck man.

    Low coolant light on

    Couldn't it be a small leak in the hose from the oerflow to the rad? Allowing air to come in on cool off?

    check engine light ??

    400$!!! Good score man! If your doing what say, don't diconect the jumper cables until you shut off the car! Your alternator doesn't like it.

    PCV system/ explanation and mod

    Interesting theory. Although I think that is what the oil pump is for. But I don't want to get into that. Honestly I don't think I could see that much vacum in the crank with my setup, if you think about the shear volume in there and the size of the TB orifice. Plus at cruise your not pulling...

    PCV system/ explanation and mod

    Hear me out, If you don't put the check valve after the turbo inlet then you can never truly get vacum in your crankcase, atmosphere will simply flow in, correct? No matter the volume "sucking" into your TB(Within reason). That is simply fluid dynamics. If you were popping your dipstick out I...

    PCV system/ explanation and mod

    Or a shot of carb cleaner now and then...Anyways I thought that was the point of a catch can...? Or do you not have one? IJ, I figured the check valve would be better between the turbo inlet and the catch can in your diagram, then you could get manifold vacum on the crankase? Although I like...

    PCV system/ explanation and mod

    The "main" vacum needs to be behind the TB valve(intake manifold), or else you don't have much pressure differential. 7Mboost: Not really, the majority of fumes travel from the crank(valve covers) to the TB.Period. The point of the CC is to intercept this. I think as the turbo inlet as an...

    I deserve the Hall of Shame....Code 24

    Atleast it didn't make it to the turbo, it's a shitty way to loose one:naughty:

    PCV system/ explanation and mod

    I did a similar setup, valvecovers to a "T" one end directly to the TB, other end goes to a check valve then to turbo inlet, I liked the idea of having a vacum on the crank(Not sure if it can be fully acheived with the stock setup). And when I hit positive mani pressure, the check valve opens...

    PCV system/ explanation and mod

    You get the most vac on decel, followed by idle. There is nothing wrong with the stock setup, if you have provisions for it. I would put the catch can between the valve covers and intake manifold, how much time does your car run under positive manifold pressure vs not? Think about it.

    Valve buckets & shims got all mixed up (Stupid red squirrel!!!!)

    Yah, I'd be curious with the .005" but atleast its on the intake side(doesn't expand as much as the exhaust) As for the three exhaust @ .013", they may tick, and ultimately not open as far, or stay open as long. Just to clear this up, you want the cam on the LOWEST spot, 180degrees away...

    Valve buckets & shims got all mixed up (Stupid red squirrel!!!!)

    Use a feeler gauge, put the cam at its base circle,(lowest spot, valve fully closed) and slide your feeler gauge inbetween the shim and cam lobe. It's take a lot of practice to get the feel for it, but once you have a "slight" drag, your there, this is of course if the number on your feeler...

    Whats your setup? What did you run also:naughty:
