    Syclone #569 needs some

    Ace bandages.

    Bought this truck 2 weeks ago. It was pouring Oil out of the drivers PCV breather which was re-located to the inner fender ever time the truck boosted hard. It also leaves a nice trail of blue smoke behind it too. Sure enough under the truck was covered in oil, look in the fender and I felt like I was Jed Clampett. Oil everywhere.

    Today i do a compression check on each cylinder. It goes like this.......

    Drivers front to back

    #1 90 psi
    #2 70 psi
    #3 60 psi

    passenger front to back

    #6 150 psi
    #5 140 psi
    #4 120 psi

    Checking the plug that goes to each cylinder, they are white but not too white or pitted ect.

    Now on to my questions???????

    If the previous owner drove it this way for 1-5000 miles going based on the oil from the breather, How much more damage could he have done? (i cant do much more mechanics cause lack of room, tools, ect.)

    If i am changing valve seals ect. what about head gasket or anything else?
    Should I do full rebuild?
    How much am i going spend to have someone do this?


    The truck has 135k miles on it. after market turbo that was set about 26 psi with stock internals. I bought it and turned it down to about 18 psi. Drove it 200 miles and now have torn the truck down to fix. paint, clean, and tune it up.

    New video I never posted here shows me driving it around on the th350. It's pretty fun. Lots to tuning yet to be done.

    In and driving. It was a long day, but I wanted to grab a little bit of video of it driving. If weather holds up I'll do a little street tuning and get some good vid.

    i see. I planning to do VP fuel in mine. Iím running on 340 racetronix. Renz intake is very good flow equal than stock intake which will hurt your #5/6 cylinders because of stock intake design. Surprise me there no flame coming out of the exhaust while on the dyno. You should remove the power steering and AC if had it then you get more hp. Lol
    I won't be doing headwork or intake manifolds or anything like that on this motor. I'll reserve nice things like that for a v8.

    The truck already has alot deleted, entire hvac system is gone, abs and cruise are gone. Full tank and no driver it weighs 3270lbs. Still have power steering mostly because my brakes are hydroboost.

    It's getting there. I was really hoping to see the fruits of my efforts with the Holley, but the transmission gave up. I am currently converting to run a th350 with a CK Performance mechanical diode drum and a manual valve body.
