    @marek0086 cutting it in half with a bandsaw to see if there really is a crack or leak where you think there is. destructive testing leaves you with a pile of junk in the end, regardless if the part you tested was good or not.

  6. Duckyistrippin Says:

    @marek0086 no, this is NDT. destructive testing would be cutting open the block to see if it was good or bad. obviously, if it was good you still destroyed it anyways. all tests at an auto machine shop are NDT dye chem or whatever…because they want to identify GOOD parts and weed out the bad. not just kill everything.

    @hondageek08 it hurts to be a moron eh. Your stock block has ductile sleeves. go suck a dick.

    what do you do to fix this? bore the cylinders?

  14. akracer1 Says:

    Put it back together and get it hot and put some some stop leak or black pepper in it.
    Better yet just fill the block with block filler above the pin holes and your good to go.
    If it’s a race motor, it should be filled anyway.

    It is due the air presure hose connected to the head. The air makes the detergent goes down the cylinder and in a leak it produces somehow bubbles.

  16. YoungJim409 Says:

    You could, sure, but leak testing with soapy water is probably a lot faster. (Provided you already had deck plates)

  17. Relik3343 Says:

    they use soapy water and air… not to see the leak thats where the soap comes in it will bubble on a leak.

    all in the name of speed i guess, ive worked on a few sprint car engines where customers were so concerned about weight they cut fuel pump mounting bosses, oil filter mounting locations(only on dry sump engines though), and motor mounts bosses etc… all in the name of speed.

  19. 1986z28owner Says:

    They use pressurized air to fill the coolant jacket in the block, and the soapy water will form bubbles on any surface sprayed if a leak it present

  20. Frylok1177 Says:

    The reason to polish anything is to relieve any pressure points and smooths everything out so oil just flows right back down to the cam and provides maximum oil flow to the cam.Smart thing to do.

  21. demonxanthwataru Says:

    You can tell if there’s a leak because the soapy water foams up as the air goes through it. Tire shops and gas pipe fitters do the same thing. It’s really a very clean, fast, simple, and cheap way to find an air leak.

  22. orsalexis Says:

    i can’t understand how you can tell if there is a leak… :(

  23. thugathugacation Says:

    I found it pretty amusing he polished the valley hahaha. I guess you can sleeve this block, just another reason to go faster!

  24. digzie1 Says:

    why am i the reason, what happens
    when some kid is looking 20 years
    from now and can not find one because
