    Will be swapping in a built 99 Cobra engine.

    On a centri and turbo setup pcv is forgotten by most. From idle to 3000rpm the car is N/A and vacuum is present . Above 3000 your making boost through the intake and with a stock Marauder pcv valve (which isn't intended for boost) it will allow the boost pressure to enter the PS cam cover.



    The post Blazed71 put up is good but I would make a few changes to it as newer and better parts are now available.



    1) no need to gut the OEM pcv or swap the inlet for the pcv location to the DS cam cover. (03 cobras have a push in pcv valve)

    )2 Get a pcv valve for a 2008-2010 GT500 it will screw into the stock location no problem with one exception. Its too tall. So cut it down to length with a hack saw

    3)add a one way check valve at the stock location on the intake (yes you can keep your catch can if that's what you want to call it )



    This setup will yield a cleaner look and will out perform Embassy's old setup. If you want to get fancy you could get a wiring pig tail and wire the heater element for fun. The Gt500 pcv has one built in



    I have no doubts you were sending boost into the engine as you have presented it.



    Research the 8 rib swap, and if a 3 bolt cover isn't in your future at least get a single bolt thumprr tensioner.. They're expensive but well worth it!!



    Sorry for the interruptions...… Please carry on……..


    No need to apologize. I welcome any help I can get. I’ll look into getting the parts this week. If you will, provide some more detail on the size of check valve and if I read correctly, the GT500 pcv will go in place of the driver side valve.

    There’s two listed on rockauto. Which or does it matter?

    order the blue Motorcraft.

    Mods needed on the pcv valve: With a dremmel narrow down the plastic ring on the neck of the pcv valve. Use the stock 90* off the OEM Marauder pcv as a test to how much material to remove please remember to use a heat gun to warm the OEM 90* and get a tight fit. once the OEM 90* slips over the ring cut it down to OEM length with a hack saw.

    As far as a check valve 5/8" is the diameter: order 2 of these one for each side
    https://www.ebay.com/i/291327163877?chn=ps

    So from the PS cam cover it will go as follows:
    GT500 pcv valve - JLT catch can - one way check valve - upper intake

    DS will have a check valve and a feed from the SC

    Will be swapping in a built 99 Cobra engine.

    I have two simple questions I’d think.

    1) where in the h*ll does the ground strap from the back of the engine tie down on the firewall? My buddy helped me remove the engine so I didn’t remove it myself

    2) there’s a bracket that holds the starter cable in order to route it back up into the engine bay. It has a stud on it, what should be terminated on that stud?

    So close to startup. Got everything else in place, just trying to decide on what to do with the exhaust.

    Thanks for posting that pic. Believe it or not, I was standing there looking at the engine bay and saw where I had a small bolt threaded in a hole in that location and I was like, “it can’t be!” This is the first time I’ve ever had the wiper cowl off so I wasn’t sure if that was for the cowl or what. Right now that’s about where I have it located. I’ll take a pic tomorrow.

    Hey Marty,

    Do you need me to tell you where to put it?

    Oh Lord, I wonder what this one will cost me?

    Look at the arrows on the check valves to verify they are functioning as designed
    PCV side: the arrow should point towards the intake
    DS: arrow should point towards the engine

    If you set them correctly once you get into boost the PCV side will draw closed (preventing boost from entering the engine).

    The GT500 PCV valve will catch anything that gets past the check valve. (fail safe)

    The DS check valve will stop any oil blown from the engine from entering into the CAI track

    The system is correct and should perform well.....

    BTW your cooling mod hose is too long.
