    One piece oil pan gasket - OS30612T ?

    Is this the correct gasket for my 87 Shelby Lancer ? Just wanted to verify before spending $40 on a gasket I can't use

    EDIT: I think I posted this in the wrong section.. I thought this was the tech section lol.

    I'm pretty sure the 1 piece only works for the common block pans. Yours is an earlier one. You are stuck with using the rubber end pieces and RTV for the rails.

    What can I look for to verify it is the earlier block ? Or is it not possible to swap in a common block ?
    I just want to be sure no one swapped in a later block at some point. I'm on my phone and not having much luck with google.



    Thanks,

    If its the original motor its non commonblock and will have a fuel pump block off plate to the left of the oil filter above the alternator in that area. 89+ motors are commonblock.

    Is the crank gear pressed on or bolted on? Square timing belt?

    Look at the oil pan shape… The Common block has a half round shape on the front end, rounded off square on the rear end. The early block is the same rounded off square shape on both ends.

    I always found it hard to tell unless they were side by side, lol.

    The CB also has a small 6mm bolt at the front by the oil filter.
