    Default Experiences with Felpro "Low Drag" rope rear main seal

    I've finally pulled my finger out of my butt and got all the bits together for my 355. The heads are one of the early head sets HPE Pete did in a Sticky.

    Blocks been machined and painted and I searched for ACL rope rear main seals but can't track any down so purchased from Flea Bay a set of Felpro "Low Drag" versions.

    Received them yesterday and man are they soft and flimsy, these are ZERO drag !!! Has anyone used them with success as I've never used them before and would be pissed if it leaked.

    Otherwise does anyone know of a brand other than ACL (unless they're still available) that has worked for them?

    Has been a while since an engine build thread's been posted, may start one.

    .. never had aftermarket rope seals work, they all leaked
    In my experience only the genuine holden ones have worked


    and as they are as rare as rocking horse doodoos these days, I now use the FELPRO Neo style seal

    I used the Felpro neo seal and left the knurling there.
    Coming up to 3 years now without a leak.

    I use rope seals for most engines that won't turn past 6500rpm, done right they won't leak, after break in there is sfa drag, they will outlast a lip seal by a good margin & they won't wear a groove in the crank.
    Doing then right is the trick tho, I must have fitted several hundred by now & got them down pat.
    I just use the plain old permaseal ones, I reckon they are all made in the same factory anyway - all look the same.

    I'll use a lip seal on a hard turning motor, rope seals can burn at high rpm, so no good if it's gonna spin to 7k pretty often.
