O-ringing the vg30e block for…


  • O-ringing the vg30e block for…

    Well I am looking through summitracing and noticed that the metal head gaskets require o-ringing the block. What exactly does this do and how much can it cost typically?

    Puts a stainless steel ring around each cylinder bore that sticks up past the deck of the block. When you put the head on it creates a mechanical lock on the head gasket. When I had mine done, it cost me $230 to have the stainless rings installed. Looks like a wire around each bore.

    I assume you are looking at copper gaskets since they require a ring?

    Summit also sells ones that are copper but, do not require o-ring.

    They require a gasket glue or something along that route!

    Get Jason's gaskets!!!

    Well the head gaskets I was checking out were the summit racing ones and they state o-ringing the block is required. Thanks everyone for the help so far.

    I ran these type of gaskets on my 3vzfe camry engine and problem always was with the coolant leaking under high boost hope you have better luck . I had a custom batch made by Cometic and that was bullet proof.

    Everyone I know who uses copper seems to have coolant weeping / leakage sooner or later - they are designed for drag cars that get taken apart all the time… don't run copper unless you're OK with that. This is still true if you have the block O-ringed, as it leaks from the coolant ports.

    Jason does have the MLS gaskets - I bought a set from him for my 3.3 build - they appear to be decent quality, I wouldn't say as nice as my old HKS MSL gaskets, but then again they are the best option we seem to have at this point.
    '84 AE Z31 - last time it was dyno'd - 392RWHP, 431 Ft-Lb RWTQ.

    For this year - building a VG33, bigger turbo (GT35R BB), just got done with making my own custom roll cage, all of the bodywork and a new paint job!

    Alright then, now we just need to have every hole on the block o-ringed then! I'm sure that will be cheap!

    Ehh… just plug 'em. Who needs coolant and oil anyway? :nanan?re
