  • leaking cam box...upgrade options?

    there's a oil leak and the mechanic says it's the seal between the cam box and head. i'm not really ready budget wise to rebuild the motor yet but it is something i plan to do. what can i upgrade while i'm in there?

    i'm thinking:
    284/276 cams
    VAC stg2 head

    i also have a set of rally header coming so that's gonna go in as well.

    i'll probably do the 2.5L bottom end about 9 month~1year from now. is anything else i can do right now without spending much more money/time in labor

    one more quick Q. will i need to do engine management at the same time or can i just drop in the cams, swap the head, etc.

    thanks again!!

      There is no "seal" between them; just contact between the two machined surfaces. If the leak is in between the cam box and the head, why not just remove the cam box, clean up the surfaces and assemble with Yamabond?

      Doing cams will require a new chip...also, non-OE cams like the schricks you mention will require adjustable cam gears and lots of time spent on degreeing the cams to the factory pistons. There are better ways to spend money than doing that job with the engine in the car.

      Personally, I'd do any upgrades at the same time the 2.5 project is being done to save time/money and do it right.
