Re: FX Holden Race Car Project
Glad I've only had to deal with one piece seals, so much easier.

Re: FX Holden Race Car Project
Theres bugger all Neo rear seal 202s around from factory, im hoping atleast one of mine are,
somehow my 308 with a rope seal doesnt leak, since its on its 2nd crankshaft, with the same rope seal, never leaves a drop of oil on the ground in the last 3yrs

why have one 202, when you can have 12 and counting, 30+ car graveyard just for fun aswell

like i said i havent run it for long, but literally not a drop has come out so far, and when i ran it before it was leaking almost as soon as it started.

Re: FX Holden Race Car Project
Didn't the 202 go back to rope seals?

Re: FX Holden Race Car Project
yeah the later model blue/black motors are rope.
In other news, last night dad and I started on the window cut out, so we managed to get the front window mostly cut out, it needs some trimming on the edges but we chose to go on the larger side for the first one to make sure!
Its obviously sitting lower than where it should be but i couldnt get it to stay up and hold the camera at the same time!
we've also made a template for the side windows and started on the back one, as it got too late to make too much noise, but its moving forward at a good rate
i need to try and decide on a method to attach them, i have a few ideas but nothing locked in yet.

Re: FX Holden Race Car Project
Apparently the trick with neo seals is to offset the joints a little from the block/cap mating surface.
I did a rope rear main in a 3.3 many moons ago, never done one before and it didn't leak, must have been pure luck? Soak, fit, trim?
Looking good 202, can't wait for the first driving video

Hiya,
I learned about flange sealants many moons ago and I used to use some Ford flange sealant on the ever leaking early 2 piece SBC's once you put a bigger pump on and had more clearance for RPM. When I couldn't seem to get the Ford stuff anymore, I used one of the Loctite variants. I think the 510 was the same as the Ford stuff and the 518 was too thin. I'll check at the shop tomorrow. This strategy completely ended my circle track engines having that small amount of fluid leaking from the rear main. Oh, just to be clear, this doesn't eliminate the seal, just used as a sealer to help the mating surface of the seal to block and a thin swipe at the parting lines where you could offset if you like.

Re: FX Holden Race Car Project
I used that stuff under the bolt heads on the sump bolts on my VR along with aviation sealant (the brown goo) on the rubber gasket. 7 years on and its not even weeping.
