Heater pipe O rings

[maldotcom2]

Where do you guys buy the O rings that go on the heater pipes which lead to the lower intake manifold on the ecotec? Mine seem to need replacing every time I pull the thing apart. Do we just have to go into holden spare parts and bend over every time?

Just use some blue rtv. Mine hasnt leaked since. And for a tube cheaper then the o ring, can you go wrong?

I've tried the black RTV, that didnt last 5 seconds. I might just have to get the genuine ones and then order a bunch of them from a rubber manufacturer for the inevitable next time(s).

I went through this last weekend. I bought a VRS gasket kit because I needed to change my inlet manifold gaskets. The smaller heater pipe O ring in the gasket kit would not seal, it kept rolling off as I pushed the pipe in. It was thicker than the genuine one I ended up getting.

Anyway, the bloke at the Holden Spares place told me that the orange coating on the genuine O ring melts to help form a seal. He said this is probably why they are so expensive. So it may not be a good idea to just buy a bunch of O rings from just anywhere.

For it to work, and i have blue rtv on it, drain it, seal it, let it dry over night, then add water.

i just used a cheap o ring i got in a pack or 50 from cheap discount stores, and a little blue sealant, not a drop and ive done it to 3 vs/vt's and its been a couple years

Why do you keep pulling it apart?
I got them both for $15 from holden when I did my manifold gaskets.

I was told the genuine O rings had a flat edge?

The other one is 24502846. Just ordered both of them. I figured for the sake of 12 bucks I dont want to risk the RTV blowing out and dumping the coolant.

Thanks for that.
