Leaking 3B IM

[s2driveruk]

anyone previously come across this when tracing boost leaks. Appears mine is leaking through the actual IM itself in two places at the very end nearest the slam panel....1 on the edge of the moulding mark where there is space the the PS pump to move up towards it Ylooks like a bolt shaped indent and the 2nd on the 2nd side of the runner. Really wierd that its now porous and bleeding off a significant amount of pressure. I have patched it for the moment with some epoxy/liquid metal stuff but its more vorsprung durch bodge that i would like. what options other than replacement exist???

Short of some exotic welding I dunno what else to suggest. Would probably be cheaper to source another IM than a good long lasting repair.

JB Weld will cure and set and will seal all the leaks however now would be a good time to go to a reverse inlet manifold

[S2central.net]

I was thinking jb weld too but you would need to open up the cracks sufficiently large to have any chance of the wonder product taking hold. It might be worth a try if a replacement IM is hard to find.

True true, not a lot of IM on the market at the moment a lot of them have been bought by golf owners and chopped up!

Could be worth a cheeky upgrade to ABY IM

Must be some of those castoff from the Wagner Reverse IM users ??????????

Isn't there some silly difference between the 3B and ABY? IIRC, Newsh had some problem with different dimensions when fitting the RS2 IM. Worth a search fo sho.

[Jamo]

Yes the ABY and RS2 ones aren't designed to fit over the dizzy and you have to modify them to do so

For Newsh IIRC he had to make a spacer for the throttle body as well

For sure, that sounds like the one. Family album has ABY and 3B TBs as different suffixes. David, I have a spare ABY TB, should you need to borrow one

[S2central.net]

Oh yeah... that confounded dissy.......

SO maybe a chance for a cheeky upgrade to ABY IM, coilpacks, wire swaps, ECU, fuel rail & CMP - LOL

:lol i sniff some scope creep on this one

This might sound cowboyish , but seems the in thing at the moment take it off and send to get ceramic coated , I know it is meant for more heat induced items but cant see why not it would not work ?..wont leak again after that , guy down the road does them for £120

Good alternative but probably more than a replacement 3b im would cost if one could be sourced. Even changing everything to aan reverse inlet setup would not be much more than that amount if you get the stuff from the right forum members.
