Leaky BMC. question

[Andy C]

My buddy's bmc is leaking between the booster and the bmc. i know theres not a gasket between there. So does he need to replace it? its torqued down all the way.

[Neejay]

Yes, there should be no fluid leaking from it...even if it was not bolted down and just dangling there.

You're talking about in between the BB and the BMC where the 2 nuts are the only things that bolt it up?

[Andy C]

yep. its leakin from there

A leak is a Leak

The bolts do nothing but hold the cylinder to the booster.

So, it needs to be replaced.

The rear seal on the BMC is what's leaking. There generally is a gasket there but its only to keep dust out of the booster/BMC, it there is fluid there the BMC is bad.
