Sealing air intake glue type.

[andytop25]

Hi there
Some time ago I've bought turbocharged petrol Merc. It goes well however after some lively driving air intake inlet/charge duct pipe elbow ( where is connected to inlet manifold) broke. I have sourced new parts but realised that it's all put together with some black oil resistant sticky. Did try to get info from turbo conversion company but have no answer. What stuff is usually used in such applications?

I'd expect to see either a permanent manufactured bonded joint, or a clamped joint. I wouldn't expect to see any goop/tacky adhesive anywhere. Is it possible this was added later in a bodged attempt to fix a leak?

Based on the fact that the hose to the waste gate (I assume) is bodged together & the inlet tubing/couplings doesn't look standard or like it fits together too well that is highly likely.

Thanks for sharing. As you see in picture intake pipe is alloy all the way till MAF sensor housing, then that part is standard (plastic) plus plastic elbow where connected to manifold. Joint between metal and plastic is sealed with some sort black mastic that gone hard. My thought is that some special sealant was used. I'm in a building trade and seen few types but not familiar with automotive types. Any ideas.
Whole turbocharging was done by quite decent specialist.
Cheers for help.

Perhaps they used Sikaflex or similar, although it doesn't sound like a good solution to me.

Who says they are a decent specialist, them by any chance? The whole install looks rather amateur to me.

Have a look at the Hylomar website, they might do something you could use.
