Skimming Exhaust Manifold

Post by **wookey** » 06 Apr 2007, 14:36

I've found the exhaust manifold is corroded on no 4 port. causing a leak even with a fresh gasket.

So how much can I get skimmed off the face of the manifold. Looks like I need to cut about 2mm off it so that it seals correctly on the block again.. failing this.. anyone got a N/A diesel exhaust manifold.?? (wanted add posted just in case! )

use some firegum or exhaust paste,, that'll seal it

yes they can be re faced, any engineering place should do it for you in a couple of minutes.

so now its off do i paste it up? i suspect this would only be tempory due to pressures at the exhuast port? or wait till next week and get it refaced.. would i gain the much more? cheers

Get it refaced if you want it too last.

take it to an engineering company, but most of the cost will be setting up, and as andy says its not a big job, probably only take 10 mins but setup would take twice that long. Any problems give us a shout.

if indeed it only needs 2mm off i would paste it (thats what the paste is designed for) and the pressure in there is not high as in like a head gasket cos its kinda blowing to an open end
