View Full Version : Exhaust manifold

Just found out my RAM failed it's MOT on leaking exhaust on LH and RH manifolds.

Having not seen the car (and no technician having looked at it) I am guessing that the gaskets have gone.

Would I be getting in to all kinds of trouble if I looked at replacing these myself - are they likely to be custom. I've done work on engines before but not at this level and not having a Haynes to follow I'm not sure what it might entail.

I'm running a Chevy 350 if that makes a difference to anyone!

if you don't fancy doing this yourself go to Maniflow in Salisbury they may help

Is Maniflow the same as Janspeed?

If so, that's where it is at now

That's a p1ss easy job to do yourself....don't be frightened. If you cannot get a set of new gaskets ( a set of Fel-Pro from Real Steel, part no. BY 1404 FP are superb)then get some RTV high temp silicone sealant, pop the headers of, quick squirt of sealant and bingo....done?

Sadly it's not the gaskets as suggested by the receptionist!

When I took a look under the bonnet just now, the test house guy had removed some of the lagging around the front exhaust section to reveal a massive crack where the sections from cylinders 1 and 4 are welded together.

That's not a job for me! Have left it with Janspeed (who are exhaust specialists) to see if they can do a weld job on it - else it's quotes for new ones.

Maybe this is the excuse I need to convert to side pipes!!

Cheers for you advise. I may come back for pointers on recommended companies for custom exhausts if things look bleak tomorrow.
