23 on course - Harley Davidson sound

[robert mueller]

Espen,

Peer did not investigate his exhaust leak, it could be:

1) the donut
2) the exhaust manifold to head gasket
3) the gasket under the choke stove
4) a cracked exhaust manifold
5) etc, etc, etc

Just thinking here, if you have a Harley sound could it not be one of the exhaust manifold gaskets ? I do rarely see a dunut failure on the GMC but a
lot of blown manifold gaskets..

Peer,

I thought the GMC with the exhaust leak is on a boat to Europe?

Morning,

coach has been upon the lift.

The exhaust manifold has a leak. I might already have a source for a
pair of exhaust manifolds, but wonder what the right gasket is:

455 is the engine.

And do I always need a new gasket, even when Ken Frey replaced both
gaskets 4 month ago? /me thinks yes.

You don’t always need a new gasket.
If the gasket looks OK (no tears or breakouts or burnouts) I would suggest that you coat it both sides with Permatex Ultra Copper RTV and replace it.
Torque it to the proper value — its in the maintenance manual.

It is important to retorque a manifold a hundred or so miles after installing it.
That might be why you have a leak.

As to new gaskets most of us are now using Remflex gaskets. RF11-001 is the one for Headers RF11-003 is the one for stock manifolds

Thanks for the details. I guess, I better order the gaskets. Better safe
than sorry when I do need them.

I'll try my luck with some Fire Seal cement first, as I am in a bit of a
hurry, and won't get the manifolds in time. Maybe it helps better than
expected.

Remflex, with the divider in the center port. Follow the instructions.
