exhaust manifold temperature

[srokag44]

One of my exhaust manifolds is running much hotter than the other. Is it safe to connect a garden hose where I put the arrow in the picture to flush the exhaust and riser? Is it ok to do this without the engine running or is there a risk of water getting into the exhaust ports?

DON"T DO IT. You are correct, there is a risk of water ingestion. Better to remove the manifold if you want to try flushing it.

And water won't do it . I like using rydlymemarine

Hey prowlersfish , how would you use it in exhaust manifold . Om my 318 starboard side experiancing same thing , running bit warmer then port side . I figured maybe there was nest in there as did find some straw tail end .

You have to rig a way to recirculate it . Its a lot safer then many acids . but still us caution .
