Re: manifolds and risers

Howdy,

It depends on a few things.

1. Fresh or salt water?

2. When were they changed before?

3. Have you EVER seen inside the riser/manifold water jackets? (I.E. have you removed the risers to inspect the condition of the sealing surfaces AND replaced the riser gaskets?)

You don't of course wait until they fail..... That could cost you a new engine.

Here's a great bit of info on the question.....

Re: manifolds and risers

Best bet is to have them removed and inspected....at least that's what my mechanic said

PS. Good article Rick!
