Did anyone use this http://www.atomic4.com/crankcase.html ? Does it help to eliminate crankcase smoke?

I have one and it does - assuming that is where it comes from.

If your exhaust is dripping water, chances are that it is corroded nearly all the way through, and is just waiting to fail catastrophically at the most inopportune moment. Since you can't effectively repair it, be proactive and rebuild the exhaust now. Unless its built from stainless, heat and saltwater mean that 5 years is about all you can expect from one.

Use black iron pipe from the Hardware store (DON'T use galvanized! Its toxic!!) and wrap it in thermal tape, sold here by our host.

Here's a link to the rebuild I did in stainless:

Its now in its 10th year with no leakage.

My parts from Moyers are on their way and I've already purchased pipes and fittings for the new hot section. I also got an exhaust hose with 1 1/4 inch internal diameter but it looks like it won't fit. The barbed end of the brass fitting with the water inlet will be more like 1 1/2. What hose diameter should I buy?
Maybe it does fit and I just need to heat it up.

Both the Moyer water injection fitting and 1¼" pipe fits 1 5/8" I.D. hose.

Thanks. It's tricky to find that size here...
