Exhaust Leak at Turbo exhaust pipe connection - What am I dealing with?

[MikeP]

Congrats, you done good!

In the worst case, if the sealant proves not to be as effective as the MTU stuff, you now know how it all comes apart/goes together and can easily re do it. IMO, the knowledge gained by doing the work, as opposed to having some mechanic do the work is well worth it even IF you have to re do it.

Whats to say you learn enough to get it right the second or third time?

I am sure it will be fine with that temp rating. Looks like a first class repair.

Looks good.

Check the cooler and airbox though, if you haven't already.

Thanks,

I intend to check the intercooler and the airbox, but do not have the intercooler gaskets yet and agreed to take our youngest daughter and several of her friends out to the island this afternoon while she is on break from PT school. I did not want to get into more than I finish before then.

I assume it will be safe to run for a couple of hours at less than 1200 rpm.

I did not feel comfortable with the size of the turbo blanket that I bought on ebay and discovered Applegate Industrial Materials: http://www.the-flex.com/contact.html They are a commercial marine supplier located in nearby Baton Rogue LA which sounds good to me. I learned of them looking through one of Dave Gerr's books, "Boat Mechanical Systems Handbook" which contained an number of photos of boat exhaust insulation products with credits to Applegate.

I called them this morning and the owner, Bob Applegate answered the phone. He was very helpful and quoted $185 for a turbo blanket and $40 for a cover over the turbo/connector flange. Sounded reasonable to me.

Thanks also for the reassurance on DIY. After spending a weekend working on the boat and explaining to my wife why I didn't spend it with her I have to remind myself why I do this vs working more at the office and paying a professional to work on the boat. Long ago when I worked summers on commercial fishing boats as a deckhand / engineer, I appreciated the need to be able to fix things which broke while you were away from the dock and would not get home unless you could. Plus, I enjoy working on the boat.

Yeah you'll be fine to run it to do what you intend....

I've used DeAngelo Marine Exhaust in Florida for turbo blankets -- good stuff. They also were able to fabricate a crossover pipe ("collector") set for me when my original ones rotted out.... (that wasn't cheap though!)

Friday's trip to the island went fine, 50% chance of rain, but we received the sunshine half and had the island to ourselves.

No problem with the engine or its exhaust connection, it worked just fine.
Wish I could say the same for the aft head, the Raritan Atlantes uses fresh water and for some reason it would not stop pumping water into the bowl and it soaked the aft cabin carpet.

Hope to talk to Raritan customer service in the am.

Take the freshwater solenoid valve apart. Just loosen the four bolts on and pull apart. There is a rubber diaphragm in there and even a single grain of sand can keep it from sealing. I have cleaned one of mine several times. The last time it still kept running water so I bought a rebuild kit for it. That fixed it. It is not a Raritan part. If you get the valve number, you can get the rebuild kit online.
