Challenge: Engine Diagnosis

[Celestialsailor]

Thanx for the tip. I did take th end caps off, cleaned the surface and did make a hi heat gasket for it. I have only put 30 hours on the engine since the rebuild. lets keep our fingers crossed...

Here's a little tip. Always take the engine out of gear and rev it high just before shutting it down. Cleans out the carbon every time

I have never heard of that but this guy's been a builder for almost 50 years.

IF you follow this advice, you should squirt the oil AFTER the air filter not before it.

That is one sweet looking engine!

Here to report the engine is still doing fine. About 60+ hours on the rebuild. I'm tearing into the in hull diesel tank this week and polishing the diesel. By the way Miniyot...No air filter on a diesel.

There should be a air filter on a diesel, dirty unfiltered air will cause wear on the piston rings. Result is loss of compression & increased oil consumption.

My Volvo 2003 never had one,
My Westerbeke 4-107 neither
The Yanmar 4JH didn't
Perkins M-40...nope
This Westerbeke W46...Uh uh
They all had a screen that would keep flies out but not mosquitoes.

Maybe up a river! Out at sea the air is clean, unless it's a really dusty boat.
My Yanny only has an air box.

Yup...thats what I meant by screen...was the air box with a very course mesh screen.

Don't know for sure. Haven't had it off yet.

I like the uni-joint on the trans. Looks like that ran you a few house payments.

The Pythondrive was a little over 1 boat credit and I had to move the motor forward about 3". Plus had to build a mount that would take the force of the prop/shaft pushing the boat. But it runs real smooth and keeps the PSS on center with that dancing yanny.

Wunderbar!!!

Dell's motor is so pretty that it lives under a see thru cover and he uses it to pick up women!

I do have a peep hole. But yeah! It's a real chic magnet. I have the wife scrubbing it with a toothbrush every saturday.

There are farms on both sides with fields that get plowed & the wind then blows dust everywhere. I have K&N filters on my Hinos & Westerbeke gen to keep that dust out. IMHO unless the air is hospital clean a engine needs a air cleaner. I've heard of dust blowing across the ocean from the African continent, may be at high altitudes & not a problem to sailboats. To each his own, a diesel breaths thousands of gallon of air for each gallon of fuel & I'll try to keep mine clean because dirt is the enemy.
