Re: Yanmar still overheating

If you are going to drain the coolant then you should remove the heat exchanger core and check it. It is not hard to do especially if the coolant is already drained.

Re: Yanmar still overheating

I had the same problem on my engine. First, check to see if your water manifold was recalled. See previous post on this one. Mine was and Yanmar changed it out free. The grey smoke can be caused by a plugged up exhaust elbow. The 3YM30 engines Yanmar recommends every 250 hours to clean it out or replace it.
Take off the hose and shine a light up the elbow to see if it is plugged. If so take off the 4 bolts that hold the whole unit on. You will not be able to unscrew the elbow from the adapter while on the boat. Go the easy route. Either get it cleaned or replace it.

Agreed but will I be able to save the gasket or should I order one new before removing heat exchanger.??

Not sure about yours but on my 4jh2e the gasket is simply a reusable O-ring. Order new as you should have some spares on hand anyway.

Re: Yanmar still overheating

Finally was able to work on engine yesterday
Found oil in the bilge ! Dipstick showed half empty But was full last week when we started our trip
Refilled and started the engine . I have a mist of oil coming out of engine !
Right about 2 inches after the oil filter and below the fuel pump At first looked like I was missing a bolt on the engine block No kidding !
Then found this part in the bilge

Fits right in, and stops the oil leak but what is it ? Its a plastic plug with a small metal tube inserted Could be that I am still missing a piece ?
It is not a sender or pressure sensor Nothing can be connected to it
Could it be a pressure overflow ? Then I would be probably missing a plastic tube on top that would guide overflow of oil into the bilge

I emailed the pict to Yanmar but yet no answers Local parts dealer has no clue

Scratching my head

Re: Yanmar still overheating

Is your engine a sail drive version?

Re: Yanmar still overheating

Dip stick plug, there are different models with the dipstick in a different location and that hole is not used and plugged. although your piece looks more like a cut off dipstick. is the piece in the center solid or hollow tube
