Well guys, you know me, I never get in a rush about anything, BUT I knew you guys  :smilewink:  wanted an answer for the crankcase breather question & I have it.  It DOES vent into the intake, via inside the valve cover.  I'll get a pic later.

Just hit me, but with the crankcase vented to the intake, that would explain some of the catastrophic engine losses.  If anything went wrong with a ring to where lots of excess oil was forced out with blowby, a "runaway engine" would almost certainly happen.  There is nothing to stop it in that situation.

  Makes me wonder if I should make a new breather cap to bolt on in place of the diaphragm that vents to the atmosphere.

You may be blazing a new source of diesels for GTs. If there are a bunch of these diesels out there for cheap and you figure out how to improve their reliability. Thanks for being the pioneer. Good Luck, Rick

13.7hp @ 3,600rpm

I imagine the torque goes well beyond a similar gas engine?

You betchya!  At least they sure feel like it.  I looked up a Briggs 14hp twin & actually they call for almost identical figures, but as with my 16hp Yanmar in my Massey 1655D, there is no comparison in real life power when comparing to say a 16hp Onan gas twin.

Would you part with one of these? I am in the process of figuring out what my ultimate goal with the GT's I have is! A diesel would be a good addition for what I have in mind!

It will be a while before any of these would be ready.  I won't sell anything that I don't think is ready & reliable.  My idea was to keep one & sell at least one more.  TD&H already spoke up if I let one go. Just have to see how they shake out.

That's cool with me, Daniel!

Here's the valve/intake cover.  The lower part in the pic is the valve/crankcase area.  The vapors go into those tower like areas, then pass through the diaphragm & into the intake on the upper side.  Note the hole right in the center bottom of the upper half, which is the intake zone.

I used my 1655's FEL to pull the 2nd unit out so I could place it in the shade.  Unfortunately I couldn't crank it over, as the starter needs work.  Another day....I'm tired & need a shower & a bit of rest.

one of the worst things I hated about this engine was it took forever to get the oil down to the pan so you could see the level when servicing. sometimes you had to wait half an hour. must have something to do with the baffling inside.

That's interesting. No intake manifold per say. Thanks for answering that question.

Just took the non working starter off.  Works fine as wine now, so must have been a bad connection, as sometimes even the solenoid wouldn't kick in or even make any spark. Once off & jumpered, she kicks in strong.  I'll likely take the starter apart, clean/inspect, then do any needed repairs to make it 100% before putting back on.  I can certainly understand Jeff's frustrations working on this brand APU.  Dang sure wasn't put together to be user-friendly, near impossible to get to anything!

After such a short time dealing with the difficulty of accessing components on this brand of APU, I think I've figured out why so many fail...........sabotage!   The service guys figure if they "help" destroy enough of them, the trucking company would switch to another make APU!  :smilewink:   Just kidding Jeff, but they are hard to work on!
