If the block and head check out ok, rebuild both - then you will know what you have. Getting a second hand engine is a crapshoot. Could be as good as what you already have. Parts are readily available for these engine. When built properly, you would not have to touch it again. |

Thanks for all the advice guys!
I'm a gunsmith by trade, and tinker with other stuff on the side. I have a vertical mill and lathe in the shop, and my wife's uncle owns a machine shop. He and I have discussed what to do. So here's where I am headed...you tell me if you think I'm crazy.... I've ordered and received a new piston, connecting rod, and sleeve, along with gaskets. I also ordered a valve train overhaul kit. Currently the head is on the mill. I'm going to go ahead and "face" the head. This "should" help find any visible cracks. Next, it will be off to his shop to check for cracks in the head. All in all, the head doesn't look THAT bad. Is there damage, yes. But I think the fact that I didn't keep forcing the motor, it prevented a lot of further damage. I've pulled the caps off the other connecting rods, and all the bearings look perfect. There's really no other metal pieces from the sleeve in the motor. I'm going to soak it with oil, and let it drain again through a coffee filter, just to be sure. I think I can salvage this. Maybe I'm being optimistic, but it's not as bad as what I originally thought. Just going to cost me money and time! Thanks again for all your input! This is a great forum to belong to...everyone has been very kind and very helpful! Brett Havlin Brownsburg, Indiana |

I'll second Steve's description of the failure... with one exception:
The valve broke, and bounced around in the chamber... piston found it several times, and bent the rod. THEN... the bent rod, with piston cock-eyed in the bore, shattered the sleeve, which then ventilated the coolant. With a broken sleeve and a missing valve, no substantial hydrostatic locking would occur, but it'd make quite a white cloud overhead. If it were me, I'd check the crank for damage (cracks and twist), then the block in every area near the sleeve for damage in webbing and seal faces. If it looks clean, put the lower end back together with a replacement piston and sleeve, rod, wrist pin, and rings. Milling the head... yeah, if there's a crack, that might help discover it... Fortunately, that's really good malleable iron, so it's not gonna shatter like a lesser grade casting would. It's a no-worries job... don't overthink it, don't sweat it, just dig in, make somethin' happen, and have faith and fun. For what it's worth, I've got one engine that when I was lookin' in, I noticed it had one sleeve and piston that were smaller than the rest... it obviously had a problem, and someone substituted with whatever they had from some other wreck... and it ran wonderfully, so I left it alone. |

I got a con rod outta a 283 Chevy that looks like that. Broke ex valve @5800rpm one night.Destroyed piston and busted cyl wall. Valve head was stuck in piston head sideways. Made me believe in always replacing ex valves on rebuilds.

Do not worry about any spark plug hole cracks. They don't hurt anything. Also, if the head surface isn't quite perfect, it too won't hurt a thing. You're the only one that will ever know.

Couldn't find my valve spring compressor, so I improvised....

Weather is nice here in Indiana. Has been in the upper 40s, low 50s...in January!
Has given me the opportunity to get back to work on the D14! Today I got the block all cleaned out and up. Got all the metal out of it from the sleeve that let go. Installed the new sleeve, and new piston. Got the connecting rod on the crank and everything torqued down. I'm hoping (fingers crossed, rabbits foot in my pocket, four leaf clover in my wallet) I'll have this back up and running this week! |

Head is back on! I'm going to try and get the push rods and rocker on. Hopefully set the valves today as well.
Question, though, how does one hand crank a d14? There's really no spot to put a wrench to turn it. Am I missing something? |

engage PTO, put pipe wrench on PTO shaft
REMOVE pipe wrench BEFORE starting !!! do NOT ask WHY I KNOW this.... other option is to put a big ,bent screwdriver in the timing hole and move the ringgear,just be careful.... this is closer and since no plugs in holes is easy enough to do. Jay Edited by jaybmiller - 30 Jan 2018 at 6:44am |

Isn't there a hole under front grill screen for a crank to slip in? If so, and the crank pulley is right then a C Allis crank should grab the crank pulley to turn it over.

There is, but I don't want to chance buying a tool that may or may not work. I think the pto trick is the way to go!!! Thanks guys! |

Just take your key out and tie it to the pipe wrench. (Assuming you have a key, that is... )

Another question....
What tools have you used to get the two bolts on the oil pan, closest to the bell housing? I've used a wrench, but I can only move it a smidgeon each time before resetting. Tite reach? Some tool I've never heard of? |

Using the machine tool to install the valve springs seems like a logical thing to do. I once used a jack used to lift war heads onto air defense missiles to install an engine in my VW bus. Inspector later asked the crew where the dirty engine oil on the jack came from.......

Today I had my 9 year old son in the garage helping me put the D14 back together. We got the push rods, rocker arms, valve cover, and thermostat and housing all back on. He was excited to help, and was awesome at helping set the initial tappet gap.
Next on the agenda is the pick up, oil pan, and putting fluids back in. To say I'm nervous, is an under statement. But, that's we learn, right? Spending time with the oldest boy, and teaching him a little something is worth it. |
