It does look like a cracked bore but any good machine shop will be able to bore it out and put a sleve in .PS in Canberra best engine guy Greame Silk if you can get a booking if not go to Greg Tarlington at Pro Engines 18 Stephens Rd Queanbeyan as he likes to do one off's and i can vouch for his work very good. :)

That's the very early round base water pump, not very common at all and still specific to the 6.9. 6.3 pumps are similar, but cast iron. I'm sure it can still be rebuilt if required.

It looks quite decent to me. The marks in the second pic are from water/coolant ingress, by the look of things. As for the mark in the vertical plane, it may well be a hairline crack, but hopefully not. I would imagine that could be checked out by a well equipped specialist.

The excess wear in the first pic isn't spectacular, but it will always be in that plane and probably isn't too bad.

I think you will always find that sort of wear in these engines. It would be an ideal time to rebuild it, but it all comes down to economics.

For preservation, I would saturate the piston tops and cylinders with WD-40 and stuff rags in each bore, where the pistons are not at TDC. I reckon it's much better to store an engine like this, than fully assembled.

Hmm bugger.  No drama really, if it's going to be rebored so be it, it'll be seen too. Does make me wonder why it happened in the first place.  Why that cylinder and not the others.  There was a guy a few years back from Texas I think that had a black 6.9.  Forgot his name now but he had something similar which was welded then rebored.  Don't know which repair would be better, sleeve or weld but based on the other marks there a sleeve would be better me thinks.  Thanks once again for the contacts motec  ;)

TJ, if only that impeller was stainless steel.  I think it will be ok once cleaned up a bit.  There's plenty of meat on there but plenty of rusty bits to knock off too.

Actually, just looking at the pics, you should be able to get a reasonable idea of the condition of the pistons, by looking at the skirts underneath, when the pistons are at BDC.

The impeller is listed as a spare part in the EPC. I'm not sure about availability though. If it is the same as the square base pump, a used replacement could be sourced. I'm always impressed by the M-100 water pumps, in terms of engineering.

I think it will clean up.

Edit:

Here's a pic of the square based pump, from back in the day. My engine is ...12 1875. The pump must have been changed with the engine modifications, as it had the engravings that match the engine.

I have the early style water pump on eng #005522, they were used up till 005889.

As far as storing goes use thick engine oil or grease, WD-40 and the like run away.

How good is that!
Did I mention I'm in Griffith specifically and drink wine, my new best forum buddy  ;D ;D ;D 
 :D Kidding, but next time you're over if you've got time you'll have to PM me and come and kick tyres, experience the power of a d-jet 350 8)

Koan, I was thinking the same thing too.  I've got a bulk pack of CRC 5.56 and liberally sprayed a can and then some all through it and noticed the next day it seemed to be too dry.

TJ, thanks for the info and the pic.  I've got to go all thru those old threads.  It'll all start to make sense now that things are starting to look familiar.

Damn.... That's shyte dude.  I hadn't got to the point of analysing the block / heads / engine in general.. cause I hadn't yet picked it up when I found the other one.  :(  I'll ask Mark if he knew about it, my guess would be the answer will be "no". 

A decent engineering shop should be able to fix it fine though.  Let me know if you need me to tee anything up with anyone up here.


Thanks for the contacts too motec6.9.  Appreciate it.  Will scope the performance M100 cams for sure.  8)

Made me wonder if that was the reason for stripping it to begin with, but like I said, no biggie, it's going to get rebored and that'll be addressed at that time.
