I got most of the accessories off my 1.6TD that threw a rod....here's the pics of the carnage.

and a closeup of the internals at this point.

I think a rod endcap bolt failed (do not re-use these) but the final diagnosis will happen when I get the oil pan off, etc.

It that what they call "Positive Crankcase Ventilation"?

Sorry, that's a big bummer :cry:

Thanks for the reminder though, I'll be sure to use new bolts when I freshen up my TD.

Did the rod bearing spin/seize or did the rod just break?

Not exactly...I think I may find tonight when I go to pull the rest of the bottom end off!!!!

:evil: If the hole is the only damage to the block; why cant the casing be patched and welded? :shock:

Can you weld cast iron??

What about the water jacket?

Everything can be welded given the right bloke with the right torch :lol:
(Not me though I weld like I swim) :wink:

Does the water jacket reach down that far? :?:

Just checked...no waterjacket that far down...I will check with some of my friendly local skilled welders and see what they say about welding the block back together. I would do that if I could before I try to sell it (if I do sell it).

I know in the past people have looked at these incidents and after spewing up have just consigned the block to life as a boat anchor... Not me; something has to be truely trashed before I throw it out (and then it often takes the wife to bin it whilst I'm out) :roll:

:twisted: Why it occurs to me that it might be patchable; is because there's only sump pressure there and as far as stress goes it looks like its right in the middle of 'nowhere' :twisted:

:twisted: Maybe brazing is the way to go... :twisted:

Brazing doesn't work very well. I've got a one lung gas engine here that was "ventilated" in a similar fashion. Pieces were put back in and brazed. Stayed together, but leaks. You might try a good tig welder with silicon/bronze rod though. Don't have much faith in cast rod.

OOh, had a brainstorm. (watch out everyone)

A while back, there was a discussion about the maximum overbore of a 1.6 block - perhaps enough to fit 1.9 pistons. If this block cannot be repaired, perhaps it would be a good donor to test by means of cutting it in half... etc. or just by boring it as far as it will go to see just how far it can actually go.

Hey, that way if the block is trash, then we can at least use it for research. :twisted:

Just a thought.

What's the bore diameter on a 1.6? I think it's only a couple millimeters less than the 79.5mm bore on a 1.9 engine. The stroke was a bigger difference.

lord_verminaard · « **Reply #14 on:** April 01, 2005, 04:30:26 pm »

I think it's somewhere around 76.5 stock. The highest (factory) overbore size is 77.5. 3mm sounds like a lot to me, it would be interesting to see how thin it would get. (and if it could hold the pressure!)
