Early 968 rods.
Early rods vs late.
Did they change the rods?..... rod girdles?..... or both?
Can you tell about your car's rod components via vin or production dates?
Cheers,
Joel

Rods were changed. IIRR change was done in September 1993. This means around 1/3 or 1/4 of '94 MY engines used 1R rods. Factory document exists which lists engine numbers for first engines which used 2R rods.

It's already been posted by Tom Carson. Easy to find using "the Google."

For the 968, "as of October 1, 1993, engine #42R0958 - #42R50621"
Included are photos of the replacement conrod that is reinforced in the area of the conrod bolt surface...casting #944 103 111 2R (17.0mm thickness) vs. the original (and pathetic) casting #944 103 111 1R (10.0mm thickness).
Of course, they applied the usual weasel words “If during a repair, one or more rod nuts are loosened, all connecting rods should be replaced”…yada, yada.

so am i reading correctly from post # 5 that changing rod bearings on engines running the old rods (due to risk of fracturing the second time around on torquing), renders doing that impossible.
to change rod bearings on one of the older engines, the only solution would be running the new rods ?
bummer. glad i'm not running one of those engines. (i think). which brings us to the next question....

No, probably just that a tech cannot disturb the old rods without replacing them but could perhaps change an oil pickup tube or oil pan gasket. Policy I expect. You touch them, you change them.

Does anyone know of any early rods that have failed on a 968? From what I understand is that the 928 used the same rod. I have heard of a few 928's that failed but it does not seem to be real common. Does this sound right or am I completely wrong.
