had the exact same thing on my block.when i sent it away for line honing it came back with spring washers on all caps.other engines i have disassembled have been missing the washers as described in previous question, and yes 2 bolts are not the same as the rest.i can only guess it was a change they made over the years???

all the early blocks to 58 had lock washers on the first 4 as john said none could use a washer on 5 or it wouldnt clear the seal holder.all later blocks had longer bolts and no washers.

HAVE dismantled and assembled many ys several 312s probably 20 292s over the years,all wher the same with regard to main bearing bolts,the rear cap had different bolts,thiner cap and no lockwashers. there was a report on this site to deepen the rear main threads and use a longer bolt to stop cracks to the block. i never did this update as the few 312s i did had no cracks and where basic stock engines

Check your CAN ISSUE under BPN 6345 and see what it says for up north.

That Parts Book lists 2 different Bolts, One requires Washers in 8 Positions and another which is Self-Locking not requiring Washers. Differet Lengths also. 2 7/8 requires Washers. 2 3/4 Self-Locking.

I think the rear cap bolts have no washers because washers would make the bolt heads too tall to clear the aluminium rear seal retainer.

Maybe the Bolts listed in Catalog are replacement Parts for the Ones originally using Washers which do not use the Washers. Ted will know when He reads this Post.

If you go to eBay and run ford 292 main bearing caps you will see the lock washers also 8 of the bolts have the same marking on the head but the bolts without the washers have a different head altogether. The guy says it’s a Dearborn block I do not know if it means anything.
