Engine machine shop destroyed my block

Post by John@RED » Mon May 07, 2018 8:03 am

A wonderful engine machine shop just made the bores 0.00008 to 0.00015 bigger than what I asked:
what can I do now to save the block, except sleeving it, beside asking them for damages?
:evil:

Change the temperature of your shop and remeasure.

Obviously that was sarcasm but it reminds me of a block that I checked for a Ford dealer once. Newer truck was getting a new replacement block 351W for some reason. The mechanic thought the pistons from the old block felt loose in the bores. They sent it over with the spec sheet from Ford still attached. The spec on the bores was 4.0000" (-0.0000" + .0040"). It was 4.0040" right on the nose. I know I've fretted over a few tenths too big but then I remember that Ford block.

Please describe the measuring process used to determine 80-150 millionths.

x2 with head guy!
If that veriation bothers you , then don't even want to know how the Bore size can change from side to side and top to bottom just from normal differences in coolant temps seem within a running motor!

Your rabid over nothing!!!

John I get the feeling you may have your decimal point in the wrong place I suggest remeasuring the cylinder and verify you're measurements and re-post if necessary

Decimal point in the wrong place has to be what makes this make sense.

lol.. right. Surprised no one else even assumed those nearly immeasurable numbers could be off right away in this thread. Would guess it's more likely .0008 to .0015. And if that's closer to reality?.. then hardly what most would call "ruined".

I'd do 3 things there and then just run it.

1st. Ask for a partial refund since it never hurts to ask. Be politely firm but seem highly agreeable and could also bait them a little by saying something like.. "was planning on bringing XXX parts in to have more work done in the near future but now have concerns about them not standing behind their workmanship". That puts them in a situation where they think they can reabsorb some losses related to this partially refunded job towards future invoiced work.

2nd. Gap the rings to fit those specific bore diameters. IIRC, and I may not, every .001" of bore increase results in around .003 larger ring end gap. If you need to order new +.005" "gap to fit" rings then I would first try to swap them out at place of purchase, or if non-returnable?.. ask the machine shop to pay for them due to the larger overbore.. or just order you a set from their distributor and swap yours out.

3rd. Once the issue has been remedied to the acceptable outcome.. run like hell away from that shop cause being .0015" out on an overbore/hone job is downright horrible quality control regardless of how it happened.
