Renoenvy08 Posted August 3, 2020 Share Posted August 3, 2020 I got my block back from the machine shop with new Pistons and rings, I dropped the crank in installed the rings, dropped the Pistons in, put the caps on. With everything loose it's hard to turn the crank. When I put 20 ft.lb. on the caps I can't turn it at all. Before I took the block to the shop I re ringed the original Pistons and turned the crank just fine the box for the Pistons says it's over .040 and that's what the shop did to the block. Any ideas?

Pete M Posted August 3, 2020 Share Posted August 3, 2020 is there assembly lube on everything? Link to comment Share on other sites More sharing options...
MJCARENA Posted August 3, 2020 Share Posted August 3, 2020 Take the caps off and use plasticguage to check your rod clearances. (Might of spelt it wrong.) Link to comment Share on other sites More sharing options...
jdog Posted August 4, 2020 Share Posted August 4, 2020 yep sounds like incorrect bearings, use plastigauge to check which bearings needed, you can buy it at the parts store Link to comment Share on other sites More sharing options...

JimB Posted August 5, 2020 Share Posted August 5, 2020 Are you sure the correct cap is on the correct connecting rod? Link to comment Share on other sites More sharing options...
75sv1 Posted August 5, 2020 Share Posted August 5, 2020 As above, lube, plastigage. You will need the .003, smallest. Also, did you have the piston on too? I'd do the crank and see if it turns. Also, I believe you should torque the center cap first then rotate outwards. Check the FMS. Then add the pistons and rods into the equation. I'd also swipe the bores with a light coat of oil. I clean the bores first with ATF. Link to comment Share on other sites More sharing options...
Renoenvy08 Posted August 16, 2020 Author Share Posted August 16, 2020 Just a quick update, got my new undersized bearings today (the only ones I could get). Ran the cap bolts to 80 ft. Lbs and the plastigauge says I'm within specs, so now I can actually start on my rebuild now Link to comment Share on other sites More sharing options...
