#4 main bearing cap just slides into the block & actually you can hold the 2 sides of the cap & slightly twist it just a very small bit. The other 4 caps you have to lightly tap them into the block. Is this #4 cap OK?
Torque it and measure with a dial bore gauge. Then correct with staking each side of the register of the block and measuring over in over till you get it right.
It will feel smooth across the cap/block parting line when its right.
