Anyone have a part number or can I just use grade 8 bolts? They are the side bolts that hold the bearing caps in place (not the top bolts but the ones that are on the outside of the block). A couple of them are stripped on the 5.3 I am rebuilding for my truck. I tried searching on Google but came up with nothing.

 

#12556127. They are sold individually. I would not use just a grade 8 as they have orange sealant applied to them to keep oil from leaking.

 

Thanks. I will have to run to the dealership and see about ordering some more.

 

X2, plus grade 8 bolts are only available in SAE thread, and the main bolts are metric thread.

 

Reuse them they only get Tourqed to 18ftlb....
