After a tear down of my 2.0l engine I started the build up to the 2056 big bore upgrade. Having a Bridgeport I started with the (5) 3/8 oil galley plug on the block halves
Drilling a hole in the plugs and a slide hammer to remove the old plugs then started the installation of the new pugs I was able to order from Type 4 store.

Main bearing time:

ALWAYS measure your crank journals, case and thrust

I reviewed my previous owners receipts and build list and found the crank was installed with standard/.025 rod bearings no cuts to the case. So this is what i ordered. WRONG

1) The bearings I ordered were correct for the rods. I looked a set of shells on the old rods and confirmed the stampings on them at .25 and the rods fit perfect as seen owt the .0015 plastigage.
2) The mains had 2 problems:
a) The Silverline bearings I order were for the mains were wrong. Std, Std, Std. I needed .25, std, std and it ends up the mains were also cut to .25 mm
b) The box appeared to be unopened with a small cellophane tap in place keeping the box closed. I had an oil spill on my bench and the box soaked it up very well. soggy
Opening the box revealed the center bearing with multiple deep scratches in the babbit. Easily felt with finger nail and seen (see Photo)

This is the 3rd issue I had with the parts supplier for my 2.0l 914 and will not return or order from them any more...

The SOLUTION I now purchase all my parts from EMW (which I should have done in the first place). THEY ARE AWESOME! I have a set on .25 mains on the way from Jorge at EMW and will be here in a few days

While these may be useable (if they fit) But so were my originals and getting the crank polished deserves some good NEW bearings

IF anyone needs a set or part set of Standard main 2.0l baering please reach out to me. I can hook you up.
