Mainbearings ??

[BorJansson]

I found out that mainbearings in my engine are of different size.
Bearings 1 to 4 have .026 in case and .013 in cap and a 2 stamped in block at each bearing.
Bearing 5 have .013 in case and .0126 in cap and a 3 stamped in block.
Where can I find set of bearings with different sizes ?

If someone from Sweden or Finland read this - where do You buy GM spareparts ?

Try standard bearings and plastigauge for the clearance and see where you're at.

The .026 is in MM, which translates to .001"
The .013 is in MM, which translates to .0005" (half a thousandth)

You can buy .001" Oversize bearings from Mahle Clevite and mix them. You can mix a standard and a .001" together. no more than .001" though.
