Hi all!

Hope you are al doing fine.

My real main seal leaked so i pulled the engine. While the engine was out and the oil pan of i took the opportunity to look at my main bearings. They look fine accept for some initial break in marks because of Iron filings from al the new components (lifters, camshaft, rockers Etc. Etc.)

I ordered new bearings (sealed power from Rockauto). Now bear with me... These mains have 2 same size bearings for cap 2 and 4. For cap 3 there is a bearing with thrust plates. So that is the easy part. Now for cap 1 (front of engine). And cap 5 ( back of engine with the main seal). There is two options. One set of bearings has two oil grooves and the other set is wider than number 2 and 4.. Does anyone know which bearing goes on front and back?

I kind off remember reading somewhere that the grooved one goes on the back but now i'm not sure anymore. 

Thank you for the help.
