You do not want to spend part of your weekend doing this!
Look at all of this fun!
The red arrow shows the extra hole I drilled in this bearing. It didn't stop crankwalk, but, interestingly, the non-clutch side of this bearing half showed no wear. Hmmmmmm.
Here is the wear of the pulley side on the bearings. The block side is where I have the extra hole drilled. Notice how new looking this half still is.
Nothing stopped wear of the clutch side. Funny thing was, I checked bearing wear prior to going to Pocono Raceway, and wear was a minumal 0.003" of an inch, same as it was after the shootout. After Pocono Raceway, the wear increased to 0.008". Ouch! I had to see what happened, and this is the result. This still looks like some kind of block misalignment, or out of spec machining.
This is my new "Swiss Cheese" bearing. I reduced the size of the extra oiling holes I drilled, and placed them annually around the bearing. Notice, I placed two extra holes on each bearing half on the clutch side, and only one extra hole on the pulley side.
Since the oil is fed from a narrow groove around the center of the bearing, I had to grind small oil passages to the holes I drilled. Who knows if this will work, or make things worse? I hope I didn't ruin the integrity of the bearing.
I am carefully prying the crankshaft to the clutch side of the engine for end play measuring with a feeler gauge. Be careful when prying. The surface you are prying against is only aluminum, and also houses a crankshaft seal.
Here is a 0.005" feeler gauge, the 0.006" feeler gauge would not fit. Crankshaft end play is somewhere between those two measurements.
Good times!

Let's see what our AWD friends are doing.
Here is some of the fun our FWD brothers are having.
Just look at all of the fun I am having.
