Alright, progress has been made.

TB/WP is back together. After I tension the belt and check camshaft timing, I will move on to pulling the oil pan.

Couple of thoughts while you are in there.

1. Oil pan stud kit.
2. GTS windage tray.
3. Deburr the cradle/crankcase return galleries down to the sump. If you decide to do this, clean up after with a can of varsol and a spray cleaner pneumatic gun. You'll spray varsol up into the bottom of the engine, with the engine correct side up so the varsol + scarf runs down on the ground. Messy.

If you know a machinist well, have him mic the journals and the bearings on the rods. Get your clearance numbers. If you've ever used plasti-gage that's another method to get a real reading of your bearing clearance. Follow label directions.

Thanks, docmirror!

1. Stud kit is onhand with the silicone gasket.
2. GTS windage tray, is that the same as the GTS oil pan baffle? If so, it is on order.
3. Will do on deburring. Thanks for the suggestion and guidance.

I have an excellent relationship with my machinist. However, he does not make house calls. I am familiar with Plastigage. I have picked up a package of green Plastigage and intend on checking the rod bearing clearance with it.

Learned today in my timing belt thread that I have had a 2mm preloaded flexplate pushing on the crankshaft in the Red Witch. See post #120:

http://rennlist.com/forums/928-forum...ming-belt.html


So...I might have found the source of the slight metallic sheen in the drained oil. If the preload has been pushing the crank against the thrust bearing for awhile, that could be where the particles are coming from.

I will inspect the thrust bearing as best as I can when I have the oil pan off.
I am still inspecting all sixteen rod bearing shells.
