Hi larry ;

it's been a rough time for many people , I'm glad you're taking good 
care of your liver....

I usually replace the main bearing shells when I do rear main seal 
jobs as they can be worn * just enough * to allow the crankshaft to 
sit a tiny bit low.......

 Good call on the magnetic drain plug , don't be askeert when some 
crud attaches to it , that's normal .

The road draft tube is _very_ important ! if you remove it , oil 
will burp out the open hole .

They do get all sludged up and the best & easiest way to clean 'em 
out is on the barbie ~ find an old Webber and get it nice and hot m 
throw on the Road Draft Tube and wait ~ once it gets really hot all 
the sludge inside it will begine to burn and it'll smoke like 
crazy , let it go until the smoking stops , be aware the smoke is 
terribly stinky , this is a weekend when no boss or SWMBO is around 
typ of job . 

DO NOT try to bead blast it ! you _CANNOT_ get all the beads and 
sludge back out of it and the beads will return to the crankcase and 
trn the oil into fine grinding paste that'll wipe out the bearings 
and journals... no foolin' .

Once it's all burned out , flush it clean , wire brush until shimy 
then re-paint with gloss black paint like it was when new , NOT 
matte finish like some think .

New correct ' Stove Bolt ' screws for attaching the oil pan are 
indeed available and best of all , they're Amnerican made ! .
