The continuing saga of the TR7 bearings from hell.  When we last saw our 
hero....

The crank won't be ground till Monday, and it's apparently a toss-up as to 
whether it will be done at .010 or .020.  I figure we're about 1/3rd through 
the project so far, and some random questions have come up I'd like to pose 
to y'all:

1.  I took the oil pump off today.  Like the crankshaft, it is also is 
scored/grooved -- in this case where the outer "star" gear rotates around the 
oil pump body -- leading me to further suspect that sometime in the past 
something disintegrated in the engine, spreading metal parts throughout the 
oil system.  Anyway, is this type of wear significant in terms of the oil 
pumps ability to pump oil?  I ask in ignorance since I really don't 
understand exactly how the two rotating gears are able to pump oil.  I'll 
also check the wear between the two "star" gears.

2.  I thought I would take the distributor out to clean it.  Since I already 
have the timing chain off and will have to make sure the crank, cam and 
distributor are all in the right position when I put the chain back on, can I 
take the distributor off without bothering to mark its location?

3.  I know what the clutch alignment tool is for when re-assembling the 
clutch, but Victoria British also sells a locating dowel.  What is that for?

4.  Moss, TRW and Victoria British don't carry the o-ring that goes between 
the pump and the pump cover. (they do carry the one between the pump and the 
block)  Any ideas of who else might have this part?

5.  I'm going to take a look at the transmission tomorrow, and I know the 
rear engine mount is totally soaked.  Any obvious gaskets/seals to replace 
while the transmission is out of the car?  How about putting in a new oil 
pump kit just for safety? 

6.  I'm also going to look at the steering which is really tight  -- always 
has been since I bought the car three months ago.  I know in my old VW that 
stiffness in the steering could be a sign of someone having tightened the 
adjustment bolt in the center too tight, sometimes to make a worn rack and 
pinion feel better.  So, what to look for in a TR7?

Am working to get some pictures up on the net.  In the meantime, as usual, 
thanks for all the advice and encouragement.

You know, if the engine blows up after we put it back together, how about 
turning the TR7 into an electric car?....
