grease/doorhandle/motor flush..long...

[WAUFX at aol.com]

Ok listers!

I am planning on lubing and greaing various parts of my dear 4kq's soon, and 
need to know the proper/best lubes and greases for the following 
locations..also..where do you guys get your stuff? I was unable to find 
"Lubro-Moly Hi-Tack" spray anywhere and resorted to using lithium spray 
grease and brake caliper grease on my doorhandles...what have y'all used on 
these locations? What works for you? Techniques are also greatly appreciated.

doorhandles?
sunroof tracks?
cleaning and lubing window switches?
my car shifts hard...I would like to try lubing the ball joint that the stick 
attaches to before I delve further into bushing and other stuff within the 
mechanism...there appears to be a white paste-like substance there 
now...what's the deal with this?

also...is there a preventative maintenance to do to prevent the odometer from 
failing? Maybe a spray lube with teflon squirted somewhere? Where and how, if 
this is possible/advisable?

Now onto the doorhandle problem..after wrestling with my new used driver's 
door handle (many thanks to Chris Semple!) and the pins to connect/disconnect 
it and changing the lock tumbler...I put the damn thing back together and it 
works wonderfully...except now the door no longer locks! *&%#%^%&!! It will 
lock from the inside and power locks are fully functional. However, turning 
the key in the lock cylinder from the outside does nothing either way the key 
is turned! The key turns but no locking action whatsoever. Help, where did I 
go wrong? And what is the solution?

And finally...

Motor Flushing. Yes? No?

I went to the parts store and found some GUNK Motor Flush in a round silver 
can. However, the parts d00d said that he flushed his 79 Ford Fiesta with it 
and ruined his "moter". Heh. So what should I do? Car is an 86 4kq with about 
250K on it (broken odo of course) with tappy, loud lifters and too many oil 
leaks, one from the oil pump gasket and another from where the transmission 
meets the engine (I think). And another from somewhere else...<sigh> I am 
scared of either a) destroying my engine (this engine is the peppier one of 
my 2 4kq's) or b) causing many more leaks or significantly worsening the 
leaks I do have...advice?

Any help is _greatly_ appreciated.
