You're not gonna believe this, but here it is anyway:

Thank You....
> What were your secrets?
Regular, sort of, PM...
every year (Christmas present to truck) anti-freeze change, spark plugs,
tranny/xfer/diff lube change.
A lot of the miles are open road / Turnpike / Interstate
> What brand of oil
Castrol 20W-50 in the engine
Valvoline or Castrol 85-140 in tranny/xfer/diffs
> What frequency of changes
For the first 15 or so years, every 10K miles + filter
Past few years, swap about a gollon at 5K, complete+filter at 10K
Past year, full change +filter at 5K
> Valve adjustments
once, at about 300K, didn't need much...
> Significant repairs
ummm, Factory clutch & pressure plate died at 301K miles;
pressure plate 'spring fingers' wore off....
Knuckle bearings, wheel bearings....
Oh, I'm still on factory calipers, rotors & drums !
( drum cylinders have replacment pistons/seals)
rear drive line U-Joints a few months ago
Tie-rod ends a few years ago....
I'm not sure if any of the above is 'significant'....
In the plans (budget) H55, then I have the excuse to rebuild x-fer,
front output bearing is very noisey, drips lube - no pubbles, just slime...
The blow-back does serve, however, as underbody rust proofing
> Carb rebuilds
Factory card, cleaned & 'rebuilt' once, about 3 months ago,
new secondaries diaphragm...
> Also curious to know how may intake/exhaust manifold
sets you have been through. They all seem to be bad by 200K or so.
My intake does have the notorius 'crack'; as long as gasket 'tween it
and ex mani is OK, crack is 'harmless'
Ready for this ?
Factory Intake & Ex manifold. Replaced gasket (double gasketed) about a year ago
Factory tranny & xfer too. Factory dizzy, but new advancer diaphragm 'thingy'
(expensive danged thingy ! )
However, I'm on my 3rd radiator, 5th or 6th alternator, 2nd P/S pump
Swapped the 3.7 diffs for 4.11's (both have ARB air lockers), lift via springs (MAF Safari) 35x12.50 (BFG ATs of course)...misc other doo-dads....
And od have rusticles here & there....a constant game of rust and mouse...
