If it makes you feel any better, I did this over 25,000 miles ago to
boost very low oil pressure and haven't had any problems since.
Obviously a proper rebuild is the best solution, but I simply did not
have the money to do so and I have to figure that a half hearted
rebuild is better than no rebuild. Especially since it seems like bottom
end problems are usually the killer on 1500's, from the pistons and up,
these motors are close to indestructable. So I've decided to replace
the thrust washers and rod/main bearings every 50,000 miles or so
and see if I can make the rest of the engine last forever.
Best!
