Depends on how much it leaks. It can leak onto your clutch, giving your some
slip when first used in the morning, until the oil burns off. It can also
leave nasty stains in yours, and others' driveways. However, it's nothing
major and even if you fix it, it will return. I've had my rear main seal
repaired twice, only for it to leak again. This is very common to the inline
six.

The rear main seal is exactly what it sounds like: the rear seal of the
engine on the crank. It's costly to repair because of the 4WD system. They
have to drop your skidplate, disconnect both driveshafts, pull the
transmission + transfer case out of the engine, remove the clutch, drop the
oil pan (possibly unmount the engine from the mounts and jack it up for
clearance, and replace the seal and oil pan gasket and reverse the
procedure. The parts aren't much, but the labor involved is murder.

Easily fixed on your own if you're even slightly mechanically inclined. I'm
not sure if this is referring to the seal joining both halves of the
transfer case, or the seal around the yoke. Either way, it's not difficult
to replace.

Many mechanics recommend it. Basically, they hook up a bottle of some high
powered cleaner to your fuel rail, I believe, and clean out all the gunk in
there. They also clean out your throttlebody too. I've had my intake off to
repair the exhaust header, and there gets to be quite a bit of gunk in
there. I scraped it out and used carb cleaner to clean it all, including the
throttlebody, out before I put it all back together. I did noticed slighly
more power when I was done, but nothing to write home about since it has
147,000 miles on it.

You can buy some of that high powered fuel injection cleaner you put in your
tank from STP, Slick 50, etc. and get about half the cleaning that
professional job gives you. Those cans cost between $8 and $10.

Rear main seal is the one piece seal that closes the area between the
engines crankshaft and the engine block. If this is a 4.0 engine this is
a VERY common problem with them. Leakage there depends on how bad it
actually is. Put a piece of cardboard or paper under the rear of the
engine and see what shows up in 24 hours. IF you have a spot on the
cardboard the size of a dime or smaller don't worry about it for now. If
it is between a dime and a quarter then if you can spare the vehicle for
the time required and have the money get it repaired 400.00 is about
correct since it is a rather involved repair. Especially on a 4X4. If it
is over a 50 cent piece get it changed out ASAP since you are losing
quite a bit of oil.

About the same as a rear main seal BUT since the transfer case is
difficult to fill and check it would be a good idea to get it changed
out if it is leaking more than a drop or two per day. If it is just damp
around it don't worry about it.

150 would be a bit high for just an injector cleaning, BUT if they are
doing injector cleaning and top end cleaning then it isn't too bad.

Are you high? There's nothing in that $150 "induction flush" that cannot
be achieved with a $16 bottle of Chevron Techron or BG 44K.

Not as common as a leak at the back of the rocker cover *mimicking* a rear
main seal leak, as others have pointed out.

Um...not. There is no such a thing as them "doing a top end cleaning,
too". The stuff they hook up to the fuel rail is injector and top-end
cleaner. So is the stuff in the bottle labelled "TECHRON" or the can
labelled "BG 44K" that you buy for $16 and pour in the fuel tank.

Even if we assume that removal and thorough cleaning of the throttle body
and AIS were included, $150 is kinda rich.
