It is what shops that don't first check the valve cover for leaking
will change rather than replacing the valve cover.

IF your valve cover has been replace by someone who knows how to tell
the difference between a genuine rear seal leak and a valve cover
leak, and you then would need to replace the rear seal, might as
well get this one done at the same time.

"Injection cleaner ? If it has never been done *and* you have
a preoblem indicating a possibly dirty injector, it could be
worth doing. Otherwise it is a really good profit center for
the shop.

Since Bush Gas, I haven't been able to run Texaco, Chevron, or Shell
regular in a 95 4.0 without mild ping. Recently the local Valero
station ran out of midgrade, and it seems that their regular will
actually run without ping.

In my old drag racing days we had to double the size of the jets to
run straight alcohol. So it stands to reason to effectively use an
alcohol blend like ARCO uses out here in Kalifornia, we would need to
use more product to compensate, or it would run like it was lean.

I can show records for multiple vehicles over the last 15 years or so
that show a consistent 10% drop in mileage for the 6 months or so we
are required to use the blended stuff here. That's a composite of
long highway miles and local puddle jumping. In the short term, the
same figures seem to hold true when I fill up with the blend in
Colorado to drive to Texas. I get a consistent 10% decrease no matter
which octane level I choose in my 88 4.0. Funy part is that going
south and east the prevailing winds are out of the NNW so I'm going
downhil with a tailwind on the way down while on the return I have a
headwind going uphill - and still get better mileage!

Corn likker is for drinking, not driving.
