Noisy Lifters in Ford 4.0 L Ranger
Lorne Bakanec
I own a 1991 Ford Ranger 4x4 with a 4.0L V6 engine with automatic
transmission. The truck has 100,000 miles. Recently I've noticed a
tapping sound on the right side of the engine. I think it maybe a
lifter problem but am not sure. It does quieten down once the motor
has warmed up (10 min). If it is the lifters I was wondering how hard
a task it is to repair and how long I can go before having the repairs
done.

Oil, Rislone, or Wynn's Friction Proofing and see if it goes away. It
would be much much easier than the repair. Assuming you use this and
the lifters shut up you might not need a repair. I have had engines run
with seized lifters. The neighbor of a freind bought a mid 50's Chevy
new during the 50s and found it was missing an entire piston and it ran
(had no power though). Try some Marvel or something and see if it
clears up.

Marval Mystery Oil is really not the best choice. It will dilute
the engine oil and can cause increased ring and bearing wear. Naturally
it would be ok to use MMO as a flush right before an oil change, but
then you can make (or buy) a much more powerful flushing agent yourself.
Anyone who would like the recipe for such a flush can E-mail me.
The best choices for long-term additives are either Rislone,
Stewart-Warner CD-2 oil detergent, or GM's Engine Oil supplement. I
prefer the latter two myself.

I concur. GM's EOS seems to work.

stop your lifters from tapping. I use it to flush the engine, or a tiny
bit at the oil change, and it keeps the engine clean. Actually it IS
the best choice because nothing works quite as well on lifters. Next in
line I put Wynn's Friction Proofing engine Tuneup, it is about the
second most effective. I used Rislone, and while it isnt as good, it
can be left in. I have put high concentrations of Marvel in lawnmowers
during the summer, and I have yet to have any wear problems. That is 16
years and counting on my Snapper which gets heavy use.

Thanks for all tips. I have tried the Wynn's product because it was
available. It has helped a lot, but I still have one or two lifters
that actually seem to knock louder. It maybe just because all the
other lifters are now quieter!! Another thing I noticed is that these
"still noisy" lifters will get quiet then loud then quiet then loud
over a period of time (typically a minute). After the truck warms up
(approx 10 min) the noises go away. My question is should I add
another can of this "cleaner" or is something else required.

One of 2 possibilities.
1. The lifters are mechanically shot. Cure: replace them.
2. They are sticking due to the sludge and varnish petroleum oil makes.
No way to know which without taking it apart or trying Amsoil engine flush.
Dump a can of Amsoil Engine Flush in with a new oil filter, leaving the old
oil in. Idle it for 20 to 30 minutes. Dump the oil and replace with cheap
petroleum oil with a new filter. If the noise stops, and you have no other
motor problems, switch to Amsoil Synthetic oil, which cant make the sludge
and varnish that sticks up lifters.
If the noise doesn't stop, trade the truck, or put up eith the noise and
reduced performance, or replace the lifters.
Over the last 21 years of using and selling Amsoil I've had results ranging
from lifter noise stopped, to the same noise to louder by flushing. I'd say
about 3/4 of the time it's just sticky lifters and the problem is solved.
You can find Amsoil Engine Flush at my web site:
Zap me an e-mail if you have more questions.

much cheaper than Amsoil, and works probably as good or better!

When another poster asked about *his* problem, he wisely said
Spamsoil dealers need not apply. Looks like that was a smart idea and
Lorne should have done the same. Live and learn, as they say.

Well, it depends on which Wynn's product your referring to. If
it was the Friction-Proofing goop that someone else recommended it's not
surprising it didn't work well. Not only does that stuff have very
little in the way of detergents or cleaning solvents, but it can
actually make lifter problems worse. Hence I would never recommend the
use of oil thickeners such as Wynn's or STP for sticky lifters.
Try changing your oil again (to get the Wynn's out) and put in a
15w-40 universal or diesel grade oil. Leave it one quart low and then
add two cans of either CD-2 oil detergent or GM's Engine Oil Supplement.
Both of these products are readily available and perform about the same,
though last I knew the EOS cost about twice as much. See if there's been
any improvement after 1000 mi then change the oil+ filter again.
If the above doesn't work, let me know and I'll tell you how to
mix up a simple quick-flush which is alot more powerful than any canned
or bottled product you can buy.

the first thing i would do is to install a manual oil gage then start
the truck cold. record the oil pressure reading and keep track of it .
if the oil pressure is low the lifters will rattle. if the pressure is
on the the low side you may wont to change the oil pump or adjust the
pressure up a little to compensate for wear and age. if the oil pressure
is good then check for rocker arm wear/adjustment. badly worn rocker
arms or worn push rods will also cause your problem. if you decide to
run a nother can of that chemical to clean out the lifters be sure you
change oil and filter also. might also change oil brands or weight also.
