here's one i've never heard of but quite a few people seem to know or heard
about it,my son hs a 3.8, 92 cougar and has a very active noisy lifter,upon
oil change with a synthetic addative(car has quite a few miles on it)the
lifter did't quite down in the least,we will probally take valve cover off
and see whats the problem,, but he has gotten quite a few bits of advice
of adding trans oil to the motor oil and it will quite right down. does
anybody have any comments on this??? i havew heard a few tricks in my car
fixing days but never heard of this. bob
"pulp fiction"? Hardly... with old technology oils and old technology
engines, this was a fairly effective panacea - all depending on why the
lifter was noisy to begin with. ATF does do a pretty fair job at disolving
varnish and some other deposits (I still use it when faced with sticking
valves on the 7.3 diesel). I am unsure if this method will work with modern
oils and engines.... as far as trying it is concerned, it is inexpensive but
users should heed the caution that the ATF shouldn't be left in for more
than a few hundred miles...
Jim is correct, I've used type "F" to quiet lifter noise in a lot
of vehicles, the last was a friends Mazda Pick-up, '88 vintage,
good year for Mazda, if you ask me, but I ran the truck for
about an hour without a load, AKA, idled it, and the top end
noise went away...
I apologize for going against the crowd,
and posting what is being shown to be
how much tranny fluid are you guys having to use to quieten up the
What I normally do, I don't know about anyone else, is replace
the oil filter, and add one quart of type F, if I can find it, or
Mercon if I can't, and let it *IDLE* 'til the noise lessens, most of
the time, the noise will dissappear. Then change the oil as
you normally would, drive it for about a 1000 miles, then change
oil again. I did the Mazda 2 years ago, the noise has yet to return,
so I'd call it a successful repair...
My kid has a 97 Probe and after a couple years of "jiffy-type" oil changes,
some long overdue but with a famous brand Dino oil ... his adjustors made a
helluva racket, but after second consec Mobil 1 change, and about 10,000
miles, all of them are now quiet.
So once you get it/them quiet, WISE UP!
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
Is there a fix (other than replacement) for a lifter that leaks down
after the engine is turned off, causing it to tap for a few seconds on
the next cold start until it fills with oil again? Is this a problem
that really needs to be fixed? If so, is it all right to replace just
the leaky lifter without changing all the lifters and the camshaft too?
If you are pragmatic when things fail it shouldn't be a problem. If you are
like most of us in this group you are likely to get VERY mad when the next
lifter fails, let us know ahead of time so we can steer clear.
i started in a rebuild machineshop in 1970 and all the old guys there
used atf in their oil when they changed it. it keeps the inside clean..
also cleaned out a gummy lifter in a car that wasnt changed regularly. i
can remember an article in a rebuid magazine back then declareing
chicago cab co used it it their oil since auto transmission fluid
became available. they put 4 quarts oil and 1 quart atf and ran with
it.. so , it was and still is for many a common practice and wont hurt a
thing. if i hadnt grown up seeing it done by guys that rebuilt engines
for a living all their lives i wouldnt beleived it. lucas
Back in the carburetor days, just before we tore the engine down for
whatever reason. we used to mist a small amount of ATF down the air horn
with the engine running at a high idle. Created a LOT of smoke but took all
the carbon off the pistons and cylinder heads. The same can be done with a
small amount of water.
Oh those log cabin days were good.
