Exactly!

Re: sludge
 

OK.... I fully agree with you about maintaining the car properly, but I
have aquired a used 1999 2.0 Litre Hyundai Elantra.... lots of sludge,
so I added a quart of transmission fluid to the oil in the engine
crankcase and idled for 15 minutes and then drove about 5 miles down
the street and back and then immediately changed the oil and filter...
10/40 . Lots of crap came out and after 100 miles the oil looks nice
and clean but there is still sludge visible in the opening where you
add the oil..... should I leave it alone or get more aggressive with
???? The engine runs great with no apparent lifter problems, etc.
Advice please.

Personally, I think these engine flushes are gimmicks. I'd simply
maintain the car properly in the future and drive it. If it ain't
broke, don't fix it. The sludge itself isn't likely to cause any issue
at all unless it gets dislodged. I'd rather see it dissolved slowly
through regular oil changes than shocked loose and have a piece get
stuck in an oil passage.

It is kind of like asbestos. It isn't harmful if you leave it undisturbed.

Are you talking about sludge or varnish? It's more or less normal for
the insides of an engine to be discolored with brownish varnish and it's
nothing to worry about. Sludge is thick, black, goopy buildup. It's not
the same thing. I tend to agree with Matt, slugde is mainly a problem if
it's loose in your engine. Attempting to clean the engine (without
tearing it down and doing it manually) can cause more problems than it
solves. If the engine is running well, just maintain it an otherwise
leave it alone.

Re: sludge
 

I've done engine flushes on sludged engines and seen no appreciable
difference. It may wash some of the sludge out of the passages, but the
bulk of it remains in the engine. In my opinion, it's mostly a waste of
money.

Re: sludge
 

You might continually run about 1/2 quart of transmission fluid in the
engine. The detergents in the ATF will help dissolve the sludge. And 1/2
quart is a small enough amount that you're unlikely to get any engine
damage.

Hyundai actually at one time had a tsb that said something to the effect
of warming the engine to operating temp, draining the oil and installing
atf and replacing the filter, running for 20 minutes, and then draining
the atf and installing oil and replacing the filter. I cannot find it
online anymore, so I suspect they don't really want anyone doing this.
