good thing to clean out engine
 

Anyone know of a good chemical to clean out and engine when you change the
oil?? besides just new oil....I have a 93 cherokee with 225k on it and
wanted to maybe get rid of some sludge build up inside.

What makes you think there is sludge inside? If there has been any kind of
responsible maintenance, there probably isn't. If there is and you try to
flush it with chemicals, you are going to loosen all that crud and get it
into your oil pump, clog your filter, make the bypass open, and then it goes
straight to your bearings. If you're serious about cleaning out the inside
of the engine, then you have to remove the oil pan and the valve cover to do
it right.

Back in 1976 I had a Plymouth Valiant that would only take three quarts on
an oil change. I guess you all know the reason. Things have gotten a
little better in the lubrication business since then.

Sea Foam from NAPA.

Just follow the directions.

About once every two years I do the SeaFoam, then use a
dealership $17 oil change coupon. Drive another week
on that, then drain and refill with synthetic.

Add a little ATF (1/2 quart) and let it idle for 10 or so minutes. Don't rev
the motor during this time. You can also buy 'motor flush' at any auto parts
store. Both work well, but don't take the motor above idle while it's got
the cleaning solution inside, you will ruin the bearings on an old motor.
