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. |

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. -- DougW |

Re: good thing to clean out engine
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.

Re: good thing to clean out engine
Use a good detergent oil and an new oil filter, change the oil as soon
as the oil looks slightly dirty. If it is dirty in 100 miles, you know you have a sludge issue. If it is still clean at 1000 miles, the enngine has been taken care of. Takes longer but MUCH easier on an old engine than dumping in any kind of solvent or additive. abomb69 wrote: > 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. > > > |

If the engine has sludge, usually some is under the oil cap. The second place to check, and this will show the slightest amount of sludge buildup, is the CCV tube. I unhook it from the intake and see if I can blow through it into the valve cover. If it still blows clear, there is no sludge. If it is plugged, then some carb cleaner sprayed into the tube with a ream from a wire or air blow to clear it is in order. If this CCV tube plugs with sludge, then oil will start spitting into the air filter. At this point I would think on using a cleaner in the engine. I prefer to use a pint of ATF into the oil about 100 miles before a change. This seems to clean them out without being to harsh on them. Some folks actually remove the valve cover to make sure they get all the sludge out, but I wouldn't do this unless I couldn't keep that CCV tube clear and then I would want to pull the oil pan too.

Re: good thing to clean out engine
That line is extremely important. It sucks off the engine fumes and
condensation from cold starts. Without it the engine will fast fill with sludge and water and up and die very soon. You aren't talking using chemicals to clean sludge here, we are talking putty knife and pressure washer.... Our 88 has 315K on it and I keep that line working. My engine still only uses a liter of oil between changes...

I tried getting a piece of hose to connect it to the box, but every size I

That sounds like a personal question. *ducks and runs* The hose is a non-standard hard-line in the ZJ. You can either get one from the dealership or use a slightly larger rubber hose and a couple of band clamps. A little electrical tape or duct tape to build up the connector might be required. -- DougW |
