Replying to: salinity (Mar 29, 2009 10:28 am) --ALSO!! NEVER-NEVER run ANY of that 5wxx oil!! this stuff wasn't even used as break in oil back in the -70's..it's too thin!!.. -as a extremely poor person-forced to drive other's throw aways,and have bought more than one car,where despite what i thought was a decent test drive-when -80 degree weather hit-i'd start hearing a rod knocking..one car was so bad,and my need for a running car were so desprate,i ran straight sae 50 in it..it lasted me over two years!..not too bad for a 500.car.. --why the manufacturers recomend this thin-crappy oil is two fold..one is,a engine running thinner oil will get a ounce better gas mileage,raising their corprate fuel mileage..--second,running 5w20 oil ,the engine will only last about 100,00 miles-at best,and that's when they want you back in the showroom,so they can sell you a NEW one..making cars last doesn't do their bottom line any good,-it's called "planned obsolecense"..that's why fuel pumps-witch are a ROYAL pain to replace-only last about 80,000.. --if you want what you got to last,use the heavier oil,put in the zmax,don't put that cheap crappy gas in a old car(duuuuh!!)heavy synthetic-a10 or 15w40-50 in a jeep should keep it putting along for many good miles,-it won't help when you roll it down the hill sideways,but-ya can't have everything!!

My boyfriend and I are having a bit of an arguement that I would like someone to settle. I have a 1994 Jeep Cherokee with 237,000 miles on it. I have lovingly taken care of it for 10 years, but it is getting a little feeble. About 4 years ago I had to replace the entire cooling system (water pump, radiator, clutch fan, thermostat and housing and all the hose lines), I did it myself in the front yard, so I have an intimate knowledge of how it all works. Last summer I had some overheating issues and had to replace the clutch fan again and since everything has been fine. Fine, until my boyfriend drove it for several hours coming home from vacation (OBX to Maryland). We were loaded to the roof and had two large kayaks on the top, one of the largest loads the Jeep has ever had to haul. My boyfriend likes to drive as fast as possible, so I'd say between 80 and 85 MPH, he also made it down shift to pass other vehicles at this speed. Needless to say, it got too hot. He says there is something still wrong with it. Is there, or is he expecting too much from a 1994 Cherokee? I usually drive it at about 65 MPH and never have any problems. Not even in stop and go traffic where the engine is not getting |

Replying to: jeepgirl3 (May 26, 2009 6:26 am) --did it hurt it?,or is it still running-the way you normally drive it? -downshifting for power is better than "lugging" the engine..(from a old bus driver running the las vegas run many times)..saw many "city drivers" try todrive the desert grades in drive,while i had to downshift-and would burn up their motors!.. -downshifting isn't nesiserially bad,but watch the tackometer-and don't "redline"-especially an old,tired engine..you gotta be easy on old stuff-if you want it to last..it'd be like taking a old horse-loading it down,and expecting it to run the kentucky derby! i agree with you..take it easy on old gear-if you want it to last!!

| Hello...I am new to this group. I have a 2001 Jeep Cherokee 4.0 4X4. I just had the engine rebuilt by NAPA. The new engine is installed and connected. I started it up and it was idling rough. I noticed some vacuum leaks on the injectors so I replaced all of the O-Rings. That seemed to fix some of the problems. I checked the onboard computer and there are not error codes. The engine sounds great when you run in above 1000 RPM. It just when it idling is when it is rough. There are no air leaks. All of the sensors are connected. Before the engine died(before it was rebuilt) it ran and idles normally. Does anyone have an opinion? | |

Replying to: yeats66 (Jun 02, 2009 5:26 pm) Usually a rough idle will eventually be chased down to a vacuum line either partially connected, disconnected, or connected to the wrong place. |
