86 Cherokee Pioneer knocking question-LONG
We've got an 86 Cherokee Pioneer that we bought in late 99.It has been basically "problem free" for us, we've put less than $500 into it--but, it has had problems with oil leaking/oil loss since shortly after we bought it.We have heard that this is a pretty common problem, especially in this year/model.
The people that we bought it from had the motor & tranny rebuilt, about 40,000 miles ago.Other than having to keep an eye on the oil, its been fine--up until 2 days ago.We live in upstate NY, about 12 miles from the PA. border--where cigarettes are much cheaper.So,my friend & I went on a cigarette run in the Jeep.We got there with no problems, made 2 stops, & headed back.
The route that we drive is mainly a 40 to 65MPH route, until we get off of the highway- about 1 mile from home, where you hit "Main St." (30 MPH/red lights) About 1 mile before we got off of the highway, the Jeep started to "feel funny", like it was running rough.I slowed down, checked the gages, & saw that the temp gage was a bit high.It wasn't showing any signs/smells of overheating, but there was a slight knocking noise.I got off the highway, & hit a red light.When the light turned green, it stalled, & died.The temp shot up almost all of the way, but still no signs of overheating--steam, smell, etc.I put the flashers on, put it into "N", & tried to keep my temper in check because we had several cars (with men in them) blowing their horns while they watched 2 100 lb. women push a Jeep out of their way.
Anyway, we managed to get it onto a side street, & I called my husband to break the news.He was in the shower when we called, so it took him about 45 minutes to get to us.He brought water, & oil, but the water level was fine, & the temp gage had gone down to normal.It needed oil, but it was far from "bone dry", so he put oil in it, & it started right up.The knocking continued, so we called our mechanic & dropped it off.He said that he tried to "get it to overheat" but it wouldn't.His verdict--"A rod is knocking, its terminal, drive it as little as possible, & put it in the paper for $500 or $600--a motor would cost you $1700 to $1800-- pulling it, sending something out, putting motor in.
My husband isn't the "mechanic type", & our mechanic has always been fair.But tonight, my friend's husband (the friend that was with me when it "died") asked if it was a "push rod" or a "rod bearing." We have no clue.He said that a push rod is fairly easy to repair, but a rod bearing is a pain.
If this is not a $1700 to $1800 repair, we might get it fixed--if it is, its obviously not worth it.Any info/input/advice would be greatly appreciated.
Thanks in advance!
