I need some help

[Mikey6981]

What is the life expectancy of a 4.0 out of a 93 ranger? I need to know for a lawsuit I'm filing.

 

[Original_Ranger84]

why are you filing a lawsuite? I would estimate about 200,000 miles average... well taken care of probably 250,000... neglected anywhere from 0 - 100,000 probably. If te engine had a defect... just whenever the defect decided to dump...

For one, why are you filing a lawsuit. Secondly, do you think "some guys on a forum said it'd last this long" would never hold up in court?

 

[Mikey6981]

Wal-mart F ed up my Ranger and they wont admit to there mistake. Thats what I get for being lazy. My attorney wanted me to find out an aprox. of how long they last. I figured who better to ask than people who own them.

They did an oil change and over filled it to the point that now I have oil leaking everywhere when it didnt when it went in. they are trying to say that because i changed to 20w50 oil thats what caused it. Then they tried to cover it up by draining some oil out.but when confronted they tried to tell me that 1/2 quart leaked out in less that 25 feet of clean white concrete with not a drop of new oil on it.

Most 4.0 OHVs can see 300K if you take care of them and don't abuse (and by abuse I mean: tow, speed, engine brake, load over 50% of capacity, rev over 3500 ever, let go longer than 3/3k w/o oil change, use something other than 5-30 or 10-30, etc).

I know for a fact that if you only change the oil once every 35,000 miles a 4.0 will just barely live to see 70k.

Ask me how I know that. Go ahead, ask.

how do you know that?

sorry....I just had to

How bad can that be though. Ive seen cars driven 2 days worth of driving with no ill effects after being overfilled.

If it's still pissing oil all over or bent a rod then, yeah, go after them and make them fix it.

If not, go get some new plugs, get the right amount of oil in it, start doing your own oil changes and forget about it.

Why are you running 20-50 anyway? Just curious.

35000 man? jesus christ, i thought i was doin bad at 1000 ovr

First shop I ever worked at a guy brings in his truck (4.0 SOHC Ranger) and trades it in b/c its about 5 years old and not running terribly.

We get it in the shop for the used car check and see the oil filter has some date about 2.5 years earlier written on it with a mileage of around 30 or 35k. The odometer had just a hair over 70 on it.

They guy who was working on it, who was also my mentor there ( I was still in school at the time) pulled a valve cover after getting a low reading on one cylinder on a relative compression test and finds the dump-bucket off its valve, laying there on the head. The cam had been pushing directly on the valve, already not giving it enough lift due to the missing thickness of the bucket, but also wearing both the cam lobe and the valve stem at a greatly accelerated pace.

We got a junk yard engine for it with about the same miles and there was no core, so we tore it apart for fun. Looked like that oil change 2.5 years prior had been about the only one.

Now for the good part....

The "new" engine came in with a cracked lower intake and you could see where water had gotten in and sat on top of the intake valve for cylinder 5 and rusted it up a bit. The parts guy who ordered it and my mentor, Ken, went back and forth for about a week over whether or not that cylinder would have any compression because of that. Craig said it wouldn't, Ken said it'd be fine.

Get the engine in and it won't fire up. No codes, no missing plugs, no obvious reasons for it. Turns over real nice, got spark, got fuel, just won't run. Do another relative compression test, all looks good, cylinder 5 (the one that was questioned) was a bit higher than the others, but since it only compares how much the crank sensor slows for a given cylinder to the others, that doesn't mean a whole lot.

Do a real compression test, cylinder 5 is the only one that comes back good.

35000 man? jesus christ, i thought i was doin bad at 1000 ovr

doing bad at 1000 RPM!?!? that's barely off idle! I'm saying don't go over 3500 RPM, not "don't over rev by 3500".

 

[Mikey6981]

the reason for the 20w50 I got a slight tick in the lifters and I was told by a ford tech that the heavier oil might help. and I normally do my own oil changes but I got lazy this time and i've learned my lesson.

Lol. Didn't think you would actually answer.
