156k+, HG done by PO, used to beat on her (when i was payn $2.25/gal)now she's babied and soon to be swapped. she's leakn all over, but i no gripes with the 3.0 other than lack of umph and less-than-spectacular fuel economy.

 

I got a 3.0, just went over 204,000, and it still runs great. I love my 3.0. I'd rather have a 3.4, but for a 88 4runner, its the biggest, fastest engine they made for the 1st generation, and thats the kind of truck i wanted, its just preference, the 22re's are the most reliable but then again so are all toyota engines I just have an upgrade on the 22re. either way they will almost definetely carry you over 300,000 if you maintain it properly.

 

its not like I would excpect a chevy to get me this far, and i beat the crap outa my runner.

 

i have a 1990 second gen 4runner manufactured in November of 89'.

It has just passed 247,000 miles on it, the only problem is the fuel pulsation dampener screw fell out and caused a fire. Melted the whole passenger side of the wiring harness, among other stuff.




But what really says something, is even after that, 247,000miles, it still has original head gaskets, runs good!

 

ouch!! sorry man....bet if you replace all the burnt stuff, she'll fire up and go....thats why I love toyota!!

 

No that happened the day i got it. Its been fixed for about 9months now! Still runs good.


Good trucks, except for replacing parts one after the other. But that is to be expected on an 18 year old truck!

 

almost had that happen to me, i caught it before it completly fell apart.

 

somebody tell me how to start a thread

 

where exactly is this screw... im thinkin maybe i should check mine out...lol...i have enough problems already!!lol

 

dude...go to the home tab..then forum tools..then start a thread... or read the faq...that usually helps!!

 

Its on the passenger side of the fuel rail. You have to remove the plenum, its a PITA. But anyways, we ended up putting locktight on it and putting it back in.

 

back there!

 

ahh...ok...just had that apart couple weeks ago, and is gonna have to come apart again soon...Ill make sure to locktite it!!

 

There is a little plastic cap on the end, take that off and just make sure the screw is still in there tight. I don't think there is a need to take it out and bother with it, if its fine.

 

it is a PITA, but if you label everything while you are taking it apart, you will be fine. the new one i got from toyota had the screw in it. it just keeps the diaphram centered in the damper. the one i saw at schucks didn't have the screw but the threads were all crappy, so i just go the toyota.

 

hmmm...i'll make sure to look at it next time im in there....thanks for the info!!

 

Exactly, anytime i have to take the plenum off, i use tape, label everything and take pictures. Makes it a bunch easier.

 

ha...you dont need to label anything unless the plenum needs to come off...you can just loosen the plenum, and anything else holding it stay and flop it over... lean it on the quarter panel... really not that bad...1st time took 5 hrs(to get to knock sensor and put back together)...next time i bet ill be there and done in 2

 

i thought about that, i just didn't want to lay the plenum on all of that wiring and stuff, plus i just liked having it out the way so i wouldn't have to work around it. mine fuel damper was so tight i had to have my dad hold the fuel rail with a crescent wrench while i loosened it with a combination wrench.

 

The 3.0 may be one of the worst Toyota engines...

But what is that saying? It's still more reliable and will give you longer service life than its competitors.
