Hello all,
I was just wondering what the estimated lifespan of a 4jg2 3.1
is. I have the opportunity to buy one with 80000 miles and was just wondering how much more life i could expect out of it. Obviously I would do regular maintenance and timing belts at their intervals.

Thanks everyone,

Harold

No idea on the 4jg2's, but I'd hazard a guess that it is just barely broke in at 80k. I would think 250k with good service would be possible.....

Check out <a href="www.clubisuzu.com" target="_blank">Clubisuzu.com</a>, they have a good forum with lots of 4jb1/4jg2 info. You'll have to convert 80k to km's though, thier in Australia <img src="/forums/images/graemlins/smile.gif" alt="" />

The only killer of these engines seems to be the EGR. It vents into the inlet manifold above #3 cylinder and this is the only one of the four to give any trouble.

I'd expect 3 times that mileage if it's been looked after.

hi, i was curious about the egr. i dont even know what one is, but when you say "taken care of", do you mean remove and block it off??? thanks

EGR= Exhaust gas re-circulation

Basically just vents some of the exhaust back into the engine to "re-burn" it to lower emissions. I remove it from all my vehicles that have it. Local emission laws may not allow that, but it can still be disabled. In my experience it works fine when new, but as stuff ages, it causes nothing but problems. Especially on a diesel with all the soot as opposed to gas engines. Gas or diesel, it will still get carbon build-up. One day it will stick, hopefully closed, but maybe open, and then you have an engine that will idle poorly if at all.

like breathing into a plastic bag

Like eating Sh*t is more like it.

AKA Just bypass the turbo. Brilliant!
