Oil leaking from where drive-shaft attaches to diff (pinion?) in '91 sierra. Is the seal easy to replace for a semi-novice? How much should I expect to pay?


P.S. Only found http://webseven.org/outerlimits4x4/viewtopic.php?t=47191&highlight=oil+diff&sid=fd635f3c2266d979bcf11b7e06dd162f but did not ...

Have a look at http://users.mrbean.net.au/~rover/headlamps.htm

I found it very good info.

Just to clear it up in case someone is having a similar problem in the future and actualy does a search for posts on this topic:

The problem was that the Idle Air Control was stuck open. This probably happened in the time between when the motor left the old car til it was put into the new one ...

I agree. The gearbox in a zook is a super light weight if you compare it to something like a patrol. I'm only a little takka so I convinced a mate to climb under with me and it was out in about 55min (and I had no idea how to do it at the time).

I have given up on sorting out my idle probs and taken the sierra (G13bb) to a mechanic.

As I understand it, the 'throttle body' (not sure if that's the correct description being an efi motor) is not closing enough for the engine to idle at the correct revs. Apparently all of the electronics are ...

I have done an efi conversion (and used a lot of help from this forum). For the fuel pump, I removed the standard fuel filter, and put a second hand VN commodore external fuel pump and filter in the old filters place. At this stage I do not have a swirl pot, and havent needed one. If I ever burn the ...

Thanks for the ideas.

To clarify: when the engine is rev'd, it returns to an idling speed, but immediately speeds back up to what sounds like about 2500 rpm (very approximate as there is no tacho yet).

very very possible - I wasnt sure about a few things there. I'll look into it.

I've finally got around to finishing my G13bb engine conversion (into my '91 Sierra). It starts!

Now the problem is that the engine is reving too high at idle, as though the choke is always on. Anyone got any advise to offer? Is it possible that I'm missing a sensor (feed back loop)?

The loom has two positions where it goes into the firewall (one on the drivers side and one on the passengers side [ECM] ). Both sides have two large extra plugs - one blue and one white - which look identical. I think these, plugs on the ECM side, are for an Auto Transmission control module ...

I've have put a G13bb engine into a '91 sierra. I am up to wiring in the new loom and computer. I have managed to power up the old wiring loom (ie. I have lights, blinkers, etc) but have not yet sucessfully managed to fire up the starter motor, new wiring loom or computer. As far as I can tell all ...

I have the engine in, the only things left to do are the electrics and the fuel pump.

What are the minimum things to install in regard to the wiring?
Computer, injectors, lights, starter motor, altenator, oxygen sensors (airbox and exhaust)... anything else?

...I may be in over my head.

Any help ...

I have found a Jimny engine in good condition with low km (cannot be more accurate than that) with a wiring harness and ecu for $2500

is this a good price? I have read about people picking them up for as little as $1700, but this is the first one I've found at all!!!

I was told that it is about ...

That's the way, did you do a virtual lift or cut the back off while you had the grinder out.

LOL - No, I was doing it in the driveway at night under torch-light otherwise maybe I would have

How much rust did you find, when I took mine off the brackets had huge holes back the sills were hardly ...

...so it turns out I am much more impatient than I thought - I took to the spot welds with a grinder, pinch-bar and a pair of pliers, it all turned out suprisingly neat!

Thanks for the replys tho

I'm trying to remove the plastic sill protectors from benieth the doors of my '91 Sierra - How do I un-pick the spot-welds which hold the sil-protector 'bracket' to the body without damaging the body?

Cheers
-Ian-

I do have a small amount of lift (2").

I haven't checked anything yet, but I do intend to grease every nipple I find, except my own!

Hey guys,

Just noticing a bit of slack in the driveline when I back off and accelerate. I know that there is always going to be some slack, but how much? What is the most likely source? Is there a way of measuring this and comparing to standard?

Cheers

I was hoping for bible-quality info, and I'm very happy to get it.

Thanks to all those who posted. If I have any other querys I'll be sure to ask post them!

Cheers

(I have a self-diagnosed condition of excessive list making - sorry)

For a Jimny engine conversion to go into a 1991 Sierra I need:
G13bb Engine (from 1998-2000 Jimny)
Jimny wiring loom (& diagram)
Jimny ECM
Jimny radiator hoses
Jimny airbox + hoses?
Jimny headers
Jimny heater hoses
Jimny engine ...

das ist wünderbar

...I like it!

The car has 161,000km on the clock.

well I guess a new engine was always on the cards if the schmit really hit the fan...

I'll work on it for the time being - compression test is first on the cards

any other suggestions to look at and discount would be great.

Ok, long story short:

My '91 Sierra (just purchased) is chewing through a LOT of oil (we're talkin' >1.5L in 1000km!). It is not leaking anywhere. I have not seen any smoke, but was told that there were small puffs of blueish smoke under heavy acceleration. There is oil on the air-filter (but no ...

I posed the same question not so long ago, Sierra or Vitara?

I drove a couple of each, and decided to go with the Sierra - and haven't looked back I might add. There seemed to be a better selection of aftermarket products for the Sierra, and I just think they are cool!

I didn't care so much about ...

Just been looking at the Simex website, the figures quoted for the Centipede MT were OVERALL DIAMETER 775mm (30.5") and OVERALL WIDTH 279mm (10.98")!

Will that fit under a sierra with 2" spring lift? I'm looking at 30" MT's, but none of them are that wide! It also says that they need 8.5" rims ...

Hi,

I do about 50:50 onroad/offroad driving, and am what sort of new tyres to get, i.e. A/T's or M/T's. Offroad driving is usually in bush tracks, some rocky trails, and very rarely on the beach.

Another question: Is it better to get:
- cheap and nasty tyres cos they'll only get cut/chipped ...

ok,

So the mods planned so far are suspension, wheels, exhaust with extractors, and alarm/immobiliser... who the hell do you guys insure with?

the best I've got is GIO at $650ish, but that didnt include the exhaust or extractors.

Just wondering who are the best insurers to call?

I have a 1991 Sierra and am upgrading suspension and tyres.

Is it possible to run 30" tyres with only 2" OME spring lift with no rub in the guards or on the suspension? What offset will I need on the rims?

My goal is to have a Sierra with a lot of flex, but with a low centre of gravity.

Thanks ...

Hi,

I have bought a '91 Sierra for a bargain, but it needs a new clutch (which I knew before I bought it). How much should I expect to pay for it fitted? How much if I do it myself? Is it a very difficult job?

I have one quote of $600 - fitted, flywheel machined and oil top-up... is that ...
