Outer Limits 4x4 Board

I have a 90 sierra softtop that is showing signs of being clapped out. Blow ing smoke after engine braking and the like. It still starts and runs smooth and I can still get her up to around 110 on the flat.

Generally when I go out driving I go out with the MJOC as the other car is a Jeep.

Last ...

I have searched and there are few different figures that come up for the normal pressure when a compression test is done. They vary from 140 -170.

I am getting the donk's compression (1.3L 1990 Sierra) checked out on Friday and would like to know what is considered good and bad compression. Any ...

I imported a BESTOP air freight from RRO in the US for around $400 including import duty (15%) and GST. It took about 2 weeks. There were a number of companys that would do it around that price.

How is the ride with the EFS suspension?

Mounted the UHF in the car and I found a good location for the aerial.

At the top of the windscreen are the rubber stops for when it is laid down. I fashioned a small bracket that is mounted using the existing screws from the driver side one of these. I bought the cheapest rubber whip aerial ...

Took it for a spin and couldn't get it to smoke (not that you can find seriously steep hills in the city)

I have also added Nulon Stop leak and and been offroad with no smoke.

The question is which fixed it???

It had looked like a terminal problem the other week and now I v.happy.

On the weekend I replaced the exhaust. I now have a 2" from the cat back with glass packed a sports muffler and resonators tucked up nice and high.

Headache now gone but I can hear all the other noises and even the radio!

Performance wise I was on the freeway yesterday with 2 people, a full ...

I have a snorkle.

Sounds like I should try and find extractors with a connection.

Does anybody know a brand that does have a warm duct connection?

You live and you learn

Thanx

I was reading on another site (Ausjeep) about resetting ECU/ECMs after modifying exhausts/air intakes etc, so that it takes into account the new changes. For the jeep they say disconnect the battery and turn the ignition to remove residual power/current. Reconnect and drive normally for 15mins to ...

The standard exhaust manifold has a recirculation line back to the airintake. Some extractors have a connection for it and some don't. I understand that is there to recirculate the warm exhaust air when it is cold to maintain a constant temp air flow to the engine.

Is the connection important ...

No extractors at this stage.

I have searched and there is a lot of info about 4-2-1, tri-Y, etc

The recommended exhaust size appears to be 2" and a V6 commodore cat is a cheap replacement for the sierra and a straight thru type muffler seems the go.

I have a 90 softtop sierra with a 2" hot dog on a standard exhaust (put ...

Last weekend was up at Toolangi and continuous blu smoke for about 30 sec after a long steep downhill. After that on the flat no smoke.

I had a look at the FSM and spoke to Suziworld. Both talk about the PCV valve.

Pulled it apart this arvo and the hoses and valve was totally blocked by oil ...

Where do you have the CB radios mounted in the car?

I have a soft top and was thinking the only available spot is on the plastic tray under the glovebox.

Are there any other locations?

The standard stereo is crap but it is all that I have and some music is better than none so I want to keep ...

The shocks to suit the OME springs are only $83 each.

I've got a 90 Sierra softtop. Where is the best spot to mount an aerial?

My understanding is get it up as high as possible. I'm looking at a windscreen mount (similar to a mobile phone).
Due to the edges of the bonnet rolling over the standard bonnet type mount doesn't work and I have no bull ...

Doesn't anybody have a comment??

Does anybody know if there are any major differences/drawbacks between the Airflow (~$270) and the Airtec (~$400) snorkels for a sierra. It seems like a big $$ difference for the same thing.

Changed all the oils I could. Boy were there some ugly old oils!!

Problems with rear diff and gearbox. Drain plugs are seized (well I can't get them out) so how do you change them??

I took it for a spin early this morning and on the flat I can get her up to around 120. I don't think that she would go much more unless the road was very long.

Put a hill or head wind in front of her and watch the speed dissappear.

Stock 1.3L

After using engine braking, if I give it a quick squirt on the accelerator. PUFF a big blue cloud.

During normal driving even with a good boot of the right foot it doesn't blow.

Has anybody had this issue?

It does use a little oil but excessive amounts

Is it worn valves ...

From the bfg web site min rim width for 215/75 is 5.5in. 235/75 require a 6"rim

About to get around to changing the oils and adding breathers and noticed that the drain and fillers have a square type fitting. Do you need a special tool to remove them or is there a simple tool like a 1/2" socket driver that you can use to remove them.

Does anybody know if the carburettor installed on an Australian delivered 1990 sierra 1.3L is the same as that used on the American delivered vehicles.

Quote from Rocky Road

This Suzuki factory part was released as a part of a Suzuki Technical Service Bulletin. And we quote, "...Samurais may exhibit a hesitation/flat spot, in any gear, when in acceleration from partial to open throttle." Basically, eliminates the flat spot in carbureted Samurais ...

The other week I was up at Gembrook and hit a big bump. Steering wheel was 90 degrees off centre. I looked out the window to see where the wheels were pointing. Straight ahead (drivers side any way). A little further up (say 5m) the steering had straightened up.

Was the steering off centre while ...
