The Brisbane 4wd show has been and gone for another year - Many thanks to Mark George, Allan Gray, and all the staff who helped make the show a success. One of the surprises you would have seen at our stand was the Australian-Made TOMCAR, a very capable offroad vehicle that can tackle any job thrown at it. We have one on display at the Brisbane branch if you didn't get a chance to see it at the show.
I was hoping you’d be able to give me some advice based on your experience. I’m 18 and just bought my first 4WD, a Mitsubishi Triton. I have a slight oil leak from the rocker cover gasket and I was wondering when an oil leak becomes a concern?
I’ve heard that unless you’re dripping oil on the driveway, it’s not leaking fast enough to warrant fixing. I’m probably losing around 100ml per 24hour time period. What do you think? Should I get it fixed ASAP or will it be ok for a little while?
My next question is more of a ‘how does it work?”. When my truck’s rolling backwards and I put it in 1st gear, it goes in smoothly. But when I’m rolling forwards and go to put it in reverse, it grinds. Why is this so?
Thanks for your time Allan, it’s much appreciated.
Matthew, fix the fool of a thing. It’s not a big job. You’ll have oil from one end of the motor to the other, up the back and everywhere else, you could end up having a fire, and why risk it? It’s got to be done anyway. Give the motor a good wash down, get a new rocker cover gasket, be careful fitting it and you won’t have to worry about oil on the driveway and you’ll keep your motor clean. You’ll be very pleased you did it.
As for your second question, your vehicle probably has synchro-mesh on first, which prevents it from grinding by allowing the gears to engage smoothly, but reverse doesn’t have synchro so it grates so avoid using it if you can. But that’s the reason, thanks mate.
Our boys had a great time at the Victorian LandCruiser Club's annual Cruiserkhana meet last weekend. They even took out a medal for their efforts in the balance comp!
Hi Allan, I drive a SWB Pajero which I love, but lately I’ve been having some problems when I engage 4WD. By process of elimination and the help of my mates we worked out that the passenger side CV shaft, thrust washer and wheel bearings were very much stuffed and the front driveshaft uni joints were shot as well.
After a few hundred dollars and a few hours on the tools I replaced all these parts and also installed brand new AVM hubs. However when I put it in 4WD I still get a large clunking noise. It sounds like the driveshaft but it’s too loud and inconsistent to be the driveshaft, especially after I’ve just replaced all the parts.
I pulled the cover off the front diff and inspected it to make sure I hadn’t stripped any teeth off my diff gears and they still seem to be in perfect order. So I’m stuck on what the noise is – any ideas?
Luke, not having the current mileage available it’ll be difficult to troubleshoot but I suspect a stretched transfer case beltage.
Hi Allan, I was on a trip through the outback recently, heading from Brisbane down the Oodnadatta and eventually ending up in Robe. It was a great holiday but I noticed something surprising about my snorkel that I was hoping you could shed some light on.
Driving in a convoy, there was a lot of dust being sucked into the airbox via the snorkel, even with leaving up to a kilometer gap between vehicles. After pulling my air filter at the end of the first day it was chock full of dust.
After blowing it out with the air gun I tried turning the snorkel head back to front. What a difference! There was next to no dust in the box and the filter remained clean for the rest of the trip. Do you know why this would have happened?
Well Bill, by reversing the snorkel head you will reduce the introduced airborne particles (by the time the dust has travelled past the air intake it’s too late for it to get back inside the engine to cause damage), you will miss out on any ram-charge affect (above 50km/h) but blocked air filters are not welcome around engines.
And it’s not that hard to turn the unit back around once you’re back on the hard stuff.
