Evening all,
Got a bit of a problem with the Patrol (yes hard to believe , I know)... 94Manual EFI with gas, When the beast has realy warmed up (takes around 40 minutes of driving ) we get a burnt oil type smell coming in...( realy putrid - like a diff oil or bearing grease heating up) have changed the oil in the back diff where I thought it was coming from but its still keeps coming back, have checked the wheel bearings for heat buildup and they seam fine. Any suggestions on where and what to
check and look for???
Any ideas will be most welcome at this stage.
Thanks, Boo

Does it have an airlocker?
if so are the solenoids inside the cabin?
If they are run a line from the vent port on the solenoid to the outside world.

Dont have airlockers,
It only started a couple of weeks ago on a trip to
Sydney. On that trip it took around 3 hours traveling before it was noticed. Since it only needs about 40 minutes before I can smell it.
Thanks.

you siad you checked wheel bearings was it the rear you checked or the front.
had a gq in a cpl of weeks ago with same symtoms.
pulled of the back wheels and slight oil leak on rear axle seal.
replaced seal and rear bearing problem gone.
wa only a slight leak but one hell of a smell when hot.
cheers

Checked all the bearings but not visualy, only checked them for overheating . Couldnt see any obvious oil leaks but in your words... "one hell of a smell". Smells virtualy gone as soon as you stop the sod, so its making it hard to pinpoint.

Will take a better look at the back bearings (just gotta work out how to get it all apart), I've done several other types of vehicles but never touched one of these and the Gregories is rather vague. Also, did you replace the bearing as
well as the seal and roughly how much should I expect the kit to cost. Last bit... is it somthing that is likely to completely fail assuming its only a small leak or can I put it off for a short while.
Thanks. Boo

Check the diff breathers also may help ??? not sure if this would create smell though..

Already checked the back diff breather wasnt blocked but dont think the smell is coming from there as its meant to breath and vent.
But thanks...

I have 94 Triton that out of the blue had that problem after a couple of hours on the freeway. Turned out it was gearbox oil from the breather on top of the gearbox. My last oil change I must have got a little too much oil in there. Funny thing was it took 20,000 km to happen. The mist of oil was going down and onto the exhaust. I rechecked the oil level and it was OK and hasnt done it since.

Thanks Petec,
Hopefully its behind the gear box (not positive yet). I havent touched the gear box yet but plan to give it and every thing else a good once over in about a month. Hoping to put any leaking seals etc off untill then.

Thats usually when you have some type of oil leak onto the exhaust..! It can be hard to see sometimes because the exhaust is burning all the oil.

Same type of car, same problem. Appeared after i changed gearbox oil.Overfilled and came up through breather which is just under where gearstick comes through to cabin. 5000 klms later has now gone.
