The temp on my 93 Hilux got very high for about 10-15mins (close to the red, but not into the red) on Saturday coming up a long hill in 35 deg temp. Have since taken off the fly-gauze on the bullbar designed to stop grass-seeds etc clogging the radiator as I suspect this was the problem since it had a brand new radiator just 6mths ago which seems to be operating fine....BTW I was not driving it, if I had been I'd have stopped and pulled the gauze off straight away....and it was being driven harder than I drive it! It had been up this hill before in about 27 deg temps with no rise in temperature, but 35 was a different matter.
Anyway, when it got home, I noticed a fair bit of oil dripping off the bash plate, and on the front suspension components. I degreased it all the next day, took off the gauze, and took it for a 50km spin down the highway at 100kmh. Temp was normal the whole way (just below half-way), but a few drips of new oil appeared on the bash-plate after parking it for a bit. It seems to be coming from around where the fan belt wheel on the front of the engine is situated. Not ****** out, just weeping a few drops.
I'm guessing the oil got too hot and thin and a seal or gasket somewhere has leaked.
Any idea what it might be, and what it is likely to cost to fix?
Was thinking about selling this old girl and upgrading, but after seeing how it put a 2017 BT50 to shame on rocky river exits on Saturday, I'm a bit keen to keep it going. It's been a great old rig, I'm a bit attached to it, rough as it is.
