Trouble with oil high/low on Landcruiser

Lyn

Sounds normal to me! That what happened to a 60 and a 80 series I owned.

The only real problem I had with my 60 was keeping the crankshaft pulley on. (It came off twice)

The oil pressure should be lower when at idle then when accelerating, thats normal. But if its dropping back down again when at cruising speed, it could be any number of things.

Faulty gauge
Faulty sender
Oil pump on its way out
Oil too thick/contaminated

The pressure should remain the same if your revs remain the same.

Here is the page from the owners manual which shows the acceptable oil pressure range:

That's normal on the 60series. The oil pressure senders lose their calibration over time. Toyota got wise on other models and solved the problem by doing away with the gauge!

Its old an its an electrical guage.
Simple things first, clean all the earths in the engine bay, the neg terminal and the engine to chassis earth at both ends.
See how that goes.
If that doesnt work change the sender.

clean oil relief valve and replace spring and oil filter. spring is and releases under pressure

Hi Lyn
My old girl 92 T/D 80 1HD was rebuilt this time last year. We too had trouble with the oil gauge after a hard run in at easter. While cold it would go 1/4 then up the road it would register zilch. Tried 2 senders made sure the cables wernt squashed from the motor coming out. Even pulled the dash out to recalibrate something in there. Still no change. Since then its done about 25,000ks including the Cape. I keep en evil eye on the temp gauge and usually have to put a litre of oil in about 800ks. Strangely enough while towing the level on the dip stick stays at full. Been back to the same mechanic many times to double check everything. While hot the oil pressure is 75 which im told is normal. I have been meaning to put an extra gauge in but after 25000 ks if it was going to go bang it would have happened ages ago (touch wood actually make that a stump). I would be keen to see what other replies you get.

Hi Lyn,

We have a 84 60 series and the oil pressure sits on 1/4 when stationary and as we get going it rises. Sits on about 3/4 once u get going. has always done this so we are not too concerned.
