WK2 Failed Diesel engine

[Treebreakerbob]

I am thinking of doing 10-40 in mine (MY13) as just recently the oil light in the morning first start is illuminating and staying on for a second or so. Don’t really recall if that was normal as it was always the throttle body light would cycle through. I mean if the oil drains from the filter body as they say it does, then I understand the slight delay in oil pressure, again pretty stupid design unless you want failures. The other more serious thoughts are main or big end wear. What ever happened to oil pressure gauges that connected with plastic tube and had the capillary tube inside, no electronics except the internal light for night driving

True, though I did have one blow in my G60 patrol as I was lugging up a huge hill near Tabletop NSW, it went that fast the gauge jammed and in seconds siezure....................truck toed me to top of hill, so I pulled off the line, fitted a plug and rolled down the other side in gear to turn everything then flicked the key near the bottom, it all fired up and we rattled away to Stanthorpe where it spent a few weeks getting a rebuild......... had a big van on the back, those old engines were of sterner stuff than now though must have been in 1981.

My previous WK2 would do that...I mentioned it on here a while back. Often at first start up the low oil pressure light would glow for 2 or 3 seconds and I could here the usual engine noise that initial low oil pressure causes ...like tappet noise.

It never changed right up until I drowned it...it was doing that for maybe 15,000 kms before it's demise at 195,000kms...which definitely was not caused by low oil pressure, more like water pressure in intake!

Whether it was bearing wear causing it to take extra time to get oil pressure up, or whether it was in fact the oil draining back out of the filter therefore having to pump the filter full again to pressurise I don't know.
At the time though, I put it down to the oil filter slowly draining overnight...

The one I have now doesn't do that...maybe the "non return" valve in the housing does weaken over time?

You lot have got me jumpy now .................. ripping thru the hills near Crows Nest and I hear this damn tapping/knock sound, bluddy near did myself but until I could find a lay by the grey cells ticked over, not engine said little voice in head, wasn't 100% sure though, so pulled up did walk around the whole rig, ah, ha, ratchet strap end for Kayak had come loose and was flapping on roof rack, think I will take hearing aids out for rest of trip....................

...just don't activate your SRT gauges while hurtling down the road drover, the oil pressure reading being algorithm based definitely isn't accurate. On a couple of occasions while driving I have activated the oil pressure gauge to find it reading zero!

After the initial cold feeling washed away I realised if the oil pressure actually was zero, there would have been lights and buzzers going off so I would have definitely known about it...lol

Have had that happen, seems like a boot up problem in the app is the problem and being in kpa all I know is the numbers move in time with the right foot so Im happy, not changing my read outs though ...
