Oil Pressure

[al winter]

G'day, I have an 80 series Turbo l/cruiser (still with stickers which I'm going to remove tomorrow, had to buy a new hairdryer), but I'm after some more info:- My oil pressure gauge registers just on the first mark when normal road driving at about 80/90 K's. Now I thought this was low and was begining to think it meant a new oilpump or maybe new c/shaft bearings etc, but have been told by an independant mechanic and by the car yard I bought the car from that this is the normal pressure for these turbo powered motors.
I still feel a little anxious every time I glance at the gauge. Am I worrying over nothing or is there something wrong there. Any input will be appreciated.......Al

cant speak for the cruiser , but GQ,s sometimes sit on the lowest line on the gauge !!!!!
fit a mastergauge (fluid pressure gauge , not a electric signal type !!)
& see wat pressure it runs !!!!!

My 70 reads a similar reading.
I was worried too, so I took it to a Toyota. They did a pressure check using external guage & all was OK.
They suggested to me that my guage is old & could be replaced with a new one (which I thought will be quite expensive). I suggested that I replace with a VDO, which is on my shopping list.

Hi Moose & Baby Troupe, Thanks guys for the info, I will get a fluid/oil pressure gauge fitted and check out the results. I've only had the car since last November and I'm still finding little teething troubles My previous car was a 1985 HJ60 non-turbo diesel, which although it was slow I knew it would go around this sunburned land many times before it wavered a little. Last April it started a 15,524K journey from Perth to Port Lincoln and then on up thro' NT to Darwin, back into WA and down the coast back to Perth (well Mandurah), towing a 17ft poptop caravan, we were on the road for 184 days and apart from fuel it cost me $65 for a new regulator to be fitted in Coober Pedy and $100 for a oil/filter change and a grease up in Darwin. My only reason for trading it in for the 91,turbo 80 series was when we went on gravel tracks The Fuhrer didn't like the bumpy ride caused by having leaf springs all round. Its demise came about because I foolishly let her come on a fishing trip in my mates Patrol that had independant coil springing all round. That was in Port Lincoln and I never heard the last of it for the rest of the trip. ......Al

Never fear my good man , you have taken a step in the right direction.

I have a gxl turbo diesel 1991 80 series as well..
Arn't they just a wonderful truck to go cruising in. ! I'm with your mrs on that.
Anyways i've done the rock hopping and all sorts in my truck (not to the extent of some crazy folk in outer crew but none the less) LCMP and black duck and so on have all be crash takeled in my truck.

Don't p[anic about the oil pressure. Mines the same . It resides on the bottom third marker to one needle width under it !

If in doubt wack on a master gauge and check it. After that grab yaself a nice auto meter jobby and wack a bling bling cowl gauge on..all thats a damn site checper than a factory dash gauge, or you can get it recalibrated at an instruments shop. !

One work of advise, I found a web site called 80scool. post link in a second... Alot of the WORLD WIDE OWNERS all agreed on one thing..

GET THE SUMP OFF AND CHECK THE BIG END BEARINGS..REGARDLESS OF THE K'S ON THE CLOCK.

They all shagg out the big end bearings!!!!

I read up on this site and pondered the information and decided. Ok i'll do it. Well i thought it would be nothing to look at... BUT !!!!
Number three bigend brg... MY GOD !!!! rooted it was. i'll take a photo for you and put it up here...but #3 was the worst with 2 others showing signs for concern. My truck only have 300,000 on the clock and has has a reasonable service history....
after this i threw in some pennzoil 20-50 grade and it runs sweet and slightly better oil pressure for the sake of the brgs.

Do ya self the favor and check the brgs..
new brgs cost 36 bucks and all you need is some oil and a tube of chemical sealant to do the job if you have the tools !
27 ft lb and then crack it 90 degrees. And watch the rod edges..fuk...they are sharp ! I had claret everywhere.

Anyways ill get this info and post it up here for you...
Its cheaper to check the brgs. than to replace the crank, and a rod/s etc etc..

ok example of what the brgs do..



and here's the docco on the big end brgs...
enjoy and TAKE HEED !

after having a bit of a read..there has been more added to the file.
this caught my eye as it wasn't there the last time i checked but ..i have this sound as well...

Also, warning....amongst the 1HZ/1HD community we are finding increasing
reports of the motor generating a ticking type noise at 2200-2400rpm.
Basically this is an anomalise noise and while annoying, is not destructive.
However, a 1HD that has defective bearings may make this same noise (in this
case piston clipping the head) just prior to self destruction. Isn't life
fun?.

Thanks for the info Punchy, Yeh mines a GXL too and coming up to 250K on the clock, I shall look into the possibility of changing or at least checking the big end shells. My problem is I cant (thro' health reasons) go sliding around under the car so I guess its gonna have to be a service station job so I'll have to save the pennies and get it done, better than as you said having to replace the crank. But the change from the HJ60 to this one is just amazing, this is so comfortable to sit in and lovely to drive. It was a bit of a shock going back to a manual g/box after my last 6/7 cars being auto's but in my mind its worth it. My fuel consumption is better now, it takes 13litres to go 100 K's and thats just running around town, I've yet to try it on a long run, but this coming winter around early July we'll be hitching up the caravan and heading north to Shark Bay for a couple of months, and I'd like to compare the fuel consumptiom with the HJ60, that used to take 16/17 litres per 100K's towing depending on the road being uphill or downhill and of course the all important "right foot". I always kept between 70/80K's per hour when towing but on a few occasions would "clog on" a bit only to find the consumption would shoot up to around 19/20 litres per 100K's. I intend keeping to the 70/80/ with this car and hoping the caravan wont make too much difference. Cheers Al......

hmm sounds like you get great economics out of your beast..

i've got the two tanks as you will..and i'm lucky to get 750-850 + 10% variation from larger tyres out of my truck
so mine works out about 16-18 liters per hundred

I'm confident with after a fuel system rebuild and a repair to a leaking pump i should be able to get that down to 12 ish..
would be nice to get a 1000k's to the two tanks

good suggestions, i particularly like your suggestion to yourself!
