Please show me your tail

I have one of Spaceclam's brilliant dipsticks in my EV. I'd love to get one for the Grizz.

Whats so special about it?

Just get a dipstick OEM Stock for the Stelvio.  It's an o-ring sealed pull out jobbie for level checking.  If you need to fill, just remove the sleeve that holds onto the o-ringed dip sticker. They're not cheap though... About $50 from AF1 in Texas

I prefer it to the stock GRiSO dipstick and a certain someone here was nice enough to send me one from overseas just because I mentioned it!

Thanks again for that one!

It's actually readable!

It's a lovely CNC machined aluminum piece, with a cross-hatched band for the read area, and a nice meaty cap that you can actually get your fingers on when removing.

I'll post a pic when I get a chance.

I replaced my dipstick with an oil temperature gauge.  I was too lazy to do the complex Beetle oil cooler automatic bypass system, so I just use Beetle's earlier suggestion to block off the oil cooler with plastic strips made from an ice cream container (black of course).  I made two sizes, and keep an eye on the oil temperature, reducing the strip size when the temperatures go above 100°C.

My GRiSO doesn't loose any oil, but the temperature gauge doubles as a dipstick should I desire to check it.

Where did you get that from, Dave?

You mean Chocolate?

So is 100C the temperature to aim for or something a bit higher?
I think I read somewhere the oil is overcooled
I was wondering if I have enough air flow through my backing plate, if not I will drill the holes a bit larger.

Where is the optimal place to read the temperature, in the sump or somewhere on the block?

With your 1100 you don't need to worry about blocking off the cooler as they have a thermostat. It's only the 1200's that don't.

Any thoughts why the 1200 8Vs missed out, Pete?

My guess in this, as in all things Guzzi since the bean counters took over, is cost.

The weird thing is that the thermostat could easily of been kept in the lubrication circuit but it's the ungoverned cooling circuit that leads to the massive over cooling. I suppose they thought that since it was going to run so cool because of that there was no point in adding the expense of a thermostat that would in most circumstances be closed and putting one in the cooling circuit would of been more costly and harder to hide.

Thanks Pete, I will increase the hole size then, I don't think its getting over warm but we are not into summer yet.
Is there an optimum temperature for the oil in the sump?

Update: I doubled the cross sectional area of all the holes around the outside.

Over 90*C minimum. While water changes state at 100*C at sea level it will begin to sublime off a bit before that and because there is a constant throughput and expulsion of gas from the engine the vast majority of the moisture within the crankcase and it's contents will get expelled above that 90*c point.

How hot is too hot is governed by the ability of the oil to maintain its ability to do its jobs and modern synthetic oils can, and in the 8V more than the earlier engines, get very hot albeit momentarily in places like the galleries around the exhaust valves and the under piston sprays. Overall you don't want to see temperatures much above 135-140*C for any length of time but I've rarely seen temperatures that high even stuck in Canberra traffic on days when the mercury is hovering around 42*C! As soon as there is air flow through the cooler in those temperatures the oil temp will rapidly drop to 120*C or less which is fine with a decent synthetic.

Mind you, now I've got the Mana back on the road the number of times I'll bother riding the GRiSO in town in those temps will be measurable on the fingers of one foot! Mana is liquid cooled and has a very effective thermofan that keeps it sweet in even the hottest conditions!

BEHOLD!!
