 |
|
Just took a ride to do some testing on this solar power system and was wondering if these numbers looked right.
The oil pressure is 60 lbs cold and settles in at 20, as shown here, when warm. The oil temp is a proxy for the useless coolant gauge that barely gets out of the cold zone when this is where you see it. I make that about 230/240°. That's just intown driving, no real grades or high speed runs.
Both senders are mounted in the heat exchanger at the oil filter flange.
And yes, that is water vapor in the gauges which is very disappointing after I just replaced the heater core. I am not seeing any drips on the floor but now I wonder if it was the core or something else.

Paul, you say OP settles in at 20 but it's reading about 11psi in the photo. 11 psi at idle is fine for a wbx but you've got an ABA conversion so I'm guessing it's fine for your mitor as well.
If you're saying that it settles in st 20 psi say, at 2500 - 3000 rpm I'd want to learn more (I sold my wbx as a core when it was reading 24 psi at 3000 rpm; Bentley says a wbx should be about 28 psi at 180 degrees at 3000 rpm (don't quote me on those!)).
Dave's rule of thumb of 10 psi for every 1000 rpm is a good starting point.

Cold can be 60 or above but shoul rapidly lower.

I had internalized that 10lb/1K rule so I watch that. It is a little lower than 20 here. I did check the oil a couple of days ago and it was good.
The temp looks OK?

| I never measured oil temps with the ABA in my Bay -- and since I had an external oil cooler not the factory unit above the filter we'd be comparing apples to pineapples -- but your hot-idle oil pressure looks fine as long as it ramps right up when you open the throttle and accelerate. |

It does
pretty responsive. Never had an oil pressure gauge but I find it
informative.

You're good, then. Stop worrying and enjoy the drive.  |

Any idea why? I'm a bit disappointed after wrestling with that heater core job to find that I may not have fixed my problem. No visible leaks but why the fogging?

| Have you tried hitting the gauge with a blow dryer? |

Are there 12V blow dryers?
If dobryan has this issue and isn't stressed, I think I can calm down

My inline-4, albeit not an ABA and not in my van, runs at that temp. The oil pressure in mine at warm idle is double that though. That said, the low pressure warning in mine (at idle) doesn't go off until 0.3 bar (4.5 psi), so your pressure is fine if the ABA has roughly the same specs.

Good to know. The existing gauge and sender are still there and recent experience suggests they are in good working order
 I just did this to have some warning/trend to watch.

| Probably not but if you have an extension cord it would work. I have moisture build up in my Harley speedo once in a while. If I leave it in the sun or hit it with a low temp on my heat gun it goes away. |

No access to electricity out where I park, so not an option for now. Nor is the sun for a few months yet. As long as it's not due to a leak of any kind, I can live with it.
