[FIXED] High oil pressure

Same issue here: I tried some quick missions and instant action with cold start, both in the trainer and the P51, and when engine starts the oil pressure needle goes to max value in the scale and remains there whatever the oil temp.

Is this high oil pressure bug why I cannot now fly constantly at 46 inches and 2700 rpm without the engine seizing?

I think no, did not recognize any trouble with engine caused by hight oil pressure (but who knows). No trouble with constant power engine setting with auto coolants setting.

It is probably only indication bug, no functional.

can you attempt to hold down the oil dilute switch for 5 mins in flight and report your findings?

for 46inHg/2700rpm at low alt./aprox.500kph ... nothing

map setting was "default" instead of temperature, i set it at 15°C

engine parameters were without any change

Please hold off on the "me too" and off topic posts in the bug report section, guys.

There is some good news though, the problem is fixed in the closed beta version so hopefully it won't be too long until it gets rolled out into release.

I was going nuts not being able to start in multiplayer, but always first time in Single.

Thanks for the explanation for this problem, and I hope its fixed soon.

Is there a work around ??????

No.

But you can dilute the hell out of the oil system, this helps.

The flight manual states that dilution could be necessary on ambient temperatures below 40F and "Once the engine warms up, the gasoline in the oil is quickly evaporated". Well, I didn't note any difference in the time to evaporate the dilution regardless of temperature, it took about 10 minutes whether the engine was completely cold or near operational temperature. See below.

I noted that when starting with an ambient temp of 68F that with about the lowest idle RPM (throttle pulled all the way back) of about 600 oil pressure is still around 150lb. So I waited in idle for the oil temp to increase and presser to drop in to normal operating parameters of about 80lbs. I waited about 30 minutes(!!) and oil temp only went up to about 55-60 with pressure only dropping to about 125lbs.

I restarted same mission and this time right after startup I diluted the oil until pressure dropped to about 100-110lbs; I had to hold dilute for about 15-20 seconds until I could see no further change in pressure. Then I accelerated the game by hitting <Cntl><z> about 12 times and waited while observing oil temp and pressure.

After about 10 game-time minutes pressure started to raise again with oil temp at 60F, so I diluted again for about 15 sec and pressure went down to 80lbs (green).

I waited again and observed temp and pressure. It seems at idle RPM's temp only goes up about 1° per minute linearly. I think (my anecdotal experience from cars) that the closer to normal temperature the quicker the increase.

Again after about 10 minutes pressure started to pick up although temp was about oil 60F. So I diluted a third time to bring pressure down to 80lbs again (green) and waited until the engine had been idling for around 30 minutes altogether. Oil temp refused to raise above 65F, which is still below normal operational temp and pressure started to raise again but not above 100 lbs.

If my life were depending on my engine running smoothly and not getting seizing-up or blowing a gasket ... I'd look for another line of work ;)

Other than the above I haven't really noted any issues with engine runnig, but I'm still just a ++noob :joystick:

EDIT:

UPDATE to this report. The temperatures should all be "C" not "F". During normal flight at sustained settings (2700 RPM/46"MP) temperature hovers around the upper edge of green, but pressure hovers on the red-line. It won't go above really, but it also won't go below.

This is NOT fixed. Following start-up procedures precisely results in a no-start situation every time. Either fix it properly, or change the start-up procedures to reflect the new parameters.

The oil bug is fixed. Something else might have been affected though, 'cause the engine is much more sensitive to incorrect priming now.

Is the oil pressure bug fixed for only the P51?

Loaded up a TF51 mission last night only to find it had skyhigh pressure still.

What mission was it? Just did a test, setting up a quick mission with TF-51 on spring map and the pressure did behave as in patched 51D - after startup, while keeping the engine below 1200 RPM, the pressure jumped only to 115-120 when cold, and dropped to green when warmed up.

Was a custom one. Loading and Saving in the ME seems to have fixed it.
