P-40 engine burning out

[FuriousMeow]

Twice I used the P-40 on Wings of Liberty summer mission, and both times the engine started smoking and seized after climbing to around 10 to 12,000 ft. The coolant was always around 80, if not below. The oil was up to 100 or above no matter what I did. The temp gauge showed below 60 at all times. The oil was always hot, always above 100.

 

The first time I ran the engine at 2900RPM and 35MP in climb. I did this prior to the patch and could fly around for a good amount of time prior to burning up the engine. Now it takes until I climb to about 10000ft and then it smokes up. All temps are great except oil.

 

I figured something changed and the MP needs to be lower. So I set it to 30MP and ran 2900RPM. The MP needle started shaking at 12000ft, engine was smoking, and died shortly after.

 

While taxiing with the outlet cowl shutters closed, the coolant stayed very low. It wasn't even as warm as the ambient temperature or the radiator. The oil started off above 100degrees and came down slightly while taxiing.

 

I thought maybe it was Wings of Liberty, they had a winter mission that had contrails down on the deck and the external ambient temperature must have been the cold of deep space because even with everything closed my engine was still getting colder.

 

In QMB, however, still having the same problem. The P-40s engine just burns up. This time right after take off, I can't even get to 500ft before it smokes out. This is from parked. Maybe I need to let the engine warmed up from parked on a summer mission in QMB? I would think that the ambient summer temperatures wouldn't require much of a warm up.

 

It also seems that no matter what I do with the prop, it matches the MP setting. If I set to 32 or below MP, the prop sits at around 2900RPM. If the MP is advanced further, the RPM advances as well despite any change to prop setting. At 40MP, the RPM sits at around 35. I see the handle moving for the prop RPM to increase/decrease but nothing happens.

 

I'm more delicate with the engine than I was in 1.104 and it just falls apart. What am I missing? The gauges all look beyond perfect except the oil, and the way the RPM totally ignores my inputs but follows the MP. I just noticed also that regardless of my change to RPM input, it is actually above 3100RPM in a climb at all times when the MP gets above 32. And the MP also steadily climbs as speed increases so I have to back the throttle off as I'm climbing out. Seems odd, but maybe that's the way the Allison ran?

 

What am I missing and what changed since v1.104?

 

EDIT: There appears to be a totally different RPM/MP relationship when using "runway" in QMB vs "parked" in QMB. I know that the coolant is already at a higher temp when using runway vs parked in QMB, so maybe there's something buggy there.

There's definitely a difference between starting the P40 engine and the P40's engine already being started in several ways.

 

1) Coolant and engine temperature are far lower when kicking on the engine from the "already running." Granted I don't have engine warmed up, so I'll just have to warm it up. However, should the next two items really be reliant on warming up the engine? Especially the non-functional prop pitch/RPM adjustment?

 

2) MP/RPM are tied in parked start up, in runway startup, adjust RPM actually has the desired affect.

 

3) The engine burns out shortly after getting airborne from parked regardless of how much the engine is babied. It runs perfectly fine from runway startup. I wouldn't think a lengthy startup during summer time temps to prevent the engine from burning itself out would be required.

 

Even with engine warm up, as I accelerate the MP increases and I pull back the throttle but the tach is at 3300 RPM. Despite any input to reduce the RPM, it will not reduce. Compared to using the runway option, where I could reduce the RPM and not just the MP, there is definitely something bugged with starting from engine off on at least the P40. If not other planes as well.

I had exactly the same happen to me on Coconut's server. No matter what I did the RPM stayed pegged at 3100 and eventually blew up the engine. I saw the tech chat saying it was changing as I changed it with controls but the rpm gauge never did. (I didn't look at the cockpit handle though).  I flew a sortie on WoL without any problems so it seems kind of intermittent.

Seems like the RPM control is not working when starting from parked position. I also have this problem now.

 

It only happens when using parked position and without warmed-up engine on my end. I reported it on the Beta forum, might be worth a hot-fix, but i can't say.

Bug aside, if you run your engine over 2600 rpm, you are putting it into emergency mode.

I overcooled my engine on the ground after startup. Took a 5 minute break and came back to an overcooled engine. Engine at idle. Not sure of the cowl position. Not even a winter map.

I have problems with overcooled engine too on winter maps. Outlet cowl shutters closed, but still had problems with keeping it warm. And on approach it overcooled.

Maybe put it on "Lean Mixture" helps ?

I have never seen an engine running 2900 rpm inside the envelope Oo !!
