saburo_cz Posted December 4, 2014 Share Posted December 4, 2014 Immediately after engine start, oil pressure looks like to hight. I don`t remember too hight value from previous DCS 1.2.11 When I started mission in flight, oil pressure was out of idicator range (temperature was slightly above 40dgrs) and when oil tempereture reached operation scale, oil presure decreased but was still above green scale? in fact I realized this during on line game and check it during of line, pictures are taken from of line game with "default map setting" in mission editor On ground after engine start, see pictures bellow for exact engine setings F-15E | F-14A/B P-51D | P-47D | Mosquito FB Mk VI |Spitfire | Fw 190D | Fw 190A | Bf 109K | WWII Assets Pack Normandy 2 | The Channel | Sinai | Syria | PG | NTTR | South Atlantic F/A-18 | F-86 | F-16C | A-10C | FC-3 | CA | SC | Link to comment Share on other sites More sharing options...
Mike Busutil Posted December 4, 2014 Share Posted December 4, 2014 (edited) That will happen if the engine is cold or also if the outside air temp is cold (which will take longer for the engine to warm up). Use the oil dilute switch next to the fuel pump to help bring it down into the green. EDIT: Wow, I have never seen the oil pressure read that high...

Cpt.Rookie Posted December 4, 2014 Share Posted December 4, 2014 Definitely something that 1.2.12 brought up. Even when engine is properly warmed up, oil pressure is still too high and it is impossible to keep it in the green area. Link to comment Share on other sites More sharing options...
sobek Posted December 4, 2014 Share Posted December 4, 2014 (edited) At first sight, there appears to be a bug in the modelling of oil viscosity. Edit: This is definately a bug. Reproduced and reported. Edited December 6, 2014 by sobek Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives!

Mike Busutil Posted December 6, 2014 Share Posted December 6, 2014 I am seeing the same high oil pressure in my 51.

Tumbleweed Posted December 6, 2014 Share Posted December 6, 2014 I've noticed it too however I've not flown the stang for a few months so wasn't too sure. I do seem to keep blowing up the engine a LOT even though I'm sure I'm as gentle as I used to be. Not really exceeding 2600 RPM and between 30 - 40" MP for cruise / pleasure flying. Just seems like the engine blows at every little thing..... Maybe it's me and lack of practice and has nothing to do with the high oil pressure?

Art-J Posted December 6, 2014 Share Posted December 6, 2014 And there I was wondering "why after the patch is my engine cranking soooo slowly on startup, even though I'm on hot summer map?".

flare2000x Posted December 7, 2014 Share Posted December 7, 2014 I have noticed this bug as well, after seizing the engine right after tak-off many times I figured out that it was the oil pressure.

MA_Goblin Posted December 7, 2014 Share Posted December 7, 2014 Also noted last Thursday and yesterday, the pressure reds at top of scale and even with warm engine doesn't drop that much. Hard to start the engine even in summer temperatures.

saburo_cz Posted December 8, 2014 Author Share Posted December 8, 2014 Hello, I checked it with TF-51D, "default" map seting in editor and: for 1300RPM after engine start oil tempr. 30dgrs -oil press. 150lbs oil tempr. 40dgrs - press. 160lbs oil tempr. 45dgrs - press. 178lbs Seems like opposite behaviour for both P-51 and TF-51.

Solty Posted December 9, 2014 Share Posted December 9, 2014 (edited) Definitely something that 1.2.12 brought up. Even when engine is properly warmed up, oil pressure is still too high and it is impossible to keep it in the green area. I agree, also startup is very long after this patch. Have you noticed that the engine now takes quite a while to start spining the prop? Around 15sec and before that patch it was instant.:joystick: Good that it was reported. I hope it will be OK after next patch. Edited December 9, 2014 by Solty [sIGPIC][/sIGPIC]In 21st century there is only war and ponies.

DragonShadow Posted December 31, 2014 Share Posted December 31, 2014 Glad to see this has been confirmed as a bug. The engine on the P-51D seemed to need a lot more effort in spinning up, and for the first half of my practice flight I was fully expecting it to give out at any time. Meter was consistently showing 150-200 oil pressure on DCS 1.2.14 on the Aerobatics server today, but otherwise performed OK. Link to comment Share on other sites More sharing options...

NakedSquirrel Posted January 4, 2015 Share Posted January 4, 2015 Gav, it may be because the starter overheats since it takes the engine a lot longer to catch now. A trick to starting the engine with the latest build is to hold down up primer switch after the engine starts to ignite. This seems to be enough to get the engine to catch every time for me.

piXel496 Posted January 4, 2015 Share Posted January 4, 2015 Is this bug also why I cannot restart the P-51 after shutting down for a repair? Had the same thought, but apparently your battery is drained after a repair. Ask for ground power and it starts immediately :) old stuff I made Link to comment Share on other sites More sharing options...
gavagai Posted January 4, 2015 Share Posted January 4, 2015 Interesting ideas. I thought it was the oil pressure. It's even higher after you land and switch off than when you initially spawn in! So, after doing the repairs, I held down oil-dilute for about a minute, and then the Mustang started up fine. I'll try the battery, too.

Shadylurker Posted January 7, 2015 Share Posted January 7, 2015 I logged onto Dogs of War last night to fly. I couldn't get the P51 started! while people around me got going no problem, It wouldn't even auto start with a new plane and everything. Link to comment Share on other sites More sharing options...
Art-J Posted January 7, 2015 Share Posted January 7, 2015 I've never used auto-start but I can only guess the script is very simple and it attempts to prime and crank the engine for x seconds, then switch the mixture to run. If that's the case, the script will obviously not "know" that engine oil viscosity got bugged and it will not work correctly. Right now it seems that starting the engine can be quite reliable as long as you don't forget to use the oil dilution for a while, maybe not exactly 2 minutes as manual suggests, but half a minute already improves the situation somewhat. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

Zompa Posted January 7, 2015 Share Posted January 7, 2015 Lately I just hold the prime for 4-5 seconds and then try turning the engine on. It's been working for me. Though it'll take about 5+ sec for it to want to "cough" but once it gets to that point it's good to set the mix to run. Link to comment Share on other sites More sharing options...
