Blue smoke at rotation speed

[Tomas Linnet]

Hi

I just had some kind of engine problem with my P51 civ. just as I was rotating I had blue smoke from the RH exhaust stack. quickly landed at the same airport, so we are both safe on the ground
I can see my cylinders 4 and 6 is a bit low on compression, but I cannot confirm that even numbered cylinders are on the RH side( seen from the cockpit). Can you?

You just gotta love Accu-Sim....

I found this: http://www.airpages.ru/eng/mt/merlin02.shtml

Here is the Cylinder numbering:
1A, 2A, 3A, 4A, 5A, 6A.
1B, 2B, 3B, 4B, 5B. 6B.

but how do I translate this into a 1 - 12 ?? I don't know it A is to the left or to the right??

Update:

looks like cylinders 4 and 6 is on the RH side of the engine

Hi Tomas.
Looking at the second link you posted , cylinders from front to back are left bank 7 to 12 right bank 1 to 6 , which would line up with your puff of smoke from right bank exhaust and your cylinders 4 and 6 being low compression.

exactly, I'm amazed on the level of detail A2A put into this. Keep them coming!!

The smoke will get worse as the engine wears too. Mine started out smoking at high power only, it now will start to smoke at 20-25".

Yes keep an eye on those and go the wear till dead route or start thinking about a quick hangar repair now/soonish.

cheers,
