Hi,
I've got a 1954 plunger A7 fitted with a 1948 long stroke engine. It has been running pretty well but I've noticed the right hand exhaust is smoking a bit and a wet, milky discharge is coming out of the right hand silencer. Can anybody tell me what this is and why it's happening?
Thanks in advance.

PS Has anybody got a 53 or 54 plunger short stroke engine for sale?

Is this with a fully warm engine?

Warmish, the engine had been running for a couple of minutes. The left hand silencer is dry as a bone, yet there is a wet, milky deposit in the right hand silencer.
There are no odd noises and the engine sounds sweet as a nut

I can only think of condensation water emulsifying with some oil. The other side may be running hotter/cooler.
