Just a couple of questions from old curious Winston. What rpm do you normally operate at? Is your temperature gage getting up at least a quarter of the way? Certainly not saying it is the problem but just putting it out there as one cause is leaking injector.
id be willing to bet that there is water leaking in that exhaust from rain, unless its kept in a shed during all rain events then that shoots that one?
fwiw, it takes a while to get moisture out once its in,get it hot, if its not losing a-freeze it should improve as u use it-did u change the engine oil ? if not see if its real thin on the dipstick
Unbolt the Exhaust and move it so that it's pointing Fwd. You can also put a 45 deg. on so that it would be pointing downwards. That will keep water from getting in the exhaust while sitting and if it is Oil/Fuel Blowby you may get some on your feet.:2cents:
