Pumping unburnt gas from left bank. Quite a bit of gas will go through this head when running.

Hi Dennis,

If you have unburned fuel coming through then you have a misfire, valve issue, or over fueling condition.

I would suggest with starting with pulling codes. See if you have any and we can go from there. I assume you will have some misfire codes which will at least limit it down to a couple of problem cylinders.

Then just run some baseline information like compression and leak down. This may illustrate what the issue is or at least cross it off the list. Either way we need to confirm we are starting with a sound engine.

Let me know what your codes are then your compression readings are and we can go from there. Could just be a couple worn spark plugs or it could be more serious. Thanks.
