Greetings,
First time posting. I have owned an L3250 for about 4 years now. Despite a few issues the tractor always starts right up and until 2 weeks ago have had No power related issues.
A BIT OF HISTORY:
From day 1 the tractor has always puffed gray w/ a hint of blue smoke.
I also noticed that after a fresh Amsoil oil change the engine runs quiet for only 10-20 hours or so then the lifters and general engine noise begins to creep back in. Not a mechanic but I recently adjusted the valves and was able to quiet them down a bit but can still act up. Assumed firing order was 1-3-4-2. I adjusted cylinders 4,2,1 and 3 when cylinders 1,3,4 and 2 were at end of exhaust start of intake. Found video describing sequence.
Suspect possible of oil dilution?? That would explain why the engine oil doesn’t seem to protect for very long. However I don’t ever smell fuel in the oil. The oil level doesn’t change and the oil never looks dirty - the previous owner old-timer told me he rebuilt the engine block (ie: sent the block out) but something seems fishy (blue smoke/noisy engine??).
No coolant issues whatsoever. Engine can eventually heat up to almost half scale. My diesel fuel tanks are always pretreated with extra fuel conditioners, injector cleaners, lubes, octane boost, and anti-gels. I’m like a bloody chemist at the gas station with all these additive.
HERE’S THE MAIN PROBLEM:
About 2 weeks ago I thought to myself maybe if the injectors were dribbling some of the fuel could be getting to the crankcase and diluting my oil and also causing some of my smoke problems so I decided that I would pull and clean my injectors. But before pulling the injectors I decided to pull off the exhaust manifold to determine which Port was smoking.
Well it turns out that the two middle ports are smoking the worst and dripping black oil or fuel out the port. The outside port is smoking much less and the inside port looks perfect.
Pulled all 4 injectors, did a quick clean, tested each port with injector (confirmed spray pattern) and reinserted my injectors. Bled the injectors with the bleed valve only and could not get the tractor to run right (loss of power). Purchased and installed 4 brand new injectors bled them with the bleeder and bled from the top of the pipes (found video last week) until fuel was pumping out then reconnected injectors. Started up and got same exact results - loss of power??
Filled new fuel filter with seafoam. Bled, soaked and ran tractor around the yard pretty hard for 30 + minutes. No change?? its like one of my injectors is not firing right ?
I ordered an injector pop tester to confirm good injectors. Great thing to have but I really don’t think I’m having an injector problem??
Do you think I still have air in lines?? I must be missing something here right ??
And to think, I caused this when I pulled the injectors.
God forbid what’s going to happen when I take the head off to figure out the bigger blue smoke/dripping exhaust problem? Probably not going to see a rebuilt engine block.
Thank you for any help you can provide.
