I have a 28 hp Lombardini engine on a Predator P28, the engine has done 600 hours and is basically worn out beyond practical repair, so I am having a new engine fitted. This will be the third engine on this machine, the first engine sucked in some soundproofing material after 30 hours which made the engine overheat, fortunately, Lombardini replaced this engine free of charge.
The present engine has sucked in dirt through the air filter, it has an oil bath air filter which I am told is the best, however, dirt has still entered the engine and caused wear that is beyond practical repair. I regularly check the air filter and to be fair in general it doesn't seem to get particularly dirty. However, I carried out a particularly dusty job a few months ago when I was grinding out a very old hedgerow and I believe this is where the problems started.
The engine started burning excessive amounts of oil, probably a couple of pints of oil an hour! The engine is actually still under warranty, but it seems like I will have to pay for a new engine as this is classed as poor maintenance. I do clean the air filter regularly, however, it is clear that dirt has entered the engine.
My question is; is there any way that I can get a new engine under warranty or insurance, thoughts appreciated.
Incidentally, I had the same engine on a Carlton stump grinder and this engine was also replaced under warranty, due to a faulty casting on the block. I don't seem to be having much success with Lombardini engines!
