3024ct

This is new to me so thanks for your patience. I have a stump ginder with a CAT 3024 ct eng. The machine is out of warranty with only 140 hours on it (I know -- use it more!). The problem is that it just started using oil EXCESSIVELY (1 qt. per 10 hrs.). The tube from the turbo to the intake manifold is dry, should I assume the problem to be the head gasket? I know this to be a weak spot on these engines. Before I buy a turbo or a head gasket (and accompanying gasket kit) I wanted to know what the pros thought. What do you all think?

My guess is the engine still isn't broke in, or it has sat enough that the rings aren't seating properly. Find some good solid oak, hickory or hedge stumps and work the hell out of the engine (without breaking the rest of the machine ).

How long is it sitting in between those 10hrs of work? My bet is that is when you a loosing oil.

The engine sits above the deck of the unit. If it were leaking, the puddle would be obvious -- it is not leaking. The unit operates flawlessly under all consitions. The oil is obviosly being consumed (or burned off), but you can't notice it in the smoke.

That is why I think the engine isn't broke in yet, or the rings need to be reseated. A fresh engine almost always uses oil til broke in, to some extent. Some more than others.

We had a new Deere 9320 4wd tractor. It used 1 gallon a day til it hit about 200hrs and we finally got a load heavy enough on it to break it in. Once it was, it virtually quit needing oil to be added at all til service time.

Gotta load that engine down some how, if the grinder isn't enough load. Get those exhaust temps up. Work that thing.

I totally agree. It kinda reminds me of guys having there tractors overhauled then doing nothing but feeding with them all winter. Seems like they always burn oil if they arent worked and broken in.

3024ct update

I noticed oil in the intake tube between the air filter and the turbo. The pcv vents into this area via rubber hose. I disconnected this hose and vented it to the atmosphere while I gound out 4 stumps. Within minutes pressurized smoke was exitting the tube and filling the neighborhood. The area of the engine under the hose was coated in oil. Back at the shop I pulled the rocker cover and turned over the eng. When cylinder 1 made compression, a puff of air was expelled from the area of the exhaust valve lifter. The point is, CAT confirmed this was a symptom of a blown head gasket. Removing the head confirmed the blown gasket. I am currently pleading my case to CAT for some assistance in covering the costs associated with the repair. I'll likely get no where, but I gotta ask. I'll keep you posted.

Huh a headgasket at only 140 hrs, thats not good. Our cat dealer can be good at helping out with warranty work, the mud drivers on our challenger ate the belts up premature and cat stood 2/3rds the cost even though the machine was out of warranty.

CAT agreed to cover 50% of the total bill. Half is better than none and since the engine is 2 years out of warranty, they could have told me to pound sand. I'm pleased with the outcome. The engine starts easier, idles smoother and maintains strong power under a load.
