    Cat 951c engine, oil in exhaust manifold

    Hi guys . It took me 15 minutes. They are 4 bolts, spanner 24. Below there are about 10 bolts, wrench 14. With the electric unscrewer it took me very little time. It seemed like a challenge to lift the engine, but it is really easy. Of course, considering, removing the underlying plate, oil, oil...

    Cat 951c engine, oil in exhaust manifold

    Hello I wanted to remember, that in order to remove the underlying plate is only necessary to unscrew four bolts which hold the engine side, two on each side. Then you have to disassemble the rubber biscuits. Not completely but only on one side (that of the converter) are 8 bolts. At the front...

    Cat 951c engine, oil in exhaust manifold

    Ho misurato i cilindri. Diametro sotto la cresta 120,69mm Ho trovato un modo per rimuovere la piastra sottostante. I pistoni, le bielle, le boccole sono davvero in ottime condizioni. È probabile che abbiano rifatto il motore senza cambiare i cilindri. Tutto il resto è nuovo. Basta guardare la...

    Cat 951c engine, oil in exhaust manifold

    When I clean the valves I expected a lot of coal. Instead, with the drill, a rust color came out. The residue I removed looked like sand-colored flour. Could it be dirty fuel? I didn't find any kind of crack in the valve guides. it is likely that something has entered in the suction phase, some...

    Cat 951c engine, oil in exhaust manifold

    Hi guys I cleaned the piston. It's new. it has a dent, I think something got in from the side of the air filter. For the rest I don't know what to say. I believe the cylinders are enamelled and the oil rings don't work. There is no crest on the cylinders.

    I removed the piston 2. It seems to me in excellent condition. The rings are like new. I have not found any anomalies. I think all that oil comes out of the valve guides .... I think.

    Cat 951c engine, oil in exhaust manifold

    Hi guys . In the meantime, thanks to everyone for the support. I removed the cylinder head. The gasket is like new. Before disassembling I eliminated the exhaust. I could see that the cough was coming out of cylinder # 2. During the strange explosion you could see sparks like fire. I could not...

    Cat 951c engine, oil in exhaust manifold

    Hi guys , here, I created a private video in hd. If you look at it all you can see and hear the strange sound of the engine. He seems to be coughing. I also framed the exhaust manifold and a few minutes already a leak. As already mentioned, no blow by even at full throttle. This makes me...

    Cat 951c engine, oil in exhaust manifold

    Hi guys , this and the 951c As you can see in the last photos, to remove the plate under the oil sump, it is necessary to lift the engine at least 3 centimeters to remove the bolts. Unfortunately . I did not understand the pin that should close the rocker arm shaft, from the oil spill. Where is it ?

    Cat 951c engine, oil in exhaust manifold

    it is clear that I have tested the engine: without exhaust manifold without valve cover without air filter I disconnected each of the diesel pipes (with the moltore on) It could be that the intake valve guides are very damaged and the oil passes into the combustion chamber. Hypothesis only...

    Cat 951c engine, oil in exhaust manifold

    I disassembled the oil cooler above the filter. it turned out completely clean. The system had a clean blue coolant. There is an oil cooler on the side of the water cooler, all clean. I must say that the system does not heat up and the indicators always remain on the green. My doubt remains. Can...

    slightly, but insignificant. I unscrewed the oil top-up cap at full throttle. It doesn't move at all, zero. What do you tell me ?
