Engine oil leaking from exhaust manifold

[7810s]

I have engine oil leaking from the exhaust manifold. Any ideas what could be the cause. It seems fairly constant and running down the side of the engine.

Valve guide seals. Especially if it happens mainly on light engine loads.

Turbo's gone .

If it’s running down the side of the engine is it actually in the manifold as it should be going to the exhaust? Is it not the rocker cover gasket, head gasket or even a porous or cracked head?

The oil is coming out of the exhaust manifold. I reckon it's only coming from one cylinder.

Is it worked hard? It’s passing the rings, valve stems, or head gasket. Have seen them pass oil after fitting new rings in worn bores but they settle after some hard work.

Not been worked hard recently. Been on hedge trimmer over winter. How could I find out the exact cause? The engine has done nearly 10k hrs.

Give it some hard work first just in case it clears it

Are you shure it oil and not fuel. We had one injector tip break off the engine ran but smoked a bit and fuel leaked out between the block and manifold

 

[7810s]

It looks like the oil has been leaking for quite a while. Unfortunately don't have any hard work I can do at the moment and need to move the tractor on.

It’s not the 7810 in your picture???

Its hard work it needs! Top gear, heavy trailer and steep hill required. A morning up and down Portsdown should cure it!

Kill or cure hey

Kill or cure hey

, certain to work, wont blow any out if seized! Though I have read several times on instructions for fitting liners, that the engine must be worked at around eighty percent of full load on completion to bed in the rings.I have an example, Perkins in my Leyland 253 always had a damp oily exhaust as it was not worked quite hard enough by the plough. One day, in an emergency, it was pressed into farm work, and a lad was sent of to collect the baler and sledge. There were some hills on the route, and I dont know what he got up to, but the white coating was burnt off the new exhaust, it had got that hot. Exhaust is dry now though!

Steam clean & sell it

What tractor is it? Have you a dealer close by with a dyno? A few hours on it should sort it. It's most probably glazed bores with doing light work

 

[Pennine Ploughing]

take it to a local dairy farm, put it on the slurry whisk, give it what for full throttle, sit in cab watch temperature gauge, so not to boil it, about an hours work, that will dry it up,
or local dealer with dyno will do the same

 

[Ley253]

Good idea John, love the "Whisk" term!

Dragged a trailer about for a bit this morning. It's pretty well sorted it out now[emoji41]
