A really dumb question - crankshaft pulley

[peterg1001]

OK, laugh at me if you will . . .

If I remove the starting dog, and pull the crankshaft pulley out, will the engine oil come gushing out or is there another seal around the crankshaft which will hold it in?

In other words, do I need to drain the engine oil before removing the crankshaft pulley?

Thanks, Peter

No, the crankshaft does NOT run submerged in oil, that is why your sump has a section below the crank area to hold the oil. Use your dip stick to gauge the oil height and you will see.

That ^^ and there is a seal called a crank main seal or thereabouts thats meant to stop the oil pouring out. Mine weeps. Damned dog is too hard to remove so it can keep weeping.

I put a big adjustable spanner on the dog, rested the end of the spanner on the passenger side chassis, made sure the ignition was off and turned the engine over.

No problems.

There isn't a main seal on the front of the crankshaft, instead the seal in the timing cover does the job,

There is no such thing as a dumb question:angel:

To summarise the answers above - The crankshaft is above the oil level, so you won't get a lot of oil out when you remove the pulley (but you will get some, as there will almost certainly be a little in the bottom of the timing case).
