Changing my oil today, when a gust of wind drops a little leaf right in the funnel. Before I can react, shwoop! It's down the funnel and somewhere in the valves.
I can't see it in there through the oil hole to fish it out. Am I condemned to remove the valve cover to remove it? (At least I have a spare valve cover seal on hand.) Is there any alternative? I presume it will harm my engine to turn it on with that #%@$ leaf in there, yes?
if it's big enough, it could clog an oil passage. It sucks, but I'd pull the valve cover and see if you can fish it out. Better safe than really, really sorry.
It really depends on the kind of leaf, the size of the leaf and what state of decomposition it was in.
Just kidding, I would play it safe and get it out. While I can't imagine that it would do anything beyond quickly getting cooked and turning into soup, it would be ashame if anything went wrong.
That's a Poignatas motorum mortem leaf, you do have to take her out as soon as possible! What are you waiting for?
After 48 hours their acidity multiplies exponentially giving out,sometimes something similar to LSD. Drivers behind your car may start driving erratically...
