I was returning home from the next city when I discovered I had dropped the oil filler cap off my SOHC 1985 Corolla.
The engine compartment was liberally covered with oil.
I packed a bread bag into the opening to stem the flow.
Apparently, a tail from the bag reached the cam and the engine ate it as I continued on my way.
As I approached home and the engine slowed, the oil light came on and stayed on below about 2000 RPM.
The oil level was only 1/2 qt. Low.
I removed about 1/4 of the bag, which was wrapped around the shaft.
I couldn't find other debris under the valve cover.
I drained the oil and didn't see anything in it.
I haven't tried straining the oil, yet, but I wouldn't expect to find more than a few flakes.
I couldn't see anything in the spin-on oil filter and blew air through it from my lungs.
In think the likely next step would be to remove the pan.
I would rather not, if it could be avoided and that is my first question.
Is there anything else I should try or check before removing the pan?
I wondered if the passage to the pressure sensor could be blocked.
I don't understand perfectly how the oil circulates in an in engine, but I intend to study this.
I expect to find most of the remnants from the bag on the oil pickup strainer.
I thought if I drop the pan, I'd also remove the pickup and thoroughly clean the pickup and exposed parts of debris.
And also clear the drain passages between the the valve train and the pan.
But, I'm eager to read your reply before I continue.
