So, a regular old filter change on my F150 went bad. Gasket stuck on the filter mount, new filter went on, with - two - gaskets. Tightened the filter up, started her up, oil pressure gauge read normally. Every other time I've changed the filter, I check for the gasket - but for whatever reason, I didn't this time (I was BS'ing with the neighbor while doing the change).

I finished up at night and drove it up and down the block, no warning lights (again, it was at night, so a warning light would have been obvious).

But then, when I pulled back into the garage, I noticed a pool of oil on the floor (not much - maybe 1/8 qt). Looked up under the truck, removed filter, found two gaskets... replaced with another fresh filter and ONE gasket. (and cleaned the driveway - that was the most aggravating part...)

I know I'm being worrisome, but I'm wondering if I could have done any damage by running the engine for 30 seconds up and down the block? I don't know the layout of the oil system on this engine - ie, does oil flow from the pump to the filter to the engine, or from the pump to the engine to the filter? I assume if the pressure dropped low enough to do any damage, an idiot light would have come on - no lights. Everything runs and sounds totally normal.

 

well how much oil is in the truck? the pressure wouldnt have dropped unless it blew all the oil out.

 

30 seconds at what 15-25 mph no worries no issues just because you drained the oil, it still has a film in the engine to protect it at startup so I think you are pretty safe

 

Well, I checked the stick before I started it, right at the full mark. After the (second) filter change, it was only down about 1/2 way on the OK area of the stick. 1/2qt took it back to full. There is no way there was 7 quarts of oil on the ground. 1/4 quart, maybe.

 

I think it is safe to say you are alright.
Do you put a lightcoat of oil on top of your rubber seal before you put your filter on, as it will usually stop this problem

 

yea your fine, no problem!

 

Always have, always will - this is the first one I've ever had stick.

Heck, I didn't evan start checking for a stuck gasket until I read some horror stories about fires on CR-V's last year.
