If you have a plugged oil filter will you have oil press?

If you have a plugged oil filter with NO bypass will you have oil press? Will the factory gauge show pressure?

What type of oil filter do you have. Most oil filters when they become plugged have the bypass valve inside. Unless your talking about the oil relief valve but that is after the oil filter. But either way you shouldn't see much of a pressure drop. My best advice is change the oil filter.

that is a negative... if the filter is clogged...it will go around it...however, it will though circulate all that bad oil in the engine which is NOT good for your engine...major problems will occur later on down the line...thats why you change your oil every 3 months or 3,000 miles... if you are unsure of your last one...get it done...

Thanks for the replys but I think I'm asking a different question. Is the port where the oil press sender is before or after the oil filter? If it was before then the gauge would read pressure ok but there wouldn't be any oil going through the engine.

If the pressure port was after the filter then the gauge would read no pressure.

So is the oil pressure sender before or after the oil filter?

The reason I ask is that I have a remote oil filter. I am concerned on the gauge reading ok pressure but not flowing properly.

Most of the time the pressure sensor is after the oil filter. I am not 100% sure on the explorer but it should be, for the fact you don't want to send dirty oil passed the sensor. I hope this may answer your question better.

After changing an oil filter it takes much longer for my truck to gain oil pressure on startup, which leads me to believe that the gauge is after the filter.

Thanks guys that is what I was thinking too. That answers my question and I'm not worried about my setup anymore.

it is after the filter....because you would want to filter the dirty oil first then sense the pressure...how it works is that the filter is like a resistance...you know...it goes thru it and then reads the pressure afterwards because that is how much pressure you will have going into the engine...you dont want the pressure before the filter...if that was the case then the pressure would be reading off on what is actually going thru the engine...so it wouldnt read quite accurately...
