Oil Change Question

I have a dozen Fram C3s on the shelf, per this forum and few P203s.



When I change the oil and filter, how much old oil should I expect to stay in the filter case? I am changing the oil and filter again to help get more gunk out after just running the engine at idle for about 20 minutes.



When I first changed the oil when I got the car, I dropped the pan, cleaned out the sludge, gently sprayed the pick up to clean it, sucked out all the oil in the filter case and wiped it out as well.



But it just occured to me that there was some oil in the filter case. I thougth is would drain back into the pan. Unless I am not following the flow throught hoses correctly.



Anyway, I did not find this question to have been asked before here and it is not covered in the Mechanical Proceudre Manual (amount of oil left in the filter case, that is).

    Answer is: about 1/2 to 3/4 inches. Most of it is from the filter as it drips before one pulls completely out. Also, some sludge could be there.

    gosh, I'm getting confused, are you answering your own questions? or is this a Dr. Jeckyl/ Mr Hyde deal? :p



    I know the oil filter leaves a bunch behind. it should all be clean oil, already filtered though, if memory of the flow pattern is correct... high pressure thru the bottom of the canister, exit thru the side line.

    I know, I know.....I got very curious and went to the garage and pulled the filter in prep for the change and checked.



    Until I get the engine apart (not needed right now as it works, no leaks and good compression), I figrue it will take about 3 more changes to get most of the old gunk out.

    In the old days of cartrige filters, mechanics would use a suction gun to remove the last bit of oil from the cartrige housing. Following that a wipedown with a clean lint free shop rag finished the job. Suction guns are still available at auto supply stores,or barring that you can use a turkey baster, just get the wife a new one. the turkey baster also works well for a brake fluid change out. It will get rid of most of old fluid, so you fill with fresh brake fluid and spend less time to bleed out old fluid. That is one thing that is neglected on cars old and new today!!!, with master cylinder up in the open it is very easy to check, dark brown to black should be changed Lou Cote

    Thanks, Lou. I appreciate the service tips.



    I found a 3 gallon pump unit at Tractor Supply Company. It is "designed" for changing oil from the dip stick. I did not buy it yet as I am still unemployed. I think it will do nicely for changing clutch fluid and getting all that oil from cartridge housing.



    I have used the Turkey baster methode for brake fluid just as you described in another vehicle I had. It helped reach back to the firewall (one of the mini vans that had afew things tucked way back).

    my nieghbor has one that i borrow it is the size of a grease gun witha 18" hose and a handle in the other end. you just stick the hose in pull back the handle and it sucks the fluidout. push it back in to expell the fluid. works great for removing and adding fluids. holds about a pint and reachs anywhere. hudsonly walt
