Oil filter

[edvanland]

on a 8V92 can you change just the filter without draining the oil. I changed the oil 2000 miles ago and discovered the oil filter is leaking. I am going to try to snug the filter down to see if that will work, if not then I will change the filter. Thanks for any thoughts on this.

Yes you can change the filter without draining the oil. Just top off to replace the oil that was removed with the old filter.

Ps. Make sure the oring comes off with the filter and does not stay stuck to the mount plate. Two orings in there will not seal properly.

There is no oil flow or pressure if engine is not running. Your filter is a spin on? Be sure old filter ring didn't stick to casting causing a doubling of gaskets. If it has steel canisters, make sure the old flat gasket was removed before installing replacement that comes with  insert filter. That type uses a long bolt to secure and should be tightened with torque wrench. By hand, and it usually isn't tight enough. Back to spin on; try giving it another 1/8 the turn, 1/4 at most. Some times filters can leak when cold weather hits and oil is stiff with high pressure but were ok before. If tightening doesn't help, try another element. Of course, make sure leak isn't above or behind filter and running down it, making it looking to be the source.

I pre fill the filter with new oil before I spin it on

Some folks claim oil never wears out.  They only change the oil filter on a regular basis. I am not that much of a believer and don't want to take that chance, but they change their filters all of the time without draining the oil.  I am not sure if they pre-fill their filters with new oil or just use the same old oil that comes out of it.  To me, oil is pretty cheap insurance so I change mine every now and then whether it needs it or not.

Ed-- everyone is warning you about the old gasket sticking to the filter base.  That is probably the problem.  Or is really loose!

Thanks all. No I made sure the old o ring was not left on. I was able to get under and turn it almost a full turn so now will wait and see what happens. Gary I always change oil on a regular basis on all my vehicles.
Thanks

Thanks

for most filters that would be over tightened ....

The "wearing out" of the oil itself is not the reason for regular oil change intervals, but rather the breaking down of the additive package and the introduction of foreign material into the oil through component wear, moisture, dirty air ingestion, etc.

Well finally got the time to run Greydog up on blocks and then pulled the filter. Made sure the old O ring was off and then really cleaned the surfaces where the O ring fits. Checked for any sign of damage and then reinstalled a new filter, tightened it by had, as recommended, and started it up, no leaks so it just had gotten to be a loose filter and the seal must have gotten damaged. Could not see any damage to the old O ring but I am happy.

Glad you are happy Ed.  I love seeing happy faces in Quartzsite.

When changing a spin on filter, prefill the oil filter with fresh oil before spinning it on. It takes several seconds for the oil filter to fill with oil and for the engine to get oil pressure again once you start the engine. Good Luck, TomC

Also take a little bit of oil on your finger and wipe the gasket so it isn't dry, keeps it from sticking/ripping when tightening it.

[edvanland]

Yes I did prefill the oil filter and I did put fresh oil on the gasket so it wasn't dry.
Thanks
