Yesterday I did an oil and filter change on my 03 XKR. I used a Purolator PureOne filter...the same exact one I used at the last oil change. When installing the oil filter I noticed it stopped tight before going 3/4 of a turn. I experienced the same thing when I did the last oil change so I didn`t worry about it as I had no leaks last time. This morning I see I have a small seepage leak at the oil filter mount. My question is...can I spin off the existing filter and *quickly* put another one on without draining the new oil and without having 8 quarts of oil flowing out onto my driveway?

 

I would give it a "small" tighten (1/8 turn?) before I replaced it. Can't hurt if you watch it.

Also did you prep the gasket with a drop or two of clean oil before you installed? This helps lock the seal to the block.

But I will say 3/4 of a turn is not normal. If you take it off, better check the threads and make sure it hasn't stripped.

 

I did lightly oil the gasket as always. I`m sure the threads are not stripped, and I`d be afraid of stripping them if I tighten any further. I hand tightned it and it stops firm like it is at the end of the thread depth. Do you know if all the oil will come gushing out if I try to replace the filter without draining the oil?

 

Maybe not gushing out as from the pan, but it will come out. It will be messy and difficult to put the new one on. Never tried it this way, but it should be do-able. Have a clean (new) pan ready to catch the oil if you try to reuse it, although if it is not too much I would just dispose of it.

Someone else may chime in here with more knowledge, but I'd be concerned about the 3/4 turn limit on tighten. My '01 takes multiple turns before it begins to tighten. Hence the name spin filter. Otherwise your next filter may have the same issue or worse.

 

I actually mean 3/4 turn *AFTER* the gasket first contacts the base....sorry I should have been more clear!!

 

You'll have a similar amount come out as you have when you do an oil change. The oil is in the pan at a lower level than the filter. That's why it's important to use a filter with a non-return valve so it doesn't drain back into the pan as the vehicle stands.

Two possibilities come to mind:

1. faulty oil filter thread
2. oil filter adaptor (arrowed in red) is loosened or threads damaged



Either way, the 'problem' filter has to come off.

Did you check to see if the previous oil filter left its rubber gasket behind when you removed it? It's rare, but it has been known to happen....

 

Good point about the gasket, but that`s not the problem. I had that happen to me once years ago and ever since I check that the gasket is still on the old filter (when I started the car all the oil ended up on my driveway). I think it`s a design problem with the filter. Thanks......

 

I have had a Purolator Pure-One Jag filter bottom-out prematurely once also (although it turned a bit more than yours and did not leak). I say use a different brand filter.

 

I have a slight leak in the same area. I dismissed the oil filter as I have never had that problem. My guess was the leak was at either the oil pressure or oil temperature sensors, but they both seemed OK. For now I will live with the leak and the next oil change will check the oil pan adaptor and make sure it is not backing off.
