oil filter replacement without oil replacement?

[BigMassiveDude]

well. normally i would replace both. I could not get the oil filter off with a crescent wrench around the plastic hex on the filter housing in my 2008 VW Passat FSI Turbo. I was under the car and had already removed the old oil, when i was unable to remove the filter cap to replace the filter inside. Thus i just added new oil so my wife can drive the car the next day.

Now this weekend i am buying the 16mm filter cap socket in hopes that this will break the hold on the filter cap from its housing without destroying either. However, i really don't want to drain the new oil a second time. I would just like to open the spicket on the filter cap to drain the oil from the filter and then remove the filter cap with the new socket, replace the filter inside and screw the cap back on and done. Is this possible?
That is it possible to drain the oil from inside the filter cap (using the drain nipple on the cap) without all of the oil in the engine coming out of that filter?

Alternateely, i could just drain the oil a second time in a clean pot and then reuse it since it is the expense stuff, synthetic and only has 100 miles on it since last weeks change out. The oil filter is located below the vehicule, tus my concern whether all the oil in the engine will come out if i don't drain the engin first before screwiong out the old filter?

any ideas on what may help to loosen this kind of filter? thank.s

I would just unscrew the filter cap and remove the filter and cap as one. Where the filter mounts to the engine is not lower than the oil pick up. Therefore, oil is not going to siphon out of the oil pan. You will lose some oil and it will be messy but it is doable.

How long was the previous oil in the crankcase that you just drained ? If it was less than 8-10k miles then just leave the old filter there for another OCI of 8-10k miles. Most oil filter, cartridge or spin-on, can be in service for 20-25k miles in a clean engine without problem.

Hi HTSS_TR.
Thanks for your reply. My concern is that i don't think the oil filter may have been changed. How do you know right? Just the other day i watched videos on Youtube where JiffyLube was not replacing oilfilters that customers paid to be replaced. It was an under cover program by a news team. One of the Jiffy lube people said, why bother to replace something that the customer has no waying of knowing it was not replaced....that is my concern. The fact that the filter cap will not come off with a crescent wrench makes me wonder if this filter has remained in place over several past oil changes. I had an oil change about 8,000 miles ago or last year at a Cadillac Dealership, and before that at a Jiffy Lube. I really feel these guys did not bother to remove the cover under the engine to get to the filter. thus i am doing my own oil changes from now on where i will know exactly what was done.
The other gentleperson that posted just before your post suggests there should be no worries about losing any oil in the crankcase or oil pan and that the only oil to be perpard to lose is the oil in the filter iteself? Are you in agreement with this? any ideas on how to proceed to remove the filter cap? Maybe some of that spray for rusted parts aimed at the right place on the filter to break the hold? I'm buying a 36mm oil cap socket win a bit and will try to use that in place of the crescent wrench to twist off the filter cap. Im being otld to twist the cap in a counter clockwise directior to remove it. do you agree? Thanks a million.

The filter cap and filter housing for that matter is made of plastic. You screw the cap off and remove the filter cartridge or what ever you call it out of the filter housing and replace it with a new cartridge or filter mediam for lack of better terms. Then you screw the cap back on the housing and your done.

The darn problem is the cap will not twist off using a crescent wrench on the 36mm hex shaped nut on top of th cap. I'm buying a 36mm socket in which i hope it will distribute the torque properly across the top of the cap to break it loose without breaking the plastic cap or housing for that matter. Do you have any advise on how to break the hold of that cap? As i mentioned to the gentleperson that commented below your comment, i have a bad feeling that Jiffy Lube and possibly the Cadillac Dealership both did not replace the filter even though i paid for it. See my comments why below. So my understanding is that you believe that even though the filter housing is located just adjacent to the oil pan on this modle car, there should be no overall oil draining comming out of tha tpan when i remove the filter? Tha i should only worry about the oil in the filter? Thanks a million.

I would wonder if they did replace the cartridge, that they also spun on the filter housing on extra tight (as many places are known to do for drain plugs and such).

I did a quick search on youtube and the looks like the process:



I would think that you'll have minimal loss with the removal of the housing, especially if you can figure out how to relieve the oil in the filter, maybe by pressing on the valve in the middle. Video also confirms that the housing is righty-tighty, lefty-loosey.

Another video shows the use of a pair of channel locks to take off the housing, but if you'll be doing this often long term, I would go ahead and get the big socket too. Again, if you'll be doing the service yourself long term, might be worth picking up that filter drain adapter too:

Edit:
I was perusing the amazon reviews for that drain tool, one of them suggested getting an aftermarket filter housing cover that allows draining a little faster: http://www.ecstuning.com/Volkswagen-Jett...sing/ES2804146/

Other reviews say that you can just jam a screw driver up there to let the oil out. I'm beginning to think that you'll definitely want to drain the oil from the housing before you do the filter swap, unless you want a fairly large mess on your hands.

Is this the same procedure for the 2014 1.8T gas engine? The housing looks the same. I was just going to put the hose from my oil extractor in there and suck up as much of the oil as I could.

The answer to your question is yes, there's not going to be 5quarts of oil coming out when you take off the filter housing.


If it's on tight,
one thing to try is to warm car up slightly: Like a min or two. Not fully hot that you burn yourself touching the wrong thing, but just to about body temperature.

Edward C..many thanks kind gentle person. I appreciate the support your providing with the links and the video. I just purchased a 36mm socket which is what was advised for the car. Before i use it though, i will take your advise and warm up the car for a minute or two. I will also drain the oil pan of the 5 quarts of new synthetic oil, which i'll be sure to pour back in once i am able to change out the filter element.

I will keep everyone up to date on the outcome. I intend to perform this step over this weekend. Thanks again Edward C.

RayTSeng...actually you suggested the warming up of the car before as well. I thank you kind sir. I will let you know how my luck turned out.

I took the vertically hanging upside down filter housing off my GF's Volvo while it still had oil in the sump. To my surprise, less oil came out of that compared to the spin on oil filter on my Jeep.
