This is a major drag for sure.. sorry to hear you are having this problem.

Obviously someone did not lube the rubber seal before putting the filter on.. remember it's stuck because the rubber seal is compressed against the machined surface..the filter is not stuck on the threads.

A few things you can try.. single sided razor blade run around the base as best you can..to break the seal.. or a thin bladed screwdriver.. be careful and try to avoid scarring the machined surface.

A band or strap wrench.. you may need to use sandpaper between the band and the filter.. to get extra grip

A large pair of C shaped pliers..

The last step is to drive a screw driver through the filter and reef it around.. very messy.. at some point you will expose the filter holes in the base of the oil filter.. and you can place a dull chisel,punch or screwdriver in one of these and use a hammer to drive it off or break it free.

Make sure to clean that machined base to ensure that no tiny pieces of the old filter seal remain. Very important to do this.. if that surface is not nice and flat.. chances of a presure leak are greatly increased and could happen within moments of first run.. days or weeks later.. and it's a real mess... not to foget the potential harm from loss of oil.

A little silicone grease or even clean motor oil on the new filter seal before applying will be a step I am sure you will never forget. Sorry to hear you had this problem.. extremely frustrating to say the least.

Best of Luck!

This probably goes without saying, but make sure youre going counterclockwise.. you probably need a better oil wrench, but at any rate if you could find a small piece of pipe to put over the oil wrench handle to make the handle longer to give you more leverage, that would help .... if not, try taking a long screwdriver and knocking it through one side of the filter and out the other and then try to use the wrench and the screwdriver to loosen it.... use a hammer to hit on the wrench handle or screw driver to break it loose if you have to..your filter is already toast and it has to come off so you will have to do whatever you csn

How do you remove a oil filter cap when its stuck?


First make sure you have the right tool to remove it and try again and make sure you turn counterclockwise (yeah.. it happens), then if it is a plastic oil filter cap you can try to heat it with a hair dryer , it should do the job. Plastic cap are not supposed to get stuck ; or it was dirty when put back, or the O ring broke and the cap got stuck, if you can't take it off at all have a quick run to the garage they'll remove it for you.

How can I fix cross threaded wheel screws?


Go to the auto parts store and borrow a nutcracker. Attach the nutcracker to the stuck nut. Tighten the nutcracker with a rachet wrench until the cracks completely in half. Now you can remove the wheel. Buy a new wheel stud and lug nut. Your lug nut will be pressed into a metal piece. Remove this piece and either 1) support the metal piece, put a good amount of penetrating oil on both sides of the bad lug nut and tap firmly with a large hammer. Let this sit for 5-10 minutes so that the oil can penetrate the stud. Now pound out the old lug nut with a large hammer. If it will not budge, then you can try heating the stud with a torch until it is quite hot and then hit the stud progressivly harder until it comes out. Now insert the new stud and pound it in until it stops moving. Last, before you reassemble, put the lug not on the new stud and tighten it real good to make sure that the stud is comletely seated. 2) the other option is to take the metal piece to the parts store and let them remove the stud and press a new stud for you.

Cannot get the oil filter off


It will come off, some times the oil filter is torqued on there with a wrench, when it only needs to be hand tightened. use a strap wrench made for that size oil filter, turn counter dockwise to loosen or to the left, if there is not enough room, you may require a cheater pipe on the handle to give you that extra
torque to remove it. good luck!

Changing the oil and filter may cure your problem if it has been a long time since it was done, and is certainly worth a try. Make sure to dump the oil into a clean container and look for metal (tiny filings are not that big of a deal, as normal wear and tear will produce them.) look for larger pieces and check the filter for pieces, too. If you find any amount of metal, it's time for an overhaul/replace.

Oil filter leaking


when you remove the filter, make sure an old rubber gasket isn't stuck on the mating surface, then check the mating surface where the oil filter goes for any imperfections or burrs in the metal that would cause a small gap in the seal when the filter is on.

Oil leaking from the gasket on the metal piece under oil fltr


Make sure that the oil filter is tight. Usually they only leak if dirt was in the gasket when the filter was installed or the filter wasn't tightened enough.

Front brake rotors wont come off when tapping with rubber mallet.


Did you take off the complete brake and caliper system?.  If so wrap a towel around it and gently tap on it with a rubber mallet, careful not to hit the metal with the mallet.  If it is still reluctant to come off, try a little penatrating oil on it.

I'm currently installing my 3 replacemnet Turbo


There are a few different things that will cause you to destroy turbos. It is very important that when you change the turbo you also change the mesh filter inside of the banjo bolt in the oil feed line to the turbo. This filter tends to get filled with sludge if you are not changing the oil enough, using poor quality oil, or if your turbo has gone bad, metal get stuck in this filter. Also make sure there is no metal pieces left in the oil feed line or any where else in the system.

You may also want to look into getting a turbo timer. This will give the turbo adequate time to cool down after driving, reducing the chance of warping the turbo.
