First, what kind of vehicle is this on? Without that known, there is usually only two reason to have a leak at the oil filter:
1 - oil filter gasket itself, for one reason or another - if the filter gasket was not lubricated with oil before it was installed, or the filter has been on the vehicle for a long time, it can stay stuck on the vehicle when the filter is removed for an oil change - when a new filter is installed, the gasket on the new oil filter makes contact with the old gasket instead of the engine, and leaks - this is very, very dangerous situation because the oil can be lost in a matter of a minute if the old gasket breaks loose - the engine most likely would be ruined before you could get off the road if driving at 70 mph... Pull the filter off, make sure the old gasket is not the problem, clean off the sealing surfaces on the engine and the filter, oil the filter gasket with clean motor oil, and re-install filter - tighten 3/4 turn once filter gasket makes contact... If still leaking, install a new filter of different brand... 2 - if this is on vehicle that has an engine oil cooler, (usually an option or part of a trailer towing package) there is a o-ring at the oil cooler/filter adapter, where the oil lines going to the oil cooler are installed. The o-ring gets hard as time and heat degrades it, and starts leaking - sometimes, a lot... To fix, buy a new o-ring ($6 or so), remove oil filter, remove the bolt in in the center of the oil cooler/filter adapter, pull away from engine only enough to completely scrape out o-ring out of the grooves, install the new o-ring, re-install center bolt, and the oil filter. It is hard to scrape out the old o-ring, but a lot cheaper than adding a quart of oil after every trip... 3 - Always check for leaks when replacing the oil filter - even if there has never been a problem - only takes one time to have a mess to clean up, or an engine to replace... 4 - Check to see if the leak could be comming from the oil pressure sending unit, located above the filter on the 4.0 L, it leaks on the filter and runs off.
change your pcv filter and pcv sensor that pops into your valve cover
Sending unit has a leak. Just had to replace mine.
You unscrew the old filter, wet the seal on the new one with oil, and screw the new one on hand tight.
its very common for 3.1 to leak for distrib housing
The plug or sensor above the oil filter on a 1996 Cherokee is the oil pressure sending unit. This sensor controls the oil pressure gauge.
If the casing is spilt a filter will leak an incorrectly installed filter will also leak.
an oil leak
You can use an oil stop-leak product to stop an oil leak on your 2002 Peugeot 206 1.4.
use leak stop or something. Where is your oil leak?
The filter cap will be brocken and oil can leak through that way just change the filter cap
Purchase the correct size filter and make sure is is a premium filter such as AC/Delco, Purolator, Wix, or Bosch. Remove the old filter and throw it away. Clean the mounting surface and look at is closely for any scratches or gouges. If it is clean and not damaged, apply a thin layer of oil to the gasket on the new filter or it can leak. Turn the new filter 3/4 turn after making contact with the mounting surface. No more than 3/4 turn or it can leak. You will not have a leak if you do this.
It's in the area of the oil filter, wires going to it. Can leak but most of the time it's the gasket between the oil filter adapter.
you fix the leak
oil leakIt takes about 1 to 1.5 hours. I just replaced my gasket doe to an oil leak that appeared to be coming from the inside of the filter adapter. This did not stop the leak, I now believe it is coming from the gasket of the front engine cover that the oil filter adapter bolts too. this is a much bigger job. Bob
I wouldn't recommend it. Replace the gasket.
The old oil filter gasket might still be stuck on the engine block. Having the two gaskets in place will not allow the filter to seat correctly causing a leak.
Yes, it can be harmful. Use no oil treatment or stop leak at all.
