I was told that you could use marine's putty which I purchased from Home Depot, however, this only worked temporarily last season. I continued to have the leak and continued to get air which made it impossible to clean my pool. I replaced the filter this season and hopefully it doesn't happen again. Good luck.
If the casing is spilt a filter will leak an incorrectly installed filter will also leak.
If you use a test kit and your chlorine level is high I would say no, let the filter run and while the filter is running vacuum the bottom of the pool to remove some of the mud off the bottom of the pool floor and check the filter for high pressue, so the filter can do its job and get the pool clean. You want to keep your chlorine level above normal during the cleaning level so when the pool is clean your are ready to use it, also I do not know how brown or muddy the water is.
Oil filter installed incorrectly as in too tight, too loose, the gasket was not oiled prior to installation, or the old filter gasket was left on. It can also be a valve cover gasket leaking and running down by the filter. Replace the oil filter and oil the gasket and tighten 3/4 turn after it makes contact with the mounting surface. If the leak persists if is not the filter.
If its not closed properly water will leak out when the pump us running.
Check your fuel filter for leaks most likely that's the problem these seals go bad on the filter and it will leak while running
There is a fair amount of fuel that will leak when changing the filter.
Assuming this vehicle is fuel injected, you may have a vacuum leak or a plugged fuel filter.
Remove the old oil filter, check to make sure the old filter gasket came off and is not sticking on the mounting surface. Wipe the mounting surface clean with a clean cloth and inspect it for cracks or scratches. Apply a thin coat of oil to the new filter gasket. Install the new filter and tighten it 3/4 turn after it makes contact with the mounting surface, no more & no less. If you then have a leak and the mounting surface has no scratch in it then the leak is above the filter and running down making it appear that the filter is leaking when in fact it may very well be a valve cover that is leaking.
your fuel filter is rusted an have pinhole when fuelpump running it presure fuel filter and fuel leak thru pin´hole to eart.
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.
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.
