Two things come to mind; 1 the old rubber filter seal is still on the motor, or 2 the new filter does not have the seal on it.
oil leaking out of the muffer and the air filter oil leaking out of the muffer and the air filter oil leaking out of the muffer and the air filter oil leaking out of the muffer and the air filter
check that the O ring was replaced when oil filter was changed. id O ring is good and filter is tight, and housing still leaking, replace filter housing
Coulpe of things to look for. Not tight enough, they say hand tight By I put an extra 1/2 turn after hand tight. Old rubber seal from old filter was left on block. cheap filter. You may of pinched it while tightening the filter (if you used a filter wrench as I do
Oil filter? Oil pressure sensor?
Take the filter off and look where it mounts onto the motor to make sure there is not an old gasket stuck to it and if there is take it off and then put on a new oil filter hand tight, be sure to put oil around the gasket on the new filter before you install it.
Which filter housing? Air filter, oil filter, fuel filter?
my oil filter housing is leaking what should i do?
Valve cover gasket is probably leaking oil onto the exhaust manifold or the oil filter may be leaking oil onto the exhaust pipe.
Wrong size filter installed. The mounting surface was not wiped clean before installing the filter. A thin layer of oil was not applied to the filter gasket before it was installed. When the old filter was removed the old filter gasket was left on the mounting surface. The filter was either tightened too tight or not tight enough. Tighten it 3/4 turn after making contact with the mounting surface. No more and no less. The oil filter is defective and needs replacing. The oil may just look like it is coming from the filter when in fact it is leaking above the filter and running down the filter side. Most likely from a leaking valve cover gasket. My advice is to remove the old filter and make sure the old gasket is removed. Clean the mounting surface and inspect that surface, oil the new filter gasket, install the new filter tightening it 3/4 turn and start the engine. Let run for 30 seconds, shut down, wait 30 minutes. Check the oil level and add as necessary to reach the full mark. Probably will take maybe 1/2 quart or less to replace the oil lost when the filter was changed.
First U check ABOVE the filter 2 b sure the intake manifold & Valve covers aren't Leaking.. then U check 2 c if the mounting surface is flat & the threaded connector is tight & if that doesn't work U might need a new filter If after checking above, the filter, as Marv pointed out, you find that it is indeed the filter that is leaking, replace the filter. Clean the mounting surface throughly, oil the filter gasket, and tighten the filter 3/4 turn after it touches the mounting surface. No more, no less! A leaking filter is almost always caused by incorrect installation.
Remove the old filter. Replace it with a new filter. Before installing the new filter wipe the mounting surface clean and apply a coat of oil to the new oil filter's gasket. Spin on the filter and tighten it 3/4 turn after it makes contact with the mounting surface. No, more and no less. If you still see oil leaking from the filter then look above the filter for the leak. Possibly valve cover is leaking.
The oil filter may be lose.
