Went to change oil on my 97 quadrunner. Drained oil just fine, but went to take off oil filter cap and the one of the three nuts was stuck on. Got it off after an hour of huffing and puffing. Changed out filter, put cap back on, put two nuts on, but the last one didnt go on right. Started the engine, and immedietly oil started leaking out the oil filter cover. Shut it off and tried to fix, with no avail. I did notice that there is a gasket and a spring missing. Ordered all parts i could ever need for it off partzilla, and am waiting for them to arrive. If the stud is stripped, not the nut, how would i replace it? Thanks.
