What are you asking for? Buy the right gasket, drain it, unbolt the pan, apply new gasket, reseal pan, refill. Or just go to a mechanic. Wont take them but an hour or so.

I don’t really know how to do to it exactly and I don’t wanna spend $590 at my mechanic. I just need some tips

Pretty straightforward. There are a series of bolts around the pan. Pull those, drop the pan, clean it up, put on the new gasket and put the pan back on. Het the bolts good and snug.

Just remember to drain it first. While its off look in the pan before you clean it to see if any metal is in it. Lastly use a finger in the old oil (if its clean enough) and lube the new gasket up good and check for old gasket parts or irregular places where it sits so it wont leak also. Same with a oil filter...pre lube it with old oil.

Ive never had a oil pan gasket leak or blow.

EDIT: Might want to check the manual or online and see if there is a torq spec for the bolts and if there is a tightening order for them.

If you don't find a tightening order, work back and forth to tighten the bolts, sort of like you would lug nuts on a wheel.

^^ Ya don't over tighten the bolts, you'll just cause a new leak. Don't under tighten them either because you will cause a new leak.

Use a torque wrench and tighten one bolt on one long side of the pan, then a bolt on the other long side of the pan in an 'X' shape. Keep doing this all the way around the pan (One bolt on on one side, one bolt on the other side in a criss/cross pattern).

actually, on my 2000 v6 3.8, ford put a subframe about a half inch underneath the oil pan. I wouldn't recommend droping the subframe unless you plan on doing an alignment. I had to disconnect my drive shaft, undo my torque converter, disconnect the motor mounts then jack up the motor with an engine hoist. The oil pan gasket is only RTV sealant except has a rear seal that goes in the back of the pan. This is a 6-8 hour job. I'm pretty certain this is the same for 99-04 vehicles.

It's a 96 but essentially the same configuration from 94/95 to 2004. Does not look fun....
