Well, after a massive oil leak, and an oil soaked timing belt I had my Talon TSi AWD hauled to a local shop where a friend of mine works. And they jumped to a quick conclusion that I need a crank seal, so crank seal got was still leaking and on closer inspection, it is leaking pretty steady from two different bolts on the oil pump housing......Is this a simple bad gasket job by previous owner, or a bad pump? Also, I can tell you that the motor has only about 3k miles on rebuild, with a "sit" time of maybe 3 or 4 years afterwards :( Also the valve cover started leaking within a day of my ownership (I bought it about 2 weeks ago) we tightened it down, it's fine.....Do you think by it sitting idle for so long that some of my gaskets are crap? Also, I'm not sure where my oil pressure gauge should be at (My eclipse rs doesn't have one) But I can tell you it was holding at halfway on the gauge and then falling slightly at operating temp. Is that where it should be? Sorry for the long post and thank you for any speedy replies, because me and my mechanic are almost at a stand still and don't want to replace a gasket and then have to do it all over again.....Thanx

It sounds like a bad gasket seal. Its only 4 bolts to take off. Take it off clean it up use high temp rtv. Its unlikely the housing is bad. Maybe possibly something is clogging it clean it out before re-installing. The oil pressure works with the rpm of the engine. mine at idle is low then when I take off it goes up to about half or more depending how fast im crusing. hope I helped

Take a picture of were it is leaking so we can see and better help you. If you are talking about the oil pump itself it does not use a gasket or sealant. Now if your talking about the front case then that's different. It Sounds like a bad gasket or you mechanic failed to clean the mating surfaces well enough. They need to be spotless and oil free. Use an oem gasket and torque to the proper value. You do not use rtv on this job, save it for your oil pan.

Agree'd, keep the rtv away from the front cover and oil filter housing. It will cause more problems than anything. I would pull the front cover and see what is going on with the gasket. You can get a felpro gasket set with all the gaskets and seals for like 20 bucks at the parts store.
