I have a 95 sl2 that is leaking oil out the front crank seal and is registering no oil pressure

You don't give make or model. Here goes , The engine has a rear maim seal behind the fly wheel if it leaks the leak will be from the clutch housing. It has a front seal behind the crank shaft timing cover.it can leak from there . it can leak from the oil filter and oil pressure switch . Can also leak from the top timing cover gasket and cam shaft seals.

oil leaks from underneath can come from front crank shaft seal --rear crank shaft seal --oil filter--sump gasket---power steering ---leaking rocker cover gaskets ---leaking oil pressure switch.--transmission seals. I suggest that you have the engine professionally cleaned and then put it on a hoist while running to see where the oil is from

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.

External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.

Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.

Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.

Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

I think it helps to analyse u r Problem

Yes, I think you're right that it's the seal that is leaking.

yes its worth fixing.

a good mechanic will charge you between 3.5 and 3.9 hours labor to do the job properly plus parts.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

could be from the intake manifold or cam seal behind the timing cover. It's also possible
the valve cover gaskets are leaking or the front main seal is leaking. Might try cleaning engine with a good degreaser and see where the leaks originate. Good luck

your the only one that can answer where, check the oil filter and the oil light switch first.

check your pcv valve usually if it gets plugged it will blow oil out where it can.the pressure builds up in crank case thats the pcv valves job to relieve the pressure

Front cover or rear main seals

first of all do you know if your engine is a non-interference i would think a 95 would be non-interference ( another words the valves do not collide with the piston in the event of belt failure ) for the power loss issue i would suspect your cam to crank timing ( align timing marks )
exactly. as far as your oil leaks, as mentioned by another comment,
your seals, ie. rear main, front crank, and your cam seal would of been simple to do prior to stabbing the engine, except for the cam seal you now have quite a job, if you did the install. if you paid a shop
take it back. this is not even close to good business
