Where am I leaking oil from???

The leak is located above the bell housing, and I just redid the manifold gasket only to find that isn't the leak... It is leaking pretty bad too.

It isn't the distributor or the valve covers either... Is there some sort of oil ports on the back of my block above the bell housing?

And yes, I have tried to wipe it all down and see where it is leaking from, but the bell housing is in my way, and I can't see from the top either.

Re: Where am I leaking oil from???

That is a possibility, I mean it is leaking pretty bad though. Like a 5" puddle after parking.

It runs down from where it is leaking, to a big wiring loom, from there, it runs and drips onto the bell housing on the driver side, it then runs down the bell housing to makes a mess under my car and on the ground.

Re: Where am I leaking oil from???

Pictures might help. Your description was kinda confusing for me. But if its leaking a lot out the back of the block, id say rear main seal.
above the bell housing, might be oil pressure sender, maybe it leaks around the oil filter? might be your intake manifold or valve covers or distributer.

Other then that, maybe a hole in yer block? lol Only plugs in the back are for coolant if im not mistaken.

Back of the intake is dry. I just did the gaskets and checked them.

Re: Where am I leaking oil from???

Isn't the rear main seal under the bell housing? I know for a fact that the leak is about the bell housing.

Re: Where am I leaking oil from???

its the oil pressure sender fitting. mine was loose.. leaked like mad. it pools up on the lip the fitting comes out of and runs down the engine/bellhousing onto the ground. take the sender off, you will probably notice the piece it screws into (that screws into the block) is loose. unscrew it, throw some new teflon tape on the threads and screw it back in. you should be good to go.

That actually sounds like my problem... You can't see the pool of oil though can you? Where is it located? Back of the block on the passenger or driver side?

drivers side. your oil sending unit looks like a tin can with a wire plugged into it. follow the line of the head and intake back to the firewall and you will see it. buy another one.. they are cheap as hell and are known to fail. it may be whats leaking.
