first off 1983 gl wagon. 1.8 4wd.

(recent investment, 650$ with 74k original!)

 

i crawled underneath today found an acumulation of oil around the pan and filter/pump area. i cleaned the area real well and what i saw (only when running)is a flow of oil running down the gasket area of where the oil filter connects/ not the oil filter itself but the block that its attched too. (not quite sure on part names)

it also looks as if the said 'block' from above, is not original and i can't see a trace of a gasket in between.

 

is it possible that the oil is coming from behind the oil pump pulley?

 

if not my money is on the probably non existent gasket thats supposed to be between the 'block' and motor

Subarus are supposed to leak oil, if it stops, fill it up!

There is no gasket between the oil pump and the engine block, only a rubber ring. It would probably be best to just take the pump off, clean everything really well, and determine if you need a new pump or a new ring.

The 'block' you speak of is part of the oil pump. I will call it a "plate" to avoid confusion with the engine block. The oil pump has a "plate" between the main body of the pump and the engine block. If Your leak is in between the plate and engine block, You need to remove the oil pump and replace (or in this case just put one on) the gasket. If the leak is beween oil pump and the plate, You can remove the pump and then remove the plate from the back of the pump and you probably have a bad o-ring in there. There should NOT be a gasket between the plate and Oilpump body

 

 

You mentioned a pulley which your oil pump does not have, If you are leaking oil from around your crankshaft pulley, that is a different story.

Follow my advice instead. The rubber ring uberscoober speaks of is the O-ring I spoke of. There ABSOLUTELY SHOULD BE A GASKET behind the plate, Which should be considered part of the pump.

Be warned that sometimes oil pumps don't want to come off. Maybe someone else can give advice on removing a stubborn fuel pump. I am not very good at it.

Hmm... Maybe we are talking about two different things? I was reffering to the part of the pump where it is flush against the engine block. I didn't use a gasket, I just put sealant on the mating surface and put them together. I didn't have to disassemble my pump so I have no idea what is going on internally.

 

 

 

 

Removing the pump is pretty simple. Once the bolts are out, use clockwise and counterclockwise twisting motions while pulling outward. Never pry sideways or crooked.

Okay, we are not talking about the same ring. I see what you are saying. Yes that ring needs checked if the leak is between the engine block and the plate.

 

In your second picture you can see how there is a plate about a quarter inch thick held to the pump with a single screw. What I am saying is if the leak is between the plate and main pump body, You have to seperate the two and there are 2 more o-rings in there.

 

And yes there should be a gasket where you are speaking of (between the engine and the pump. If you don't have one, you used sealant, and you would know better than I if it works just as well.

and you would know better than I if it works just as well.

 

Doesn't leak a drop.

my apoologizes for my un-familiarity with the sub engines.

 

that "blcok that i was refering to is the oil pump. and i think you guys hit the nail on the head. im almost positive whoever replaced the pump didnt replace the gasket, and im going to pick up the rubber o-ring, replace both and that should stop my outrageous leak.

 

thanks for the input, i dont know what i would do without this forum.

 

long live subaru!!

i once asked a gun smith, how to straighten a canted barrell on an ak. he replied. "its an AK, pound it with a hammer!"
