oil pan leak

Hello, I have an 82 rx7 gsl. the motor is a 12a and it is manual transmission. My issue is that I have a major oil leak coming from what I thought was the oil pan gasket but i see it pouring out of a little tiny notch just off the oil pan by the tranny. it is where the tranny mounts to the engine the little notch is on the engine side. What is this little notch? could it still be the the oil pan gasket?? any advice would be great. Thank you.

pic??
TX has no connection to oil pan, so would presume its still the pan that is the source. Your sure its not an oil cooler line connection at the Block, dribbling to the pan….?

you can see the little hole by the bolts of the oil pan. the oil pours out of that little hole. I also took a pic of the starter and oil line going into the engine as well. these pics were taken with the car off. I will take pics while its running and oil pouring out for you. Thank you.

Clean that whole area up really good with same carb cleaner, degreaser, soap and water, whatever you have. Clean the rear banjo bolt area in the last pic also. Next, lay some papers under the entire area over night. This will help narrow it down. remember, the oil is "running downhill" so blocking the front wheels and jacking the car up so the rear is higher might also help narrow it down.

Based on what I see, I'm leading to maybe an oil cooler o-ring leak. Look at the rear iron under the oil pedestal. Does it have oil running down? Might need to start the car so oil is flowing. Reach your hand under the oil pedestal and feel for oil.

so I ran the car until it started coming out of the opening and i looked all around and the only other spot that had a very small drip was coming out of a small hole on the starter. this hole had a piece of rubber on it blocking the hole. anyways. it definitely is coming from that little hole between the engine and the tranny. Thanks.

the rear end is higher than the front. the car was back on the driveway facing the road. when I was taking pictures. I know it was hard to see but there was a oil following the seam of the oil pan to where that hole is. everywhere else is dry.all the oily black stuff was a spray done long time ago.

If this is the case, pull the starter and you should have a bunch of oil. There are only a few things that can cause oil to enter that area. Other then a cracked rear iron, the rear main seal and tension bolts and the suspects.

It's where the oil filter screws on to.

On the right side of this pic you can see where the oil pedestal bolts to the rear iron. There are two o-rings that go between the rear iron and oil pedestal. The o-rings can go bad. if this is your issue, there will be oil under the oil pedestal.

Ok, so I cleaned everything all up . ran the car till it leaked again. I see no oil anywhere from the pedestal to the pan. the starter was clear of oil as well. it seems to be seeping through seam of the oil pan to engine at the back of the pan. So I guess that means its the gasket?? If it was the rear main seal. where would it be leaking?? Thanks again.

Its not hard to re-seal the oil pan but its time very consuming without the proper tool such as a car ramp, floor jack and 1/4 10" socket/ratchet. Be sure to use a sandpaper and a nail punch to add a dent/scour on the oil pan flange to ensure that silicon stays when you tighten the 10mm bolts. Do search under my SN on how to modify the ROPR for hints.

Rear oil seal? You may as well replace the clutch also.

^May as well rebuild the engine lol

You can remove the rubber inspection plug on the bell housing and see if oil comes out to tell if its the rear main.

so i removed the gasket and gonna put new one in. but I again removed the starter and I borrowed a little bendy camera to look inside the housing and there is just caked on oil residue on the bottom under and around the fly wheel. i jammed a rag in there to wipe up and residue. there was almost nothing in there. so I dough the rear seal is bad judging by the amount pouring out while the car was running by the oil pan. So i can rule out the seal. correct?? I ll replace gasket and give another good cleaning and see where in at.

so there's bad news. i cleaned up the engine really good. and did the rtv gasket and let the car run for an hour after it dried all up.. looked under the car and oil is now coming out by the exhaust manifold between the rear iron and the rotor housing. holly crap.

Was it recently rebuilt? I bet they didnt put RTV or Hylomar on the legs... See if you get get a torque wrench up in there and make sure torque on the tension bolt on the bottom right is about 30 ft lbs. If you can only get a standard 17mm wrench up in there be careful not to over do it.
