Default Changed to Morosso oil pan w Fel-Pro gasket. Pan now leaking?!

Hey everyone.

I recently switched the stock oil pan on my JDM GSR motor (swapped into a '93 del Sol with an S80 ITR trans) to a Morosso baffled oil pan with Fel-Pro oil pan gasket. My usual selection of mechanics that perform aftermarket parts replacements for me were unavailable in the short amount of time that I needed the swap done (track day August 6). I took it to a local mechanic that has done work on my family vehicles since he was available this past Friday August 3.

Now it's the night before the track day and I see that the oil pan is leaking from around the gasket. When I noticed it this evening I wiped the pan clean and left it with a piece of cardboard under. After several hours I see a 3"x3" puddle under the pan. I plan on taking it to the tech this week to have the issue resolved but my track day tomorrow looks to be a possible no-go....

Has anyone experienced a leaky Morosso oil pan or Fel-Pro gasket?

Thanks.

Yes, Moroso pans are known to leak. Some have had luck with different gaskets/retorqueing but only fix for me personally was a MyHondaHabit gasket and stud kit. Not cheap.

Update: I dropped the car off at the shop on the Monday that I was supposed to go to the track. Left a note for the shop owner with details. Got a call the next day. Turns out that it wasn't the oil pan gasket but rather the oil pressure sensor was leaking. Coincidence? Bad luck? The shop owner acknowledged how frustrated I must have been. He's a good guy and an honest owner. Perhaps it was just bad luck... Anyway, he replaced the oil pressure sensor and as of today (one week later) still no leak.

That is awesome! I have been in a very similar situation before. Occams Razor stipulates that the simplest and easiest explanation is usually the correct one. I have found this to be true but there are definitely exceptions. It looks like your's is an example of that. I'm glad to hear you were able to get it resolved pretty easily. Better there than after a tow!

I use the myhondahabit oil pan gasket too. I agree... not cheap, but definitely better than doing my oil pan gasket once a year! Mine is still going strong after several years! I am not sure it is the case for all but mine is a 2.1L B18C and the additional vibration means that I need to retorque the oil pan nuts periodically because they loosen over time.
