My '91 Si has a leak and my buddy and I are going to be removing the oil pan and replacing the gasket tomorrow afternoon.

From what we can see (we have the full handbook), we need to remove a portion of the exhaust in the process. Does anyone know what part number the gaskets I need are to replace that section of pipe we pull out?

Also, any other tips or tricks for the oil pan gasket replacement?

 

the exhaust manifold has to come out because its directly under the pan.

you probably dont need a new exhaust gasket. its reusable.

but exhaust bolts and nuts are known to be rusty and break off. use PB blaster generously. i wouldnt be surprised if some are too far gone and cant help break and have to replace.

the torque on the oil pan is REALLY light, do not over torque. its close to finger tight, follow the torque sequence and pattern. thats pretty much it.

 

Cool, thanks! That's helpful!

 

Clean the bolt holes and mating surfaces really well with brake cleaner and use a in/lb torque wrench, follow OEM specs, for best leak-free results.

 

I haven't worked on a ton of EF's, but the two D-series motors I've owned always leaked from the oilpan until I installed myHondaHabit stud kits. When I bought my current hatch, the oilpan was a disaster area for sure. It was missing a stud and several bolts, there were 12's where there should be 10's... It was horrible. And it sucks to tap threads with oil raining down on you. I did have to tap one or two, but by replacing all the bolts with studs, it drastically reduced my time under there. If anything looks fishy at all, I would wait for those studs to arrive before disturbing things.
