PRODUCT DETAILS
Honda Oil Return Pipe Gasket 15544 RWC A01 is an OEM Honda oil gasket that seals the turbo oil return gasket joint where the return pipe bolts to the turbo on a bunch of Honda and Acura turbocharged engine gasket setups. The turbo gets pressurized oil for lube and cooling, then it drains back to the engine by gravity through the return pipe. When the flange seeps, you’ll usually spot an oily haze around the turbo, heat shields, or the undertray, and it loves to collect dust so it looks worse over time.
Here’s the honest part, this little formed gasket matters. Any time you do a Honda turbo gasket replacement, pull the turbo, or even just loosen the return pipe, the old gasket normally comes out crushed, heat cycled, or it tears when it sticks to the flange. Reusing it feels fine until you spend the next few weeks wiping down oil and playing the fun game called “is it the return, the feed, or the valve cover”. We use these exact parts when we’re in there because a fresh Honda 15544-RWC-A01 gasket costs less than your time chasing a slow leak.
This is a direct replacement. It won’t change oil flow, spool, or how your car drives. You’re just restoring the factory sealing surface, assuming you clean the mating faces, keep them flat, and torque it to the factory spec.

Installation considerations
- Replace it any time you separate the return pipe joint, like turbo removal, return pipe removal, or related engine work
- Surface prep beats internet torque advice every time. Clean both sides, make sure nothing’s warped, then follow the factory torque specs
- This turbocharged engine gasket seals the return flange only. It won’t fix a cracked return pipe, a bent flange, or leaks from nearby turbo oil feed or coolant fittings
