I own a 98 Acura RL 3.5 and notice oil is leaking from around the oil pan. Is it necessary to remove the engine in order to remove the oil pan?

No you shouldn't have too, You just have to drain the oil out and there's a lot of little screws that hold the oil pan on take them all out, You might need to lever off the pan with a flat screw driver, Once done, get a gasket scraper and make sure to scrape all of the old gasket off.

Thanks for your response. But there are at least 4-6 bolts that I am unable to get to because they are located behind a frame. And too I located the following relative to my question. ...Here are the procedures. OIL PAN Removal 1. Disconnect negative battery cable. Disconnect positive battery cable. Loosen idler pulley center nut and adjusting bolt. Remove A/C compressor belt. Disconnect power steering switch connector. Remove adjusting bolt, lock nut and mounting bolt. Remove power steering belt and pump. Remove left and right side exhaust manifold covers. Raise and support vehicle. 2. Remove front wheels and splash shield. Remove damper forks. Disconnect suspension lower arm ball joints. Remove axle shafts and intermediate shaft. 3. Drain engine oil and differential oil. Install drain bolts using NEW washers. DO NOT over tighten drain bolts. Disconnect Vehicle Speed Sensor (VSS)/power steering speed sensor, but DO NOT disconnect fluid hoses. Remove lower plate from rear beam. Remove A/C compressor. 4. Attach chain hoist to engine. Remove left and right side engine mounts. Remove left and right front engine mount bolts. Place transmission in Park to lock secondary shaft. Remove 36-mm extension shaft sealing bolt. Disconnect extension shaft from differential using Extension Shaft Puller (07LAC-PW50101). Remove differential mounting bolts and 26-mm shim. Remove differential assembly. Remove engine stiffener. Remove drive plate cover. Remove oil pan and "O" rings, refer to diagram.

Wow! That's a far cry from what I'm use too..... Those engines must be tight packed in there. Sorry i couldn't be of help mate.

I own a 1997 3.5 RL, and i want to replace the oil pan and the oil pan gasket myself. What are some steps that i need to take to do so.
