    A few weeks ago I had the rare opportunity to get out for a drive. I tagged along with Willywongka and a friend for a leisurely, due to traffic, jaunt up Skyline Blvd on a beautiful fall day. After a great pit stop and chat at Alice’s Restaurant, I decided to take the fast way home on the freeway.



    Unfortunately for me, before the drive I forgot to adjust my suspension from the a bit too low ride height it was at, <4" at pinch weld. Any undulations in the road at moderate speeds caused showers of sparks according to the poor E46 behind us on Skyline. I thought it was from my exhaust which shows many scars from over the years. Freeway speeds plus a good sized dip almost caused a catastrophe. Almost immediately after the horrible sound of metal bashing asphalt, smoke started to fill the cockpit. I pulled over, grabbed my fire extinguisher and looked under the car, only to find nothing. Soon the smoke cleared. I was almost certain it was oil, but my oil pressure was holding steady as well. Many years ago, shortly after finishing the engine swap, the oil pan was dented after hitting a large pot hole during some “testing” along some dark, industrial roads. I feared the pan had taken another hit, but maybe I was wrong. I hopped in and started back home, quickly accelerating to get up to freeway speed. Again smoke filled the air, but as soon as I backed out of it, it started to clear up again. As long as I maintained a steady throttle everything seemed fine, so I carried on and limped home 12 miles at 65mph. I pulled into my driveway and shut it off, going into the garage to get my Quickjacks into position to inspect the damage. I came back out to find a slick of oil starting to creep down the driveway, maybe ½ quart at that point plus who knows how much lost during the drive.



    Fortunately it’s a 7 quart pan so I quickly pulled in, but being so low, it took a little longer than usual to get the car up and another quart or so made it onto the garage floor.



    After the long clean up process, I was able to see how much it was going to cost me. It didn’t look horrible so I got onto dropping the pan with hopes of repairing it.



    But why didn’t I see any oil when I stopped on the side of the freeway, or lose oil pressure? I’m surmising that the trap door baffles in the pan were keeping the oil away from the crack while the engine was on and it was still circulating. Unless the pressure got high enough like during acceleration where it was forced out and onto the exhaust. Once I turned off the engine in the driveway the pan started to fill up and run past the baffles and out the crack. Unfortunately those baffles also made it impossible to fully clean the area around the crack on the inside of the pan which would make welding difficult. I didn’t have much to lose so I hit it with the TIG and while the bead is probably pretty porous due to the contamination, it’s seeming to hold up so far.

    Yikes! Lucky in terms of timing at least! Can you implement some sort of skid plate?

    Though it was great to catch up with you Andrew, I can't help but feel a little responsible for this happening =(. I hope you can get it all patched up so we can go driving again!

    Indeed Harry! After reinstalling it, I figured this was a good time to finally make the skid plate I considered after the first time I dented the oil pan. The entire issue is that the V8 pan hangs about 1.5 inches below the subframe. Combined with the fact that the tubular subframe doesn’t leave much area for attachment points for a skid plate left me debating (and procrastinating) the best design. I just decided to go for the simpliest and strongest, which resulted in a large, almost 24in wide, plate so I could tie directly to the subframe and make it as strong as possible. I used Ό” aluminum plate, and left a 1/8” gap to the pan, resulting in a loss of 3/8” more ground clearance. Not ideal, nor pretty, but hopefully gets the job done. I'll probably revisit the design someday.



    Willis, I knew I needed to raise the car a bit after the last drive, I just put it off and then forgot about it Ready to go again!

    Car is looking good. Bummer about the oil pan damage, but glad it’s been sorted. Hope to go driving with you all soon.

    Do you need a gap at all for the skid plate? (the old Jeep oil pans had skid plates welded to the bottom of them) After all you would gain back 1/8th. The plate would still be hitting and not the pan. The other thing would be to modify the pan itself. Probably buy another pan to work with until you get it right and then install that pan? That way you could not only gain back what you have now lost, but shorten the pan up enough to not hit? Just an idea. May be a poor one I don't know. Best of Luck!!!
