Yesterday I bottomed out the sump while traversing a huge pot hole.

I didn't stop to look for damage.

I should have.

Today I took my wife for a nice cruise up into the mountains. We were almost home when smoke starting pouring out from under the car and the oil light came on.  I had nowhere to stop (drainage ditch on my side), so I drove for another couple of hundred meters until I could pull off.  When I looked under the car oil was draining out of the bottom of the sump.  The oil drain plug was missing.

I had the car flat bedded to my place and when I jacked her up I found (no surprise) that the drain plug was missing and that there was scuff marks around the sump plate.

It looks like the sump plate had taken a direct hit on the pothole and the oil drain plug had been damaged.  I'm guessing that through engine vibration the plug had worked loose and eventually fallen off.  Thank goodness it didn't happen when we were on the freeway (only minutes before).

Anyways, the car in up on jack stands and waiting for new oil.  I'm also going to install a 'bash plate' under the sump (better late than never).

Tomorrow I start her up.

I'm not sure if the engine is damaged. 

Fingers crossed.

Bummer---everyone who sees this will be rooting for you.

 

Chances are that you are golden.  I watched some vw engine blow ups today on you tube.  People actually drain all the oil then run the engine at full power until it blows.  I was very surprised that this took 3-4 minutes so from what you described you will be fine.

 

Sorry this happened to you--please post and let us know everything is fine!

I've knocked out a couple sumps myself.

The last one has ended up costing me a bunch.

I run a CB thin line wide glide sump as it only adds 2" to the engine. The first time I bottomed out it cost me my Mainely sump plate with drain plug. The contact turned it into a potato chip. The second hit loosened the sump a bit. At least, that's what I thought. 

I noticed that I was weeping a little oil between the case and the sump so I tightened it up when I changed the oil. A couple days later it started to weep again. A clanking sound developed at startup as well.

I let this go for several months until I started losing oil pressure suddenly and sporadically. I would check the oil level, wiring, senders, everything checked out. I finally pulled the sump plate and discovered the oil pickup tube had broken loose from it's mooring at the bottom of the case and was moving freely.

You have to open the case to fix the tube. We discovered that the tube had been bouncing against the camshaft (clanking sound)which had worn a hole into the tube, causing the drop in pressure. The sump mounting holes were disfigured as well.

So, new pickup tube, new camshaft, a "while we're in here" refresher and a new sump tank and we're good to go.

 

Best to check everything, Ron.

Try as I could I could not figure out how to attach a skid plate.  There isn't anything to attach the plate to, so I ended up not putting it on, even though I had already cut one out of aluminum.  Maybe this winter I can put the IM up on the hoist and figure something out.  I really do need something under the sump and merged header.

As for the engine......it lives!

 

I put in another 6.5 liters of Swepco, at $10 a liter!!, and fired her up. 

No smoke

No banging 

No knocking

No seized bearing

No rod through the block (okay, I'm getting carried away here)

 

I'm thanking my lucky stars on this one!

Heck, I've always been a fan of Peter Sellers, and the name Hrundi V. Bakshi has always stuck in my mind.  I've used it a couple of times in different situations, always to see if anyone recognizes it.

 

Glad to see, though, that your engine seems to be fine.

 

You got it, Stan.

I'm having a hell of a time keeping my sump plate nuts tight.  I carefully tighten them up and a few days later I find they're not longer really tight.

Since I have a center drain plug I won't have to take the plate off again, unless I have to take of the sump itself.  Should I try Loctite?

Ron,

As  I mentioned above, I had a similar problem after banging mine. It ended up that the impact had distorted the holes on both ends of the sump. The metal is thin and soft on these sumps.

Rather than purchasing a new one (with the same issues) Tony has replaced the damaged threads with sert fittings and built up the material around the holes. It's being surfaced now.
