Did I Mess Something Up?

[RoGuE]

When I changed my oil I forgot to put the oil cap back on in the engine bay and I had the truck running for about 6 minutes or so. To make a long story short there was black water pouring out of the muffler from a welded seam in it. As soon as I noticed the cap was off and put it back on it stopped. Did I ruin anything or is it all fixed now?

You didn't mess anything up with the oil (I've driven around without a cap before), but I'd definately check out the weeping muffler.

 

 

Your bearings might be bad.

OH SNAP

 

The dreaded muffler bearing.

Do you buy muffler bearings at the same place you buy headlight fluid?

Yeah, the same place you buy PCM lube.

I did my muffler bearings and flushed my blinker fluid at the same time.

black water coming from your muffler is normal. There is a drain on it to prevent rusting. Water is a by-product of combustion

Coincidence.
