OT: Nissan oil problem, too much oil in crankcase? Options

[Trekkor]

Oil light came on today.
Wife took car took a shop to add some oil.

he added 4 qts. (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif)

We called Nissan...Car only takes 3.6 qts (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif)

Having 2 or so too many qts in the motor is how bad?

car is scheduled for an oil and filter change first thing in the morning, anyway.

Overfilling a modern engine can, and will, eat up the converter, the MAF, the O2 sensor, and various and sundry other bits. I wouldn't drive it around the block if it had more than .25 qt. over the mark. The Cap'n

Yikes, through what means does this happen? I ask because I recently fixed a leaking valve cover gasket on my bro in-law's 99 buick century (3.1 V6.. terrible engine to work on, avoid it like the plague). Because of the bad gasket, it had about 8 quarts of oil/coolant sludge in it, and he had been driving it for a few days. I changed the gasket and drained it and put in new oil and filter, and new plugs while I was in there. Should I have replaced more things? (it seems to run fine now, with no check engine light)
