Water in oil (And I know you're thinking gasket)
 

Here's it quick:

I have an 86 4runner that had clouded oil. I changed the oil because I can't believe it's the head gasket, this truck hasn't moved in a while. The oil is fine until I washed it before trying to take it to DEQ the next day. Then I find the oil to be clouded AGAIN on a quick look before leaving. Where should I start in trying to find the problem? It was fine until recently.

THANKS!

What engine?
White smoke out the exhaust?
Coolant level in radiator dropping?

A search on this site will turn up numerous threads that may help you out.

You refuse to believe its the headgasket? well... the only thing that could mix with oil is water/antifreeze and that would make it milky. so seems like you're SOL.

yeah, maybe its not the headgasket guys.... his block could be cracked.....:horse:

Or the head could be cracked...

or the timing chain cover is worn through.

Ding!

Being an 86, it's not a 3VZ, it's a 22R(E). Seeing how this is an extremely common problem on the 22R, this would be the best bet, especially if there aren't any problems with overheating or oil in the coolant.

Take off the valve cover, and take a look down the front of the motor. When they get old, sometimes the timing chain will wear through the guides, and start chewing through the side of the timing cover into a water passage. If you see scrape marks down the driver's side of the timing cover, this is the cause of coolant in the oil. Swapping the timing cover isn't a terribly difficult task to swap out. You can do it in an hour if you know what you're doing, two or three if you don't.

Assuming, of course, the engine has not been swapped. :)
