No pressure in the no. 3 cylinder. Has some white smoke out exhaust.

What is your question?

My car has a little white smoke coming out of the tailpipe. The coolant is not low and there is no signs of coolant in the oil. I just did an oil change and it still looks brand new with no discoloration. I did a compression check on the number 3 cylinder and it came back with basically no compression. I changed the plug and plug wires and it still is doing the same thing. It honestly drives ok but I can feel the misfire vibration in my shifter. What else could this be? I was thinking it could be a gasket but not sure if there is a more simple solution before I dive into what will end up being a basic rebuild. Thanks.

What makes this problem better or worse?

I see the smoke more when idle, do not notice misfire during drive.

How long has your 1996 Toyota 4Runner had this problem?

just noticed it.
