2002 TJ 4.0L
I've noticed for quite awhile now that the side of the engine block exactly where the head connects to the block is slightly wet. I noticed this about a year ago. So what I did was sprayed the side of the block where it was wet with brake cleaner cleaning it up, seeing if it would come back. And usually after a week of driving or so or doing some hwy driving, I will notice it looks wet again.
Like I said, it's looked like this for over a year now, and everytime I clean it off, it comes back. I don't have any overheating issues and I keep up on all fluid changes. The only time the engine temp slightly spikes over normal is on the hwy going 70 mph but that's probably because of the big tires/bumper/winch/ect.
Any of you think I may have a reason for concern?
