1987 Water Leak
Hi all,
New 87 owner here. I have owned the car for 3 days now and after 90 miles on the highway and several trips around town I have developed a water leak.
It happened after a semi-hard run during my lunch break at work. It is leaking from an area on the top and front of the engine (see image)
Any idea what it is?
Thanks!!

Take a close look at the thermostat housing and the upper radiator hose & clamps.
By the looks of your driver's side valve cover, your new Corvette has been badly over heated somewhere along the way.

Cleaning up the area revealed the source of the leak. Its the intake manifold isn't it? Here is a video.

Thanks for the verification! I just called my local service department and the factory recall is no longer valid unfortunately. Looks like I'll be taking care of it myself.
I found a good writeup from a forum member who upgraded his intake. I am not trying to circumvent my further searching, but does anyone have any helpful links handy to a list of parts necessary?
Thanks!!!

When you install new intake gaskets you have to lay a good bead of sealant along the front and back walls of the block. You also have to overlap the intake gaskets by about 1" both on top and bottom sides in this area. Do not use the supplied cork strips that come with some intake gaskets. They are garbage and unrealiable. All surfaces must be immaculate and completely dry in preperation.
Your bead should look like this.
Remember there should be sealant overlaping onto the gaskets on the underside as well as the top side as pictured here on both ends of the engine block. So the bead is layed down first overlapping onto the head by about 1". Then you set the intake gaskets down while tacky. Then you add more sealant only on the uncovered upper edges of the gaskets to complete the overlap.
The intake needs to be set exactly straight down and torqued while the sealant is still tacky. If not start over. If you set then shift the intake around to align it you'll smear around the sealant and disturb the gaskets which compromises your seal.
