Discovered the real coolant leak I have........my heater core YAY!

So I'm going to order a new core, heater control valve and all new hose(in bulk).

Since I have to drain some coolant off to do the intake manifold gaskets the timing is perfect. I guess better to have it happen now then in the moddle of the winter.

Lifted the back 2" more and turned the keys up just a bit so she'll sit level, and no the keys aren't turned up all the way, wink wink...LOL. I also changed the rear diff fluid with Valvoline 75w90 and replaced the greasy diff cover for a new chrome one :)

I pulled everything apart to do the heater core ....... come to find out the heater core is fine.

Replaced the HVAC blower motor since I was in there.....wow, what a difference. The new VDO blower I got from AutoZone has twin ball bearing

Tomorrow is D-Day, time to do the intake manifold gaskets, Taylor VMAX intake spacer kit, valve cover gaskets, new spider and Summit Racing Distributor. Also going to do the heater control valve and new hoses.
