Oh boy,
The front and rear intake manifold seals had swelled (silicone) and the engine was leaking quite a bit of oil. I had planned to pull the car into the garage to put the new intake gaskets on. However, I was suspicious of a coolant leak. The previous owner had used stop leak at some point in time. I pressure tested the system at less than 20 lbs psi and noticed the pressure dropped quickly. I left the pressure tester on and started the engine to see if it was a head gasket. I discovered the leak as the engine warmed up. I had steam coming out of the heater/def vents. The car stalled and would not start for a while.
After I removed the pressure tester I tried to start the car and it would not run. I got it to run for a minute and then fire once more while trying to start it.
My guess is the leaking heater core has gotten the ecu damp. I left it sit thinking it might start the next day. I noticed the check engine light does not light up when I put the ignition to the on position (prior to trying to start). I removed the trim panel under the heater core and it had antifreeze all over it.
How difficult is it to remove the heater core?
Is my ecu toast?
