Removal: We arrived home on Saturday and after unloading everything, I
began pulling the motor from the Cobra. After getting the car up in the
air and removing the wheels, I had a little bit of good news when I
drained the oil and there was no water in it. That means the block and
heads hadn't been damage to the point of water jacket fracture. Always
a good sign. While the oil was draining, I remove the strut-tower brace and upper intake manifold. When I picked up the upper intake, there was a rattling sound coming from inside. I shook the intake around and the head of an exhaust valve dropped out of the port and onto the bench!   | ||
Here are some more pictures of the removal of the motor:        | ||
    | ||
| Motor Disassembly: Now with the motor on the stand, I could start the tear down and find out the extent of the damage. First to come off were the valve covers and exhaust headers. It was apparent right away that #2 cylinder would be suspect. | ||
  | ||
Do
exhaust headers normally contain oil? (BTW, the next day there was a
puddle of oil on the ground from oil leaking out of the H-pipe.
That's how much oil got pumped into the exhaust)   | ||
Lets
take a look in the exhaust ports: Nuber one has a valve, number three
has a valve, number 4 has a valve, number 2, No Valve!    | ||
Intake
mainfold comes off next. Now we can take a look into the intake ports.
Number two intake valve is gone. Also somthing appears to be wrong with
the intake valve on number 6. :(    | ||
With
the rockers off, I can remove the pushrods. #2 exhaust pushrod is the
bent one and it won't come out. It is 'mushroomed' at the bottom. Also,
with the rockers off, #2 exhaust spring has release all its pressure.
That means the valve stem is straight, unlike #2 intake valve.   | ||
First the drivers-side head comes off. The head and pistons all look O.K.  Next the passenger-side head is remove. Here we see all the damage. The head and #2 piston are toast.     | ||
| The
rest of the pictures are the remaining dissassembly of the motor and
putting it on the cradle for sending the short block back to Buddy to
be checked out. #2 cylinder will need to be re-bored if it can be cleaned up at all. If not, I'll need a new block. I spoke with AFR, they gave me a RMA for the heads. Hopefully they will cover their replacement. The problem with the #6 intake is that part of the #2 intake valve head has traveled through the intake manifold and down to the #6 intake port!             | ||
