600 miles on complete rebuild of my GSR. Warmed it up for about one minute then drove out of a parking lot onto the street. I proceeded to do a nine grand pull in first gear. When I pressed in the clutch to come to a stop the car went from nine grand to one grand and then died. However there was no pause in between RPM points. ( 9 to 1 then died.) Then I tryed to start the car again and it did not even sound like the car was turning over. The starter engaged but nothing else happened. We pulled the plugs and they were nothing but black and burnt (fouled). We then pulled the head to take a closer look and see what could have happened. There is no apparent damage to anything and the valve seals are not leaking. The cylinder walls look untouched no ring damage. I also noticed oil soaked on the exhaust manifold before pulling the head but nothing else outside of the motor. I am stumped as to why the motor would die, why there is quite a bit of carbon build up on top of my pistons, but yet nothing appeared to be broken, cracked, damaged in anyway other than the spark plugs being fouled. Thanks in advance for any advice.

 

Could the head gasket either be blown or improperly seated maybe?

 

No there was nothing vissually wrong with it upon removale. I also have arp head studs so it is prettly much imposible for it so not seat correctly.

 

is the block assy. rotating freely?

 

yes

 

When I put my hand on top of the pistons I can move everyone of them . Is that normal?

 

It mite have jumped time, even if the pistons are loose that wouldn't cause any motor starting problems. did you do a compression check before you broke the motor down and what were the readings?

 

ill put my money on a jumped timing belt or sumthin in the disrtibutor. definately sounds like a jumped timing belt, might as well have the head check for bent vlaves while it's off though, reset timing and sehll atart right up, if your distributor is ok

 

did it run after uu put new plugs in it?
