dropped valve seat
dropped valve seat thought everyone would like to hear this.after reading about Todds dropped valve seat,i took my pp stg 2 5.7 heads in to a local machinist to have a look at them before i put them on,just to give me some piece of mind.as he was looking them over,(the heads were fine)he said that his brother had dropped a valve seat in the motor on his truck.i asked him what kind and year,and he said a late 90's chevy.he said the heads were identical to mine but they were cast iron.(6.0l LQ4 i'm assuming)this was a BONE STOCK motor,and was not abused to his knowledge.i wanted to find out more,but he had to take care of another customer.i don't want to start another head bashing thread,just thought this might be of interest to everyone regardless what type of heads you might have,or even stock ones for that matter.

yeah it's cool, your not tellin me anything new I was kinda dissapointed too, but know there's a lot of room for improvement, it's like the car hits a wall up top, too much fuel and then the tranny not going into 3rd just bouncing off the revlimiter. lol see now I'm making up excuses, anyway not to get off topic. This may be good news for some PP head owners in a way. Just to show them that it more than likely wasn't their fault, just a factory defect.

Seats coming out is not all that uncommon. Any person who deals with heads on a regular basis should be able to tell you a couple of stories about it. Sometimes it just happens to the wrong people at the wrong time.

...from a legal perspective, it really does not matter if the dropped valve resulted from a factory defect or a defect casued by the vendor who ported and polished the aftermarket heads. Since the buyer paid the vendor consideration for the heads it is assumed they should have been free of material defects and, therefore, the vendor is on the hook for all damages to the short block, labor, replacement heads, rent-a-car costs, reimbursement of legal fees etc....
This concept is the same that would apply to GM if it purchased defective brakes from a non-GM vendor and sold new cars to others for valid consideration which assumes the cars and their brakes are free of material defects. GM is on the hook and the fact that its vendor goofed is not a defense...

I guess personally I'm just trying to point out just as 66Deuce did that the dropped valve seat we all heard about from a PP 5.7L head was more than likely just a factory defect. Just so people don't think that the quality of their product sucks because of a dropped seat that hadn't been touched.
