It is inconsequential. It looks like it is some protective coating. Aluminum doesn't scratch steel.
Thanks for suggestion Beno. I will use it .Use it.
It is a F'ing gasket; it is not the space shuttle.
My 16k mile old FelPro HG that blew last spring had no sealant there so I did not put it on the OEM HG I installed. Neither one leaked oil.Dammit, I forgot to put seal packing in front of the head. Still didn't torqued the head , shall I take the head of and put the FIPG there ?
O-ringWait, didn't we lose a space shuttle because of a gasket ? Or was it an O-ring ?
And how did they figure this out when there was no evidence to examine?O-ring
I turned 18 that day. I was actually kinda bummed and now I can appreciate my parents for that. I didn't even read your post bc it just another lie formulated by the government. However, today I don't feel sorry for the people onboard because they had the privilege of dieing for a cause greater than themselves. Buy guns!This Is part of what THEY said.
he Space Shuttle Challenger disaster occurred on January 28, 1986, when the NASA Space Shuttle orbiter Challenger (OV-099) (mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members, which included five NASA astronauts and two Payload Specialists. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida at 11:39 EST (16:39 UTC). Disintegration of the vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff. The O-ring failure caused a breach in the SRB joint it sealed, allowing pressurized burning gas from within the solid rocket motor to reach the outside and impinge upon the adjacent SRB aft field joint attachment hardware andexternal fuel tank. This led to the separation of the right-hand SRB's aft field joint attachment and the structural failure of the external tank. Aerodynamicforces broke up the orbiter.
The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor after a lengthy search and recovery operation. The exact timing of the death of the crew is unknown; several crew members are known to have survived the initial breakup of the spacecraft. The shuttle had no escape system, and the impact of the crew compartment with the ocean surface was too violent to be survivable.
