Ok so driving down the highway and there was a "pop" of sorts and the burban now runs like sh%^t and flashes the check engine light and sounds like it blew a valve spring....but it starts right back up flawlessly other than a loud noise and a moderate miss....the oil pressure is good...............valve spring???? timing chain?????? motor has 218000 on it...any ideas????? the FASTER the BETTER

thanks
Chris

P.s. any one in the Des Moines area that is willing to "lend" a hand??????/

 

Yeah I think valve spring.

 

Well after some investigating i found that the motor is toast....so im getting a used one put in for $1200......deal?????

 

Man thats sounds real good! Hopefully the used motor will give you another 200k+ miles.
