Have an '04 with no real mods - pullied, exhaust, that's it, 60K miles.
I had it dyno tuned in Houston because I thought I heard detonation but the tuners said there was none, though the tuning didn't get rid of the noise that I thought was the detonation.
Anyway, I blew a coil under modest acceleration a week or so ago. Had the coil and plug replaced and two days later the coil went again.
The shop doesn't want to mess with it anymore. They say there's an underlying internal problem - that the #5 piston is slapping the head and tearing up the plug. They figure a rebuild is in the cards.
As an option I've been looking at buying a rebuilt motor from someone like Promar (stock motor for $3K, some goodies for $4K) and dropping it in after the core exchange.
My problem is I don't want to spend a bunch of money to have my motor torn down for diagnosis only to find I'm going to discover a problem that would require an expensive rebuild when I could just buy a rebuilt warrantied motor.
What would you do? Where would you look for aftermarket motors?
The truck runs and drives but is missing bad on #5. What would be a rough ballpark estimate on a rebuild? I'm in Houston a lot and know PSI does good work.
Thanks,
Austin
