bad wrist pin, any fixs?

[jeepkid]

my mechanic told me i have a bad wrist pin at the number 5.. told me to put STP thickener in it and it should be ok for like 50k more miles, my dads jeep had the same problem and ran for 100k miles. was wondering if anyone knew a trick?

Get a second opinion...your sig. says "new 5.0"..??

Pull the plug wire off #5 &/or all the others (one at a time) If the noise goes away, or gets real weak, it's piston related (assuming its not a knock)

Alternators, fuel pumps, waterpumps, lifters, & fanbelts can also make "odd" noises.

its a knock. not many things in an engine can make that sort of noise, sig says new because it pretty much is.. its about 2 years old
