my 4.8 sounds like a diesel..

[jlam86]

Hey fellas,

My car is making a strange noise lately. It sounds exactly like a diesel from back in the day. louder tack tack tack sounds. Car runs smooth without any CEL or anything. You can't hear it from the inside of the cabin. Friend who is a mechanic said it is either the valves or the timing chain guide. Anyone else have a similar issue? diy?

also, i think my serpentine belt is chirping on cold starts. Once it warms up, it goes away.

lastly, my driver side valve cover gasket is starting to weep.

sigh...this car is getting to be quite troublesome. NOt digging it. she has 75000kms and is regularly serviced. anybody know of any good diy's for my last two issues? i've found info for the inline 6 but not the 8 cylinders.

Thanks in advance
