| Post subject: | 112,xxx miles and loud knocking noise |
I bought an 02 libby from my used car department a few days a go because I knew the truck was headed to the action anyways. I tried changing the oil and seafoaming the truck but the knock is still evident. At one time the knock almost went away entirely. At first it sounded like a rod but I am thinking it may be a lifter. In addition, I have access to a junkyard engine w/ 30k. miles on it for $1300. Should I just change the engine or try to salvage the one I already have? |

How loud of the knock? Mine has one on start up but it usually goes away after the engine warms up. It can be kinda loud in the winter.. |

Wrist pins can go and cause the piston to slap the cylinder walls. I bet if you took the valve covers off you would find some serious "sludge". Vavle springs are also suspect...they crack. |

the knock is loud and only went away once. As soon as the ac turned on the knock resumed and has not gone away since. Is it a better idea to just purchase the used engine than repair the one I have? |

have you had the A/C off since then? The pulley on the A/C compressor seems to rattle pretty loudly on mine but, it goes away when the A/C is off. |

I would say if you can't find the problem up top...vavle/lifters/ac compressor...put in the 30k engine. Save the other engine for a stroker kit...lol |

I got suckered into purchasing the engine today (They said they had someone else interested it as well) 1300isn't too bad for a complete drop in assembly. I will have it installed in the next two/three days by one of my mechanics. After all the work I did in my chevy I am burned out on working on vehicles on my only days off. |
