Valve guide failure

[JimmyP70]

Can a worn/ dropped valve guide cause a "skip" in an engine?

Juts had heads installed, mechanic is claiming engine is "skipping".

They're supposedly running a few tests recommended by the GM tech line, but they say they are are all but sure it's a valve guide failure.

Is this B/S or could it be true? I would imagine a dropped valve guide would be making quite a bit of noise (and damage) sitting on the bottom of the valve.

I'm $2500.00 into repairs for this car- a 2001 Monte LS w/ 3400 and 55,000 miles. Getting ready to scrap it.

What were the repairs that were performed?

Is it possible that the machanic may have scewed up putting the pushrods back in the engine? On this engine (and all genII or GenIII engines) have diffrent leangth pushrods, if they were swaped you would most deffinatly have a bent valve somewere that would cause the engine to "skip" really bad. Have him do a commpresion test to identify witch cylnder is cause the problem.

Do the rockers have torque specs on this motor? (i'm not sure, havent got into it yet) Or do they have to have the lash adjusted? Cuz if they need to be adjusted and havent (or are adjusted wrong) that would make a pretty good skip or miss, if it even ran at all.'

But if you scrap the car, how much you gonna scrap it for?

Checking on torque specs.

Push rods were not swapped.

14 lb ft on the rocker arms. No lash adjustment.

Thanks,

Broken Valve Guide

This would still cause a commpression issue would it not?

Picked up the car this afternoon.

Car was running like shit.

Germ from DPP had me look for bad connections.

Sure enough, the "skip" was caused by a connector hanging freely that goes to the coil pack.

Car runs great now.

If ever in RI, do not bring your vehicle to WAYNE'S SERVICE PLUS, in Providence.

It's "Service Plus an ass-rape".

This guy was ready to charge me another $1000 to rip off the head and repair the fictional valve guide problem. Moron.

Thank you guys for your input on this.
