Thread: hydraulic lifters always seem solid ???

Tweet

the ? is though why does the motor run good for 300 miles. if the motor run good for 300 miles why would the lifters tighten up then, if anything mine always get loose , but madmax changing the oil is not going to help eather. when the motor starts to loose power can you back off of the lifter adj. and make the cylinder hit then?
i just thought about this, but a few yrs ago i had a valve job done on a head i had and the guy knurled the valve guides to tight and after the motor got hot the valves would stick open, not wide open but just enough so it wouldnt build up any comp. and the motor would loose all power, but by the time we got it back in the shop it would have cooled down and the valve would be shut when we checked them. after about a week we found out what the problem was, but im happy to say they never found out who killed the guy that did the valve job.
