Get yourself a vacuum guage to verify you have bad valves. On the guage, the reading should be steady, if it is irratic, then your have one or a couple bad valves. The guage can be aquired from any auto parts stores for around $30. Very good investment.

Oh, to answer your question directly ... poor driveability and loss of power.

Will the car act the same even if it had mis adjusted vavles as it would if the veavles where shot?

 

Do you have hydraulic lifters? If so then no. Unless you tighten the rockers really tight, instead of setting the correct lash. Valves are not adjustable, lifters/lash are.

 

The motor is a 85 and older gm replacment.

 

btt

 

Is lash what they talk about when they say they needed to adjust there vavles then?
