S2K Sideways

I just did a valve adjustment ...we did it to specs and everything seemed ok.
I took the car for a ride on the highway and drove it hard for a little while...once i got off the highway and got to a light i started to hear a noise when i rev the engine to take off. It sounds like a buzzing that is similar to the Timing chain tensioner sound. The higher the rpms the louder the noise. It doesnt make the noise when the car is cold , only after you drive it for a little while. Could it be the TCT? this noise was never present before the valve adjustment.

might be tighten to much did they use a torque wrenh?

i know they used a feeler gauge ..im not sure if they torqued them with the torque wrench

Was the car completely cold? Usually it needs to sit overnight before adjustment. I don't think over tightening the locknut would cause tapping, but the tappet being to close would. It has to be cold because the gap is there to account for the expansion of the metal once everything heats up.

This was my first thought. Also your TCT sounds like a card in a bicycle spoke, it's a pretty obvious sound when you hear it.

i think they left the car the cool off for like a few hours...maybe it needed to be even colder? also i hear that they might have measured the wrong spaces ..so basically the valves may be way too loose

if they are too loose or too tight.. u might get a cel for a rich or lean mixture . well this is what i seen on k20 motors..

Check to see if your oil cap is still in place. If it is not tight it will work loose and fall between the engine/tranny and firewall and make a buzzing sound.

They may also have accidently left a tool in the engine bay that is now rattling.

Well, your confidence level in the work seems to have deteriorated a long way from the first post -- so did you simply take the valve cover off and let a cage full of monkeys loose on the engine? There's no point adjusting the valves unless you do everything right.

A few hours of cool off is enough. The exhaust valves and the intake valves have different specs....could the mechanics have mistaken which valves were exhaust and which was intake?
