Need some opinions. Just rebuilt my motor and it has less then 200 miles on it. Has brand new 4 thread heads that I bought from an svtp member. The heads had been sitting for awhile, for how long I'm not sure. I believe he purchased them from modmax racing. Brand new stock cams and valve train. Car also has Mellings standard oil pump.

Ever since the rebuild Ive noticed a ticking sound on the passenger side head near cylinder 3 and 4. I figured since the heads had been sitting around for awhile it might be a bad lash adjuster.

My question is when I first start the car there is a rattle in the valve train for less then a second. Loud enough that you can hear it from inside the car. Its the only time I hear the rattle and other then the tick that I explained the valve train is pretty quiet.

Any ideas? Could that be from a faulty lash adjuster.

That would be my first assumption.

If it goes away that fast I wouldn't sweat it.
