Post Rocker Noise?

There's some noise coming from the passenger valve cover (6th or 8th cylinder?) Someone told me it might be a loose rocker arm.

How can I determine if that's what it is? And if it happens to be this, how can I fix it?

I know they are roller tip rockers, but I don't know the specs.

if you do it with the engine off you have to have the manual to tell you if the 0 degree mark is suppost to be at #1 or #6 for whatever valve intake or exhaust you adjust.-the crank spins twice for every time the cam does- when you get all the play out of it give it 360 degrees more (one full turn. this way is straight out of the manual just follow the directions and you can't go wrong, thats how we did mine and i never had to re-adjust them with the motor running. if you like oil squirting all over you, the engine bay and esp the hot headers(if you don't lay an old blanket over them) you can adjust them with the motor running. i find the loose one and tighten it till it stops tapping and give it 1/2 a full revolution more. they sell little doo-dads that snap on the rocker to keep the squirting down if you can find them. if it was tight before and became loose you should find a new nut or double nut the existing one so it doesn't back off again.
this aint really something you ought try for the first time by yourself i gotta tell you. but you should have no probs doing it by the book

Thanks for the reply.

If you think the job might be a bit tough for a rookie like me, I'll take your word for it! I get frustrated very easily. Something I'll have to get over!

Question

Is it a mechanical or hydraulic cam? I know you say the engine has been built up.

If it is mechanical, you need to set the lash cold and then again once warmed up. Hydraulic, you can do a static lash setup and then a running setup.

A trick is to put the timing light on the cylinder you are concerned with while running and the quick flashing will let you "see" if there are any defects, i.e. a broken valve spring, bad rocker, etc.

Do you have aluminum roller rockers or stamped roller tips?

In a word, I don't know!

I've never actually taken the valve covers off to look at the rockers. I was told they are roller tip rockers. Thats all I know about that.

They are hydraulic lifters, if thats what you meant about the cam. All I know about the cam is that it is "big."

Lots of unknowns here. But I haven't been disappointed with the amount of power this thing has. (or maybe its just because its such a light car)

Sounds like you just need to perform a lash adjustment. You can either do it cold, as has been suggested or while the engine is running.I would definitely find a set of those oil splash stoppers or utilize an an old rocker cover with the top center cut out to control the oil spray.

If the noise is still there after the adjustment, there is a mechanical defect.

Hey bullheimer:

I know I said I'm chicken to do this myself, but just suppose...

Is the danger that I would **** somethin' up? Or is it that I might get frustrated? (probably both!)

In any case, would you mind going through your directions one more time? so a layman like me can understand?

Thanks,
