I finally got my motor fired up last night , but things just didnt sound right ??? , I figured it had some little problems from sitting so long and it was late so I would fix it today. Today I went out to play with it and saw this :o ( rockers hitting the valve covers )!! WTF these are the same valve covers I had on the motor last year , and I didnt change anything in the motor !!! All the rockers are still tight, nothing loose , cant see anything wrong ???. I know it wasnt like this before, you can see the valve cover move and hear the noise when it cranks over ??? ???.
Also this is only on the right side of the motor. No I just looked closser ,its on both sides , but the left side is not as bad, it's the intake rockers only.
Anybody have any idea WTF is going on here ???

I wonder if you doubled the gaskets if that would solve your problem? I don't know if that's a solution or not that would be accepted by the real mechanics on here or not. Just my 2 cents.

I have a new set of Ford racing tall valve covers, but havent cut out the breathers yet . So I just put the old ones back on for some test & tune. I just dont understand why thay hit now and didnt before ??

GREMLINS >:D !!! is all I can figure! Maybe it's time to cut in the breathers and go with the taller covers. ???

Your gaskets probably shrank, and you were bairly touching before (or now you are listening...)
Just double up the gaskets if youwant to to do the cheap route.

Before you do that though, lay a straight edge across the rockers to make double sure the studs aren't pulling out.

Thanks speedymopars , I didnt even think about the studs (thay are screw in ::) ), I'll check that next ! But you guys also might be right about the gaskets, I think the ones I used in the past were realy thick. :-\

Huh???? ??? ??? ??? ???

Some sets of rockers have two that are beveled to allow for that clearence. Check to see id you have two that are different and swap them to the correct locations.

NOW I'M COMPLETLY CONFUSED !!!!!!! I went out tonight to check things again / reset the valves / and put the tall valvecovers on it. Simple stuff right? NOOOOOO !!!! I set the motor on TDC #1 and the rocker was not tight ( it's a hydraulic cam ) so I lossened the lock, set the rocker to contact and as i tried to add some preload to it I could see the valve spring start to compress, WTF, now it thinks it has solid lifters ! I'm going to pull the intake off and check the lifters and I swear if I find solid lifters in my motor I'm going to visit the motor builder and STAND ON HIS NECK until he explanes how thay got there !!! I took him a Isky hydraulic cam and lifter set for this motor last time it was apart !! I can also see by the marks on the push-rods from the guide plates that the push-rods are sitting higher than the they did before.
-
Well I still dont understand what it's problem was, just sat to long I guess ???. But every thing is ok now. I removed each lifter one at a time and pulled them apart/cleaned them and put them back in, set the valves , and no problems :). So I put the new (to me) T ram on it and it fired right up today and sounds great !!! I just hope this nice weather lasts a little longer so I can take to the lake and send that Cheby powered jetaholic back to the trailer with his tail between his legs !! :o ;) ;D

Only if your new valve covers can stand up to your valve train beatin' the shit out of 'em. Judging by the oval logo on them I'm betting that's a no.

Stiffening up the valve springs...figured I'd do you a favor and put more of a load on the valve train to give you a head start...cause you're gonna need it.
Speaking of smog...yours should have some nice EGR goin' on with your boat being behind my pipes and all
