302 just put back together
Hey guys I posted awhile back with some head problems (cylinder head not mine). I have since put the truck back together very carefully and yesterday fired it up. It fired immediatly, I had oil pressure so I was stoked. After a few minutes I still had some chattering and I tried to let it run out the kinks for a few more miutes and after no change decided to shut her down. So tommorow I was going to go back in and see whats what. The reason I am posting is to see if anyone has any ideas. I know there could be million things so I figure as of now its either a loose rocker-arm, a clogged pushrod, or a stuck lifter. I just had the heads rebuilt so I'm pretty sure they are fine. I didn't have anything that seemed to jump out to me as a possible problem so I figured I'd ask people who might know. Thanks

If you have good oil pressure and nothing is obviously wrong under the valve covers, I would not be afraid to drive it. I have had lifters take a long time to shut up. I believe the internal clearances in a hydraulic lifter, is about the tightest clearance in most engines. (a few ten thousandths if I remember correctly). The slightest amount of debris can make them hang up and tick. It usually works its way out if you are using quality lifters. I know it's discouraging to listen to a fresh motor that sounds worn out though.

I don't know what kind of rockers you have, but my Crane Energizer roller rockers got their 4th adjustment today, but this time I locked it in with threadlocker blue, and I turned the engine over at least 4 times to make sure the adjustment was correct. So as soon as I fired it up, it started ticking again. I drove it down the road, and it stopped. Sometimes, you just gotta drive it so that oil can get to the rockers, otherwise they like to make noise, and I'm sure that applies to any kind of rocker. If you are running something with poly-locks for stud-mounted rockers, keep in touch, I have a bag of tips and tricks that I've learned in my experience with them.

Hey guys just wanted to say thanks for the responses. I took the cover off the drivers side after a listen with the stethescope and found that one of the rockers had either worked loose or I forgot to tighten it in the first place. So I put it back together and its running pretty damn strong. I have a check engine light so I guess I'll pull the codes and see if I can fix this. So again thanks, these forums have saved me a lot of money and taught me a great deal.
