Ok, so for those of you who have read some of my previous post are gonna realize I don’t get things done too fast. We just had out 1st kid and wife will only let me in garage every once in a while.
I rebuilt the 289 w/ all new parts except the block, crank and rods. I installed a new cam and lifters (summit generic of Edelbrock performer plus). I just recently got the engine timing set where I like it and the carb semi tuned. I have only ran this engine for about 2-3 hours and I have changed the oil once so far. I do not have tags / insurance on the car yet so no real driving, just 1 trip around the block and lots of running in the garage. I did a proper break in and followed the cam instructions.
I have noticed I have a lifter knock at idle that increases with RPM. I started investigating and pulled the valve covers. I thought it was coming from the left bank so I started w/ cylinder #1 and pulled the rockers / pushrods, ran it at idle no change, reinstalled. Then on to #2, pulled the rockers / pushrods, ran it at idle and knock when away. I reinstalled rockers / pushrods and knock came back and then repeated the process one more time till I was satisfied this was the cylinder.
So questions.......
I have no real time or miles on this engine, so do I run it 10,000 miles w/ regular 3K oil changes and see if it goes away or fix it now?
Will it cause any harm if I let it go a little while? I would like to focus my attention on the front suspension alignment and drive the car a little (also rebuilt front suspension when engine was out).
If I fix now do I change all the lifters or just the ones in question? I have an extra set from my engine rebuild kit. Camshaft came with a set and so did the engine kit. I used the lifers from the cam during rebuild.
Thoughts? Thanks and advance!
