Default Cam install blues

Installed the andrews 27 cam with the quikee S&S push rods. Adjusted the push rods 20 flats. Made sure it was on the flat of the cam not the lift when adjusting. As per andrews, if the original cam is red dotted its a direct fit. Mine was red dotted so I didnt pull the gear of the original cam. Installed S&S lifters. Used assembly lube on everything. Replaced the oil seal for the cam. Replaced cam bearing. New gaskets for the lifter housings and the nose cone. Made sure the lifter housing gaskets were lined up with the ports for oil flow. I have tapping like its lifter clatter. Oil is aerated in tank. Changed oil filter before start up. I also installed a new cam chest breather with the proper spacer. All gears were alighned with their timing marks.

Any ideas? What did I screw up? It went together pretty easy. I also cleaned and rebuilt the cv40.

sorry man, someone smarter will come along than me. As for the noise?
A couple of quick questions: did you soak the lifters? and the pushrods?
Upon start up, how long did you let it run with the clatter?
How many times did you start it?

IF the lifters were not soaked, and IF the oil pump was not primed, it takes some time for everything to get oiled.
AND even if you THINK you did it right, correct, start completely over with all of the adjustments. JUST to be sure.

I know. My first time was NOT correct... after I reset and adjusted everything, started up and no clicking.

As for the oil aeration....don't know.

After my build I had the plugs out still and turned the engine over for a few minutes to help get everything primed. Also as stated before you should definitely soak the lifters. I got a little chatter initially, but it cleared in 5 seconds or so. I wish you the best.

So let it idle for awhile to see if it clears up?

Im guessing that the airation is the lifters and push rods loading with oil and forceing the air out and back to the tank. Yes?

Is 20 flats enough?

Lifters make noise, but it shouldn't go on for minutes.

I could be wrong but I thought s&s quickies was 24 flats. Don't know that 4 flats would make that much difference but maybe.

Theres a couple of places that state 20 flats. JP says 20 flats but S&S states 4 turns or 24 flats. Then there was concerns about to much at 24. The rear cylinder is quite now but the front still taps. Im going to adjust the fronts to 24 flats and see if that changes. If it does then Ill also do the rear. Why would the rear clear up but not the front cylinder? Is there a difference between front and back? Also the oil cleared up, hardly any aeration in the tank.

Just took it apart to look at what I might have missed. Before I did I adjusted all push rods to 24 flats even though the back sounded good. Now the back is making the noise. Front no change. Everything I checked looks good timing marks right there. The only thing I keep questioning is the cam box breather. When the timing marks are lined up, the breather screen is 2/3rds into the houseing. how much does the breather effect oil flow to the lifters? I also am soaking the lifters to make sure they are loaded up with oil. Do I need to install a high pressure oil pump to do this cam set-up?

Going to start all over again tomorrow. Thanks again for all the help
