    Best of luck Doug. Are your lifters hydraulic or solid?

    With a new cam the first 10 minutes of running the engine are the most critical. And if you have difficulty getting it running that is hard on the cam with the engine just cranking over.

    It's best to run the engine at about 1800 to 2000 RPM's for the first 5 to 10 minutes. The mistake that a lot of people do is to let the engine idle so the can hear the lope of the cam.

    After you check the rod fro straightness, but before you tear down the engine. I have been able to pull lifter up out of the hole with a long pick or piece of wire, to look at it. if you want to take it completely out you have to go through the oil fill hole or PCV if your manifold has those.

    Good luck

    Solid lifters.

    Yeah, I ran it at 2k RPM, but getting it started was tough. Lots changed during the rebuild and starting it was definitely different.

    Interestingly, I cut the filter open and it looks good. I have an inspection camera and will try to take a look later.

    I figured it out. Make sure you aren't drinking anything that you might spit out in laughter....

    I used an inspection camera and found that the #1 exhaust lifter had come out of it's bore when I removed the push rod and was laying on it's side. The push rod was going into the bore deeper since there was no lifter. I was able to use the magnet and get it back in the bore. Problem solved. I set the lash on #1-#4, but it was either right on or close in all cases.

    Well I'm always drinking, but I did not spit it out or laugh.

    It's is one of those things that sometimes happens. Glad it was nothing serious and all is well again.

    Doug,

    That is good news and now you can begin to have fun. I had one of my solid lifters start to crack for some reason years ago and had to replace it so I had the whole set replaced.

    How did you discover the crack?

    Doug,

    That adjustment just seemed to keep working loose and we would adjust it a little and a few days later it had gotten a little loose and the we marked the adjustment and it hadn't changed so we decided to pull the lifter and see if it was OK. What was happening was the crack was just slowly getting worse and that was letting the adjustment get off a little. Also a little extra noise at that lifter but it was hard to tell as my cam was kind of radical and they all made noise.

    Geez Doug, when you said the push rod was loose, you meant REALLY loose ! Glad you got it figured out and all is well now.
