    I appreciate your time spent on this as well as everyone else's. I'm not going to lie about my break in procedure so get ready to yell at me. I let the car run at about 2000 rpms for about a half hour or more. I then ran it like that again for about 20 minutes before my brother, who helped me with the rebuild, said "Lets take it for a spin". Out on the nearby country road we went with open headers ablaze. We did dog it a little in the beginning until I got my brother to smile. He had been very depressed lately after his wife passed away several months ago and it was the first time I saw him smile and actually laugh a little. Whatever I may have damaged at the time in the ring breaking in department was worth it to me. After that I would take the car on about a 40 mile drive going at various speeds. I think that I have about 400-500 miles on the engine right now.. I live in the country and was going in town later today to get the rubber tipped air nozzle so if that is my next step I'll be testing around 5:30. I hope I can hear what I need to and narrow this down. The thought of having to take the head off and dealing with those headers again really urks me but I will do what I need to do. Step by step with you good folks helping me will hopefully help other in the future.

    ((I have about 400-500 miles on the engine right now)). Ok, the rings are not seated in yet, most likely... Usually, around 1000 miles that happens.
    I've heard guys use, good and bad, but, I don't think BON AMI would be the way to go. Just my opinion.
    How ever, I would do the ring seating in process with out delay...

    Does any one know what that shop has for bore/hone opts????


    Since some cyliders don't seem too bad, maybe some rings are on upside down and/or wrong groove??? Anywy-a couple dollars for some BonAmi is cheaper than new gaskets-------and it works-----but things need to be installed correctly---------

    I sure wish he would answer about the things I've requested------- I've dealt with FE engines since they came out in 1958 and have seen what does and doesn't work-----------

    Sorry had to run into town. Here is what I used. Comp Cams Valve train assembly spray, Sta-Lube Extreme pressure Anti-seize engine assembly lube and I used Castrol GTX 10W 30 motor oil. a Ford service tech/manager for many years told me to use that. It's been changed twice already.

    I thought Bon Ami was a type of cleanser like Comet. I'm listening to your idea.

    Bon Ami isn't abrasive----------the old adds used to towt "never a scratch"

    Any way-BA has over the years been used on varius lapping in opts-----you sprinkle it above the carb while you rev up the motor-rum, spr BA, rum, spr BA, Rum, Spr BA-----------do it over one primary port at a time, going back and forth as it will go into 4 cylinders according to your intake manifold design-alternating with sprinkle, rev, sprinkle rev sprinkle rev---------a few times and switch ventruies-
    This has been used over the years on many industrial engines, race engines, aircraft engines,etc to lap in rings that weren't seated properly---------and today it seems that more and more rebuild projects are resulting like yours probably from faulty hone process and/or oil used or too easy break in procedure-------

    Use up a whole can---------don't stop early------but do make sure that it goes into the carb as sort of a dusty cloud-no lumps or streams too big for the carb to mix with the inflow-----

    And see if you can get some Brad Penn or Joe Gibbs BREAKIN oil

    I still want to see pics of the rocker assy and oil splash shields from the top end

    Using this, is not the same as following your friend in front of you traveling down a dusty road at 60 mph, and you for got your air cleaner, kind of thing... Hahahaha.

    Hi: How much is a little? All it takes is a overlapping oil ring slinger. I am new to this forum so I don't know if this was already mentioned. You may have to tear it down to find out where the oil is coming from. This happened to me years ago. Just my 2 cents worth. Good-luck.

    Actually, it could be a few things. That's why I posted about the air nozzle testing in post #9. Helps isolate an area of fault. Leads you into the right area so you can fix it without just guessing. More of a pin point to the problem... May not have to tear it down...

    I am really not wanting to introduce cleaning products into this engine at this time. Especially after reading a lot of negative comments about doing so. I do appreciate the tip though as it might be fine to do. Old remedies like this can work wonders at times when other methods fail. I am having to modify a rubber tip to use to do a leak down test since the spark plug holes on these motors are so huge. It won't be til later this afternoon that I can see if anything can be found by doing this. I am so ready to get this behind me but love the challenge at the same time. I really don't want to break the motor down again so hoping there is another way to figure out and solve this problem.

    Also, I noticed in your photo, is one of those a replacement bolt. They should all be hard bolts. Here's what I mean. Looks like this one has no markings on the top. If so, it has only a no 2, standard hardness. Wrong bolt.

    Ok, good deal. Just one last thing on that bolt. I'm sure you do know, but it's bugging me to make sure.
    Please note this just as a review...
