    new push rods help required

    Hi all, I have bought a new set of push rods for my Ford 429 engine from Sumit racing in the USA which a friend kindly carried back for me.
    When I unpacked them it is clear they are physically different so I thought I would check with the forum for peoples thoughts.
    The old rods have a ball which looks like it is welded to the end of the rod, the new rods just have a domed end. They both look like the same resulting diameter but would like some reassurance before fitting them !

    Can't answer your question directly as I have a different engine but to ask the obvious - Summit have a good reputation in the US, have you called them?

    I have emailed them but been searching internet this evening and have found several sites offering 'formed end' rods which are this shape so I am pretty sure they are ok to use.

    Looks like I am going form one problem to another. Fitted new rods and ran the engine just fine, went out for a short test drive and all good. Changed the oil and filter yesterday as I didnt want to run the engine with all the debris from the worn rods and span up the engine for a good while and all good.
    Took her out for a test drive today and after a few miles I got a squeak which sounded like the fan belt so immediately went home and put spray on it with no effect.
    Took the fan belt off completely and squeak is still there and tracks with revs. Now very depressed and struggling to think what has happened now.

    Paul,

    Fingers crossed its just coincidental and your thinking the worse. Use the stethoscope method of pinpointing down noises which are difficult to locate.
    You can use a large screw driver and put it to against your ear. Be careful of moving parts. See video link.

    I have taken a video and posted it on youtube

    Also found a post on a Rover V8 forum with a similar noise on an engine rebuild and they are saying it can be the cam shaft and you need to run the engine at 2000rpm for a long period to let it all bed in. Im wondering if my new push rods have moved things and loads around.
    Im also still worried the rod guide plates are rubbing on the new rods.
