  • I need help!

    I have a 1962 wagon with a full flow engine (Ov6) auto trans.
    i parked it in my garage for about two weeks
    we had a local car show & I went to take it out for the show
    and found I had a bad rod knock in it, plenty of oil in the pan
    up till this time it has run real smooth
    any Ideas to the cause of this
    thanks
    John

    Impossible to tell, (most likey just normal wear and now you have excessive rod bearing clearance) until you find out exactly what is knockingEven then you may never know what caused it. Thats the way these things happen, one trip their fine, next time you start it you have a leak or knock.
    Good luck

        Low or non-existent oil pressure, when you turn on the key without starting, does the oil press. warning light work?

        The other reason is WEAR or corrosion, the bearings have been in there too many miles or too many years!

            check your oil pressure, if it is good it could be a carbon build up.

                Hey John, are you sure it's a rod knock? I thought my car had a bottom-end knock when I got it, and it turned out to be a cracked flex plate. Does it go away as revs increase? Have you tried pinpointing it with a stethoscope?

                    I thought about the flex pate and got a new one from stude int.
                    wheh you turn the key on to start it, the motor rocks and the rod noise
                    if thats what it is.
                    after it starts the noise does quiten down ssome

                        Start her up and keep the trans in park, then slowly increase revs.

                        - If it's rod noise, the sound will get louder and the vibration harsher as engine speed increases.
                        - If it's a flex plate, the sound will get quieter and vibration smooth out as the engine revs higher.

                            The wagon is my old car. It did that once before, don't panic. It made a horrible hollow clunking noise. (the right tranny mount failed and was letting the exhaust pipe contact the crossmemeber). I would suspect its the right transmission mount, Both mounts were replaced in January with new parts supplied by studebakers west. You'll find the receipt in that manilla envelope. The shop that put them in said that the right one was hard to install. I would suspect that that is the issue. How is the car doing for you? I miss it a lot.
