    Any ideas to what this ticking sound could be?

    Oil is full and clean. The other engine does not make this sound. It runs like a champ, no problems just wondering what the sound is.

    I really can't tell by the video but I can offer an opinion. I had a similar thing happen to me on a 1974 crusader a few years ago that sounded kinda like a lifter clicking and it was coming from the front of the engine. Mine ran great no problem other than the clicking noise, I asked my best friend who has been a mechanic all his life to check it out and he was as puzzled as I was. We traced it down to the timing cover area and after we couldn't stand it any longer we finally took the front end off and there was a worn spot on the inside of the timing cover. My engine is counter rotating with gear drive camshaft and the trush plate holding the camshaft in was worn letting the camshaft gear rub the timing cover because of a worn cam lobe. I replaced the camshaft and wear plate and it is still running today. Come to find out some other crusader owners told me that they have heard that they were bad about the lobes wearing because of the fuel pump rods and low oil supply at low idle for what thats worth. I always crank mine up and then rev it up to about 800 to 1,000 rpm's at idle now. B.B.....

    Sounds like an exhaust leak but it could also be lifter noise. Of the two.....I would rather have an exhaust leak. Get a 3' piece of 1" or 1.5" PVC pipe and see if you can locate the sound.

    To all the owners of "older" engines with "flat tappet camshaft" it is imperative that you use oil with the zinc additive. The zinc additive prevents excess wear of the camshaft lobes and lifters the caused the above problem. I use Valvoline VR1 racing oil. It's not cheap but well worth it. Most motor oil does not have the zinc additive as it was removed many years ago because it damaged catalytic converters in modern cars.

    I don't hear anything abnormal, but one thing to consider is your spark plug wires. A 7.4 will make a ticking sound if an ignition wire has broken down to the point where it is arcing to the block, head intake or another good ground.

    Try running the engine making the sound at night with no light on. The mechanics at the marina told me I needed new plug wires on a pair of 7.4's and I thought yeah, sure and your kid probably needs new shoes. He is a salty, no B.S kinda guy, and he told me to look a the engine in the dark and tell him what I saw before I appologized. Sure enough, the 7.4's, even though they ran perfectly at all speeds, lit up like a Christmas tree.

    Off the shelf Castrol or most oils do not contain zinc any longer. You have to buy oil that is labeled and marketed as having the zinc additive or purchase the additives which are widely available. When using the additive make sure you follow the manufactures instructions. Too much zinc is not good for the engine as well. I order the Valvoline VR1 from Amazon. Places like speed shops or auto/truck accessory stores usually carry it. Napa is another good place to check out.

    I had a 454 in my 270 that made a ticking sound like that... turned out to be a cracked harmonic balancer.

    Thanks for the zinc info in oil. Do you know if zinc is still in diesel oil?

    I wouldn't bet on it. I would check the manufacturers web site.

    I had a leaking exhaust manifold (at the gasket) and where was a ticking sound... I replaced the gasket and the ticking went away...

    hottoddie is absolutely correct.

    I run either Joe Gibbs HR1 oil or Brad Penn High Performance Oil (the green stuff). It's expensive, but the high zinc is absolutely needed with our older motors.

    Tough to tell from vid. Would agree it sounds like an exhaust leak but am a bit curious why you are focusing on the rear of the engine? Other than frequency, how does the sound change with load and rpm?
