So, started it in -5 celsius yesterday, clacked for a longer while than usual, and yes sound comes from the rear of engine, or oilpump side. Now it will rest in the garage for a while, snow warning for tomorrow. Will propably buy a new oilpump, just to be shure, if we get more of these clear and dry days I will drive it in to work again and rip the auto off for a thourough inspection. It is also very difficould to listen out a sound that comes and goes randomly. Will also take off the heads and take an inspection and a slight cleanup of the castings. Guess that there will be some casting edges to grind off. Regards Per

If we're running a poll, I'd vote flexplate. Been there, done that.

I'd vote for a problem with the flex plate. We've had the same symptoms on a couple of Tbirds in our club.

Surely if you are out driving on a sunny 8 degree day, you would not hear a thing. I would be wearing ear muffs. Too cold for me. A loose flex plate is one of the scariest sounding noises you get out of an engine, but is probably the easiest to fix.

Good luck

Jodå Nonne i dag har vi varit ute och åkt, Sol +8 torrt här i Uppsala, har lyft å så på jobbet, gäller att passa på innan den stora vintern kommer. Mvh Per. For You not swedish speakers (If they only could use Swedish as an international...) Ive been out driving on a quite beatiful automn day, sunny, +8, dry, my elbow got frosen, Go Getters in the stereo.... Nice. Per

Timed it, half the RPM approcimately, so it cant be a wrist pin or a bearing, dissapears when reving up, camshaft related? fuel pump (augt to sound the whole time). This is strange! Regards Per

Hello again! I have now first of all completed my zeroing, the last thing I changed this evening was the ignition cables. It had some trouble getting the right ones, ewen if you say when tou order that IT IS A Y BLOCK NOT A SMALL OR A FE, I twice got cables for a SB. Cables were of course off in rhe distrbut, 3 of them, and stiff and old as H... The clack actually got a little bit better after the change. Have also listened to the engine whith a real doctors stetoscope, and of course to solid iron not on the valve covers. (and suitingly of course dressed in a white coat, unfortunatly not whit a doctors paycheck in my pocket)=). Well, not a strange sound anywhere, just cam noises and valvetrain sound not out of the ordinary. If it is a rod bushing I guess one should hear it, and as I mentioned before the oilpress is very good. Will not lift it tonight since I often stay fridays at work have a couple of brews and do some mechanics. Yes the clack, when it comes sounds like the whole bottom is gone, will check the flexplate tomorrow. It is in my mind impossible not to hear a wrist pin or something else vith a stetoskope. The story goes on.. Thank you all for you comments and thoughts. Regards Per. PS for you americans I wold like to teach some finnish, A very good sentence to know is: Minen kyrpä maista mansikka. And I got sick humor/ hope you didnt take that bad my finnish neighbour.

Per ,

I had a  really bad bush in a dizzy once .It would only last for a couple of seconds ,then run as quite as a mouse .The other "bad " noise was from early flexplates .It was real hard to pick the noise as it would only last for a few seconds .Sounded like the whole bottom end was giong to drop on the ground at any time .It got the the stage where Lynne refused to drive it ,until it was fixed .Good luck .

I think that '56 was the last year of riveted flex plates.
