Have this summer bought a 59 Galaxie with a 292/auto trans. Sometimes I get a metallic clacking sound from it, Oil press is 4kgs cold, 3.5kgs varm. It cant be bearing related, oil press would not be as good if a bearing is gone. The clack doesnt seem to be engine temperature related, its seems to bee random, just comes and goes, maybe a bit better when warm. Since this is my first Y I send out the question to you. This weekend i will listen whith a stetoskope, I have had several Ford SBs an whith a SB i would know what was the source to a sound like this. Have also suspected that it is something in the auto that sounds. Well, before I tear it down, any tips or someone have experienced the same? Will anyway rip off the heads since it blued a bit when it got varm in the cues when we where at Power meet this summer. It otherwise runs really well and takes of suprisingly well. Regards Mr Sweden/ Per in Uppsala Sweden.

Check the valve adjustment. A little clacking is normal with a solid lifter engine. It can be worrisome If you're accustomed to small blocks with quiet hydraulic lifters.
The spur gear oil pump can do it, and it does not necessarily indicate that something is wrong.

No its not not the valvetrain or the adjustement, The first thing I do when I buy something is to " sero" it, that is adjust and change everything. I Have had different american cars for about 30 years, always done everything myself, (also whith my beemers). It is something else that disturbes, would like to have more tips and experiences before I pull out my wallet. Anyway Big thanks, this whith that the world gets smaller whith i net is sometimes very nice, aspecially when comes of loving cast iron. Regards Per

It comes much faster than any of my small blocks up to pressure (oil), Please explain spure gear. Regards Per.

Sorry, I have to ask, did you notice it before changing everything? And just to avoid further confusion, you didn't adjust the valves to "zero" did you?
Someone else here experienced something similar. It turns out that rivets on the transmission flex plate came loose and were causing the problem.

A spur gear pump is the first picture. They simply call it a gear pump:

Could it be an exhaust leak?

My brother had an annoying clack in his 65 Comet 289. It was intermittent, sounded like a wrist pin. Turned out to be the choke butterfly in the Ford flat top carb.

Charlie, thats what crossed my mind, i know its hard with the language translation, but think we need to know a bit more info on when the noise happens, i.e, on take off, during acceleration, low idle, or higher rev range, putting it into gear.?? look forward to ansewrs.

I’ll suggest looking at the flywheel and converter area first for your ‘clacking’ noise. Need more details or description though as it could be as simple as an exhaust leak and don’t rule out an exhaust leak at the crossover heat passage at the intake manifold itself.

No, correct valve lash had to loosen a couple or so, have also suspected a bad wrist pin bushing, What is so strange is that it comes an goes. This summer i put something like 500 miles on the odo. if it was serious, things should have gone worse fast. Sometimes clack when cold, sometimes when warm and vice versa. Tomorrow evening i will stetoskope it an find out if it follows rpm or, just like the doctor taking pulse. Another thought is if I have a cracked piston.

More ansvers, does not clack when I step on it, seems to come mostly in idle, Ign 10 before, Definetly not exhaust its to metallic. I will inspect the converter and flywheel for cracks. One problem I have is that my ears aint what they used to be. Otherwise it runs suprisingly well. I actually dont know if its a 292 or a 312. 4bbl intake vere its supposed to be a 2bbl. Regards Per.

Hi Per I have had the same problem with my Pontiac 326 cui. Clacking sound on idle and on even rpm and no sound when stepping on. I run with it one summer before i took the engine apart and really regret that i did so. It was a rod bearing that had rotated. If i had take it apart at once it had been enough to buy some bearings and some gasket but instead i had to spend money on new rods and a new crankshaft, so be careful. Ni har väl snö nu där uppe så du kör väl inte nu ändå, eller du har vinterdäck på Forden Nonne

Oh... those swedes... Good to have more swedish Y-blockers here too. Loose converter bolts?

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

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 .

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.

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

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
Regards

I'd vote for a problem with the flex plate. We've had the same symptoms on a couple of Tbirds in our club. Fireball 56

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

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
