pumppy10 Posted March 31, 2013 Report Posted March 31, 2013 hello there, I have a 51 concord with the original flathead in it, was out driving the other day and started to hear a ticking noise, almost sounded like a throwout bearing going deep six on me, very shortly after I picked up a miss. checked plugs and wires, all ok. any ideas on where to look next?

Don Coatney Posted March 31, 2013 Report Posted March 31, 2013 Pull the head and see what piston has a hole in it as pictured below. Then be prepared for a rebuild. Been there, done that. Quote
1940plymouth Posted March 31, 2013 Report Posted March 31, 2013 (edited) I second Don's advise, I am in the process of installing new bearings, both rod and main, plus new pistons and rings Edited March 31, 2013 by 1940plymouth Quote
Dave72dt Posted March 31, 2013 Report Posted March 31, 2013 Why not try a compression test before gutting it. It should give you an indication what cylinders to look at. May be just a blown head gasket. 1 Quote

May be just a blown head gasket. Compression test is good but I have never known a blown head gasket to "tick". A broken ring on the top of a piston will tick. Quote
pumppy10 Posted April 1, 2013 Author Report Posted April 1, 2013 cool, now I have a reason to yank the motor and give it a good rebuild. I have never torn into flathead before so this should be a lot of fun. cant be any worse then the caddy northstar motor I rebuilt a few years ago. any tips on what to watch out for, any weird stuff in there?

Dave72dt Posted April 1, 2013 Report Posted April 1, 2013 Compression test is good but I have never known a blown head gasket to "tick". A broken ring on the top of a piston will tick. I've heard all kinds of different terms used to describe the same sounds. Knocks and ticks may describe the same sound by different people as may whistles and squeals. Quote

Knocks and ticks may describe the same sound by different people as may whistles and squeals. Good point. Sounds are different to different folks. But I do believe he has a broken ring land on one of his pistons. Have you ever had this hppen to one of your engines? Quote
Dave72dt Posted April 1, 2013 Report Posted April 1, 2013 Yes, I've got a tick tick tick in my daily that sounds like a sticky tappet but I know is a small ex manifold to y pipe leak and a head gasket leaking out the side sounds similar. Onan 2 cyl air cooleds were famous for it. You're probably right on the rings being the culprit, I've seen that too. Usually end up with a lot more blowby coming out of the engine when that happens.

pumppy10 Posted April 4, 2013 Author Report Posted April 4, 2013 found trouble, blown head gasket Quote
pumppy10 Posted April 4, 2013 Author Report Posted April 4, 2013 am not sure if this right, #1, 2, 4 and 6 pistons have small indent in center of piston are just flat tops with no indent, this sound right? Quote
pumppy10 Posted April 4, 2013 Author Report Posted April 4, 2013 (edited) sorry, meant to say that 1,2,5 and 6 have indents, 3 and 4 are flat across with no indents. this is the second time it has blown a head gasket around the same area, i'm thinking warped head maybe. what is a better choice for the head gasket, stay copper or newer style? it blew between 3 and 4. i'm guessing the ticking I heard was the piece of copper bouncing around until it went out a valve.

Don Coatney Posted April 4, 2013 Report Posted April 4, 2013 Glad you found it. I was incorrect in my theory. Dave 72 nailed it. Quote
pumppy10 Posted April 4, 2013 Author Report Posted April 4, 2013 thanks for all your input don, I was kind of looking forward of doing a rebuild, but am glad that I see no broken pistons. Quote
greg g Posted April 4, 2013 Report Posted April 4, 2013 (edited) Have your head shaved around (30 to 50 bucks) at the machine shop, then check the block with a straight edge and a feeler gauge to assure you don't have a dip or a high spot in the block. And as long as you have the head off and at the shop, you might as well have a good bit take off and raise your CR a notch or two. Edited April 4, 2013 by greg g Quote
Solution pumppy10 Posted April 10, 2013 Author Solution Report Posted April 10, 2013 Well, had the head shaved, was warped pretty bad, but not beyond repair, fired her up tonight and she purred like a fat little kitten. Time for some summer fun now. Quote
greg g Posted April 10, 2013 Report Posted April 10, 2013 Toggle the answered flag on this thread so folks no your back in the saddle, Nice to hear it worked out. How much did you take off? Quote
JerseyHarold Posted April 10, 2013 Report Posted April 10, 2013 Good looking business coupe. Original paint? Quote
pumppy10 Posted April 11, 2013 Author Report Posted April 11, 2013 since I am only the third owner, and the last one had it for over 25 years, I was able to get a little background on the car. was told that it had been repainted in 1954 and some body work was also done then. they must have done some pretty good work as it is holding up pretty good. Pervious owner rebuilt engine but kept it stock with no performance done. Car has been kept as close to original as possible. Last owner kept it garaged so i'm sure that helped keep it as nice as it is. I am also keeping it in the barn to protect it. Quote
Scruffy49 Posted April 11, 2013 Report Posted April 11, 2013 In the barn? At my place here in west Tennessee the wood boring bumblebees would have it buried under dust and wax inside of a month. And it would be filled with mice, mahogany wasps ( curious, but not aggressive until really pushed) and either a copperhead or a cottonmouth. My 49 truck was barn kept in western Washington, the seat was full of hazelnut shells (squirrels) and the bed was usually full of potatoes or kittens. For 20 years. Quote
pumppy10 Posted April 11, 2013 Author Report Posted April 11, 2013 I'm up in the barn everyday working on one thing or another, so there's always some activity to scare away the pest, as for snakes, well maybe a Gardner snake but we haven't had anything around here in years,, had copperheads about 5 years ago but they haven't been around for quite some time. I also keep a cheesecloth sack full of rosemary in the car, that keeps unwanted critters from nesting, not sure if it really works but was a tip I got from an old guy who stored his model A in his barn, so far so good.

Sounds like a good idea. Where can one get rosemary in the sack? Quote
greg g Posted April 11, 2013 Report Posted April 11, 2013 Look up bucket trap on the interweb. Rosemary is also good, according to Native Americans, for warding off evil spirits, and skinwalkers. Might work on electrical gremlins as well..................hey Don at your age you should be more concerned about getting out of the sack n the AM rather than whom may be there with you!!!! Quote
pumppy10 Posted April 12, 2013 Author Report Posted April 12, 2013 wow, I'm glad I didn't use NUTMEG, I can just guess what kind of replies I would get for that LOL! Quote
