montego8 Posted June 20, 2012 Report Posted June 20, 2012 Well I got my 50 dodge wayfarer inspected and went on a few break in trips to test it all out and everything was great. It's all original, except I put disc brakes up front and a dual master cylinder. Boy it brakes nice steers nice and,after new springs, rides like a dream. We were planing a longer trip when the motor started knocking.I stopped the car and by the time I lifted the hood the noise went away. So down the road I went. Ten or so miles latter the same noise. A loud and fast knock. Push the clutch in and it knock slows down but is just as loud. I got the hood up quick and the sound is in the motor and I think on the top? I got in and tried to get a few miles to my dads place and the noise went away. So I drove it home. I can start it up and most of the time there is no noise. The oil pressure is 40 Lb. and the temperature is fine. It has a little blow by and the oil pan leaks some. It does not look like it has ever been apart and has 87000 on the odometer . Any thoughts? Wrist pin is my guess,but I never had a flat head motor apart. It looks like the oil pan would come straight down and the head straight up and off! One by one removable of the pistons and the valves can be left alone,I think. Quote
Plymouthy Adams Posted June 20, 2012 Report Posted June 20, 2012 could you have freed up a piece of carbon in one cylinder and caused the knocking sound..have seen this many many times when a car is often run a bit harder than the PO ran it or after sitting a long time and getting started and up and running..

montego8 Posted June 20, 2012 Author Report Posted June 20, 2012 That,s possible. It did sit for ten years and the noise came the first time I got it up to highway speeds. Well ,I was going 60 anyway. But the noise sounds so like metal on metal? Like some guy is in there with a small ball-peen hammer and is rapping on the inside of the head. Quote
Plymouthy Adams Posted June 20, 2012 Report Posted June 20, 2012 sounds like you have never heard carbon knock before...I have had it happend a number of times with Ford 460's (notorious for that) in the Town Sedans and Mark series..we at the shop tune them up..test drive..(yeah we floor them) and man it sounds like it's coming apart...nothing a coke bottle full of water won't cure..

montego8 Posted June 20, 2012 Author Report Posted June 20, 2012 Please explain.(.nothing a coke bottle full of water won't cure) ,Sounds like a cheep remedy ! Quote
1941Rick Posted June 21, 2012 Report Posted June 21, 2012 Was a cure for gm's running on....with the engine at a high idle slowly pour a bottle of water down the car. The water will break the carbon loose and blow it out the tail pipe. Now for stubborn carbon you do the same thing except use small grain rice. Just like sandblasting but not as agressive. Worst that can happen is the rice gets packed into the carbon. But in that case the head has to come off anyway. Quote

Water flashes to steam and steam cleans the combustion chamber. I dont believe steam will get packed into the carbon. Plugs might get fouled but a bit of sand blasting will clean them. Quote
1941Rick Posted June 22, 2012 Report Posted June 22, 2012 Was a trick we used in high hour diesel engines. Got rid of the carbon prior to a rebuild. Quote
greg g Posted June 29, 2012 Report Posted June 29, 2012 Rice??? Popcorn would be much more fun..... Quote
Don Coatney Posted June 29, 2012 Report Posted June 29, 2012 Rice??? Popcorn would be much more fun..... Hy-jack attempt! How and why did popcorn get attached to movies? Quote
greg g Posted June 29, 2012 Report Posted June 29, 2012 Many theater owners did not allow popcorn into their theaters. Those that didn't soon lost business. Most theaters did not have their own poppers, and partons bought the snack from nearby storefront or street vendors. Smart theater owners noted that they could make more money from popcorn sales than from the movies themselves, and installed poppers. This was especially true during the depression years when popcorn consumption (cheap and filling) increased dramatically while other snacks, pretzles.goobers, ju ju bees' , and non parials, stagnated or died. Plus the salt in the popcorn stimulated beverage sales also. So for 15 cents the movie goer got a flick, a beverage, and a reasonably full belly. Plus a little relief from their personal strife.

What I find interesting is how the movie houses today advertise popcorn and soft drinks. They show a film clip with sound showing every cournel of popcorn exploding perfectually and the sound of Ice dropping into a glass made of real glass (not a paper cup) as if that is what they have to offer. What they actually sell is butter flavored grease topping for the popcorn and watered down drinks in a paper cup for a very inflated price. My mom filled a paper grocery bag with stove top (not the microwaved crap)popcorn, and sprinkeled it with salt everytime we went to a drive in movie. If I recall it tasted much better than the stuff for sale today. And today the popcorn and soft drink cost exceeds the cost of the movie. Quote
greg g Posted June 29, 2012 Report Posted June 29, 2012 My father ( a child of the depression) was a popcorn afficianado, so much so that he and his father grew their own, two or three varieties. the had enough that they sold it by the pound at a roadside table, and had people coming from all over the county to buy it. Sunday evenings at least two or three times a month were popcorn for dinner nights. This usually followed a large breakfast or a large lunch. Popcorn, sliced apples, chedder cheese, and Iced tea were the usuall fare munched down while watching Disney or Ed Sullivan. He had a hugh stainless steel bowl that got filled from three or four batches in a stove top popper. My grandmother always made Popcorn Balls for give away at holloween, Popcorn, butter brown sugar or mollasses heated into a soft candy form and poured over freshly popped corn, then made into snowball sized treats wrepped in wax paper ad tied with twine. Christmas tree always had strings of popcon on them. and more popcorn balls as presents and stocking stuffers. I still buy regular popcorn and use an air popper and can;t believe its butter and light sea salt. Not three times a month bu probably a lot more often that other families. Lets go out to the lobby, no thanks, smuggled in my own.... Quote
