Ok so its been a long week at work with thing after thing breaking, I.E. an M-22, broke my press, and my finger. I went and got a customers '53 ford truck with an 8BA cause he couldnt get it to start, been sitting for a little over a year, Oil pan was leaking, so we replaced it, and cleaned out the pan, cleaned out the fuel tank (nasty varnish gas), cleaned out the fuel pump, rebuilt the carb (it was full of trash and the float was stuck), had to take the distributor out cause he had messed with it and was no longer on TDC for #1, points were fried, new cap, new ****on, new starter relay, and all that good stuff. Anyways, I got it started... Sounds HORRIBLE!!! Got my compression tester... No compression on cylinder 3 and 6... I think the valves are stuck, filled the cylinders with Marvel Mystery Oil and letting it soak... Anything else i can do short of taking heads off?
Filling the cylinders with oil won't do anything for the valves. Pull the plugs. You will be able to see one of the valves and maybe a corner of the other one. See if the one that is visible is hanging up. If so, carefully tap it down, crank it over, keep tapping it down till it hopefully frees up. Otherwise , pull the head. Also, could pull the intake to see if any valves are sticking.
Thats what I think he Means, here I thought I was going to see something realy Special that I never Heard of oh well just my 3.5 cents
On a flathead Ford V8, leave the heads on and remove the intake. That is far easier, and you can see which valves are stuck and deal with them. The gasket may be able to be saved, costs less if you need to buy one, you dont need to drain the coolant, and there are half as many bolts.
If you can see the exhaust valves by taking off the intake, you've got a relatively serious problem........
huh. you must have discovered some top secret engineering defect with every single flathead v8 ever made lol
+ 1 on the above. To verify it's a valve before starting that you might try putting air into a cyl in question at TDC through a plug hole adapter and listening to the intake and exhaust ends for leaks. Air into the pan could indicate cracked or holed pistons. Bubbling coolant could indicate cracks into the water jackets or a bad head gasket. Ed
Jeez, what the hell was I thinking? Didn't even consider you can see the stems in the lifter valley, was just thinking about looking down the intake ports. Old man brain fart, I guess.
Ok... Sorry for the misleading headline, just thought it would get attention... So can i pull the intake off instead? Its much easier to get an intake gasket than head gaskets.
Speaking of those.... they were used by snowplow trucks to run the sand spreaders on the back. And during sitting all summer, the valves would be stuck open. The shop guys just bent up a stiff screwdriver to get through the plug holes. Almost always worked.
So i pulled the intake off, Intake on #3 was stuck, made a tool that freed it up beautifully... Piston #6 was a different story... it was closed and bent, the keeper was shattered. Drilled and tapped the valve, threaded it to 1/4 20, put on my slide hammer and removed the whole valve ***embly. Had a spare sitting around. I took out the lifter to check it, was scared up, put a new one in, new valve ***embly, everything clearenced and ready for new gaskets and be back together... Much easier fix than i was expecting... Thanks for the help guys
That was a German engine originally and was used in some models of their cars like a Taunus I believe and Industrial engines worldwide and was the basis of the V6 used in the Capri.
Didnt think it was a v6... It was a V8 with 2 dead cylinders... but both were on the inner cylinders. Cylinders 3 and 6. Does any one want pics? Including tool i made?
Digging up a old post here, but hoping someone may know what this is I believe it to be a flat head v6 but never seen anything like it, there’s 3 plugs and 3 injectors and the exhaust ports are labelled 1 2 and 3, does any one know anything about these.
