Sorry guys In a hurry and need a quick response.

Well here is how things go, my moms boyfriend bought this truck before he passed on ,during this time, he re-built the whole engine just before he died.

He started it for its first time after being rebuilt & when doing this he bent a push rod (piston rod ?) not sure.

You can tell from the knocking, plus, he knew he had done it.. Well a few months & almost a year later i get my license and my mom says i can have the truck.

Well, I've started it a few times to let it run because somone told me that i should let the oils run through the engine because it was good for it.
So today, I let it run for around 15 min (until i ran out of gas).

I went to the gas station filled up a gas can and came home.

When i put the gas in the tank, i couldnt get the truck started again, I even primed the carburetor with some gas & it still wouldn't start.

So here is my question :
Could I have caused some damage by letting the engine run with a bent rod?

Either way, I was wondering if anyone could guess how much it would cost to get the rod fixed?
And maybe explain how the piston or push rods work.

 

It is pretty hard to bend a piston rod but you should find a mechanic to give you some help finding out which it is. The cost of repairs will vary greatly depending on what it was. Getting your engine started after running out of gas can be difficult.

 

Thank you for your help. Im almost 100 precent sure that it was the push rod. So you dont think i could have caused any damage to it by running it

 

If the push rod popped out and the lifter pushed out you could have run into a no oil pressure situation. If you can still turn it over it probably has not happened. You need to get a mechanic to look at it.

 

Short answer ...NO ..

The push rod is usually replaced with the rocker arm as well.

All The push rod does is a be the in between guy of the lifter & the rocker arm.

The reason a push rod bends is either because someone had done some head work (new valves ) or valve work and didn't allow for the change in distances when installing the pushrods. Or, the engine was run at a very high rpm.

You first have to establish if the engine has work done to it then measure the rod length against the others.

This could actually be placed in the applicable engine forum.

It has nothing to do with the truck it's in.

 

Well I got it started and took it around the block a few times

I found some notes that he had made and they said he did bend the push rod & that he was ****** off because he said he made a novice mistake.

 

Is it a bad thing when black smoke comes out of the tailpipe ?

 

Not necessarily. After sitting for some time, the Carb may need a cleaning and rebuild.

THis also MAY be caused by fuel being dumped in the cylinder by the good valve for that cylinder, then possibly not getting the proper amount of air to burn it. Maybe its opening enough to exaust the spent but not fully burned fuel.

I could be off here. I havent had much practice on engines lately.

I would start pulling the carb,, then the head, and checking it out. I good Head shop will hook you up.

Blue smoke = Burning OIL

Black Smoke = Too Much Fuel

White Smoke = Quick shut it off & park it (Coolant in combustion chamber)

 

Well i think it was too much fuel because, I had to pour some in the carb to get it started and i accidently poured a lot.
After I saw the smoke,I shut it off and pulled off the air filter to look at the carburetor and there was smoke coming out of it as well.
It was just a little bit and it was white?

BTW he rebuilt everything carburetor as well.

 

I bought an F350 six months ago, and it had just about all of the problems listed above. I had a bent pushrod, smoke, you name it. The blue smoke is a good thing, it cleans out the engine. I had black smoke coming out when I was getting 4.7mpg, and I had the white smoke last week - I think that might be a valve seal. I would take the truck to a good mechanic and he should be able to nail down the specifics, and then you can pick it up from there.
