get a new tappet.... I have heard that the old one will just sit in the bottom of the pan....

You might try to look at where the dipstick goes into the pan.... there is a known leak point there and that says to me you can remove it and fish with a magnet.

Do note I am guessing from what I have read and have never done this. I do know you have to pull the engine to pull the pan....

Spin the engine by hand a few times to make sure its not binding up. If no binding then don't worry about it.

Was it the new or old tappet?

I have seen some thread where people turned the motor over by hand and listened for it to drop in the pan...

BUT... I may be giving you very bad advise... wait for someone else to chime in...

Is almost impossible to know that, but I have read several cases like yours, and no one has reported any issues to my knowledge. They have left the tappet there and live with that.

One question, the harmonic ballancer was at TDC when this happended?

I went ahead and put the old tappet on the new pump and installed it. truck started fine all seems well. Thanks to all, and sorry about the stupid questions. I am learning as I go on this truck. this site has helped tremendously, the goal is to ask less and less stupid ones as I go but..., no promises, lol

Whew!

"Harmonic balancer" is just another term for the crankshaft pulley. José wanted to know if the crank was at TDC.

And my apologies for stirring up all the drama in your thread; I honestly had no idea that, by re-iterating what the esteemed Mr. Action himself stated in another thread a year or so back (that turning the crank to a certain position only gives you a 50/50 chance of the lobe on the cam being in the right position), I would be swatting a hornet's nest. And to anyone I might have chased away from here, as I've been accused of, further apologies.

The added weight of the tappet sitting in your oil pan should have minimal effect on fuel economy....

Yes I wanted to know if the Harmonic balancer or crankshaft pulley was at TDC, because I remember that old thread about the 50/50 chance and if you put it at TDC you went in the bad 50%.

PS there are not stupid questions here, and we are always learning here in FTE.
