Default Help!! Screw in engine...accidentally

I dropped the distributor cap screw down the hole when I was tying back the cap to keep it out of the way, so I could put new dist. in.
What can I do?
Thanks

Tear the motor apart and rebuild

Pull the distributor and get one of those telescopic magnets and see if you can fish out the screw..

I would start with a flashlight and see if you can spot it. Get a magnet on a stick. You can get them at auto parts places or a hardware store. and if you seen it. pull it out with the magnet. If not fish around with the magnet. If that don't work, then pull the intake manifold. But whatever you do, don't run the car with it in there.

just a magnet with a light as the others have posted. pulling the intake won't do much good since the hole through the block is the same diameter as the intake.

I'm kind of old school does the distributor still engage the oil pump drive? Maybe it fell down into the bottom of the oil pan. You know you needed the change the oil anyway.

I was going to say, turn the motor upside down and shake it.

You got lucky. Years ago when my son was about 4, he loved to help "Dad" work on the truck. I had just built a new engine with cam etc and had dropped it in. The very last thing to do was drop in the distributor. I could not find the lock down bolt. He had been crawling around in the engine bay. I took a flashlight and looked down the hole....DAMN...he had dropped the bolt down the hole. I tried a magnet...that didn't work. I ended up having to pull the pan. He is now a car fanatic and has my built 85!

I guess suggesting to turn the car over and shake it, is no longer needed.

As long as you cannot see the screw when you look down the hole with a light, it may have fallen straight past the cam gear the oil pump drive slot and into the sump. as long as it fell into the sump you should be right maybe put a magnet on the sump to hold the screw till you drain the oil.

Not hard to remove the sump with engine in the car drain it first and see if the screw came out, remove starter and flexplate shield then remove the screws and drop the pan. remove the screw (it could have fallen on the crank splash shield so feel on top of there). Then fit new sump gaskets and put it back together.

Couple months ago was putting 383 back in my vette, when installing the tpi runners a young guy helping me dropped a plastic gasket retainer down the intake, ofcourse the intake is ported so the plastic holder when all the to the intake valve.

I got really lucky it was the #1 cylinder and it was the intake valve - engine was at TDC. However the retainer is plastic and you couldn't see it nor could you reach your hand in there.

So I did something that shocked my wife, for the first time if 15 years of marriage I asked her for the vacuum cleaner, her face lit up, I guess she thought I was in a cleaning mood. Not so much, I took the hose attachment stuck it into the intake port and put duct tape (no really, duct tape) around the intake and hose attachment to seal the port, and fired that sucker up. It took about 30 seconds of fishing around be we got that gasket retainer back and then I asked him not to use them any more.



Just goes to show, guys can use vacuum cleaners....

Just sayin....

Yo Joe! With your luck running like that? Be sure to buy a 600 million dollar power ball lotto ticket for tonight. Don't forget your old buddy Mark who suggested it........
