So now I feel like an idiot. While putting the top half of our 4L back together, the socket fell into the manifold. Tried using a magnetic grabber but couldn't find it, so tore down to the rockers. Still can't find it. Anybody have any ideas that don't involve tearing the whole thing apart?
When you say tore down to the rockers, do you mean you removed the intake? If it went down the intake runners than it can only head for a cylinder with an open valve right? The rockers would tell you which cylinders are open.
How big was the socket? Size would limit the possibilties.
Just thinking out load, but if it's small enough to pass a valve then maybe you could retrieve it through a spark plug hole. Pull all the plugs and gently rotate the engine till it obstructs-then the socket should be at top dead center close to the plug hole. Then maybe a magnet might work. How small a socket would pass a valve?
The #$*## socket is a 7/32, small enough maybe to pass a valve, and no, it's not in the toolbox, that would be far too easy. I watched it drop down the intake runner. What is a borescope?
I don't think a 7/32 socket would pass the valve seat, (why a 7/32 there all metric in there). It must be in the intake maifold some place, have you tried on of those thin 4 prong grabbers they expand when you push the end and you can get them from sears or any well equiped auto store, plus there bendy so you can get them around cornners I have used mine many times to retrieve lost nuts and bolts. One other thing though if you have turned the engine since you lost it may have got jammed between the valve and seat, but then you would have a tight valve spring were you should not.
a 1/4" inch drive socket is over 3/8" in outside diameter on drive end....never pass intake valve...still at the bottom of the head passage runner against the intake valve...are u sure which hole?
use a pickup magnet on a flexible shaft and search until it comes out....will take the head right off a valve
Finally go it out! It was wedged pretty well in the intake valve, but what a pain to get it out, spent many frustrating hours with flexi magnets, grabbers, fingers, etc. Now to put it back together. Thanks for all the advice.
glad you got it out, I had a teacher in high school drop a small 3/8 in wrench in the intake before putting the carb on his Chevy 350, the valve snapped the wrench in half and it bounced around different cylinders until he shut it down. beat up the pistons pretty good, bent the valve, put a new valve in and called it a day. He said no major scoring on the cylinder walls. He was lucky. He sold the truck some time later. LOL.
It's one of those things you hear of but only happens to other people. Now that it's over i can laugh, but at the time I though maybe alot of swearing & threats would convince the engine to cough it up lol
