Default Need Help Quick Please!

I was in the process of changing my wife's valve seals. Started on the exhaust side of #8. Had the air hose connected in the plug hole with 90psi. Popped off the seal and was not able to catch the valve before it dropped. I can not see the valve anymore but when I stick a pen magnet down the hole I can feel the top of it faily easily (without the magnet going too far down). Is there any way at all possible to get this valve up without pulling the heads??? Any help would be greatly appreciated!

how far down is it,can you turn your engine over with the crank bolt to lift the valve with it on the magnet at the same time????

Well, to prevent any more of those problems I used both the air and the top dead center method to finish up the seals and when putting on the springs.

You got lucky my friend! But I am glad for you. I have never had a problem doing valve spring or seals with air. But then again I am luck also.

I don't know how you pulled that off but you should have bought a lottery ticket when you did that.

just a note : I use air and TDC both but the air rolled the piston down ( at 60 psi and all plugs in except the one we were on)we had left the second spring fron rear off while removing the rear spring, some way bumped the value and lost air pressure and ALLMOST droped both values on that cyl.
so you need to watch that the air does not roll piston down ( on my car 59-60 psi will roll piston to complete bottom- 51 k on car, a4, and use no oil )
just my .02's Johnny

I disagree about it being a miracle...I've seen that happen like 4 times now (on various cars) on an LS1....and I've *never* seen it fall all the way in. I'm not even sure its possible now after that kinda record.

Either way, as others said, turn the motor and it comes right back up.
