I've been trying to post this on Paradise Island Cruiser's forum, but I forgot my password. The problem I got encountered goes like this...Yesterday, I installed an "air-raid" throttle body spacer for my 1993 Chevrolet Z71 with an otherwise stock (LO5) 5.7L V-8 engine. A 1/2 inch diameter "flat" washer fell into the intake manifold while trying to put the TBI unit back onto the intake manifold. Thinking nothing would happen, I bolted everything up, I started the engine, and now it makes a ticking sound "more like a washer being bounced around. I immediately shut it off, pulled all the plugs, and #8 plug had a bent ground and was against the electrode. I tried putting a flexible magnetic tool into the combustion chamber, but nothing came out. I think Ill have to pull the cylinder head off. This I never done before, Hopefully Mr. Villacorte of RC Automotive can remove it.
