Hello
I was working on a 04 blazer 4.3 vortex when a very small tip of a screw driver broke off and went down into the #1 cylinder fuel port! I set the motor to tdc and removed the lower intake but can not locate it. I tried probing around with a magnetic rod and tried fishing it out thru the spark plug hole with no luck! Any one have any tricks I can try ! Thanks

update- i am ready to put this motor back together. i was reading threw my repair manual and it states that you can remove the oil pan on this truck with out removing the engine. an axle will have to be removed to get clearance. so if i can remove the oil pan then why can’t i replace this one piston. any thoughts. the piston and new rings is about $30 dollars. thanks
Watch yourself on the cylinder ridge. You’ll also need to probably enlist a machine shop to press the wrist pin on/off the new piston. If there is no ridge, that’s a good thing. You’ll need to correctly measure the ring gaps, install, etc…

does not seem to be a ridge. i will use a machine shop to set up the new piston if i decide to go this route. thanks
Sure, you can do that as long as you can match the piston and are able to buy rings for one piston. An engine machine shop can handle switching the new piston to the connecting rod.
You will have to hone the cylinder a bit so the rings will seat. Just be sure you keep the crankshaft covered to prevent metal filings from getting all over it.
