The engine is in the car, and is sealed. Four Questions... 1. What size is the front crankshaft bolt of a Fiero V6? 1a. How much torque do you have to put on it to get it moving. 2. If the engine hasn't been running in 6 years (The car/engine spent 5 years inside, 1 year out) could turning the engine slightly over do any damage? Not even a full rotation, I just want to see if it's seized. 3. If it does turn over, would you recommend that I start it without tearing it apart? 4. If it doesn't turn over, what is an estimated cost for rebuilding it? ------------- I wanna go fast. |

19mm if memory serves. With the plugs in, could be anywhere from 20-50 ft-lbs If you can rotate it 720* with nothing going "clank/bang/etc" then just check all fluids and filters (might want to change both!) then just light it up and look for leaks. If it IS seized? Just find another one unless you need a numbers match. It's about 2-3K for a rebuild. |

I say don't even bother with the hand crank. Unless it does not have a starter.
You can pull the coil wire and both the plugs going to the ignition module. (I remove the module wires just for the slight chance that the cranking will power up the module and damage pickup coil) Check all the fluids, and hit the key, if it rotates without any bangs, hook up the ignition and light the fire so to speak. If its been sitting that long, before you put it into extended use, it will need a full tune up and oil change. Oh pop the air filter out. In most cases it will be rusty and you don't want chunks flying into the intake. ------------- Capt Fiero 88 Fiero GT 5spd V6 Eight Fifty Seven GT V8 5spd. |

 I think I'd be nervous that something might get damaged. Even if it isn't seized and does turn over there could be a ridge on the cylinder wall where the piston sat. I would think turning it over that fast could probably do some damage. Where as in a hand crank you can feel if something is binding. ------------- I wanna go fast. |
