Re: engine seized
What do you mean by "seized up?"
A head gasket leak can allow coolant to enter the cylinders preventing the pistons from moving. Remove the coolant (& replace the head gaskets, broken rings, bent valves, etc.) and the LT5 is no longer "seized up." How do I know? :-)

Re: engine seized
MIne hydrolocked after an injector stuck open. Waited for the fuel to bleed past the rings, fired it up and drove it home. That was a bad day...
Until I did a compression test after and found out compression was good. I replaced all the injectors, all is well now. I dodged a bullet that day. I hate that feeling of turning the key and hearing the engine make half a revolution before coming to a complete hault (if you hear the starter motor whine for a second, it ain't the battery going dead!) |

Re: engine seized
Well what i did find was a seized LT5 in florida junk yard, just had it shipped up to MA and it is locked right up, in the process of tearing it down now. I was just curious if anyone has ever had one seize. This engine has around 35k on it but its been sitting in a junk yard in central FL since 1997 after the car was totaled

Re: engine seized
Problem is for an LT5 engine that has set for a long time without preservation being properly looked after is galvantic corrosion sets in between the iron piston rings and the Nikasil plated aluminum cylinder liners. After tearing the engine down you will find clearly defined corrosion etching marks where the piston rings rested on the Nikasil running surface of the liners. If that's the case then the liners,rings, and probably pistons will have to be replaced.
