l have an infiniti g35 and my engine has locked up. From lack of oil. How much will it cost to unlock engine and is it actually worth the cost.

go to a salvage yard and get a used engine :)

try to get it overhauled. should cost bout 300-400 dollars. still better than getting a used engine..

when an engine gets locked due to oil starvation that means that engine is gone (and needs an overhaul) you can either get a used one l will cost you about 400-500 dls or get it overhaul (no it wo not cost you 500 dls as criket b said l wish an overhaul were that cheap) overhauls run from 1000 dls and up (i know about cars and engines) good luck

You have over rev your engine
