Hey guys
So i bought a 2007 Subaru impreza wrx 2.5 hatchback from an auction with no key. i got the key sorted and when i started it i heard a knocking from the engine and it was smokey. there was no misfiring from the engine just knocking. i have a feeling it is from the crank but not 100% sure.
Has anyone had this issue before? Im wondering what is the best solution for this? change the engine or get it rebuilt?
any suggestions?
