honestly dont know...my boss bought it at an auction for like 300 bucks or something...and he dont know nothing about cars so i got stuck fixing it.. Which doesnt bother me really. Anyway...it ran when i first got into it...chain was banging all over the place...pulled the front cover and saw a few chunks of the chain guides laying around in there. So i told the boss man we needed to replace everything, tensioners, chains, guides, the whole works...i didnt want to do it again...he cheaped out on me and wouldnt get the chains. His buddy told him you dont have to replace them. Well whatever i guess...im getting 20 bucks and hour to work on this car so im good with it.
