[QUOTE="Richard L, post: 1017385, member: 52972"] I agree with l1tech. If a dual overhead cam "V" motor has low compression on one side only, I would look at cam timing.. Probably a timing chain issue. Early Gen1 V6's were known to have timing chain issues...mostly noise caused by timing chain tensioners, however once the change gets too much slack, it's prone to chain and sprocket wear which can cause the chain to skip a tooth and throw off cam/valve. ...Richard [/QUOTE]
