So i recently bought another a4 from a kid eho haf no idea what the hell he was doing. Price wad 300 bucks😎. Has forge rec.valec, ecs boost gauge, cts fmic, ko4, and afe intake, stock injectors, atp exhaust mani, no tune. Now to the point. He sold the car because of a no start issue. Well he said he rebuilt the. When I got the car towed home. I found that the cams timing was of , the turbo was held on by one bolt with no gasket( huge *** leak). Anyways i rest the cams and boom fired right up. Happy.... Not quite. I suspect the cam shain tensioner is faulty. Little noisy. Now heres my question. Im not sure the cams are dead on. This head has no alignment marks on the caps. The exhaust cam has no alignment mark as well. This head also has no head code i.e aeb. Its just blank. I have no clue what head this is. What head should be on this car? Aeb like my other a4?
