I bought this Passat v6 2.8 under the impression that it only needed a starter. The car is in good shape and looked well maintained. Anyway I replaced the starter with the Bosch OEM, but it still wont start. You can hear what sounds like the armature engaging the flywheel and trying to turn and just stop. One time it gave about three cranks and a low pop, more like a poof, then stopped turning. Everything else on the car works fine ( all lights and accessories) I put a charge ( start 125/225amp and trickle) on the battery with same result. I pulled the plugs, all the plugs on the right engine block were ok, but on the left I pulled the middle plug, the entire boot was saturated with oil and the plug was very oily as well. the other two plugs had some oil but not nearly as much as the middle. Also I am hearing a buzzing noise after trying to start that sounds like it is coming from the starter but im not sure. This buzzing does not go away unless you unplug the neg terminal. One more thing that I hope may help, The battery and posiitive battery terminal/wire are getting extremely hot after trying to start 4 or 5 times. is this normal. The battery is new. The car has 157,000 miles.
