Heres the situation, and I couldn't find the answer despite all my searching.
I'm getting a high pitched whine from the engine at all rpms, hot and cold. As far as I can figure out, it's from the very top of the engine, and it's a metallic whine, and not a clilcking or tapping sound. I already checked and lubricated the alternator area. I don't think it's a valve or lifter problem because it's not a pronounced click, tap or ping, but a continous whine.
I'm using 5w-30w oil, and it's topped up. Pulling power etc is as normal. My suspicions were timing chain/tensioner/vanos chain?? (do I have it?) or something of that nature. It started about a week ago, and yes it's cold now, around 5-10 degrees celcius.
Any ideas guys??
Thanks in advance for your responses.
