Chirp, chirp, chirp. Harmonic balancer squealing noise. Could this be the front seal? Having taken off the fan belt, and starting the engine, I get this squealing sound from the front main pulley (harmonic balancer). At this stage this is the only thing turning, Each short squeal equals 1 revolution of the engine. Or could this be something else? Any thoughts? I thank you in advance.

Cam sensor squealing, common.

Any lateral movement in the balancer?

I had this problem about a month ago.

Had to replace the balancer.

V8 or I6? The V8 cam synchronisers do this as mentioned above.

Hi Pridenjoy, You were right, it was the cam sensor. After I read your post I went online and a youtube clip showed me a fix. I needed to take the cap off and squirt about 1cc of engine oil around the rotor and it stopped the squeal immediately. Many thanks for the tip, it was really appreciated.
Kind regards George1957.

Hi undertow, It is V8 5.0 Ltr, and it was the cam sensor. 1cc of oil and problem fixed. It was my cheapest repair ever. Many thanks for your reply, it was much appreciated.

Kindest regards,

Hi russellw, Thank you so much for your reply. It tuned out to be the cam sensor. 1cc of oil around the rotor fixed the squeal instantly. Thanks again.
