what are some signs

When I stary my car in the morning around 6 a.m. after it's been sitting for about 12 hours it runs like crap.

Like someone dumped concrete into the engine just does not want make any revolutions

Then sometimes I hear this Metallic clanging (high pitch) comng from the belt/pulley area {It comes and goes}

I think it may be bad pulley [ Bearings ] wheels.



what you guys think?
