Noticed some intermittent squealing/squeaking over the last couple coming from the engine. Thought it might be a bearing on one of the front pulleys however it sounded very fluid in nature and would have pop/cracks associated with it at times. Was trying to get some video to identify it but was never able to catch it. Anyway, started the truck this morning and is smoking pretty bad now. Has never had this much smoke on startup before. Has not been stored long in fact was running just yesterday. Looks more white than blue. Anyone have any ideas as to what might be the cause? Or how to identify the cause? Would a blown head gasket look like this? I’m afraid some debris might have broken loose in the cooling system and that squealing/cracking was chunks floating around. Thank you all in advance.
