So far they had it checked out electricaly on Monday and it checked OK. Tuesday they had a down day because of a prior, more pressing truck they had been waiting for parts to.

Today I guess they took the valve covers off.

Cam's look good, phasers look lined up. No scarring, chaffing or whatever on the heads. Said there is NO indication maintance or abuse is an issue. Service writer said "Heads don't lie"

They did find they have a loss of oil pressure somewhere, they are going to try and pinpoint tomorrow. Said the noise I heard was metal on metal from lack of lubrication due to a failure somewhere. Looking at the oil pump I guess tomorrow. Service writer said it could be it failed/failing causing the low oil pressure. Funny thing is I NEVER got an idiot light and it always checked "OK" when I ran the onboard status check thing.

Said worst case scenario is a new engine, that was what they had to do last time she saw a similar situation. Best case scenario is oil pump and replace any associated parts.

Either way it is me and the Chevy Impala for at least a few more days.

Said she had every indication based on what she saw and has been told that this will be a warranty issue.
