Heard a knocking noise I feared was rodknock. Took it to the mechanic and they spent an hour looking at it and said the timing chain is loose and the guide is broken and separated from the bracket.
Quoted me around $1,000~. $600 parts. $500 labor. Not guaranteed this is the cause of the sound.
Car itself is only valued around $2k.
Is it worth it? I don't really have money for a new car, but there's no guarantee this one won't continue to have more issues after this fix either.
Is $1k reasonable?
Is it something I, with no garage and limited mechanical experience, could replace myself?
Should I call back and ask them to check the oil/filter for metal shavings to try to further rule out a messed up rod/bearing in the engine?
