HI,

here you go

spark plug labor time is 1 hour - $75

spark plugs run $9 ea, so $72

Total parts and labor $147

Valve cover gasket labor time - 2 hours (total for both sides - $150

Valve cover gasket kit - $28

Total parts and labor - $178

Direct fuel induction cleaning service runs right at $150

Timing chain tensioner labor -20.9 hours - $1567.50 NOTE - timing chain has to be removed to replace the tensioner and to remove the chain, the engine has to come out, hence the huge labor hours involved

Grand total - $2642.50

Hi, different expert here. My name is***** timing chain tensioner is only a 2.5 hour labor operation at best. The chain does not need to be removed to replace the chain tensioner. The OEM tensioner retails for $476. Your total chain tenioner job should be in the $750 - $800 range NOT $2642.50. Aside from that, the other estimates are pretty close.
