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 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

Total parts and labor - $2167.50

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.
