Minimum is new chain & guide/tightenin bit swap, seals. The chain will stretch when it jumps, dont use old one. Hopefully its only the chain, and not bent valves - I am pessimistic. I suppose that the job price is common at stealership, u should get it half price at another shop. My guess for best case scenario is 4-600$... you'll know as u first ask what timing chain swap costs. You may ask from dealers outside u area for this... The parts u quote may not be enough - what exactly are the part(s)?

Camshaft Chain -3 Nos ( Appx 160$)

Now u have dignosis, you can call shops for quotation, you already have stealership reference. IF Good shop, u get written price, & date when it supposedly ready. ...Try to ask input from friend or anybody for good shops around u, references. The price will vary depending on what is found as engine is opened. Take pessimistic view how much the total will be...

SP== I checked with most of the mechanics here everyone coming with atlest 10 -12hrs labour for 600-800$, TC Parts are not easily available on Advance Auto Parts or Autozone, Those are delaer parts need to be ordered theu NIssan dealer only
Chapest labour I got is appx 550 $ for this job, who gives me gurantee for 90 days for job done when i asked. Which help me to save 300-400$ appx as comapre to Nissan dealer.
What do u think do i really need to change all TC related parts as listed above or just few of them once mechnic will open the Engine??
__________________________________________________ _-
Whatever u do, let the shop u select open the engine first. STOP and no hurry. Negotiate what should be done, what has to, will be replaced, total cost... Write down these details, then ask your regular mech for opinion. Important: youre the bo$$! There is no need for you to know all bits and parts. Take second opinion, maybe have the dissassembled bitts with you in plastic bag... Your reg mech will surely give opinion free, only some leg work for u. But these are taxfee thousands, I do take lots steps for 1000$...
Meanwhile seek in the net for replacement engine (or whole wreck) so u know how much they will cost, might become cheaper? (Japanese law requires them to change engine every 3yrs, and thats why there is big supply of little used engines...)

SP= I checked for replacement engine , nothing much found, my earlier mechanic given me quote for used engine with 56 K milage for appx 2000$ including labour . I dont know how to trust to buy engine from outside when it involves atleast 1000$ labour , withy no gurantee how that engine will work..........

Seek ur guidence again , as i am in delima even though if i spent 1200-1600 $v to fix the Timing Chain problem if it will fix the problem after that if it would have further damage to Engine Valves or Piston Rings...
what are the possibilities of that ???
Please give ur valuable feedback
Thanks again
