Nissan maxima does have a chain and if the cover has broken it will be an expensive repair
items of concern are the chain, the cover, the sprockets for the cams and crank, the adjuster and the guide and valves ( it is not listed as an intereference engine but prudence suggests to expect bent valves)
I seriously suggest that you by pass the local garage and seek assistance form an accredited service shop that has experience in your make of vehicle as it is not a simple change the chain job.
get quotes first as the expenses can be double because of the extra damage incurred
not true.
SOHC 4.0 tensioner and rails fall apart, allowing the chain to
slap and do damage, or even break.
book it.
in order to replace rioght side cam chain and tensioner, the
engine MUST BE REMOVED!
if it has balance shaft chain in oil pan, there are a total of four chains in this engine.
dealing with timing chains its harder then timing belts i mean if you have the right tools it can be done but it can be pretty difficult when dealing with the timing , and the chance of a bent valves it depends if you have a 2.0L DOHC there is definatelly a pretty good chance that u might have valve or piston damage, if you have 2.0 SOHC u wont have damage at all
If the chain broke at highway speed then you have probably bent valves too. Does the motor spin fast? If it sounds different cranking then it may have bent valves. You can do a compression test to find out for sure. Good Luck
Not good. I would expect the garage to foot this expence as Im sure your initial bill was far from a cheep one? If a customer of mine had suffered a similar issue, I would certainly work very closely with them to rectify the problem. There is of course a slim chance a catastrophic component failure has genuinely occured, which may be completely unrelated. However it is most unlikely this time, as when your timing chain failed the valve to piston collision/impact would have caused serious potential damage to the crankshaft and big end bearings. This symptom is not overly common in most engines where timing chain/belt failure occurs. However, all engines are different and may experience different levels of damage. A replacement engine does now seem the cheepest way forward in your situation. Perhaps the garage should source one and you might pay for the fitting only? Good luck
