cannot find anyone who has replaced a timing chain on a 2014 nissan altama 2.5 (qr25de) engine. The manual says to remove engine and trans assembly, then separate trans and put engine on engine stand. Is all this necessary? i have done evaluations and the only thing i can see that would hinder me would be having to hold engine up with a holding device during repair. engine is doing weird timing symptoms that were almost unexplained until i performed the cam/crank correlation test on a scope meter, and have found with this test timing is off at least a tooth. At this point I know there IS a timing issue, but need to break down to see what and why. (94,000 miles with a good history of maintenance) tomorrow i plan to explore this issue with engine in vehicle but while i was thinking on it wanted to see if you have had any experience with this. (nissan dealer and identifix fellas have not done this repair they say). PS if you or anyone does have experience in this procedure any advise would be much appreciated. .. PS all solenoids and vvt sprockets ARE working properly(as far as tests go). Thank you
