Hey brother thank you for the information,I have a question how did you get the oil jets out.or were did you get the tool from.

[@DallasAutoDiag]

I bought the tool from the dealer at that time

[@nikolaypetrovich7624]

thank you for posting, do you have any of these parts numbers that you recommend to do along with the time chain job?

[@DallasAutoDiag]

Sorry it's been a long time and I don't have the part numbers anymore. Your mechanic should be able to tell you what to change. And you Can go to the dealer and they give you the part numbers.

[@amandabarrera3784]

Has it been running good with no issues since? Have you experienced a whining noise from the engine?

[@DallasAutoDiag]

It has been running well since.

Hello, do you think the timing chain issue, could have caused the catalytic converters to fail? thank you.

[@DallasAutoDiag]

timing issue could cause a misfire. a misfire could cause a failed catalytic converter. so the answer is yes

[@RAf12580]

@@DallasAutoDiag thank you for your response. I just had the catalytic converter replaced on the driver side bank one. I still have codes PO 300 and code P0307. Which are multiple misfire detected and misfire on cylinder seven. I am going to change all of the spark plugs, and I will be changing the ignition coil on cylinder seven. I am hoping that this will help. I will be doing the timing chain soon in order to prevent more of this. Have you heard about qx56 issue the metal bucket on the high-pressure fuel pump? Thank you

@@RAf12580 never heard of it.

I have a problem in my Nissan Patrol 2012 same engine. Idling RPM is higher than normal with ups and downs and the exaust air is not smooth. I can feel it in by hand fluctuating. This happened after replacing valve cover gasket had to remove all ECU connections. I also replaced three ignition coil boots which were stuck and melted inside due to overheating issues before. I got no check engine but when I run OPDII check I found that air fuel mix value alternating between LEAN and RECH for both sensors. What can be the issue. I'm going to replace the spark plugs but I need to know if anything else needed to solve the issue.

Have you tried idle relearn yet?

[@MkB-1989]

@@jacobrutherford9132 I tried it but no use.

[@jacobrutherford9132]

@@MkB-1989 sounds like you may have a vaccum leak. Best way to find is do a smoke test to see where the leak is at. You can spray brake clean around it and if the idle changes you know you have a leak in that area. Be careful with the break clean when doing it.

[@MkB-1989]

@@jacobrutherford9132 Solved it finally. I wasn't suspecting air leak as much as ignition coils because the fluctuations is not continuous. I found one of igintion coil leaking from the joint between rubber boot and plastic cover. Tabed it temporary to check and it did solved it. I will try to get new coil boot because it's hard to find. Thanks for the assist.👍
