Yeah we see these codes all the time on the V35 models normally with the higher mileage which is normally a low oil level issue. The I35's and QX4 models are the worst for these codes. You are definitely not the only one for sure.

 

Now the P0014 and P0024 are exhaust valve timing codes. These codes normally pop up due to the exhaust retarders going bad. Those are the 2 big caps so to speak on the front timing cover with the sensors in them. There is an electromagnetic clutch on the back of this that works with the exhaust cam sprocket and we do replace these on a sort of regular basis also. Parts are a little costly, but not as labor intensive as the rear timing cover gaskets. Once they are replaced, A Consult 3 scanner will need to be hooked up and an exhaust valve timing relearn procedure will need to be performed which has to be done with the car running at 3k rpms. Hope this provides a little more insight to these crazy codes.

 

Thanks for the info. The Nissan dealer (I will not have it fixed there, have a local mechanic) recommended replacing the rear timing cover. Would that have anything at all to do with the P0024 code?

 

Not at all, the rear timing cover repair is for intake valve timing codes only. You have an exhaust valve timing code which should be the bank 2 exhaust retarder. This part can actually be changed in about 30 minutes, but the relearn procedure that I told you about will still need to be performed after the repairs.

 

Sounds great. Any chance you have a link of where to purchase that exhaust retarder? My mechanic is very small town, and I guarantee won't have the part on hand. If I bring it to him, however, he will probably swap it out while I wait.

I appreciate the info and advice. I can change out sensors and do regular maintenance, but I'm pretty lost on engine repair.

 

I do not have a link right off hand but I do have the part numbers for the exhaust retarder that you need. 13040-JK22B (B2 exhaust retarder assy.$569.50) and the gasket part number is 23797-JA10B(retarder gasket $3.87) The gaskets for the P0011/P0021 codes unfortunately are not available to buy individually. You will have to purchase the entire rear cover in order to get these gaskets at this time.

 

I figured the part would be rather expensive, but it's nice to know the install is not that labor intensive. You thought that a mechanic could have this done in half an hour? And then of course would have to do the relearn you mentioned as well. Thanks again.

 

Yes absolutely maybe 30 minutes. It is very easy to replace.Good luck with everything.

 

The SES light magically disappeared today. Is it common for the P0024 to come and go, or is this unusual?

 

omg thank you haha, I been dealing with the P0011 code forever. Do you know if it harms the engine if I don't replace it? Because I been driving for around 5 month and it hasn't came back, I just avoid driving at 1.9k-2k revvs cause it seems like that's when it occurs.

 

I've only heard one of the V36 models come in and had a rattle on the top end like it was completely starved for oil. I guess it just depends on how bad the gaskets are blown out

 

We have always replaced the cover gaskets when this happens so I'm not 100% sure on that. Most of the one's that we've done have been under warranty st the time.
.

 

So I talked with a infiniti Mechanic and you can get just the gasket. The parts number for the gasket is either 13530-JK20B or 13533-JK21A. Not sure which one is which because I asked him for the parts number for the gasket and the rear cover. I'll keep it posted I just sent him another email asking which one is which.

 

13530-JK20B is a cover

13533-JK21A is a gasket

 

Oh haha cool. Thanks! he just replied to me and said both are gaskets hahaha 0.0
