You can try clearing the codes while running, if you hear a change in how it runs then you know the computer is trying to protect the motor. If no change then I think your timing jumped pretty far out causing all of your issues, I probably wouldn’t drive it anymore or you can run the risk of hitting a piston into a valve and then your really screwed!

Yes I was a bit worried about that last night. Started up this morning and was fine. Ran an errand at lunch and had full power cold so... weird issues. Anyway thanks for the tips and following up on your issue.

Curious, have you removed the vvt solenoids to inspect and if possible apply 12vdc quickly to them to see if they’re working? I’ve read that a failed solenoid caused somebody misfire codes as well.
Update: Also, I received some parts, just waiting on 1 intake sprocket and some gaskets.

I haven't yet. good suggestion though. I will try that when I have it apart. I know the TChain components need replacement based on the noise and where it's coming from but that solenoid issue could be one of the contributing factors to what I'm experiencing. I'm going to replace sparkplugs as well while i have the intake off given it's at 168000km. I ended up ordering from the local dealership and got a bit of a deal since I used to work there so it worked out to be a bit less than what I saw in the link you sent. Hoping to receive tomorrow and go at it this weekend.

How are you making out? Were you able to start it last weekend? I just started today and I’m relieved right now because I was able to get the 4 cam sprocket bolts loose! Didn’t even have to remove the valve covers, impact fit on 3 of them, and for the back exhaust sprocket closest to the firewall I was able to use a chain vice grip and a 1/2” breaker bar. Will hopefully be done with this Thursday so I’ll update the forum!

Awesome! Yea i started on the weekend but struggled 4hrs getting the crank bolt out. Had to go buy 3/4" x 30" breaker bar and thankfully i had an old drive belt kicking around to hold the crank. Took 5 minutes with the 3/4 bar sheesh. Anyway now trying to seperate the oil pan without wrecking it. Any tips? It's glued on hard. I see there's a special tool that gets in there. Anyway i should have it done today. I've got the day to work on it.

Niceee yea I had to go out and buy an impact gun and the bolt came off pretty easily! The oil pan I had to use a super skinny flat head and hammer it in until it started to seperate. I worked my way around and it eventually spread enough to stick a bigger flat head inside. Hope that helps!

Thanks yea I'm starting with a metal putty knife and will work my way up. Going to apply some heat to see if that helps at least make it more pliable. Cheers

Dear god do I hate putting the timing cover back on. Plenty of room but the hardest part is getting that gasket to the upper oil pan to go in correct is the biggest PIA. I will be finishing tomorrow, just have to re-install everything else and then start it up!

 

[Streetstyle54]

Finished the job today. No check engine light yet. I’m saying yet because it was taking a while to come on previously 😂 I held the gas pedal and brake and started it up 4 times to get the oil flowing. She started right up, performed the intake control relearn and test drove it. She runs smooth and I’m seeing an increase in gas mpg which may be a good sign? Only time will tell and maybe I’ll be able to get the inspection done, that was due since July 😅 no oil leaks this time.

Exhaust cams are running at 0 degrees at idle and intakes are at -1.0 and -1.5. Prayers I got it this time!

Oh, and this was my THIRD and LAST time I will be opening that timing cover no matter what haha

I'm still apart, finally got everything off to get the chain out, and starting to put everything back together. Not looking forward to putting the cover back in, will definitely be a pain. So many dumb little clips and brackets all over just so time consuming anyway we'll see how it goes. I haven't been able to get a specific procedure for the vq35dd and going off the de which is a bit different. I didn't see a mark on the oil pump to match the crank sprocket key to, but relatively sane position (about 11 oclock) with the cam marks at 10 and 2 oclock respectively (as mentioned in anything I've found on the DE). Wishing you luck that your light stays off!

I sent you the timing cover and timing chain guides from Nissan, hopefully the pictures aren’t confusing! Oil pump doesn’t have any notches that need to be lined up. Your engine is so clean! I appreciate the pics and I know exactly how you’re feeling!

 

[PoManzPathy]

Awesome pics!

Seeing these makes me want to never buy another chain drive DOHC V6 again. All those plastic guides and tensioners... If you're not able to fix them yourself, it would be a search to find someone to even want to do the job for you for a price that didn't exceed the value of the vehicle.

So I’m getting her inspected tomorrow I can’t believe it!! It’s been so long since I’ve seen 8 monitors ready. Will update tomorrow as long as everything goes good!

Here i am, chains on, rotated a few times to ensure no valves meeting pistons. Cleaning up cover to reinstall tomorrow morning.

You did good.

Going forward with this, what's your plan in terms of the oil you are going to use and interval to change it?

Looks good man! I also have successfully passed inspection. Do a couple of dry runs getting the timing cover in so you can see what you might hit. That’s probably the smartest thing I did haha it went back in without touching a thing!

I’m going to be trading it in at the dealer that sold it to me. But going forward I’ll be doing oil changes no more then 5,000 mile intervals on the next one! I usually use Mobil 1.

Yup did that haha but still not great. Got it on though so making progress. Now if i can figure out how to replace these oil seals as instructed without them breaking (unless they are supposed to be split) I'd be happy.

*edit, looks like they are supposed to be split.
