ENGINE Rebuild, P0011, P0021 Help!

laytonanthony · 07-02-2015, 06:22 PM

Hi guys
I own 2 nissan 370z's. A coupe and a vert. My coupe got starved of oil and I had to have the engine rebuilt. The engine builders replaced all bearings, piston rings and a new crank.
We have fitted the engine and struggled to get it to start to then realise the vvel sensors were not set. I set these with consult 3 to 0.500v. With a bit of peddle then the engine fired and bedded all the piston rings in ect. The car will idle fine but has no throttle response and when given some gas will seem to miss. Also car will not go over 3500rpm (limp mode). Consult 3 gave 2 codes, P0011, P0021. INT/V TIM B1, INV/T TIM B2.
i have checked the timing solenoid and cam sensors. All fine. My engine builders is 100% confident it's timed properly. I know these engines rely on oil pressure.
Any suggestions would be greatfull. I'm at my last tether with it!

Ant.

A log would be nice, but without its hard to diagnose. Its like shooting in to a barrel with 1 fish while blind folded.

Sounds like the codes I threw after 2 of my internal gaskets blew..

Blighter · 07-04-2015, 12:17 AM

how much was an engine rebuild? Is it that much cheaper than just putting a new/used motor from another wrecked z? JW why you went with the a rebuild rather than a transplant...

laytonanthony · 07-04-2015, 04:10 AM

Here in the UK engines are hard to come by. Talking 5k!! Engine rebuild was 2.5k! My engine had only done 30k.
Are the internal gaskets the 2 paper gaskets which blow oil into the timing case allow oil pressure to drop? Where can I get these?
Thanks for all your help and advice

Have a look at this thread -- I bet its the same problem.

Cause for the dreaded P0011/P0021 codes that everyone is curious about - G35Driver

laytonanthony · 07-04-2015, 01:58 PM

Had a look but that's for the vq35vhr engine. Is it the same gaskets on the vq37vhr engine? I can't find anything else related to that for the 370z.
Thanks for your help. Hopefully this is the problem

NeverBoneStck · 07-04-2015, 02:02 PM

There is on myg37.com. Your gaskets failed!!

laytonanthony · 07-04-2015, 02:10 PM

Ok
I'll tear down front end of the car tomorrow and inspect. I'll report back with pics tomorrow.
Again thanks for your help.

Really man? Guys looking for advise for a problem.

laytonanthony · 07-06-2015, 04:24 PM

Im now stumped!

With Service Manuals diagrams, components, TSBs, and R&R procedures

Number: 548509
Vehicle Application:
2008 G37 3.7
Customer Concern: Malfunction Indicator Light (MIL) is on. Bank 1 Intake Valve Timing (IVT) control code P0011. Has a low power complaint. The engine will not rev higher than 2400 RPM. Scan data shows the bank 1 IVT at -14 degrees and the bank 2 IVT at 0 degrees at idle. Can manually operate the IVT control solenoids on each bank and get the engine speed to drop the engine to run rough.
Average Reported Mileage: 50000
Tests/Procedures: 1. Scope the Camshaft Position (CMP) sensors and the Crankshaft Position (CKP) sensor and check for good square wave signals and check the phasing (sync) of the signals.

2. Remove the bank 1 intake valve timing cover from the front of the timing chain cover and use a 3 mm allen wrench in the front holes in the center of the bank 1 intake camshaft sprocket - it should only go in about 3/8 inch. The back holes should allow the allen wrench to go in over 3/4 inch.

3. If the front holes only let the allen go in 3/8 inch, then the intake camshaft sprocket is at 0 degrees. So then either the timing chain is off, or the camshaft sensor reluctor fingers on the front of the camshaft sprocket may have turned on the sprocket.

4. Can see if the reluctor will turn on the front of the intake camshaft sprocket. See related document for position of the reluctor fingers on the front of the camshaft sprocket.
Tech Tips: We have been seeing cases of the reluctor fingers for the CMP sensor, turning on the intake camshaft sprockets. The reluctor fingers are press fit onto the front of the sprockets. The related document shows the known good (new sprocket) CMP sensor reluctor position on the intake camshaft sprocket, along with one where the reluctor had turned on the sprocket. See if the reluctor is loose and if you are able to turn it, and also if it is in the correct position. The photo is from a 2012 but both are 3.7 Nissan engines so I would expect them to be the same. The pictures are not straight on but hopefully they will give you an idea if that is the issue with the vehicle you are working on.

Its most likely timing related, hope this helps! ^

PM me, ill send you some more info off identifix, theres some other comfirmed fixes aswell.

I have a feeling its related to your timing, The sprocket/chain might have been installed wrong,

Theres also 100+ comfirmed fixes by changing the oil filter, I doubt its that but worth a try.

It plugs up, causing lower than normal oil pressure. But oil light will not come on!
