Nah!!!! just leave the flywheel on next time you sell a bare block, lesson learnt and all that. :lol:

Technical Bulletin: ACT Flywheel on a Nissan 350Z and Infiniti G35 This entry was posted on June 21, 2013 by advancedclutch. Nissan equips many of its newer vehicles with a dual-mass flywheel to control a portion of the engine’s torsional vibrations, which causes various types of gear rattle noises. A dual-mass flywheel exhibits unique damping characteristics that cannot be replicated with a single-mass design. When converting from the heavy, original dual-mass flywheel to any lighter, single-mass, aftermarket flywheel, much of the original torsional damping is defeated (with a partial exception when also using a spring-centered or damped clutch disc). As can be expected, the result is an increase in gear noise. In general, the lighter the flywheel is, the louder the gear noise will be. During testing, ACT found two types of gear noise that commonly occur when using a lightened flywheel on the 350Z or G35: 1) idle mode rattle (also called neutral rollover noise), which occurs when idling in neutral with the clutch engaged, and 2) burst rattle (or start-up rattle), which is heard when accelerating heavily at very low rpm. Although annoying to some drivers, the additional gear noise should pose no harm to the transmission. ACT manufactures flywheels in both Streetlite and Prolite versions. Each version is manufactured with integral ring gear that allows a greater weight reduction and eliminates the chance of gear breakage. ACT heat treats the entire forging for strength and durability. All ACT flywheels provide safety, improved throttle response, better feedback to the driver and increased acceleration. ACT flywheels are able to be resurfaced, if needed, which can save from having to purchase additional parts, as is common with any two-piece units. ACT flywheels meet SFI Spec. 1.1 and are legal for competition in all racing organizations where SFI certification is required. Installation note: The alignment hole in the flywheel must be lined up with the crankshaft dowel. It is possible for the flywheel to be mounted in a misaligned position. If the alignment hole is not positioned properly, the car will not start or run properly because of incorrect timing of the crankshaft, speed triggers machined into the flywheel.

There is a small pin in the end of the crank which marries up with a small hole in the fly. However it is very easy to fit the fly in the wrong position if you are not informed. Only solution is to pull the box and reposition the fly to the correct position.

There is no crank sensor on the front of the engine. The crank sensor is on the rear of the engine/gearbox bell housing and picks up from the flywheel. I still say that the crank sensor or the fly fitted wrongly is the issue, however you can never legislate for simple silly mechanic mistakes.

I good fitting socket and a bit of controlled leverage is all that you require.

Something hooked up wrong or not hooked up at all. Or lack of fuel perhaps. Flywheel fitted in wrong position and not registering with CPS. etc,etc,etc.

The lifters are not hydraulic, they are mechanical. Oil pump failure, I don't think so. The issue will not be oil pressure related. See my previous post.

If the engine was running okay before, then it has got to be a fitment issue. Sounds like the technician has messed up some where along the line. Pm received and replied to Pedro.

Sorry but that is the best that I can do. Why don't you offer your tray up to the body underside as that will give you an over view of where the bolts go.

...is that the track Zed? Indeed it is the track 350. Retail price of the parts was circa £1000.00 (Genuine Nissan UK )

Just replaced all mine, VQ35DE, 10 years old and only 27,000 miles.

What Brillo has said. hardly rocket science.

Got to be a logical explanation. !!!!! I remember long time ago I got a speeding ticket through the post for exceeding the speed limit some where down south about 400 miles from where I was at the time. The car clocked speeding was a white 4 door Sierra Cosworth. My car at the time was a 3 door black Sierra Cosworth. Both cars were carrying the same number plates which was my own personalised plate. Work that one out. Not Guilty Ma Lord:

There are 3 heat shields. 1 on each cat and 1 above the rear silencer.

So 1 hour then

Battery perhaps as it sounds like you have a CCA issue.
