The noise is harmless and doesn’t affect engine life just some people find it annoying.
350Z BEST OIL COOLER FREE
If you free rev above 4500, the engine will return to a lower speed more aggressively. What the reflash does is if you free rev between 1500-4500 rpm, the engines ECU will slowly return the engine to idle. Nissan has determined the revving the VQ37VHR without load helps contribute to the noise. Nissan’s TSB for the noise involves switching to the ester super oil and reflashing the engines ECU. The super oil’s attraction to the cam followers helps cushion them hydraulically against the slapping action of the VVEL shoe, thus damping out the noise. Low hydrogen DLC coating is used here to both reduce friction, improve wear in this more difficult to keep lubed interface and to attract the super oil. This wiping action makes it difficult to establish a hydrodynamic film of oil in the interface between the shoe and the cam follower. The VQ37VHR engines VVEL system uses a reciprocating shoe that wipes back and forth across the cam follower instead of rotating like a cam lobe. It has been determined that the noise is caused in part by not using the super oil. More G37 customers complain than 370Z customers probably because the G37 has superior NVH (quietness) to the 370Z and an Infinity customer is pickier. The noise is so slight that it can usually only be noticed when driving with the window open, close to a reflective surface like a hard wall. If a G37 had low quality oil put into it, a customer might notice a very slight ticking noise eminating from the engine later. Naturally this results in the car getting the cheapest possible oil in the changes. Typically these oil changes are a loss leader promotion were the dealerships might actually lose money just to attract customers. As common, particularly in these hard economic times, dealerships sometimes offer promotional oil changes at a very low price to help bring customers in the door. When the engine was first introduced in the G37, there were complaints about a ticking noise coming from the engine, particularly after the first oil change. This leads to the next issue that has arisen with the VQ37VHR.

There is a pic of Keyser's set up on page 1 of this very thread. Have you got anything in your cubby hole? I have a gauge in there, very easy to do and there is plenty of room for two maybe three if needed.
Haven't tracked the car while it's been charged.ĭo you have a link to the way Keyser mounted it? No I haven't got an oil temperature gauge unfortunately! - want to get one, but there's nowhere nice to mount it as I've filled up my pillar pod with AF/R and Boost. Although probably only 50% would be in direct air flow.Īnother option for those with inter-coolers is what Mark suggests of mounting it at an angle behind the crash bar and deflecting the air towards it Regarding mounting I'm in the same boat, but if you see how Keyser has mounted his I think that'll give just enough cooling even with the oem or nismo bumber.
Have you tracked your car? Do you have a oil temp gauge?
