Infiniti Consumer Affairs - poor experience
#316
Not saying it can't happen, but I checked out the local Nissan dealership, he had 2 Z's that had the problem. Dropped by a tuner shop that specializes in G's, GT-R's, and Z's and he has not had one failure in the past 5 years. He said that his customer's beat the crap out of their cars and not one issue. Many of them in the 100K - 150K mileage range.
It is apparently enough of an issue that at one point Nissan redesigned the gasket. There is a reason they did that.

^I agree with you entirely, I've asked both the Infiniti dealer and the Nissan dealer to provide an estimate. I also will be getting a price from the tuner shop. The tuner shop suggested to install an oil press/temp gauge for POM.
One question, the visual inspection that was done, was it done with a borescope?

This Nissan tech manager called me and said that the 2 Z's that had the timing seal issue were 350's not 370's. He did a global search on engine failures and low oil pressure issues and didn't find any issues with the Z370. He told me to bring the car by and he'll have one of his tech's check the oil pressure, but as far as he's concerned it's a non issue.

I checked the Infiniti IPC and found that prior to 2008 there were no gaskets on the timing cover. In 2008 P/N's 23797EY01A (right) and 23797JA10B (left) were installed. Probably because of issues with oil pressure loss. The same part number is currently being used on new engines. I could not find that there were any prior or subsequent part numbers ever used on our engines. Please advise if this is correct. I don't know what Z forms you are looking at, but no I couldn't find anything on this problem.

I spent the last hour reading all of the posts and now know that the part numbers that I'm referencing are the wrong parts and indeed there is a new gasket. Now that I know the new part number, I can run this by the dealership since he told me that the part number had not changed and if I changed it, it would be the exact same gasket. This really puts me in a quandary. Should I get rid of the car, while it's still together, make the repair, or just hope that I'm among the masses and never see the problem?

Your mind will be much more at ease with the gauge installed. If you get the gaskets, make sure not to pay dealer mark up. They should be roughly $25 for the larger one and I forget how much for the small one. Infiniti wanted $100+ for the larger one at my dealer.

How much do dealers charge for diagnosis and oil pressure check?
And what happens if we do not detect it until the oil pressure ligth comes on?
I am beginning to suspect that my inconsistent mpg (some days getting over 30 some barely exceeding 25, not bad but inconsistent) is maybe a result of oil pressure problems.

With your mpg issue, I would look more at the MAFs,O2 sensors, and cat converters for being your issue. Maybe also gunked up throttle bodies. Are these differences in MPG along the same route and staying same speed and same load? My MPG peaks in 6th gear at about 70 MPH and declines from there. Usually got somewhere around 28-30 highway. Any driving in the city brings it down dramatically.

I can't help you there. I imagine it would be an hour job, so probably around $100, but I have never had it done. Once the light comes on you are already screwed. The threshold for it to illuminate is very low.

My main question was, although I understand that when the light comes on it is already too late but what changes if I detect the problem sooner? When I read the thread I didn't see any posts about preventing this.
It seems to me even if you catch the issue sooner you will still have to pay the same amount for repairs am I wrong?
