THE BULL

As surprising as it sounds, that is all that it takes to overheat the oil, even great oil would have you around the same temperatures. This is a manufacturer defect but one that with the proper research can be mended. You'll notice the difference right away with that cooler.

If you want to prepare for the gallery gasket, install an oil pressure gauge. You can have it visible or hidden. At that mileage it shouldn't need constant attention and if a worry ever rises you can compare your pressure numbers to the ones here which are pretty constant.

FYI I saw the repair order of a 2018 that had a full top replacement under warranty. $19,000 for a brand new "Nissan" top.

Safe to assume that a convertible top tech will have business for centuries
There is a guy in the G37 forums called Guy Menard that makes billet gears for the G37 top. Unsure if the Z has gears like the G but if they do then these gears are PLASTIC.

Start putting somethings on paper to set aside a budget for the car to take care of these pesky issues and it will last you a lifetime. No kidding.

The Fast Intentions cooler kit is a nice setup. Concern about oil temps have been eliminated for me.

Can you summarize the gallery gasket thing?

I take it the gallery gasket is a point of common failure that cause loss of oil pressure and perhaps engine failure and one must pull the entire motor to replace it? Does it fail w/o warning? Are you advising I get and oil pressure gauge engage before I proceed further? Or only if I am keeping the car long term?

$13,000 for the parts and $6000 for installation for another top that will most like fail in very short order.
If corporations actually had consciences, Nissan should be ashamed.

Thanks. I have plenty saved to handle this, and future problems (in fact I could, and in hind sight probably should, have spent a fair bit more for a vehicle for this trip) with the car, but the plan, as it always has been, is to sell the car after the trip. I love having a roadster, but don't have the space to garage it and it's just not practical for me as a daily driver.

That said, it is not my intention to knowingly ignore any maintenance issues in hopes of perfidiously passing them on to some future unsuspecting buyer. The car is now in significantly better shape than when I purchased it and, except for the added miles, I'd like to keep it in excellent condition.

The gallery gasket doesn't require engine removal, just almost everything on the front of the engine to get to them. There is a kit that has all the replacement gaskets and fasteners. You'll want to use loc-tite and a punch to stake the fasteners in place to keep them from rotating out. Sorry to hear you had such a piss-poor introduction to the car.

Galley gaskets are inside the timing cover. Your year has chitty paper gaskets that are guaranteed to fail eventually. When that happens your oil pools in the timing cover and your pressure drops. By the time the OEM oil pressure warning light goes on, the motor is already toast.

Replacing it depends on your skill level / tool quantity. When I did it, I had very little of either and it took me a month of after-work nights and weekends. Nowadays it would probably take me 10-16 hours, alone.
