My 2008 HR has only 26k miles on it but hot idle Is around 15psi according to the gauge. Might as well think about replacing gaskets. But here is estimate I got. Why all the other parts besides the gasket are those truly needed ? I was told all I need are gasket themselves
Parts $10.00 (Sealant / Gasket Maker)
Parts $37.50 (Full Synthetic Engine Oil)
Coolant $35.00
Shipping $TBD
Labor $1150.00 (Discounted from $1314.00)
TOTAL ESTIMATE W/ TAX: $2,164.52
UPDATE : He said timing belts and water pump ($700) are recommended since they will be in there and I already paid for labor. But why do they need to be replaced at all?
15 psi seems to be normal at idle after being warmed up. Put an actual gauge on there and see what the actual oil pressure is before throwing money into it. Is the car acting weird? What shop did you take it too?

No car is perfectly fine. But I keep getting told I'll have to do it guaranteed at some point so might as well do it
I second bre's suggestion. With 5W-30, at idle speed & oil fully warmed up, 14-15psi is considered normal. At 2k rpm, it should be around 43psi (again, at operating temp).
Note: I pulled these stats from my FSM, granted it's for a DE, but I would imagine the HR is basically the same.
If that mileage on your Z is accurate, then you don't *need* to replace the timing set or waterpump. But the shop is correct, to replace those gaskets, you're basically paying for the same labor to do a timing job, so it's one of those "may as well" things, but again, the mileage is low so it's something I would consider optional based on funds. If the shop gets things taken apart and discovers some unusual wear on the chain guides or chains themselves, then it would be worth having the parts handy and just knocking it out then and there. More often labor outweighs the cost of parts and it sucks to pay for it twice!
Ultimately your call. If it was my Z, I would do it for peace of mind, at least the waterpump because rubber seals also die from age, not just mileage.
Cheers!

Thanks man!! Yeah the guy stressed the age of rhe car rather than the mileage which is low!
I wonfer if i can order the parts so they have it but then return them if they get in there and find out it's fine
I was thinking along the same lines. Usually you can return parts if the packaging is left unopened. But make sure to check with the parts seller about their return policy before pulling the trigger. Also, how much do you trust this shop? Are they reputable? You have a super clean Z and I would be worried about the shop breaking or damaging things while conducting the engine surgery. I could be wrong, but I believe the entire front end needs to be removed/dismantled to do this job. I would be concerned with scratches being put into the bumper/headlights and breaking harness clips and such. The labor cost is low IMO, which means they may rush through the work.
When the time comes, I plan to do the timing set and waterpump on my Z myself. At least then, if there's a screw-up, I only have myself to blame, which I can live with. I've been burned so many times by shops fixing one thing, but breaking or damaging other stuff in the process and trying to hide or ignore it. Some shops own up to their mistakes and try to make it right, others basically say "sorry, not sorry." Either way, time & money is lost fixing someone else's mistakes.

Ive used then to change the differential bushing but thsts kind of a small Job .
Damn now I'm really thinking about it. It's a decent shop but pretty messy
Do the gallery gaskets if/when ever needed. Don't open a can of worms where unnecessary. Doesn't sound like you're exhibiting any of the typical gallery related issues like low pressure, leakage, fluctuating pressure beyond what's normal. While the HR/VHRs engines are more PRONE to needing them swapped, keep up with regular maintenance, good synth at regular intervals, etc and you're good. I mean, doing it now is like, dropping the trans, swapping out the CSC just because the HR/VHR units are known to "always fail". That's something far more common than gallery gaskets.
In the meantime, I'd be more wary of the water pump being 20 years old but, be that it's not exposed to open air, more than likely fine. Doing gallery gaskets isn't preventative of anything.at this mileage but if it sat for a while (must have), I'd do the serp belt, WP and coolant if you absolutely need to spend your money on something. That's PM.

Thanks man. I keep getting so many conflcting opinions on this. Like on the 350z Facebook pages I follow, everyone harps on and on and on about the gallery gaskets and they seem to have "might as well do it now and get it over with before it happens"
I'll hold off. Honestly even though I got the car for a very reasonable cost given its excellent condition, I still had to pay $600 to replace the diff bushings, and $900 delivery. I also replaced the intakes with Injen. I spent enough as it is
Then just got fed up with all the misinformation and blind leading the blind with that information. Dropped following. Not a blanket condemnation by any stretch but the experience and knowledge in real life and to a high degree here and 350Z Tech, NICO, is leaps and bounds better and more accurate.

In your opinion, is gasket failure guaranteed to happen to an HR at some point ? Is there an average mileage when it does and what are the clear obvious signs ?

Nothing is guaranteed to happen. Yes history has shown that HR gallery gaskets are prone to failure but doesnt necessarily mean it will happen . Same goes for the early DE manual transmission. Youll read about how they have bad synchros and go bad which will need a replacement or upgrade to a CD9 but theres plenty of members still with their stock DE transmissions going strong with no issues... including myself. Never had any issues with my transmission.
Theres a lot of factors here. How much the vehicle is used and how its used. Whats the maintenance like and so on. Dont beat yourself up on this. If your Z is running great and not showing any signs of issues just keep up with the maintenance and drive it. Now if money isnt an issue for you then go ahead and change all those parts out.

Thanks man. Finally a voice of reason. It did sound weird to me to worry about something that may or may not happen
I agree with Mic an Bre. Take with a grain of salt, but I don't think you need to make preparations for the maintenance until you're closer to 100k. The good news is you are aware of the problem and thus can catch it should a failure occur. Here's what ChatGPT says.
Cheers!

I really appreciate this post. I've had my HR Z going on 13 years and never heard of gallery gaskets until I joined Reddit last year. Everytime someone would post on Reddit mentioning interest in a 07 or 08, the majority of replies seem to be concerning whether the car has had gallery gaskets done. There were a lot of other bad recommendations in that forum too, but the constant talk of gallery gaskets had me pretty concerned. I am no longer on Reddit and will stop worrying about the gallery gaskets unless I have symptoms. Thank you to the OP and everyone who replied with common sense answers.
