Replacing the gallery gaskets next week, question about timing components to replace

JARblue

When I did that work, I also did the thermostat Didn't bother with the timing chain. But I did throw in some SuckerPunch oil pump gears

I would take a bit more time and plan this one out a bit more.

Financially you can find a newer VHR and depending on the shop it might be easier for them and maybe more cost effective on your end.

You can save the old engine and sell it or practice with it.
The newer VHR will have newer pumps, updated seals, less blow-by, etc.

Otherwise from experience of having to take off the rear timing cover, you might want to prepare yourself for any unseen expenses.
Your cam guides will probably be a bit chewed.
Water pump is necessary, might as well a Tstat.
Coolant transfer tube gaskets in case the tech pulls the whole tube while pulling the neck, very likely re-using the gasket will fool you into thinking its not pinched)
I went and got a tube of Nissan sealant as well (you'll need some good sealant for the cover)
Hopefully no VTC issues or slipped phasers.

There is quite a bit of math to do. If a new motor will be closer to the budget for the gallery service, I'd say go with the new motor.

lol that sounds like a dealer answer if I ever heard one. Even with $1K in oil pump gears, the work I did under the timing cover doesn't even come close to the cost of replacing the motor.

Depends, are you doing any other gaskets like I stated earlier?
Unless he pulls the VTC cover these is no way to determine the condition of this engine internally. I was at 136k with some crappy service it's entire life.
Many things were replaced and that was doing the work myself.

20k miles later no issues but I wish I would have gone with a newer engine, I would have had an extra as a donor plus it is extra parts that I can store/clean/mod/paint.

You can literally sell 10 parts of a VHR and make the labor back. Might be too much for the OP but it's all dwindling on what is found upon disassembly.
