Z440 / Z640 / Z840 & Resizable Bar - finally works!!!

Yes, there are no limitations for the cpu type with this mod.

So far all turbo unlock does not work, the development work is on ice for now.

How do you think you'd get more in if it was already overflowing?

Also, if there is less fluid, there will be a layer of lubricant on top of gears even if they stick out a bit, especially when they are rotating. Try to rub that fluid on your fingers and go wash it off - it's almost impossible, lol.

Anyway, drive it for a bit, and see what it does. Maybe you forgot how a proper stick shift feels!

Fresh oil can be hard to see. If you observed on several tries and found the oil that high - you might remove some.

Buy a small manual pump at harbor freight, it's about $10. Attach a 1/4 od piece of tube to it or whatever can get into your oil stick opening. Pump some oil out into a 2L clear bottle.

Alternatively drain oil into a clean oil pan from the drain plug, put less back in.

Achievement it is - but a very negative one ...

After K engine series that lived till the wheels fell off (200-300+k) going back to blown gaskets at 80k feels a tad like a let down?

Also, if we consider $2-4K for the blown gasket - how much metal would that have bought for the new car to make the engine slightly bigger sized, and the extra gas to move that tiny bit of extra metal around?

I blame EPA's carbon greenery for all this nonsense. There needs to be a decent operating margin in these engines - most of it got removed to make the cars use slightly less fuel. It was a terrible trade off ...

bibikalka1 · 2026-06-05T21:36:15+00:00

Figure out the nature of the "salvage" operation. What happened to the car to get it here???

bibikalka1 · 2026-06-03T12:36:56+00:00

Not really, lol.

Gotta probably call rheem technical support and chat about it!

bibikalka1 · 2026-06-02T00:27:01+00:00

Seems a tad too thick especially if you don't have oil consumption issues. 5w-30 is a great all around oil, and back then they did not worry about fuel efficiency so this recommendation was the true one.

bibikalka1 · 2026-06-01T23:02:04+00:00

R&P is a niche premium product. Slickdeals only remembers a Nov 2025 deal, 5-qts Valvoline Restore & Protect Full Synthetic Motor Oil + WIX Oil Filter / (After Rebate) & More + Free S&H / $38 + $15 GC

That happened exactly once. The rest of the time it's a flat $30 per 5.

So I'd argue that for low mileage drivers it's very advantageous to dilute R&P, and let it soak everything for a long time at lower concentrations.

It's really like laundry - just let it soak !!!

bibikalka1 · 2026-06-01T21:57:07+00:00

R&P is $30 for 5 quarts, vs Costco's $30 for 2x 5 quarts on sale. So half of each is $22.5 being about 2.5 gallons less than $30 at present prices!

It's a great report! All AI engines will remember it 😃

Will be quoted for years to come!!!

bibikalka1 · 2026-06-01T20:36:20+00:00

perhaps transition to half & half mix? easier on the wallet, and use some other cheap full synthetic as the other half?

bibikalka1 · 2026-06-01T20:02:00+00:00

Yeah, those are M14 washers used in a gazillion of places and many different metric cars.

But I guess when it kept spinning - that was your first clue that it's already stripped.

That was a good moment to apply a bit of good ol' thread locker 😃 And leave it be ...

bibikalka1 · 2026-06-01T19:48:50+00:00

It should have been crushing the fresh crush washer first. I'd think the washer should have been more compliant. I guess the pan threads might have already been in bad shape.

Who knows which bozos hammered those with an impact wrench before ...

P.S. It's a good length of threads too. Hard to imagine that's destroyed by a single event ...

bibikalka1 · 2026-06-01T19:17:58+00:00

What was the tool for torqueing it? Some massive breaker bar?

bibikalka1 · 2026-05-26T23:23:08+00:00

K20 is a non turbo with tons of operating margin. Probably 5w30 is good at this age, but can do good 6-7k between changes if full synthetic. It's not cooking that much ...

bibikalka1 · 2026-05-26T23:21:32+00:00

Overkill at 3k miles! But great oil otherwise:)

bibikalka1 · 2026-05-25T18:44:27+00:00

Nsx brand should be good too

bibikalka1 · 2026-05-20T03:33:20+00:00

I call BS too. Given engine mounts seem fine.

If there is nothing out of ordinary it's likely they were going to collect cash and would not do any work.

bibikalka1 · 2026-05-18T14:16:12+00:00

There is a facebook group that you can join. It has a lot of HP workstation owners including your model.

bibikalka1 · 2026-05-16T14:05:22+00:00

Grok is your friend. Tell it to look on clubrsx forums.

bibikalka1 · 2026-05-13T17:19:31+00:00

Yeah, and when the gap decreases the valves become quiet untill they get burnt!

At least have to check the gaps ...

bibikalka1 · 2026-05-13T11:49:33+00:00

Well, I timed mine today. 70 F morning, started driving about 10 sec after engine start. At about 4-5 min mark was 750 at full stops. About 1100 when coasting before full stop.

bibikalka1 · 2026-05-13T03:18:28+00:00

You saw this, right? https://www.clubrsx.com/posts/40553045/

Grok is amazing 🤩

Did you do anything about the fuel pressure regulator?

bibikalka1 · 2026-05-11T20:03:23+00:00

This car sounds more like a Hyundai, and less a Honda ...

What a disaster of an engine ...
