Using Amsoil Signiture 0W20 or 5W20 doing 15 000 mile oci.
WOW! Looks like it was just built!
Another win for Team Amsoil! Love the stuff.

You gotta be putting us on! That has to be a new engine you got pictures of. lol.
Nice and clean. I had three Acuras between 1990 and 2007. One thing about Acura engines from that era: do the routine maintenance and they run almost forever.

This is exactly what I was thinking. The cam lobes on my K24 equipped Accord have a darker line running down the middle of them. It has 128,4XX ish miles.

Looks great, something about a clean engine puts a smile on my face.

j/k folks. It's practically looking like new, so enjoy and keep doing what you've been doing (oil-change wise).
Q.
Yup, won't change a thing. Amsoil and other high end oil would be a waste in my car.

Yup, the old timing belt had 85k on it and looks like it can re-sold. It was still nice and tight.

I always warm up my car 30secs to a minute. Never drive off right away. Not sure how valid this is but i think that WOT keeps the engine clean and running really well. I WOT a few times per gas tank.

Not sure what you mean by self-destructed.

Just for fun, here was mine at 120k with the 5k conventional changes:
These are fantastic engines. Long life, peppy and very fuel efficient.

My experience in the junkyard of taking off valve covers from hundreds of honda B series and K series one thing I've noticed is that B18's and B20s always seem slightly cleaner under the valve cover than K series even though its an older engine series. I'm not sure how that applies to cam lobe wear just thought I would mention it.
Seems like K series put more wear on the cam lobes.
Here's my K20 at 170k km on synthetic 5W20 changed according to MM.

I believe the valve springs on the K series engines are stiffer and mark up the cam lobes. The VTEC probably requires stiffer valve springs to prevent valve float at high rpms.
garlicbread, your engine appears majestic and likely at the optimum change interval to remain at an efficient, healthy operation. Just broken in.

K series Honda engines all use roller style followers in the valve train. This is much smoother and causes less wear. Most B series engines use the old style flat tappet valvetrains that wear down over time especially after the mandate of lower zinc content in engine oil. So if anything K series have much less wear in the valve train, but I think the roller bearings leave a slight indentation on the cam lobe and the non roller B series cam lobes are shiny because of the stressful bearing less metal to metal contact.

I would like to take some pictures of my CRV's K24 this spring when I get around to replacing the valve stem seals. From the oil fill cap, the valve-train looks pristine, besides the typical slight varnish on the oil fill baffle. My K24 also has the 'normal' scuffing on the cam lobes, already there before I installed the bypass filter setup.

Thanks. Routine oil changes, minimum 30 second warmups, drive gently until 185c and some WOT has been my driving style since buying this car. That's my not so secret routine

Why do you have to replace the valve stem so early? Make sure to post pics!

Garlicbread, i am not sure, i found shortly after i bought it last year that the seal(s) are gone. I have some performance viton units going in and yes i will post pics. I am guessing that the oil the previous owner used was not good for seals. Other than that, its in great condition.
Looks good

Which one are you referring to? I see massive varnish and wear in all of the Honda pictures.
