almost all of them go out that way and more than half are developing one as we speak...
first one I bought a used core the guy said ran fine turns out had a spun bearing
I had to get the car out of the garage like yesterday so I went to pick and pull and got a used bearing from 91 civic of same color. sandpaper the rod journal and slap that sht in.
motor seized halfway down the street I put it in gear and rocked that btch loose. it started again lol.( I was pretty surprised)
but had a massive rod knock...
drained the 5w30 next day and put 0w30 mobil one.
started up and after few days the rod knock only show up for less than a second during startup.
drove that car for 8 months
then I decided to test this and switched back to 5w30. rod knock came back right away and I sold it...
my wife blew up a motor in her work civic
I swapped a d16y7 from junk yard. had a rod knock put 0w30 rod knock gone. drove it for another year and a half daily
same with my buddys car. I tld him to try and he did. drove the car for another year before it blew up
had a built gsr motor for 2 years, made a mistake of using felpro cam seals and supertech valve seals after fixing headgasket leak. they both leaked like mofo and oil pump went out after 200 miles due to oil loss. I put new oil in it and drove it for 2 days with bad oil pump not knowing that the engine was a dead man walking since it didn't make any weird noises and ran fine. (the only 2 days that I didn't have my oil pressure gauge hooked up after rebuild.. it fn got me good...
on the second day it started getting a lot louder so I took the vc off and pretty much found a dead motor full of metal shavings and it was still running with the 0w30 in it.
but those are extreme cases lol
usually I can hear and feel the motor running and cold start smoother when switching from 5w30 to 0w30
Yeah... I am a Honda guy too. Somewhat. I like my Honda, I like my other car more. Sourced a D16Y7 (? Y8? It's a year 2000 car so whatever, going into a previous generation EJ1, parts from all years in the range) and I'm going to verify the engine's health soon, with compression tests and such. Did not think of pulling VC, to look for shavings (? Thought you looked in the oil pan. Anyways) I'm probably going to put 0W-20 in it, just like I do now, since Honda says you can. They back-spec'd it, and put 5W-20 in since 2001.. 5W, 0W, both are 20 at operating temp.
You sure had some [censored] Hondas. The Honda forum would probably have guided you back to some nice builds. Especially on that Y7.
I would also agree with you that quality 0W oil can be felt in smoothness, mostly on cold start followed by turn-key-and-drive, and depending on how the engine takes to the oil in it even if via the butt dyno, during the whole run. I started the 0W pursuit about three years ago and have been using 0W and 5W when 0W was not around ever since. No bad results from oil choice. Engine situations are a different story.
Have a nice day, and that GSR.. B18?
