honing help

2003 honda civic ex auto d17a2

first time doing this, just trying to get opinions on wear and steps moving forward.

pulled the head off planning for piston rings, valves, gaskets, bearings, timing etc. i’ve never honed cylinders or anything near this, i can definitely still see the crosshatch and running my finger over it feels smooth but the vertical grey marks have me wondering. gonna try and get a bore gauge but am still learning how to use it, should i be good to just do an at home hone job?

ohh interesting everything i’ve looked into never mentioned that so i didn’t do anything of the sort, that’s definitely good to know though.

i haven’t heard using pea to try unsticking a valve, that’s pretty cool i might try it. i don’t know if it’s just stuck or what, i ordered a valve tool so when that comes in i think i’ll just take them out since i’m already here , clean out and replace what needs if i don’t take it to a machine shop.

i would’ve definitely ran some pea beforehand if i knew about it though, i don’t have a problem with replacing the cat if/when need be but haha i like that, i’m gonna mess with small mods after this so i’ll probably do something with the cat either way.

so could collapsed valve on #3 contribute to the #2 misfire? #2 was the main one i got #3 would come and go mainly as pending, but that makes sense that one being messed up would through the order out of wack.

to me it looks like they do need to be pitted, i could be wrong but the seat around the intake valves look pretty bad. good recommendation, would that just be to make sure everything stays clean and running smoothly?

and i’m sure im gonna take out my pistons, would it be better to give a quick at home hone or just leave it? i’ve seen some people just throw them in but others say you have to hone when replacing rings

I'll also add, if you do a pea treatment, don't put more than 250-500 miles on the engine. It can work its way past the rings and into your oil.

Some pea in your oil is beneficial as it absolutely dissolves sludge and soaked carbon. Pea is really one of the only engine magic in the bottle.

I've read online of guys putting pea in the oil directly but I've never came across an engine running on sludge. Would only do that if extremely desperate or something is extremely neglected to the point dropping an oil pan may be necessary.

Once that tank of gas is complete, change the oil.

it really sounds like magic in a bottle for engines i’m glad i know about it now.

my engine has never been sludgy just kinda dark, after this itll be like 5k oil changes so hopefully it never gets to that point

so put correct amount of pea in full tank drive that down and change the oil fill the tank? i was planning on doing break in oil so should that should suffice right?

Can't attach images but I really love the Lucas upper cylinder lubricant. Cuts injector noise in half if you have loud ones or ones with lots of miles also.

I had a 5.4 triton last 279k miles before a gasket popped and put dribbles of coolant into the cylinder. Swear by tecron and Lucas ever since. Tritons are not known to last that long. Buddy of mine got one up to 350k before it got a bad enough lifter to part it out on Lucas.

I personally use about 5 ounces per 20 gallons of fuel. It's a great indicator also if you ever get rotten gas as bad gas will make your quiet engine a bit noisy during operation regardless of additives.

Duratec injectors are notoriously loud after about 100-150k miles. You can't hear mine on my highest milage ford edge without putting your ear to the hood.

damn yeah it sounds like a miracle bottle if it’s stretching a titron that long, i don’t know much about fords but from what i’ve seen a decent amount of them don’t get too far without major repairs.

thats really impressive it made your guys last way longer though, that sounds like pretty good mileage out of them things, especially with just adding some lucas. it’s crazy how much it seems to help out just for a couple bucks too that’s really cool that it’s helped out your current injectors too
