So have an issue where 2003 Civic is consuming oil: https://bobistheoilguy.com/forums/ubbthreads.php/topics/4647478#Post4647478

Pulled all 4 spark plugs and that's how they look like. Are they normal? Air filter is clean and no CEL on the cluster:

The white deposits show that the oil you are consuming is being burned (not leaked).

You need to determine the source of the oil, it could be something as simple as PCV, or you may have valve seals pooping the bed, stuck oil control rings...etc.

Thanks, PCV valve is new and have been replaced few months ago, no visible smoke at start up or during acceleration or deceleration and no leak on the driveway either. But definitely being burned and going somewhere frown

It all started after re-manufactured head cylinder head was put on. Are stuck oil control rings there in the head or bottom end? How can I check valve seals are causing this issue?

Thanks for all the help.

This is a good clue as to what the cause may be. Rings are in the block and if it wasn't burning oil before are an unlikely source of the oil burning after the head was replaced.
I would guess something along the lines of improperly installed valve seals or even a gasket issue (unlikely) like installed upside down with the oil drain back holes only partially exposed if that's even possible on this engine, I don't know.

Thanks Trav, we didn't install any seals inside the head, since head came all ready to go. We just prepared the surface, put a new valve cover gasket and spark plug seals, using my memory, I think that's about it.

As Trav indicated, if that's what was changed before this started, it is an immediate suspect. Where did the head come from?

Head was bought from ebay from this seller: https://www.ebay.com/usr/world.cylinder.head.ind

Apparently he had really good reviews for re-manufactured heads and hence I bought from him.

Wow, you are a brave man! LOL!

I would have had your original head reconditioned at a local machine shop of good repute. What was the cause of you needing the read re-done?

LOL, I can be at times laugh

Car jumped timing while driving, it needed quite a few valves and hence went for a re-manufactured head route. I still have the old head, worst case I'll just get it re-build locally and swap it in summer.

+1 on that.


I dont doubt the seller's work but when you do so many heads, you are bound to have some minor issues now and then. Your head MIGHT be one of them. At this point unless you pull the head it going to be a [censored] shoot as to what the problems are.

Did you check the pistons and cylinder walls when you had the head off? Pistons kissing valves isn't a one-sided scenario, there's the potential for some other damage from this as well.

Yeah, there was no visible damage. After above comments now I am leaning towards bad valve seals or leaky valve seals causing this to happen.

Start with a compression and leak down test and look at the bores with a boroscope. Its not that common but you may be dealing with broken rings or ring land damage.
If that's the case its good night Irene, rebuild or replace time. This job could get ugly real fast any which way you want to look at it.

Makes perfect sense, thanks Trav. I'll do a compression test and see what reading I'll get.

How many miles on those plugs, they look worn in addition to the accumulation on them. Are they iridium plugs?
