H22 90 Accord Blue Smoke .. HELP !

[H.M.]

x10
Blue smoke is oil being burnt pre-ignition.
Its most likely a bad valve seal/guide. Your mechanic is an idiot.
.....Hope my eleventeen paragraphs helps man, because I felt it was needed so you would wrap your head around it.

That was a great tutorial for me. I really appreciate you typing it all out. Thx!

the only way for us to see if toycar is right or PRCB7 is for OP to get a leakdown test

GET IT DONE!

However, i am going to have to go with toycar as well. a broken ringland IMO will not cause blue smoke. you have some kind of oil leak in a cylinder and with most cars it is usually something in the top end i.e. valve guide or seals. All a broken ringland is going to do is cause noises, loss in compression and thus poor performance.

Either way, but did anyone read post 24?

[PR CB7]

Post 24 just tells us how stupid his mechanic is

there is clearly nothing in the h22 head that will make the engine smoke blue excessively period

The reason why I say is a broken ringland is because of experience, a head problem wont foul a damn plug, a head problem wont make the motor loose comp while smoking too
Just because that scenario didnt happen to you doesnt mean its not the problem, 1 ringland broken wont affect the engine at first, but the more the engine keeps running then only thing that is holding it is the rings, eventually it will hit the oil land and cause blowby to sweep into the cylinder

Yoy guys are forgeting the main factor, and its not the actual smoke
He's fouling a plug, for a plug to foul excessive oil is getting in the cylinder and or lack of compression doesnt let the mixture ignite

Believe what you want, these are facts
To believe this is a head problem is ridiculous

I am really surprised you would say this, and it makes me question your own knowledge.


Very first link I clicked when searching "symptoms of a bad valve seal"

Im not stating that you are entirely incorrect. Its not impossible to get blue smoke from a bad piston ring. Its also possible, and a lot more likely, to get black smoke from a bad ring.

A broken ringland though, seriously? You just jump out and claim the piston is broken?


Why?


And wether you agree or not, you have to realize that oil leaks down from above the valve, through the guides, seats and seals when they go bad.

Where do you think the oil goes? Its gets burnt.

And when it burns, it burns blue.

a oil leak from a valve seal wont cause a plug to foul nor will cause compression to drop
you can even remove the seal and it still wont foul the plug

you post a link refering to your typical domestic engine, where a valve seal is huge, have you ever seen a honda valve seal?
not even on a 300k h22's ive seen a valve seal do this

once a land is broken it might not start smoking, but definitely you'll see a loss of compression, a healthy h22 should have 210psi+ comp
a broken land will show numbers in the hundreds
it will depend how much abuse the owner gives it, the time were it will get worse and hit the oil control ring, once it does, compression will get really low, and it wont longer be able to ignite the fuel fouling the plug or it will let oil back into the cylinder fouling the plug and also excessive blowby will create caos in the pcv and breather

the problem is not head related, the problem is bottom related, its a piston problem
im willing to bet on it to, so before you post another generic link educate yourself a little better, there are things you just cant find on the web
