Hello,

My engine is producing blue smoke (oil burning) when i decelarate an then acelerate around 6000rpm or above.

I have new Honda oem valve steam seals and new bronze guides from supertech.

The car pulls very nice.

No smoke on start up.

No smoke when accelarate.

Whats your experience tell you people?

Guides?
Seals?
Oil rings?

Many thanks

Could b ur oil control rings

Did it smoke before you had new seals and guides put in?
In the same rpm specific area's?
Mileage? Engine? Stock ECU/tune?
Who did the head work?

If you have any kind of oil contamination into the combustion chambers the ECU is gonna be working extra hard to keep some kind of performance in the high RPM's, thats why I never worried about a quick poof of smoke past 5500 rpm's especially on my beaten stock H22 that sipped a 1qt atleast every 1000 miles. I had to top it off with a qt every month. I mean if anything your burning the **** out and I figured that was GOOD Lol. On decel though there is some extra pressure going on, thats why they tell you to do that to seal the rings on a fresh build. I'm not sure which way its going tho. so you'll have to wait for some more inclined tech's. But before that you should try and do some more research and troubleshooting to give us some more info. like leak down test, pressure check, stuff like that so they can actually help. To even be able to make a solid "Guess" // Shot in the dark to point you in the right direction we need to kno everything. Do you have it cammed, did you not spec your spring heights for S2 pro3's and put new seals in, and now there ruined? stuff like that?

$5 says its the valve seals and or those bronze valve guids..

Was everything as far as the cylinder head freshly rebuilt when the valve seals and guids were assembled?

Darklord

No it doesn't use to smoke before.
120.000 Miles. B18C-R. Tuned S300.
Pressure 210psi in all cylinders.
JUN type 3 camshafts degreed in. JUN springs.


I don't know what is causing this smoke but i'm poiting to the guides. I have been seeing other examples and I know two more engines with these supertech guides that do the same symptom.

Ok Your valve guide installed height probably werent low enough for the JUN 3's and your retainer 2 seal clearance was insufficient and all the seals are banged up and gone.

Or who ever reamed and honed your new guides made to much clearance, thats really a no brainer tho. Either way pull your VC and start inspecting, more than likely gonna have to pull the head if you cant deal with the smoke idk how bad it is soo

Darklord

The valve guide installed height are ok, they are all at 12,5mm.

Yes i think so the guide reamed was not done well. All i'm going to do is to take the head out and replace the guides to oem Honda.

Do you know if the Ferrea guides already come reamed from factory for the 5.5mm oem valves?

If you just put a freshened up head on a 120k block it's likely to start consuming oil past the rings. Still consider an installation issue in the head but at that age, the bottom end is going to be a bit tired.

Darklord

Yes i will start a 85x87 build, anyway that could be true if the smoke was always present but it only produce smoke on the transition from decel to accelaration is only a puff of smoke and then it stays clean until the rev limiter.

Well 12.5mm plus the seal on top is atleast another I'd say .130" idk you won't know till u get back in there. If your new at this you need to triple check things and if you pay someone, you need to also check there work to. I dropped my head off for a 3 angle vj and to spec my spring heights and they told me I had to use my old stock spring bases. And skunk2 says if you use there b series springs for h you need there bases to make a 1.320" spring height so ya. And they were a specific cylinder head shop. Like I said u can't trust everyone's work. Double triple check everything.

You also might just be dealing with some oil in the breather tube then or PCV, maybe your catastrophizing?

Idk what your running but if I made a penny every time my 5g 01 Prelude blew a puff of smoke Lol I would be rich. Maybe your just being to cautious because of the new head install.
