Smoke in High RPM's??
I searched some and can't find this topic, I have a 90 Teg B18 and in the high RPM's its burning off oil. Can't think of anything besides the valve stem seals but before I go do them, I wanna make sure there isn't something simple I should check that someone else might have experienced. Thanks

compression test / leak down test, will only show you blow by... in other words a bad compresion seal (rings, or valves). now, oil seals only lubricate. they don't seal compression by far. with burning oil, you only have 2 choices. 1, valve guide seals (sometimes your plugs will have oil near the electrode to indicate oil comming down the valves), or 2... bad rings. on a leak down compression, you might.. might get blow by at the PCV valve, and honda has specs it can be wtihin.. but those are the 2 items to think about.
either way, both of them are sorta hard to find once you get the engine open. both can be deciving. high milage motors tend to burn oil... its nature.. you might want to thing about a rebuild?

Yea, I think it is time for a rebuild on this motor. Does anyone know a place where I can buy a complete rebuild kit or am I better off buying them seperate? Anyway, I'm gonna see what kind of comdition my motor is in first by compression test and what not, I think the service limit is 135 so I'm gonna see if I'm close or passed that. Thanks, keep the comments coming

chances are, your within the service limits of compression..
it doesnt' take much for a high milage engine to start burning oil... in fact, it only takes the ring of 1 piston to collapse, or fill with gunk, and start by passing oil to show your symptoms.
on the other hand it could be 1 valve out of 16 to start by passing oil also... its too hard to know.. especially when oil seals don't hold a compression seal.
time for a rebuild... face the facts.

well, if you do a compression test and the compression is low, take something small and dip it in oil and drop the oil into the combustion chamber then test again. if the number goes up, your rings are shot. your valves may also not be seating perfectly (probably aren't), but at least this way if you do it and the number doesn't go up but a few psi, you'll know the problem is in the head. oh yeah, and http://www.importperformanceparts.com sells various different levels of engine rebuild kits, from just basic re-ring to complete teardown and overhaul, and offers some performance options in their kits as well, like aftermarket pistons, high performance oil pumps, etc. interestingly enough, for another $45 or so, you can have them send you an engine kit with pistons from another engine of your choice . . . this is what i plan on doing and getting ITR or B16 pistons.
Yea, I'm gonna get a compression/leak test done this weekend hopefully. I'm gonna return with more info once I get more for some more advice, but odds are from what you guys are saying it's time for a rebuild
or GSR motor swap
lol, I'll keep you guys informed
Nice info. everyone

So if the compression test reveals time for a rebuild, what are some good sites for just a complete rebuild with maybe some added aftermarket parts on it., that one site you gave doesn't work, takes me to some search thing... anyway, I'll post results
My b18b has about 130k miles on it. After a compression test, they were all in the service limits except 1, cylinder 3 where it was about 20 less than the other 3. I start blowing smoke out my exhaust at about 5000RPM +.
Did everything I could, change out PCV, patch up any spots where it could be leaking (cam end plug, oil pan gasket etc).
It's either rings or valve stem seals like everyone has mentioned.
I'm looking for a rebuild, I think you should too.

Back from the dead, I finally did the damn compression test, lol. I have 170-2 all the across on my motor, I read over it real quick to see what I said. It still burns oil in the high RPM's like 5K or something and it burns when its cold, not now cause its warming up but on the cold cold days it would burn like at 3K if that. Anyway, when I did the compression test the plugs looked ok, they were all white which I think means good spark don't know exactly. Any ideas? Oh yea, I've had a valve tap almost the whole time, today actually it sounds like its getting a little worse so I gotta adjust them real soon like this week, would anyone know if that got something to do with it. If any got a write up on valve adjustment let me know, thanks for the advice
I had the same problem in my last integra, i asked advice from numerous supposedly reputable mechanics and they all said valve seals, so i booked it into a place to have the stem seals done, and it then turned out it was the rings were shot and the valve seals were in pretty good condition...so i had a complete rebuild at the stage with mild p/p and drove the car for another 20k before i sold it without ever having to top up the oil again.
BTW i also had a comp test done and was reading 200/210 across all 4 cylinders, so compression test means squat in that case

the oil control ring....doesnt hold compression it only controls the oil....have you check your pcv system...ie the pcv valve, hondas are notorious for getting blow by at high rpms due to high crank pressure

Yea i get what you mean now buy oil control not having anything to do with compression. No i haven't checked my pcv system, what all should i check, obviously the valve, i know i bought the car with a CAI but they did something with the hoses i think is wrong but i don't know, the main hose goes to the valve cover, the coolant hose for the TB is connected and i think the last one from the intake pipe is little and going to something round right above my throttle cable hook up to the TB. I'll check the PCV system tomorrow if I know what exactly to look for. Thanks for the help
Ok, did my PCV valve today, i tired cleaning as much as I can today. Still smokes though. I cleaned out a lot with carb spray, I had to adjust my valves today which is the reason I did everything. I sprayed a lot if not all the hoses, cleaned the TB and all that BS. My motor is all nice and quite now, lol, now if it only didn't burn oil. Running out of ideas except for valve stem seals and rings.
