ok i got a b16a motor that would burn about 1 quart of oil after about 2,200-2,500 miles and burn very little radiator fluid. car smokes a little at high rpm like after 6k rpm. so i would always have to top it off a little. motor have about 110-120,000 miles and already got a new head gasket and the head resurfaced at the machine shop about 10,000 miles ago. motor is all stock just with I/H/E and itr cams. i do not drive this car hard at all always shift about about 3k rpm and mostly drive on the freeway to and from work only. will i did a compression test today and results came out good.

cylinder 1= 210
cylinder 2= 205
cylinder 3= 210
cylinder 4= 205

what can it be now since compression turned out good? im thinking maybe because of valve seals? car drives perfectly fine it never died or over heated on me yet.

Any leaks? With compression and head gasket good it must be leaking somewhere.

When you did the compression test how many times did you let it turn over on each cylinder?

fasthatch95

Does it burn out the exuast, but has tight compresion.

cleansi

valve stem seals, valve seats (compression) and most likly your cross hatch on the cyclinder wall looks like glass rings worn,

just my 2 cents

i just did the compression test today. i let it turned over about 8-10 times each cylinder and got all about the same results. some people say to just let it turn over 5 times but at 5 times they were all around 190 range.

not sure what you mean but car doesnt smoke unless its at full throttle after about 6k rpm and gradually to smoke a lil more until redline. dont smoke a whole lot but some.

fasthatch95

Thats what exactly i thought unless he has a major oil leak somewere.

well to tell if its valve seals you let the car sit for a few hours and let engine cool down, then right at start up there should be some blue smoke from exhaust, if no and you only see blue smoke at 6k rpm, which to me is pretty high and not being gentle with engine, and some info for future: compression test does not show condition of oil control rings (its the only rings that scrape off oil from cylinder wall and they provide no form of sealing pressure, that is the job of the top two compression rings) another thing overlooked on oil consumption is pcv valve, if you've replaced one recently it could be wrong and cause oil consumption, or if the pcv valve is worn out whichs allows excess crankcase vapor to be drawn into cylinders, i would recommend replacing with only oem part, one thing you can try that is out there is soaking the the cylinders with a solution called top engine cleaner for a few hours, although i think honda recommends not doing it ive read from a few people with positive results, GM makes a really good product that was designed specifically for cleaning out oil rings because they can get stuck inside the ring lands. make sure to get most of cleaner out before you crank over your engine, you can hydrolock it,

It sounds like the valve guides i had the same problem before i rebuilt my head and had new ones pressed in

fastrxu

How would he know if its his rings?

97ej6dx

iT woulnt be the rings because there would be a loss in compression and the piston would flop in the cylinder. More likley the Valve guides are the problem. They are the cause of most of Oil burning

mynameizstitch

valve guides huh? hmm. i will have to look more into that and about the pcv valve

shogee

valve guides and seals show up at start up, it smokes from 6k to redline = oil control rings, they cant scrape off all the oil, another thing to consider is how worn the bearings are because if they become worn out they'll start splashing too much oil onto the cylinder walls, try the top engine cleaner

yeah kind of seems like motor would just need a tear down and rebuild. there alot of factors to it here that may cause it to burn oil. if i do tear it down and rebuild ima probably do everything all at once like new bearins, new rings, hg, new valve seals, new valve guides. seems like its alot of work maybe i should just find a used jdm b16a with low mileage and in good condition in the streets for around 6-700.

I had the same problem with my prelude. It had around 120k on the motor and was burning a considerable amount of oil. After a rebuild (rings, head gasket, valve seals) it hasn't burned a drop. However, it is a bit different since the H22's have the FRM cylinder walls, and burning up to a half a quart every oil change is within factory spec. If I were you I would change the rings and valve seals at least. Good luck on solving your problem!

i would just rebuild what you have. for that price you can have yours rebuilt and it's NEW not "low mileage and in good condition". you never know what some one else did with a used motor.

mynameizstitch

will a rebuild is going to cost a lot more money. for parts and labor.

I have the same problem my 97 h22, it has about 128,000 miles on it and for the last six months or so its been burning excessive amounts of oil through the exhaust.. it builds up all over my bumper =/ start up and idle I get a whitish colored exhaust but when i rev it spits out a black fum.. and we wont even talk about vtec.. I haven't really noticed a lose in power and I have our basic I/h/e set-up. Could this also be a rings, seals problem? If so does anyone kno a good honda mechanic in MD?

shogee

sounds like the engine is running rich a different issue

shadowlude97

Is there a way I can lean it out on my own or is that something Id have to get a machenic to do??

shogee

do a fuel pressure test
