ok so my im trying to figure out exactly what i need to fix.


my compression specs:
cly 1: 204
cly 2: 185
cly 3: 200
cly 4: 205

Leakdown:
cly 1: 82
cly 2: 88
cly 3: 88
cly 4: 88

Car Runs strong as hell. but its burning some oil. im trying to figure out if im looking at headwork...valveseals? etc? or bottom end. thanks.

so it burns oil... keep driving

serr38

thats what i was thinking

dk127

well, if your burning oil, you'll probably need new rings, plus that compression was a bit off. you'll need a rebuild.

how many miles are on the car?

serr38

engine has prolly like 85k on it. and one6 ILL garage and profunction told me the compression is fine and it prolly just needs valveseals and guides or a head rebuild.

you're not the only one...my R burns about the same...and its really irritating, somedays I have to drive thinking if I have enough oil in my car. =(

serr38

this is how i drive everyday.

It could be your valve seals too. Also, did you adjust the valves before the compression test?

torneo sir-t

my teg us ta burn sum oil 2 did the valveseals and it help wasn burnin half as much oil after dat

Willing to bet that if you replace the rings and just do a nice hone job it will fix both the oil consumption and compression issues... It isn't expensive nor hard to do if you have decent technical skills.

GL with the fix

serr38

dont have the money for the rings i just bought this car. and no didnt have the valves adjusted

racebum

eventually you will burn a ringland or exhaust valve. just keep driving till you do & replace & rebuild once it blows.

it's probably ring related and if it were my car i would just do a hone with new rings n call it a day. new rings and valve seals do wonders to your average high mile b18c

IBriaIN

I'll keep what you said in mind...I have the money for it...but no time...Probably once I graduate school.

Nothing new. I do the same thing. I could solve the problem by not hitting v-tec but thats boring.

i think type r are the worste my friend has a py one and his burns oil just as bad as mine and he just rebuilt his not to long ago but me and him both have vafc 2 and once i put mine in thats when it really started smoking

My car burn though oil, but runs like a West Virginian virgin, so I just keep adding oil. Planning on my rebuild next year.

mine to burns like a bitch but pulls like a champ

serr38

hmmm

my old one used to use about as much as yours (actually looked like a mosquito truck going down the road), replaced rings and did a hone job, it quit burning oil after that.

sti grip

rebuild time !!!

For the guys burning good amounts of oil, do you guys have your spark plugs fouling up?

my caR burns its fair share of oil and prior to this summer when i did maintenance after taking the car out of storage, i noticed that my old plugs had this weird white crusty buildup on them. best i can describe them is they looked like calcium deposites...however, none of them were oil fouled

esco115

I would check ur valves, valve seals, and piston rings... < follow the steps!

Oh. Reason I ask is because I just recently had my head rebuilt on my EM1. All new seals, valve guides, valve seals and all clearances checked and were to spec on the valve seats and valves themselves.

But prior to the head rebuild, my car went through oil like crazy like you guys. And only one plug (cyl 4) kept getting that white crusty build up with black fouling. I thought the root cause were bad valve seals and guides.

But now with my rebuilt head, cyl 4 still gets the black fouling with the white crusty build up. Compression is fine across all four (200ish PSI) and the oil burning is about 1 qt every 2 weeks or about 500-1000 miles. So not too crazy as before.

I guess my oil control ring/ring land is busted in cyl 4 cause the block wasn't touched when my head got rebuilt (it was assumed fine, no scoring on the cyl walls).
