OK here is the deal I have a b18c1 it has maybe 90k give or take. i have for a while now been smelling a strange odor in the cabin of the car, like exhaust fumes but I just had a full exhaust with test pipe put on and I have verified that there are no leaks. When I drive the speed limit nothing crazy, I still get the smell every now and then and when I get on it, a good size cloud of smoke comes out and makes the smell really strong.... does this sound normal? Also, I just had the car dynode with Hon-data s300 and while on the dyno at the first pass it ran mid to high 140hp/with the cat still on. the guy doing the dyno said he didn't think the motor was very "healthy" due to the low numbers, then after a couple more runs and tuning we got to 164 hp with the cat taken off. He said that i may be burning oil and I may have problems internally because there was a lot of smoke coming out of the exhaust when I was on the dyno.

Mods on car when dynode:
greddy headders,DC Sport catback,skunk2 I'm, aem intake, hondata s300. He suggested a complete rebuild I don't know and I'm going insane thinking that my engine is almost a goner. I would also like to know if those numbers are normal (dyno numbers).


I'm working on my 99 civic sedan i just added a b18c1 with a stage 1 clutch, slowly making progress. to all

 

Do a compression check and tell us the numbers that will help tell you if your engine is healthy or not.

 

^ a compression check will quickly tell you if the problem is in the top or bottom end; or if you have a problem at all.

What color is the smoke?

its kind of grey. i have never been behind another gsr to see if theirs does that thats why i ask.

 

It is possible that you are burning some oil; that is not uncommon.

Did you get an a/f reading when you got it tuned?


It wouldn't hurt to do a compression test.

Compression Test 101

If you are able to, you could do a leak down test as well.

Leak Down Test

 

thanks for the info i didnt know that a comp test was that easy i will do one later today and post the results.

 

hey sorry for taken so long i will be doing it tonight i found a guy to do it for me but he flaked two days in a row so i went out and got the kit and i will be putting the results up later today

 

ok here it is cyl 1-2-3 210 cyl 180....we dropped some oil in the 4th cyl and the compression jumped to 240ish...bad news for me

 

um. That's not bad enough to do a rebuild lol. I personally wouldn't worry too much about it. Save some money up and just build the engine, rather than waste money rebuilding it! It still has a lot of life left in it it sounds like. And ALL GSR's smoke quite a bit because when the engine crosses into VTEC, the ECU richens the fuel/air ratio quite a bit, causing it to smell bad and emit dark smoke.

But... If it worries you... I would do a build

it does worry me but i was doing some research and what i will end up doing is replacing the one cyl and leaving the rest cause they are still healthy and just go turbo with ethanol injection. with ethanol it will cool the block thus relieving some pressure on the block that the turbo causes. over all saving the block wear thats caused by turbos. does that sound good? cause i dont want a track car all i want is civic that breaks 200-220 whp

 

I had the same problem the head was goin plus with a B18 you numbers should be 170ish. The smell in the car is normal without a cat. But the smoke is not. your head is def dead if its white smoke and if its blue the the engine is tired. and all LS's burn oil so if its not excessive its fine.

 

mmm. I am still learning about what the best thing for a turbo setup would be, but as far from what I've gathered is that to make 220 WHP on a B18C1, you won't need to run too much boost, therefore, I don't think you're going to need to do too much to the engine like ethanol injection. I think that if you want to repair the one cylinder, then you should definitely make sure you get it taken care of right, because a lot of places will do a half-*** job when they repair an engine. I think your best bet on a rebuild for that cylinder would be a slight bore and hone just a small bit, then buy a bit oversized piston to fit. Most places will simply re-hone the cylinder and put "oversized rings" on the same piston. Although people say that it works, I hear mixed reviews on engines that are rebuilt in this way, whereas no bad reviews on engines that are built correctly.

As far as engine modifications, I would just put some ARP head studs in there to avoid any head lift, and run a smaller amount of boost (like 7-8 lbs.). This amount of boost, combined with the higher compression of the GSR engine will amount to some good and responsive power.

* Anyone feel free to correct any of this because I'm still learning about this stuff too!

 

If its smoking it could be a head gasket if I'm not mistaking

 

mmm, well I think if you're noticeably losing compression from a head gasket leak, there's going to be a lot more going on than just a bit of smoke emitted from the exhaust, and it wouldn't really run right at all because there would be water getting into the combustion chamber and oil into the coolant... 180 PSI isn't even that bad for 1 cylinder though, I've seen cars running with less than that.

It could be weary piston rings or maybe even something as simple as a terrible valve adjustment that needs to be tuned (that's being hopeful) or it could range to a burned valve (although this often causes more of a loss in compression than that) or it could just be that a valve isn't seating right (this would be an easier fix than replacing the piston rings correctly)

what do valve adjustments consist of? also keep in mind that i am burning oil when i hit high rpms..a good amount of it...

thats a damn good idea i think i may go with that...any objections?
