Icon2 crap from exhaust :(

Ok so my car has been throwing crap outta the exhaust for the longest time on cold starts especially if I rev it... it appears to be water (obvious on a cold start) mixed with oil maybe? Some black **** though...

I have no oil in my water nor water in my oil... if I let the car warm up it still idles with some white smoke outta the exhaust and some blue at high rpm... compression check shows 180 across the board... however before this motor went in, itthe head was resurfaced, and got new valve stem seals at a shop...

So I have no idea WTF... is it possible maybe they put them on wrong, ex int. On ex. And ex. On int... any input is appreciated!

A guess to get the ball rolling...

Actual water droplets out of the tail pipe (especially when the engine is cold) is normal. Perhaps the water is carrying some soot deposits out of the exhaust with it, leading to the dark fluid? Hold your hand in front of the tail pipe while a friend cold starts it and revs the motor. Depending on the feel of the fluid that exits said tailpipe, you should be able to quickly tell if it has oil in it, or if it is just "sooty" water. If it is soot, maybe the excess soot is from your motor running rich? Do you have a turbo, chipped ECU, or other performance mods that may make your motor run rich? Even advanced timing could alter your motor's efficiency.

Next: Some blue smoke in your exhaust at high RPM on a motor with some decent miles on it is normal. Blowby at the rings comes with age, and is why rings are a "wear-item." Your motor may still perform well as you have broken it in over the miles you've driven it, or maybe even better then before, blue smoke included! I do not know all of the details about your motor, so this may not be the case. I'm simply trying to brainstorm with you.

Next: Perhaps the blue smoke and dark fluid exiting the tailpipe are related? Excess ring blowby that you only notice at HIGH revs? Perhaps the ever present (but only occasionally noticeable) excess blowby is leaving oil residue in your exhaust manifold, b-pipe, etc, and THEN, on the cold start, the water vapor from the cold exhaust is "rinsing" some of that oil out of the exhaust and out the tail pipe?

Last thing: The white smoke could just be water vapor, depending on the outside temperature. I'm an East coast man myself, and I can only assume that your California mornings are cool (~60 degrees?) and this may be normal. Maybe this water vapor is exaggerated by the age of your motor simply not running efficiently as it used to. BUT, like I said earlier, your motor may be brand new, and I may be way off base.

In Sum: Be honest with yourself: Have you owned the car long enough to know if this is normal or out of the ordinary? (I would think ownership of at LEAST a year would be needed, maybe longer.) Also, do you trust this "shop" that did this head work for you? Did they advise you as to the condition of the ring-lands while they had the head off of the car? Did they deck the head properly, or did they just "zizz-wheel" it's mating surface? Did they do the cylinder pressure check or did you? Very rarely do I see cylinders that are all EXACTLY the same sealed pressures across the board. Finally, are YOU knowledgeable enough to tell if these symptoms are portentous of a bigger problem?

The Fix: get your coolant system pressure checked by a different reputable mechanic. Maybe an actual Honda dealership, OR do it yourself, if you have the tools. This is where I would start.

(I don't mean to offend your intelligence with anything I've said. I found your post interesting, and I felt compelled to try and contribute, because of your higher than average post count. I do not pretend to be a pro, and am merely trying to help get the ball rolling with you. I hope that the others who are more knowledgeable than I, will contribute to help quell your concerns and solve this problem. I hope that those who would wait in line with bated breath to flame me, will take their static to the appearance/cosmetic forum)

Holy crap! That was much more than I expected for a first post! So thank you, and I don't feel insulted, I feel dumb for not being able to figure this one out myself... we expand and learn everyday though...

First off the car acts the same as it did running obd0, I just finished converting to obd1 and it still acts the same minus the high idle from my skunk2 IM/blox TB with no idle adjustment sadly... I think you may be right about the water clearing crap outta the exhaust, and I realize in cali as well that on cold start andon cold mornings it is normal, but what about when warm?

It is not as much, but still noteable from the exhaust, maybe because the colder ambient air? I drove the motor for a few months after purchasing my first 4 door with it, and after driving it, I knew it needed some love. I did a top to bottom gasket change, had the head resurfaced as it had a SLIGHT warp to it, and the valve stem seals done.

My friends and I have used this shop for a while but I took them the head dis assembled so as to not get raped on dis and reassembly, so maybe they did not like that?... once I redid the motor minus bearings and rings, it ran well, never had problems with it up until well I don't even remember when it began...

The car runs strong and well, I did another tuneup on in recently with new plugs and wires, still the same... also tried the seafoam treatment but not sure if it really helped... it never overheats, hell it barely even gets hotter than 1/4 between "C" and the midway point. Runs strong but seems very weird...

I was thinking about doing a quick bearing and ring swap, but right now I need the car to run for a couple months while my GLI goes back to the shop for warranty work.

Thanks again!

Well said. It is a Honda after all. So as long as you keep the fluids maintained, you should be able to beat the brakes off it. I wouldn't worry too much about it.


PS: I always hated receiving people's "half-completed" jobs at the shop. Most mechanics (No matter how friendly you are with them) frown upon cleaning up other people's messes, but this is true of most professions.

Mine does it too man. I don't worry about it. My engine is in great shape. It's just soot and moisture.

I wouldn't say it was half assed, I'd have done it myself, however I had to take the he'd in to be resurfaced so I paid them to put the valves and springs back in which were al individually bagged and numbered. I prefer doing my own work as much as I possibly can.

Well manny I know you have a fresh healthy motor, so if yours is doing it... I guess I shouldn't worry too much... ill have to shoot by your house once I finish it to take a ride in your hatch, and maybe you can help me fine tune my suspension.
