A question for all you motorheads out there. I've searched all ends of the HT website which has yielded little information.

#122 has a fresh built engine. I have done a proper break in and have changed the oil three times in the first and only 60 miles I have so far on it. Compression tests are exactly 210 across the board and a leakdown test resulted in 4%-5% across the board respectively. The plugs are black (like carbon build up) not oily.
The #2 and #3 pistons look like they are wet with little black specs of **** on them.

All gaps and clearences are within spec. Every torque measurement has been checked.

Here is my problem. There is moderate oil consumption and durring decelleration smoke comes out the exhaust. What can this be? Any help would be greatly appreciated!

Aloha,
Brandon

Valve seals, or something.

That sucks, how bad is "moderate"? I guess you don't have enough miles to tell.

Are you sure it's oil and not just fuel? Does it smell like oil?

Goodluck

Edit, maybe it's just a PCV valve or something... not sure how yours is set up. Probably valve guides or seals.

 

Moderate like: I can smell the oilyness and faintly see it. The plume of smoke is not thick to where I cannot see through it. It is slightly noticable.

 

damn brando, sorry to hear these problems with a freshly built motor. hope you work things out. i have also a huge headache to deal with.

 

It's alive, it's alive.........mmmmwwwwwaaahhhhaaaahhhaaaa!!!!!

 

<FONT COLOR="blue">Haleiwa-Brando (8:38 PM 8/12/2005): </FONT>valve cover breather isn't hooked up to anything. The PCV is hooked up to the Intake manifold.

Under vacuum, your PCV can spit a lot of air/oil/whatever through that hose. I would run it to an empty bottle (20 oz coke can?) using a few feet of 3/8ths inch fuel line. It's a quick and cheap test. Also you can take your PCV valve out and shake it to see if it rattles. If it rattles, it isn't stuck.

Eventually, you should probably run that to an catchcan or something. Boost will hold the PCV valve closed and it won't allow pressure buildup get out of the crankcase as well.

 

Cusco catch can is on the way. We JUST did an oil and filter change. The PCV checks out to be: good.

 

&lt;---Apparently whoring

Try a nice long decel, make as much smoke as you can right before you stop the car. Pull the plugs, look for the oil. If it's just one cyl, you gots a problem. If they all look "roughly" the same (2/3 never look quite the same as 1/4 to me) and are dry, then it's oil coming from somewhere else.

Turbo seals can leech oil, but I don't think it's fine enough of a spray to make it all the way through your IC/piping/etc while you're decelerating. Maybe, if the oil pressure was way too high, but seems very very unlikely. Look for oil in your charge pipes, or spraying out of your blow-off valve.

How much does one put themselves through before they have had enough... or.. just get a stock engine so the car is useable/?

No offense - but this engine sh*t has prevented you from going to expo, and invariably delayed your cross country journey indefinitely. Seems like it can't be very much fun to have downtime of 99.5%. :Shrug:

 

you dont and didnt need to be that excessive about changing the oil that many times.

Piston rings not properly seated?

 

ur still in wa? any time to kick it before u leave? i come home sunday

 

All good advice here... Not much for me to say, But drive it a bunch more and then worry about it. It could be simply that the motor has not settled in yet.

Would you hurry the F up!

 

What color is the smoke? Sorry if I missed you saying it already.

I would switch it out to a "coke bottle" catch can in the meantime, and get a vacuum line cap for the intake manifold port.

One thing I noticed on my motor was that I seemed to have a lot more blowby until after about 1000 miles.

 

I agree Rings maybe? you said 4-5% on the leakdown right?

 

My not so knowledgable brain (still recoverig from 311 last night) thinks you should put a few more miles on it before you say theres a problem........

I think it just needs some more time to break in

 

All good advice. I appreciate it. For fun I changed the PCV valve, and that pretty much eliminated the problem.

 

wow...should have been gone after 60 miles. compression #'s dont tell you anything about the oil rings though. check your crank case ventilator on the valve cover, if thats smoking, then you're fine. bearings still need to be broken in. oil changed 3 times at 60 miles?...jesus. the way i usually do it is i change it every 250-300 miles then once i reach 1000 then its normal procedure again. maybe the number of oil changes has some effect on your motor?...it needs to be rough to break in. what type of il are you using?

Well, let me reiterate (spelling Chris F?) on this quote:

The oily smoke is gone. Which is now replaced from blue looking smoke, to white smoke - every now and then. There is still carbon looking flecks on the pistons.

The two outer spark plugs have carbon build up, and the two inner spark plugs look perfect. Perhaps this would add a bit more insight on what it may be.

Also for break in I'm running stock injectors. Fuel pressure is good. I'm also running Neptune. VTEC is disengaged. Boost is cut off at just under 1psi for safety. Wastegate is wired fully open.

Thanks again for any help.

At this point in time and having know of all the bullshit you have gone through i am left to agree with Chris. Sorry to hear of yet another, INCONVENIENCE i suppose we'll call it.

 

I do agree with both you gentlemen, though I see this as a minor inconvenience and a small problem. This is the setup that I want, and I have made many sacrifices all winter and spring to make this happen. I worked the only job I could get, which was minimum wage and literally lived below the poverty level for nine months. No sympothy wanted from you guys and gals just sharing. I'm completely happy and cool with the decisions that I have made. Instead of talking about 'what if's' and 'should haves' there is nothing to do here but move ahead with the goals I set out to do. Im on here asking for help.

Any help is still greatly appreciated!
