something is most likely wrong with the motor i feel.

 

Well I hope you're wrong, in that it's nothing with bottom end; either way I looked inside the cylinders, but the camera is kind of crappy to see well. But I noticed that 1,2,3 piston tops are nice and dry and the 4th one is covered in grease/oil and from the looks of the spark plug, it seems to run leaner then the other 3.

Is that the common thing in Evo's that the last cylinder runs leaner (reminds me of Subaru's)?

I'll be putting in oil dye sometime tomorrow and after a little bit of driving take off the intake and exhaust manifold and look for traces of illuminating dye there, also got GSC Viton Intake and Exhaust seals that I"ll be replacing sometime next week, as it seems to be the only remaining piece that might be the culprit to all this? I don't know I'm running out of ideas, I should have just bought the AMS Crate Engine and not bother with this ****, where even builders aren't helping and I'm the one eating the costs and pulling my hair out in order to find out what's wrong.

 

I like some if the comments about how I should be helping. I don't have the car here, I can't do much but comment and watch ****ing videos like the rest of you.

So, I watched the videos. First, I don't know who tuned it but it shouldn't look like a diesel truck under boost, it's ridiculously rich and is going to make the tops of the pistons look black and greasy. #4 piston will also look worse many times as the EGR is on that end and if functional I see that cylinder getting dirtier. Last, the amount of oil you are losing the car should like a poorly mixed ratio 2 stroke smoking blue as hell and I see very little to no blue smoke.

There is my input again. I will also provide some extra. Nearly every EVO we see now-a-days is a hacked together pile of garbage, it is sad. You can get a heart transplant as a human and if the rest of you is a big pile of fat crap that new heart won't do you any good, a car is the same way. We provided a heart, I don't know what's going on with the rest. The oil consumption is high but it is so high the car should be belching blue smoke and it is not. We installed new rings of course, we also went through the head and installed new seals. We build a LOT of engines, actually four more left the shop today. There is no reason for it consume oil based on what we did on our end.

Also hard to believe that you got a turbo off an EVO9 that had 1,000 miles on it nearly 7 years after the EVO9's production. If the valves/exhaust ports look good then the oil is being burnt after the head, that leads to the turbo.

If it were mine the first thing Id do is get it properly tuned to get rid of the diesel smoke and then maybe you can see if there is any actual BLUE smoke.

Good luck.

 

BTW, AMS will gladly sell you a crate engine still, I'm sure. Two engine builders, same oil consumption and no blue smoke from a poorly tuned car but it needs an AMS crate engine to solve the problem......great comment, makes me want to come back to the thread and help more........

 

previous tuner had this car running super rich. car made no power and was a complete turd. i retuned it and he emailed me saying "car is so much .. faster "

bbong David's engine has nothing to do with your smoke issue. i can assure you that 100%. posting you should of went with AMS is uncalled for. His engines not at fault.

If its still smoking with my tune then its probably the turbo like David just said. but pointing fingers at the engine builder is not the right way to go. I tune his engines all the time in customer cars and they run just fine.

 

David, if I offended you I apologize, all I was trying to get is some suggestions and or ideas, I've been at this for a while now. The turbo looked immaculate, who knows if it had 1000 miles or 10000, all the owner said is that he opted for big turbo kit and this one was left in the garage until he got around cleaning it and selling the turbo.

I got it retuned and it still smokes like a diesel, maybe little less but it's still there.

I got this car hacked up and I started unhacking it and bringing it back to stock PCV, Hot Parts, looks etc. so I doubt that it's hacked up as I usually take very good care of my cars and if anything is out of ordinary, I try and fix it. I'd have to agree with you though that nowadays Evo's are just stitched together and they expect them to be reliable cars (as when I got this one).

If you also changed the Valve Seals then that is not it, and as you pointed out what I thought was for sure the issue (turbo) that after swapping for another one it would go away, but it hasn't and what's interesting is that the amount of oil being burned/lost/eaten/magically-disappear is the same.

There's a history with Buschur and their engines, I would never say anything bad about you nor your engine building skills and I'm proud to have it in my car (just when I talked to you over the phone to pick up an engine, it was like talking to a legend), it's just the frustration is getting to me at this point, so anything I can try, do, redo is helpful.

 

I didn't know the car was tuned or who had tuned it, wasn't pointing fingers tscompusa. I'm sure you looked at the video and the car is dead rich, wouldn't you agree? I don't know if he's sending datalogs to you with AFR, if his gauge is junk, if the sensor is junk, if it's in the wrong spot, I don't know but we all know that black smoke is fuel, white is water and blue is oil. Makes trouble shooting things easy.

We are not perfect, **** happens, but in this case, two engines using tons of oil is odd and the fact it doesn't have blue smoke with the HUGE oil consumption that it does makes me wonder WTF.

 

David, he got the logs with AFR. It's the AEM UEGO Gauge w/ Sensor, sensor is located at around 1-2 oclock position in the rear of the Downpipe. I just purchased another AEM WBo2 Sensor that I'll verify just in case this one is faulty.

Yes, car pulls a lot better and I'd say smokes less too after Tom's tune, but I sent him the video of it smoking after the tune and I'll send you one over PM too, if you find some free time glancing over it. (WOT doesn't smoke, partial throttle say 60%, early in gear with some boost, that's when most of the smoke shows up)

I'll also continue with my plan of pouring the dye and then taking it apart after shining the UV light at obvious places where oil could be seen (intake & exhaust valves, ports, turbo, intercooler, LICP and UICP) but I wonder if it still leaves a trace when oil is burned.

 

I am not the original tuner. i just now started to tune it as of may 24th. Before i started he sent me that video and i was pretty surprised of the smoke. I did not know this thread even existed until today/last night may 31st. I found it by accident. I noticed it was the same video i seen the other day, so i figured out it was the same car.

Yes looking at the video at first i said it was way too rich. he sent me another vid with my tune and it smokes a bit as well, but then didn't towards the end. so if the aem gauge is going bad they read leaner than the cars doing, so thats definitely a big possibility right there.

i don't mind taking the time to help him resolve as he swaps parts, so that's perfectly ok with me.

i didn't know any history on the car before i started the tune. nothing seemed out of the ordinary during the tuning. engine noise level was normal, car tuned fine. thats why im saying its not your engine or anything to do with your engine.

i made it pretty clear to him at this point. we will go from here and ill have him update thread if we find anything wrong that may have caused the smoke.

 

Great to see tuner, engine builder, and owner coming together to get this sorted out.

 

Tom's been really helpful and we're trying things out but yeah the diesel smoke is almost gone and the piston tops look a lot better though not as sludgy but nice and dry. There is at times during boost what seems like visible puff of blue smoke , i will shoot another vid but the black smoke is almost gone.

Right now waiting on new pcvs and aem wb02 and see if we can get to the bottom of this.

I'd like to thank David and Tom for helping out here , i really appreciate it , puts my mind at ease a little.

Hai Keith !!!

 

Glad to see progress being made and everyone calming down.

 

The insane consumption continues , dry under the car , catch can only seems to have condensation and fuel but not much.I'll do compression tomorrow.

I measured the oil use and in 450 miles of mixed driving , local and highway i had to add 1.5qt and currently am on the half mark between full and low.

I had a friend following me and he said everytime i was getting in boost he'd see blue smoke but not that much followed by little bit of richness and then once that ended, while still WOT. It looks like it's most visible when getting in boost , the first few psi.

 

Buschur, is it common place for a built motor to consume this level of oil? Or is this amount just way more than should be expected?

 

Totally not normal. Maybe a qt or so in 3k hard miles. This one must have a yard nome siphoining some off at nite
