Hey guys, need a little advice here (thanks for all the help so far Dave C.). I just did a fresh rebuild and now have a 007 smoke screen coming out the tail pipe! Here is the story:



I primed the engine... the motor started right up after priming....but had a 4000 rpm idle so I shut it down after 30 seconds... it burned all the assembly lube, excess oil out and then didn't smoke much at all. It took me 4 or 5 starts/stops to figure out the TPS sensor was causing it to idle high...but still barely any run time or smoke. Now after letting it idle for 15 mins or so of chasing gremlins like trying to cure a miss at idle (1200 RPM) and coolant levels are adequate.. the thing started smoking like a champ!! It has me really concerned....it smokes on start up and continues... the higher I rev it the more smoke. The smoke is a greyish color smells a little rich but not much...I suspect oil, too much smoke and not rich enough for it to be fuel. I want to rule out the OMP isn't jammed up squirting lots of oil in....can I just unplug or pull the vacuum line to disable it?



The way I figure it...its either OMP, Turbos or possible Oil rings (yikes) so I want to start with the easiest. I did a compression test, 95 front rotor, 110 rear rotor.



I am really paranoid at this point given the months it took to put together

thanks in advance,



Chris

Chris I think you will get better responses in the engine building forum. I'm forwarding the thread there for you. I personally think that your still burning off the lubes. Maybe something else but i think once the idle is set,( should have no problems getting down to 750k) the fans are fixed and you let it run for a good 30 min the smoke will subside. Anyone have any other ideas or suggestions? Ther engine was ported and Chris was told that the oil control ring overlapped the port some and that he might be expecting the engine to smoke some. Anyone wanna jump in?

if its still got a main cat it can take a while to burn everything off. i would run it in somemore and see if it gets better

No I believe that he has a mid pipe with a muffler welded into it.

fomr teh cases i have seen its turbo most of the time, unless there is somethign wrogn with oil control rings. portign into the oil seal track doesnt make teh car smoke all that much

Thanks for moving it Dave.



I didn't put the mid-pipe in yet but I agree it could possibly be just the assembly goop burning off but my instinct tells me its something else due to the amount of smoke coming out now after the fact that I saw the assembly goop burn off and then it started smoking some time after that.



I really need to be able to put a few miles on it to see if I can just burn it off but I can't seem to get the fans working...I even applied straight 12v from the battery and ground as it shows in the manual but just got some clicking no spin???? What are the odds that both fans burnt out?



Anyone have an answer on how disable the OMP to verify if it is not related to the smoke issue?



Thanks,



Chris

Disconnect the OMP, Its the large connector near the engine hanger bracket that your not using. I might have a pic. Hold on.

This is the OMP connector.

Also, I just remember I have a spair set of fans. If you want them they are yours.

thanks for the pic, I wasn't sure if simply disconnecting the OMP electically would disable oil delivery...I will give it a try.



I may take you up on the fans just to trouble shoot whats up with my set up (when would be a good time to pick up?). I find it hard to believe both fan motors burnt out at the same time... I was able to verify it wasn't my sensor connection since grounding activated the fan relay...just no action at the fans..arrgh.



Thanks again,



Chris
