The extra fuel helps keep internal cyl temps lower. Thats why as you lean out your a/f ratio, your engine and water temps go up! burns better and hotter. Also, what type of ECU/engine management are you using? does it have a F/I tune on it? pundit 07-30-2007, 02:47 PM i have a build zetec for boost but i 'm breking in the engine with out the turbo and is smoking a bit black why can some help me sorry for the speeling If you are running a forced induction tune without the turbo it will do that. The tune has been made richer for the turbo. If the turbo is not on, it does not require as much fuel, and will therefore produce a "little" black smoke. If you are seeing a lot of smoke you may need to investigate further. Damage 07-30-2007, 05:39 PM If you are running a turbo tune. You may also be fouling the plugs due to a rich condition. May want to take a look at them. 1turbofocus 07-30-2007, 07:41 PM Even if your running a "turbo tune" in cruise or moderate part throttle you should NEVER see black smoke On a new engine you DO NOT want a rich condition fuel is abrasive and can cause the rings to not seat properly. New engine , old engine you want a crooect and proper AF ratio all the time You need to contact your tuner and have him do some adjustments before other issues show up Tom FOCUS ZTS 07-30-2007, 07:57 PM Exactly what i was thinking, when i blew my eng and got a build one with my turbo setup i just broke it in with the turbo but i just never boosted. Just took it easy and everything is fine. That was 3-4 years back, and not prob (knock on wood). P.S. Tom how would I know if i need a new ring? 03OrangeSVT 07-30-2007, 08:06 PM Also you need to consider what kind of oil you are running.... you should NOT run synthetic oil during breaking, if you do it'll never seat the rings properly. FOCUS ZTS 07-30-2007, 08:26 PM What if they did use synthetic when braking, how bad is that? jrpasmo 07-30-2007, 10:20 PM P.S. Tom how would I know if i need a new ring? Eating oil...loss of compression.... FOCUS ZTS 07-30-2007, 10:32 PM how savvier will the eating of oil be? B/c there is some oil burning but i don't think its the turbo. 1turbofocus 07-31-2007, 06:16 AM P.S. Tom how would I know if i need a new ring? Eating oil...loss of compression.... Do a compression test and/or a leak down test Tom | |
