need some help with an se
whats up guys and gals i recently just lost an 84 gsl with too much to list due to a friend crashing it while he was follwing me in a truck towing a boat i miss my 12a but i just bought a 85 se with suspension mods and an msd ignition it has 15 in panasports and overall is in good shape since i have gotten the car i have installed a dry cell battery and removed some of the emissions crap and a/c yesterday i removed rad. and fan clutch so i could use an elec fan but when i removed the rad i noticed the mounting bracket was all fubared up so i threw in my 84 12a rad they look the same to me? i also have cleaned out the throttle body and used some MMO on the motor to free up some unpleasant deposits in the motor, the motor has 178k and hasnt been rebuilt. i cleaned out the TB cuz i was getting the partial acceleration at crusing speeds i also used some lucas fuel injector cleaner. when i used the mmo i removed a vacume hose and snagged a longer one from another car to put it into the mmo i then started the car and proceeded to keep the car alive by opening up the throttle a little bit with the linkage it smoked up a storm but went away,i did this twice. when i bought the car there was no smoke on start up now after adding some ground wires and hookin up the e fan and radiator the car smokes from the exhaust and the exhaust manifold and gets worse as the car warms up have i some how managed to destroy a motor or did i just clean it out to the point that itremoved some leak causing deposits possibly the coolant o rings or maybe the previous owner did the temperary coolant o ring fix and upon flushing the system of the old coolant i removed some of the leak stop stuff? i need some help and have looked at everything i have removed intake manny and tb and cleaned it and also did the throttle body mod where you reroute the coolant passage from water pump neck back to the block instead of thru TB. some help any is welcome and if anyone has any tips on first time se owners that would be sweet.

What colour smoke?
How much? Does it go away?
I don't know if you answered any of that in you original post, but it was a tad hard to read...
An occasional Capital leter and new line would help

I wouldn't even read the post because of the lack of punctuation. It's just too hard to read one long sentence. Never mind the spelling and grammatical mistakes.

Ok, on your smoke. MMO is a pretty caustic mixture to carbon, which is what makes it so good in your fuel system, but NOT your oil system.
The carbon deposits that an engine develops over time help to create small 'ridges' of smooth, polished carbon where the rings and seals go, in effect, helping to seal the engine even better than new. Over time, these deposits build up to a degree that the seal starts to hit them, which knocks it down, thus keeping a uniform layer of carbon around the Apex Seals, Corner Seals, Side Seals and Oil Control O-rings around the inside of the rotor. When you added the MMO to the intake system (it sounds like you used a whole bottle), it's very likely that the carbon cutting nature of the MMO burned away all of the helpful carbon deposits, and now you have a sparkly clean engine.
Performance will suffer since the car has less compression than before, and your smoking is almost certainly due to oil getting past the Oil Control O-rings on one side of the rotor or the other, and seeping into the intake cycle where vacuum exists. This oil is then drawn into the combustion chambers where it's burned and comes out as bluish-white smoke through the tailpipe.
I know this because I did the same MMO treatment to my car, and now it smokes when it never used to. Been about a year now, and the smoking has gotten ever so slightly less at startup. No other smoking once warmed up, however, which is the ONLY saving grace.
My suggestion to you is to move to 20w-50 motor oil and CHANGE YOUR OIL NOW! Whether you intended it or not, the MMO will get into your oil through the 'cleansing' process, and your oil is part of the problem until you change it. Remember that your OMP is pumping oil into the intake, and this oil is further tainted with MMO. Change your oil, using a slightly heavier composition (20w-50 recommended), and then just drive it as normal. What you'll likely find is that the smoking is worst at startup with cold conditions, and will gradually get less and less as the engine warms up. Let the engine cool off and you're back to smoke.
I'm in this for a year since my MMO in the oil 'treatment' and I wish I'd never done so. Good luck,

thanks longduck thats is what i thought had happened too but i never put MMO in my oil but i do understand how it would contamintate my oil. also my exhaust smells like coolant though so as of right now i am waiting for the car to cool back down to drain degreaser and water to repeat 2 more times. I am also getting some smoke from around the exhaust mannifold any thoughts on that? but i will go and change my oil right now i also had checked coolant and oil for any contamination of oil or coolant and found no signs of anything.

Hey, Brandon; something else to think about since you mentioned the coolant 'smell' (sweet smelling, white smoke)...
The water sealing O-rings may have also had carbon on them, helping to seal the water system, but that's unlikely. Usually, if the water seals are going, you'll know right away because you get steam from the exhaust and you'll develop a coolant leak that you won't be able to find under the hood (because it's inside your engine).
Smoke from around the exhaust manifold may just be the MMO burning off - that stuff is pretty thin, so it seeps down in between gaskets and things and will likely just burn off over time.
Not sure what else to suggest except perhaps to drive it gingerly for awhile and let the carbon build-up again (!). Hard to believe that the carbon helps to seal, but from my experience, adding MMO to my oil during an oil change was the worst thing that I could do. Car ran fine ever since, just smoked during cold-starts.
HTH (not sure),
