help me my idiot thread
 
Well okay my car still puffs white smoke on startup huge thick for about 2 minutes if I drive it i let it sit who knows how long. I live in massachusetts and its kind of cold now in the mornings. I check my coolant 3 times a day fluids are good so I would think my coolant seals are good.

I have no idea what it could be can anyone give me some ideas. Personally i don't mind the thick white smoke show on startup but i think the neighbors want to kill me and so do people behind me. I don't know if it would matter but i still have 5w30 oil in the car even though its coold didn't hit over 1k yet to do another change. but i already did have to add 2 quarts.

thanks in advance.

If your car isn't drinking coolant, then it's probably just condensation built up in the cat. Burned coolant has a sweet, plastic smell to it.

Are you sure the smoke is white? Sometimes the car will smoke on startup due to a phenomenom known as "blow-by" which is essentially oil being sucked into the intake. If this is excessive, it could be that your turbos are shot. One way to tell is by pulling the hose off the bottom of the intercooler and jack up the front of the car. If oil pours out of the intercooler, then you know you have the aforementioned problem.

Not all together true.....................

The oil fill tube have a vent hose that is connected to the primary turbo intake elbow.

You can "suck" quite a bit of oil into the intake. I installed a oil catch can & was surprised at the amount of oil after just one session of lapping at the track.

Prior to that I thought my turbo seal were going. I removed the throttle body elbow & oil dripped out of it.

I cleaned out all the tubing from the turbo & flushed out my PFS intercooler with solvent. Installed the catch can & did another lapping event.

All clear...........

You did mention you added 2 qts. of oil. How many miles in between? You might have a oil seal leaking. I would ask Pineapple, Petit or KDR what troubleshooting methods they recommend to verify this.

In the interim I would remove all the tubing & clean it. Flush out your intercooler. Disconnect the breather line from the oil filler neck. Drive around for a week & see if you still get oil in the intake. You CAN put a filter on the oil breather line you disconnected or install a oil catch can.

Unless the hose is lying in the dirt I don't think it's gonna hurt to let it vent to the atmosphere. it's only temporary. If he still has oil in the intake he has bigger problems anyway. Im sure im gonna here it from all you guys............

get a coolant system pressure check, then check out your turbos for excess shaft play or *excess* oil in the intake piping, then compression check.

by the time your done with these you will know the exact health level of your engine :)

In my case, the turbo back pipe was bent from an accident by the previous owner. That bastard didnt even fix it, so after driving, some of the oil would eventually "stuck" on that pipe.

Turns out that when I cold start the engine, the stucked oil would be under high pressure in that turbo-back pipe which cause it to burn and exiting tru the exhaust pipe.

But then again, it was oil smoke...not the kind of coolant "sweet" smell.

Hope that help.

P.S. I might be wrong too...Just something my mechanic told me.
