To do so, please send an email to [email protected] with ATTN: sd3433/Cadillac Forums in the subject line.Hello, This is my 1st Post, sorry for my english first of all, im from Europe/Germany.
I have bought a ATS-V from 2017 with defective/faulty engine. The crankshaft had a heavy rod knock. I got the car with completely dismantled engine and have never assembled an LF4 engine before.
Installed new crankshaft, connecting rods, bearings, oil cooler, Head gaskets, piston Rings, valve seals and and..
Now im getting directly after start really ugly white smoke from exhaust.. thought First it can be remains in exhaust, but after Test drive with Bad throttle response + misfires i have stopped, cannot Drive and Start anymore because the smoke is so much that neighboors Are angry, cannot make a test run in my Garage because it’s within 30 seconds full with smoke 😬 there is no fault at the PCM/ECM, the engine runs on idle Fine w/o noises and w/o misfire .. the smoke continues Many minutes after stoping engine 🤷♂️
what can be my mistake ? A wrong "mis"mixed/matched line or Hose ? I assume a Bad fuel injector? There Are no Parts for that engine in Europe so i cannot change Parts so easy and quick.
Have builded up Many German Engines AMG/M5 M6 , v6,v8,v10,v12 or LS1,LS2,LS7,LS9 , 5.7/6.1/6.4 hemi srt but the intercooling and piping system of the LF4 is new area for me , because i didnt dismantled it..
Thanks in advance for all advises and tips.
