Start Up Noise
Hey Guys, so I have a lexus GS450h that is about to get its engine replaced. We noticed a loud ticking noise and long story short it turns out loose metal was flying around inside the engine and the engine bearings deteriorated.
So I started listening to my N54 e92 more closely and it also has a ticking noise and sounds like its coming from the engine bay. I thought it was a timing belt or something but then realized our cars have timing chains. And at start up the car makes a wierd shriek noise for less than a second and goes away.
Any ideas? Should I be worried? I drive about 50-75miles a day so i need my car to be reliable, hence I have waited so long to do a chip. I finally bought one (still havent installed) but now the car is making noises.
