Primary chain noise at start up? AND brake issue! Help!
Hi. I have a 2000 Vanden Plas, and when the car is started, the engine is quiet. However, if I rev the engine to about 2700rpms before the coolant temperature gauge is in the center, the engine makes a loud noise that sounds like it is coming from a lower part of the engine. When the engine is warmed up, the sound goes away completely. Does this sound like a primary chain noise? I have had my secondary chains replaced. I haven't had an oil change for about a year, as I have only driven my car about 4k miles in the past year. Could an oil change give more oil pressure to the primary guides and cause the noise to go away?
Also, my brake pedal is becoming progressively softer. Do the master cylinders of these cars fail much?
