1988 BMW 325i Base 6 Cyl 2.5L
I own a 1988 BMW 325i when starting it, especially in the morning, it runs real rough, and it smokes.
Once it is warmed up it runs like top. I have only replaced the air intake assembly(hose). The plugs look decent. It has at least 179,000 miles, but the transmission is strong and the engine runs great when warmed.
common: Crank Case Vent Valve + 4 Breather and dip stick Hoses .
