Hello all , I am new to the Maserati Forum. I have owned my 89 430 since 1999 and I have kept it in wonderful shape ,and over the years it developed a leaky cam seal. Of course it dripped onto the exhaust causing extreme fire danger. my grandfather is an engineer and we decided to replace the seal ourselves. After extensive study of the factory service manuals and extreme care while performing the operation the car will not fire up. We took extreme care while timing the engine fearing valve-piston clash. the car will act like it wants to run and sometimes backfire lightly. Could my timing of the distributor be 180 out ? Anyone who can help please feel free to bounce any ideas off of me.
