Question about 1999 BMW 328 Series
SO MY HUSBAND FIGURED OUT IT WAS JUST THE THERMOSTAT WHICH WE REPLACED BUT SHE STILL LOOSES POWER, ITS ALMOST LIKE A LIGHT PULL BUT THEN SHES FINE, EXCEPT 4TH AND 5TH SHE DOESNT HAVE HER KICK IF YOU WOULD SAY NOT AS MUCH GUTS, AND SHE HAD SUM GUTS. I RESEARCHED WHICH IS HOW I FOUND YOU, THAT ITS COULD BE THE VANOS SYSTEM, WHAT DO YOU THINK
The variable valve timing, may have been effected by the over heating.....I'm sure that you're already thinking what I'm thinking.....A change of oil and filter would be a good idea.... I prefer a good quality, fully synthetic oil for high performance engines....
The operation of the variable valve timing is very simple ....The computer opens a valve for either the inlet or both cams, which in turn allows engine oil to be pumped into the camshaft gear assembly and thereby force the valve timing to advance via a sealed and encased viscous coupling.....
If the oil has been damaged by the over heating, that could be the problem....I'd still suggest that you carry out the tests, which I suggested in an earlier communication to you.
Best regards Johngee10
