Here is itRe: E90 engine oil leak experience
Hi All,
I've come over from Japanese car ownership and I was wondering if there are lower temperature thermostats available for BMW cars to allow them to run at lower temperatures? Many Japanese after market brands offer such lower temperature thermostats for Japanese cars. I figure that these failing gaskets could be due to high running temperatures of the continental engines in our hot climate and urban driving conditions.
Just my thoughts. Cheers.
