Alright I know this is the place where at least one person can tell me what is wrong with my poor baby ... Now i live in edmonton,alberta canada and a few weeks ago when it was moderately cool around +10 i drove my car for about 20 min and then left it runnin while i ran into a store to grab smoethin...when i came out it sounded like a diesel ... now after a winter oil change and now that its ccooler it still does it but just not as loud... is it my lifters?
