Aight, I left this post hanging for a while. <img src="/forums/images/graemlins/smile.gif" alt="" /> Partly because I am lazy and partly because I wanted to see how the new oil (Mobil 1 5W30 to Mobil 1 10W30) might change my noisy timing chain (assumption) on cold start ups.

Amazingly, the change in oil weight got rid of my timing chain rattle on start up! I am shocked myself. With a slight drop in ambient temps and the heavier oil, I have NO sound at all. This is great because I don't feel the need to break into the timing chain components. I suppose I should pull the oil pan and check things out - but I ain't gonna do it unless I hear some noise.

Some more on oil weight. I haven't told you all that I was running Mobil 1 0W40 before I ran the 5W30. <img src="/forums/images/graemlins/ignore.gif" alt="" /> I am pretty sure (my memory is a bit fuzzy) that the timing chain noise started on this oil. I love the concept of a 0W40 (easy cold starts and protection at high revs and warm engine temps), but I guess it isn't the right oil for these (or my) engines. My 1995 SAAB 900 Turbo runs great on that oil - but that is a different beast. Anyway, I'm a happy camper.

Oh yeah, I have not taken any pics of that mystery connector. Someday! THANKS. <img src="/forums/images/graemlins/patriot.gif" alt="" />
