Ok, so it’s not a manifold issue. Last few weeks, I have been noticing a few drops of oil on my driveway. The car had Castrol GTX regular 5w30 put in Oct. 2004 and the clutch went mid-Nov. 2004 so the car pretty much sat idle in the garage for a few months. After the clutch was fixed, I drove for a bit (put a few hundred KMs with the old oil still) and didn’t change the oil till April 2005. I put in Mobil 1 15w40 synthetic and when I did, I put in a bit more then the recomended 3.8L w/ oil filter (I probablly put in over 4L). I actually drained some over the weekend, yet at work I noticed a couple drops on the pavement. When I did my clutch swap, I replaced the oil seal and made sure to use a crap load of RTV copper sealent (see pics below). So it’s either at the edge of the oil pan or the rear main seal.

Gonad it’s the synthetic oil. Synthetic is a much smaller molicule and will leek past old seals. Changeback to non syn and you will be fine. I had the same prob before. ---

I had the same prob before. I had a feeling it was something like that. But I mean I have run Syn. last year and had no such problem. Why now? Not to mention I even replaced the rear main oil seal which looks like the only other place that would actually cause any other leak (besides the oil pan which I didn’t even touch). The oil I have now is 15w50 (I thought it was 40 but its 50) and I mean it’s obviously a thicker oil. BTW, After I changed from 5w30 to 15w50, the car felt a bit ‘heavier’. Hard to describe but the gas pedal didnt’ feel as ‘soft’ .
