Another slow GT
This all started when I picked the car up a few months ago and performed the first oil change. At about 120,000, I drained the oil and from the pan and filter, pulled maybe 2.5 qts of oil. That may sound horrifying, but it confused me more than anything due to the lack of any noticeable signs of oil loss. I tend to run my car pretty hard and mixing that with low oil is just a bad combination, to say the least. Anyway, changed the oil and added maybe 5 qts. Well, the next time I changed the oil the same happened again, only pulled 2 or 3 qts. Mind you, I haven't gone over 3000 miles between changes, more often it has been closer to 2800 miles. I eventually began to add 6 qts after reading about the size of the oil pan and learning that the pan could handle it with no ill effects; I figured it was good insurance for hotrodding around. The car has NEVER left a drip of oil wherever its been parked. No parts of the undercarriage are wet in oil and no blue or white smoke has EVER come from the exhaust. I've also never smelled any oil burning. Since then, I've been adding oil every now and then, maybe a quart every 1000 miles or so, maybe more. I took a look in the valley today and noticed a shiny, possibly wet film beneath the intake manifold. Since its been dry lately, I'm assuming its some fresh fluid. Anyway, I'm dumbfounded. No signs of burning oil and no signs of a major leak, yet it would seem that I'm losing A LOT of oil. Does anybody have any ideas? I'm at a complete loss. Thanks in advance for the replies, you guys are great.
