ORIGINAL: Texas Bird I will say Thanks to Manybrews. Admittedly, I do need to acquire more knowledge about the vehicle. Who would have thought an 07 anything would have had mechanical followers or pieces that would cause any valve train noise. I will say this valve train noise was at rest, at idle. I do need to learn about MIVEC. Interesting. its a wonderful thing. Its nearly identical in operation to hondas VTEC. You have multiple cam lobes, with multiple cam followers... but only one is activated at a time depending on engine RPM, temp, etc.etc. You have a small lobe for smooth idle and decent low end torque, and then a large lobe for a much higher upper RPM output. If you ran the car on the "big" lobes all the time, it would barely idle. try this.. maybe it will help. http://en.wikipedia.org/wiki/MIVEC quote:
As far as the transaxle. I do hate to say I'm right. We had it back to the dealer with about 300 miles on the car and they said they couldn 't hear it either. Till they brought another brand new V6 stick up beside it and listened. I'm no genius, I just try to pay attention. Fact is that it's getting worse as time goes. I'll ride the warranty on this and have it tended to before it goes out. Im not saying that something couldnt be wrong, but I will say this.. Aisin (used to be known as Aisin-Warner) makes the BEST transmissions on the planet, bar none. They also make MORE transmissions than anyone else on the planet. Its a company thats majority stake is owned by Toyota, and those are the only transmissions that Toyota uses (the 6 speed in question here is not just used in an eclipse). The fact that the trans makes some noise may be of concern, but I frankly wouldnt worry too much about it. As you know, you do have a 100k warranty provided you keep your maintenence up to date. quote:
The smoke I saw at start-up. It was oil smoke. Is the car burning oil? No. Just curious that you would see that. Yes, it could have been moisture, but it wasn't. I've seen it 3 or 4 times now. As far as your take on synthetic oil that's far too long a subject for me. I'll tell you that I agree with you in parts and disagree in others. I used to work in a unit that made PAO base stock(poly alpha-olefin). When it got on your hands you could wash them 3 times and still fell the slick on your hands. Amazing stuff. I do own a Ford 302 with close to 300,000 miles on it since the rebuild and have run nothing but natural petroleum based oil in it. I have 204,000 miles on a completely original 1993 diamante, whose engine is a direct decendant of the 3.8 in your eclipse. Its never seen anything but normal dino oil, every 3000-4000 miles. Traditionally, those 3.0 liters DID start burning oil around 150k due to worn valve seals/guides, but that problem was pretty much eliminated a decade ago due to improvements in seal material, guide material, oil, etc. The problem was much, much worse when oil changes were neglected. My Diamante burns about a quart every 1500 miles, which is actually allowed on a NEW car from pretty much every manufacturer. quote:
I do admire your loyalty to the brand. And not sure about the characteristic thing. I was raised on Chryslers, but now have latent Ford tendencies. My first car was given to me in 1973 when I was 13 and was a Valiant with the mighty Slant 6. I worked on some of the first Mitsubishi autos in this country as I worked as a mechanic for Chrysler in late 79 and 80. The Chrysler fours were junk. If you wanted a good vehicle in that arena you bought the Chrysler product with the Mitsubishi engine or you bought the whole vehicle that was a re-branded Mitsubishi. You should have seen the crowd of mechanics around that new tech front wheel drive in the dealership wondering how to get the transaxle out of it on a warranty job. Bird trust me, I still see that kinda thing. you shouldnt worry too much about your eclipse.. they're well built. Will it be 100 percent trouble free? Probably not. But out of the 39 cars Ive owned, none of them have been.
