Nevertheless, my engine consume up to 1 quart of oil each 650 miles in spite of all new parts (pistons, liners, rings, valve steam seals etc.). It was correctly broken in and I run it with semi-synthetic Mobil oil 10W-40. It's not as the consumption would disturb me much because the engine really pull strong and run on german highways a topspeed of +200 miles. I am just curious to know what experiences about oil consumption other cast iron sleeves LT5 owners did. Sam |

Re: Secondchance - 380 build begins!
Not at all.
My car only smoke a bit black when accelerate fast. While my engine was stock it also didn't use much oil with about 100'000 miles on the clock. I think engines with iron sleeves like to take a bit oil. I spoke with some C6 Z06 owners and they told me their engines also take about 1/2 till 1 quart of all each 650 Miles. |

Re: Secondchance - 380 build begins!
Once my car is completed I will share my result from oil consumption perspective. In general, if you are not burning nor leaking oil and yet see oil consumption suspicion is being blown out through the PCV system. Perhaps one of the LT5 gurus will chime in.

Look for a thread here where one of the members had oil consumption issues that were significantly improved w a more accurate tune/calibration. You mention black smoke when getting "on it". Too rich, maybe washing the oil off the liners?

The compression on all cylinders is also absolutely equal. It would be really interesting to share with other owners their oil consumption experiences. Sam |
