C6 2007 Oiling problems????
My C4 race car is toast [ caught on fire ]. I just bought a 2007 C6 with Z51 package. I'm 73 [ almost ] and I thought instead of buying another race car I'd do HPDEs for my race/speed fix. I'll be running 315 30 18 A6s all the way around. I thought I read somewhere that LS 6s have a oiling problem on hard cornering. True or false??? If so will a extra quart of oil be enough for HPDEs or what can I do? Or not run the car???
Or should I run something with less grip. Street tires or maybe Toyo 888s ?????? All info is welcome. |

LS3 was introduced in 2008, which means an '07 with have an LS2. I think a few people have built LS2s that have been surviving on A6s and an Accusump, but I'll let them chime in.

I agree with RX-Ben. But it depends. If you run A6's you will have the potential for a lot of grip. If you run a track with left hand sweepers that will tend to exacerbate the oiling issue. If you are moving from an all out race car to an HPDE car you are probably pretty aggressive on cornering so that will compound the oiling issue. Also rpm. If you shift at 6600-6800 rather than 6000-6200 that will also tend to increase oiling issues. Solutions (from least costly to more costly): Overfill by 1/2 to 1 qt. Use restricted pushrods (Smith Bros. or Trend) - this will somewhat limit oil pooling in heads and not draining back to oil pan for pickup. Install an Accusump To be as safe as you can without installing a dry sump do all of the above. |

For most the over fill by 1 qt seems to take care of the job, and an Accusump will most certainly take care of it. |

I have been using them for the past 6 seasons and have not seen any valve train issues etc. with 80-100hrs on rebuilds. This is obviously just race engines. Thanks, J.R. |
