Well since my motor build, there is about 5k on the car. I was consuming oil when I was running 10w30. I switched to 10w40 now, thinking that would solve the problem. I had to put 1.5 quarts in it yesterday. The car hasnt been tuned yet though. Will a tune help me out with this problem? Mods are in my sig. Thanks for any help/input on this subject.

for the first 500 miles I ran regualar non synthetic 10w30. The block was honed, cleaned, new bearings and I put new piston rings in it. After 500 miles I switched to Mobile 1 10w30. Now I am running Castrol syntech 10w40.

 

Maybe the rings didn't seat right. Have you done a compression/leakdown test on it?

 

not yet...Guess I will have to try that.....

 

anyone else???

 

What's your PCV situation? I was sucking it down to the tune of 1qt. per 2000 miles. I then purchased the $37 GM upgrade kit which relocates the pick up to the front with a new valley cover and I don't add a drop in between changes now. I think the F body got the upgrade as stock in '01. Hope that helps.

 

Did you take out your PVC system, if so it can consume some oil, maybe look into a catch can or a metco breather filter. I would try those first.

 

Well I deleted the PCV. I got the breather for the oil cap, and put a small breather on the drivers side valve cover where the PVC goes in, then capped up all the rest of the lines that come out of the valve cover, intake.

 

I got this:

 

Mine is drinking oil due to some head sealing issues. I popped my intake off to check out the intake valves and had oil sitting on them. Some pics are in this thread. https://ls1tech.com/forums/generation-iii-internal-engine/496219-darts-worth-600-more-than-tsp-s-ls6-heads.html

I just want you to be able to rule out the top end of the motor. Good luck!

thanks for the info.....

 

What is this $37 GM upgrade kit?? Got a part number? Will it work on my 01 HD 6.0 as well?

 

yeah, I am curious about that too......

 

I beleive he's talking about the LS6 PCV conversion. With the LS6 conversion the pick up will be in the front of the valley cover.

 

The part # for the new valley cover with the PCV pick up in the front of the motor is #12568002. I paid $37, it is apparently around $45 now. You will still need the hoses however. I have a list of part numbers that I ordered at the same time. I don't remember anymore which is which, this was 4 years ago. Good luck.

well I am going to try regular non synthetic oil, see if that helps my problem. I didnt get to do a compression test this past weekend, death in the family
