Re: I have a question

This is every LS motor with any amount of mileage on it. They all will get some oil in the intake depending on how often it was changed, how it was driven, what oil was used it.

pop it off and clean it out. Make sure your pcv stuff is functioning, and consider running a form of oil catch can.

Re: I have a question

I had figured the PCV valve had something to do with it I have the intake off that's when I realized there were three or four good tablespoons full of oil didn't quite understand the PCV valve as it appears to be pressed into the valve cover as this is my first LS experience as far as a catch can would this be between the PVC valve and the intake

Re: I have a question

There is no actual valve. It is a restricted orifice. For simplicity sake everyone still refers to it as a PCV valve.

Your catch can would go between the valley cover and the intake. From the valley cover to the inlet of the catch can, and from outlet of catch can to intake.

Re: I have a question

Doubt it, its just kind of the nature of the beast. I would make it drivable and keep an eye on oil consumption. Do you have any history on the engine? I ask because they were known to have DOD lifter problems, and if they haven't been changed, you may want to look into doing a DOD delete. Im pretty sure my G8 has the original lifters and has about 130k on it, so I'm just keeping my fingers crossed that evening is going to be fine on it for a while.

I have no real knowledge of the motor other then I heard it run the oil was drained when I got it there was some left in the pan which appeared to be clean and the motor appeared to be taken care of it still has its lifters and I had no immediate plans on changing them with 60,000 miles on it like you I'm hoping they will be OK the DOD was turn off if they become a problem later on I will convert it along with a cam upgrade

Re: I have a question

A PCV valve I believe is basically just a restricted check valve, like Ls1nova said it probably wont make a difference. You wouldnt really gain anything from it.

If you have your DOD disabled through a tune or obd2 device then it should never become a problem. Problems arise from a pin in the lifter getting worn or dirty and getting stuck in the open position, then the lifter will only collapse and never regain its solid status. If you are not moving those pins they shouldnt get stuck open.

This is a really good article to read http://lt1swap.com/afm_delete.htm
