Okay, my father is doing the Lifter replacement in my GXP and he just pulled the head and found the bad Lifter it was the back banks Lifter on the far right if you were standing in front of the engine. however he said that the ball on the Lifter is pretty banged up. He cannot see any damage on the cam from the Lifter although he is unsure if there is damage from the Lifter not functioning and potentially damaging the cam. On top of that, thanks to 707chance, I received lifters to replace the bad one. Now my dad says the Lifter that is bad does not have a spring on it. The ones I received in the mail did have springs. Is there something wrong with the lifters in my engine or did o order the wrong ones

Pardon any typos on my HTC EVO.

Please help, Any replies will help!

Replace the bad lifter and dod lifters on that bank just to be on the safe side. If the can is OK.

My car is a 2005 and the lifters are out of a 06.

Also, if the Lifter that was bad in the car did not have a spring on it, how can I put a Lifter that has a spring on it in its place?

Sorry can't edit posts on mobile version , but are their separate lifters for the cylinders that shut down. If the Lifter that went bad was a non dod Lifter , I will just buy one from the dealer

Your engine contains both springed units and non-spring units. Don`T panic, give me a few minuites to try an scan the pages to you.. Got to crank up the relic
!

I have no faith the IMG thing is going to work... so here is a backup

Thank you very much for the links. Very informative.

Should I be concerned about the cam?

And, where do you buy a non dod lifter? Everyone online makes you buy 8 at a time. 300 dollars when I only need one!

Roll the engine over by hand ( dampner bolt, clockwise only) examine the cam lobe, it will take 2 full revelotions of crank to inspect the full lobe. Can do with finger on lobe if you can`t see, if you can feel a scratch, groove or any imperfections... you will have to change the cam.
Talk to your dealer, they usually have apack open or they kept the good ones from another job.

Okay....Update.

Unbeknown to my dad because he did not go through the box 707chance had sent non dod lifters in with the dod lifters.

Now, after we examine the cam and hopefully everything is okay we should be okay

Problem is, on the non dod lifter we removed the spacing between the "ball" and the walls next to it is more than the lifters I received from 707chance. His lifters were out of a 06 GXP.

So, my non dod lifter has a larger space between the ball and walls than the other "new" lifters. Almost as if the new one is more precise.

Now I know eaton and delphi both made the lifters , could the 06 ones be the new "revised" lifters?

Hell, How about this Will it be okay to put the next lifters in?

Ill_Born_ss

As long as the Diameter is the same you should have no problem, personally I would swap them so they are the same for all non dod if you can. Yes there was /is a revised set of part#s that was issued at some early point of the LS4. If you can get a close up picture and post it for others to see the difference incase they stumble on this.

The old one is all banged up on the left of both pics. But yes it would seem to help in the oil flow

how the hell did that happen?

hazards280

I honestly have no idea, I started the car about two hours after driving it home (45 min drive) and it was ticking to beat hell. I knew it was a lifter , and come to find out it was collapsed. The bang marks on the lifter are from the cam hitting the button of it when it was "supposed" to be going up and down like lifters do.

Hopefully we are all set and running by tomorrow night.

Thankx for posting the pics.
The open type design actually threw/ displaced to much oil and did not stay secure enough in the bore, hence the full collar design.
Before you completely assemble everything, remove your oil pressure sensor and under it there is a small last chance filter, pop it out and clean it... all oil to your lifters must pass thru it first.

Thats some pretty nasty looking carnage. I wonder what happened to the pieces, of the lifter?
My lifters looked perfect except for the fact that my DOD lifter spring was compressed and is stuck. I had metal dust all over the lifter guide and pushrod. I ended up replacing all of my lifters just to be on the safe side. I used the noisy *** G8, DOD versions made by Eaton 12569256. Eaton,s have three slots in the top piece. I should have bought the Delphi versions which have two slots.

hazards280

That's what I was thinking, I believe it is from the cam hitting the dead lifter that caused the markings on it. The lifters that are going in now, must be Delphi's as they only have two slots. If I didn't want to keep DOD, I could have done some serious mods while I was this far into the engine.

I would like to thank everyone for all their help as well.

Great News Everyone!!!

Car is done~ It's running great and sound better than ever. The lifters ticked for about a minute at start up and that was it.

Throughout the whole lifter replacement most everything went okay, only BAD thing that happened was.....in that "access whole to the cam under the DOD panel. A bolt dropped in....

No Joke.

I heard it hit the bottom of the oil pan, so guess who had to pull the oil pan to get the bolt out. 12 hours later after having to pull the cradle under the engine and....well ....just plain hell! I retrieved the bolt.

Everything is okay and car is running great. Only alert on in the car is to service the variable steering or whatever however im sure it will go away as soon as the air gets out of the power steering as we had to refill that and other fluids.

I also went and installed a Optima Red Top battery for it as the battery that was in it did not have enough CCA for the car on cold mornings. Mind you I bought the car from Kentucky, so it was warmer than Michigan.

Car fires right up and sounds AMAZING. Aztek is parked!!!!

This is great to hear, and you guys got it done pretty fast too. You'll be a pro at a cam swap. So start planning!
