Dealer said the misfire is probably from a bad lifter. Not sure if this is even a dod lifter? Injector was okay. Master tech said the ticking is probably a lifter.

How long can I drive it like this and not do any more damage? Not sure when I can get this looked at. Trying to call a few shops to get a dod delete with a stock LS3 cam.

Any rough costs from a shop??

The more you run it, the more the damage. Stop now, a cam and lifters (if it's the problem). Keep running, getting closer to pulling the engine once all the shavings are scattered around. Keg is half empty on this one.

Hello everyone I am new to the group but I have owned two g8gt's. I had one tapping before and I put a new oil filter and filled it with transmission fluid and poured the rest in the engine oil. It stopped tapping after a few minutes. I drove it like that for 2 or 300 miles. I then drained it and filled it with Mobil one full synthetic and a quart of Lucas and every oil change after that. I just ordered my second Dod delete kit Texas Speed. The first one was for my 08 Tahoe and the second one is for my G8

If the tick is a lifter, it's the wheel or it's starting to rotate in the bucket. No elixir will cure it.

That is true and the only repair for that is to disassemble the engine and replace the parts. It could also be a dirty lifter and that elixir will clean it. Never know until you try it.

I talked to a local shop and he says it quite possibly be a broken valve spring on the 8th cylinder. Easy enough to pull the valve cover and look. Sound reasonable?

You have nothing to lose, its all money now.
If its a broken spring its a win, for now.
