My girlfriends 02 GTP started ticking shortly after I bought it.... but then the inside of the engine looked like it was full of dirt because of coolant and oil being mixed for so long. After the LIM gaskets were swapped I flushed it with oil and whatever "flush crap, lol" I could do. The ticking was a lifter not pumping up and now 15000 miles later the engine is still quiet. My engine is starting to look more reasonable inside now, and I pulled the fill spout off last oil change to see what I could. I am nearing a clean looking head casting underneath whereas it looked like mud before.

You could swap lifters especially if you have higher mileage while you are in there. Her car only had 70K on it at the time so I didn't bother.

I would do the LIM gaskets before anything. Leave the lifters alone as they are most likely fine. What I WOULD be worried about is the coolant getting into my oil and spinning a rod or main bearing. Would make the lifter tick kinda small potatoes, lol...

Just wash it all down w/ some oil while you are doing the LIM gaskets and give it the 2 oil changes as prescribed in doing this and I'd bet the lifter tick will diminish. My old motor had a bit over 200K on it and never had a lifter replaced.

I see your point at spending the extra $$, but you will be spending more than the $17/lifter if you replace them all. The stock rocker arm bolts are torque-to-yield, which means that if you remove all the rockers to get to the lifters then you are also buying a new set of bolts, and renting the degree torque wrench from a parts store as they require x amount of torque + x amount of degree to be tightened properly.

Then you also have valve cover gaskets and grommets for the bolts to replace.

If you want some different opinions try and get a video and post it here so we can listen to this "tick" and see how bad it really is.

I'm not saying to NOT replace the lifters, but seeing as how most of the 3800's I've heard have some form of lifter tick I'm not sure it's something that I would loose sleep over. Heck, running some Seafoam through the oil about 100 miles before a change may be enough to clean them up and make them quiet again.

I'm sorry to hear about the ticking issue with your vehicle. I see that you are going through with the LIM replacement. Please keep us posted as to if the repair fixed the issue or not. If not, or if you have further questions, please know that I would be happy to assist you in any way I can. Please send me a pm for further assistance. I wish you the best of luck with the repair.
