What did you do to your G8 today?

[JVH1982]

Drained out the Royal Purple 5w30 and refilled with Syntec 5w30 in the hopes that some of the valve train noise would go away. Since taking off the Magnaflows for the winter and putting the stockers on I have heard much more of the engine. I don't like what I hear ;-(

I will leave it for a few days then try 5w40 to see what that does. If nothing, I'll have to live with it I guess.

Also vacuumed it out, cleaned the weathertechs, and wiped off the touchless car wash haze.

Mine is the same way. I have axle-back deletes and I can still hear the valve train. It brought me no comfort, but maybe it will do you some good: from my mechanic to the tuner, everyone says these cars have naturally noisy valve trains. Bleh...

Mine got many times worse after I changed the cam and did the DOD delete. I really didn't notice it before the cam. But now I'm ALMOST embarrassed to start the car with car enthusiasts around...sounds like I've been neglecting it ;-(

I'm on my second set of factory lifters and they're (one at least) already starting to sound bad. Especially on a cold start at the end of a work day, It definitely takes away from the nice sound coming out the back end.

Any one have a video of this? I can hear a noise but I think it may be pcv or something.

PCV would be a hissing or whistling from the moving of air. Lifters would be a ticking or squeaking.

I'll catch a vid this week. More noticeable with engine cover off. Injector maybe?

I've got this ( questionable tick)

If you would, start a new thread about it so people can comment and properly get a focused discussion going without crowding this thread.


As for the OP, yesterday I got my Pedders SuperCar coilovers installed, and today I drove it!

Removed the Pontiac arrow from the back no gouges and such first step in rebaging!

I tried some new oil at my last oil change. I usually use synthetic stock weight, what ever is on sale or AMSOIL for the 1st 50,000 miles. Now I have 84,000 miles, hard miles. It always had a rough sound valve train and I get the cold start lifter tap pretty bad if: it is winter or cold, if even just a little bit low of oil-even 1/3 of a quart low will make it louder, if it is even slightly dirty, usually it will start tapping after 3000 miles of oil use. A very respected buddy of mine suggested this newer type oil made especially for older cars with some milage. It is only a BLEND not full synthetic so it was much cheaper and I got it on sale at 3 bucks a quart!!! It is called DEFY, it is made by QUAKER STATE. http://www.quakerstate.com/#/motor-oil/defy

They say, "Quaker State Defy™ Synthetic Blend Motor Oil
Help virtually stop the aging process inside your engine.
Over time, all engines age and experience wear that could severely shorten engine life. Now there is a motor oil that can virtually stop wear in its tracks—new Quaker State Defy™ motor oil. Quaker State Defy is a synthetic blend motor oil that’s engineered to defy time by preventing 98% of future engine wear1—including camshaft wear and bearing wear. Quaker State Defy contains increased zinc anti-wear agents that target high-temperature and high-wear surfaces to help you get the most life out of your engine."
I really like it. Since putting it in I have noticed way less vavle train noise and as of yet(3300 miles) has not had the nasty cold start tap plus I gained back the 1 mpg I loss since using PEAK SYNTHETIC oil which I had 18 free quarts. Not bad for free but I would not buy that stuff.
The DEFY will be my new go to oil. I change my oil by color, not time or miles. It never gets black, I change when brown and starting to turn black. Usually 3,000 to 9,000 miles, depends on alot of variables obviously. Try it let me know what you think. DEFY I like it.

I did some rewiring on my AFR system. Slowly but surely getting ready for Darlington....
