ok so we're stumped
If it doesn't get faster it will not be a valve/rod/lifter/anything else in the motor as it all moves faster when the car revs up. I duno wtf it could be if it doesnt get faster, loose bolt somewhere? exhaust?
What color smoke? only when in boost? or just worse when in boost? oil looks good? more infoz required.

i would try the lucas oil stabilizer as stated above thats alot easier than pulling the head and if it doesnt work then oh well it was ten bucks.
other than that i trip or call to zfever wouldnt hurt. btw im friends with nathan and used to work on your car alot haha

had a lifter stick on one of my sr's b4, sounds like the same as you have described. i used 1 quart of lucas oil stabilizer and it worked for me. i ran it for for a couple of days and then did a reg. synth. oil change. i would not advise leaving the lucas in there for 3000 miles tho. food for thought b4 you pull the head
You are aware that it is made to be added to your oil and used all of the time. Do you even grasp what that stuff actually does?
If you said something like Marvel Mystery oil, I could agree with not leaving it in there for the entire time, but even that is designed to be used all of the time...
just like lordofthemiasma said, if it doesn't get faster as rpms increase, then it isn't a valve or lifter or anything else like that.
we need a little more info to be any more help
we need a little more info to be any more help
this weekend im gonna take the oil pan off and check the bearings and pull the valve cover and plugs again and check compression and turn it over without the plugs to see what else i can figure out ill give more feed back after ive dont these things and see if we cant get to the bottom of this thanks for all the help so far
k... so, why did you use lucas to free a stuck lifter? did the genius behind the counter at autozone tell you to do that? Also, from what level of genius are you getting the information to not use lucas for a full 3k?

it was my suggestion, and you are entitled to an opinion but being an asshole w/ sarcasm is not doing anything but making you look dumb. i dont advise lucas for the 3k b/c it doesnt need to be in there for that long of a time period(thats my choice), and as far as you agreeing with me i could give a fuck b/c i dont give a fuck who you are and what your o2 is. take it to pm's if you have to further anything

you win the asshole of the year trophy. now shove it up your ass
can we please keep any negativity out of my thread i didnt start this to cause arguments. ill gladly take any suggestions and use my best judgement to figure out a solution to my problems. thanks again
ok ok ok, I'll let you have it, I was a dick about it.
point being this. Lucas is made to increase the viscosity of the oil you are using. Effectively making it more sticky. Because it is thick and because it doesn't contain detergents, it can't free anything that is stuck. The only two things it can do is keep more oil in places where things are loose and increase oil pressure slightly. hydraulics work due to resistance. You can't have flow without resistance, so therefore, the more resistance you have the more pressure you will have with the same amount of flow.
Marvel Mystery oil and Sea Foam are, simply put, just a bottle of detergents. When they get hot, they clean. A stuck lighter or whatever gets stuck because gunk gets in where gunk shouldn't be. It is impossible to remove all of the old oil when you do an oil change, so eventually some of that old oil just turns to gunk and gets in places it shouldn't be. The idea is, the mystery oil breaks up and dissolves that gunk, allowing you to flush that gunk away when you drain the oil. I don't recommend driving around a lot with that mystery oil in there as A) it burns easy, which is why you can put it in a vacuum line and clean your intake and what not with it, as with sea foam. and B) it thins the oil down. Doing the exact opposite that the Lucas does.
Now, with all of that said, I still remain that it isn't a valve or anything as it doesn't A) happen at all of the RPMs and B) doesn't get faster with engine speed. The oil pump, the water pump, the clutch fan, the alternator, the power steering pump, the bearings, the valves, the lifters, the cams, all of that moves faster the faster the engine turns.
So, to the OP, if the noise doesn't get faster then you've got other places you need to look. The information we need first is things like
Does it smoke?
What color is the smoke?
Any recent work done to anything?
When did the noise start?
Describe the noise, we looking at a metal spoon in a big pot or we looking more like a belt in the dryer?
Does it do the noise sitting still just free revving or only while on the road driving?
If you are driving, does it matter what gear you are in?
Start with all of that before you go exploring in parts of the motor you shouldn't be messing with. No offense, but you don't seem to have a whole lot of knowledge when it comes to engine internals. Wouldn't want you do pull it all apart and either not be able to get it back together or worse, break something in the process.
EDIT: holy crap that was a huge post... Cliff notes
apologized.
explained point in regard to lucas and mystery oil
explained point in regard to the noise related to engine speed
layed out questions OP needs to answer before doing any exploitative surgery to car
