I havent had time to take my valve covers off but just from this can someone give me some ideas of what to look for as for whats causing the noise?

I noticed it a while back when i was out cruisin around, i spun the engine up to about 5900-6000 rpm and i noticed it the first time. Then today i went to pass someone on the highway and i went up to roughly 4500 rpm and it did it again only this time it seemed more severe/more frequently.

I dont think this is a metal on metal sound although if its in the engine somewhere its probably muffled a little. I have no misses or exhaust leaks, no codes, oil pressure/ coolent temp is normal. Today there seemed to be a random and hardly noticable tick at idle after i got home.

i have just under 20k miles on the engine, lifters, and all other parts in sig

I found some chunks of a tiny spring.... Or it's metal that's been twisted up, under my driver side valve cover

Anyone know what that is from?

I'm at a bit of a loss. Its too small a diameter to be a wadded up valvespring, it doesn't seem to be bearing shrapnel, and it seems to large to be anything from the bottom end that could've been pumped up to the valvecover.

I hope those are not partial piston rings but they don't appear to be that either

I hope someone else can chime in and help you out

Have you tried draining the oil and checking for shrapnel in the drain pain? That can tell a lot.

It's hard to tell the scale without a reference but those look like the kind of springs that are on lip seals. Did you get a look at your valve guide seals to see if the springs are missing? What kind of valve springs do you have? Do they have a flat damper? Sometimes when the damper breaks it chews up the valve guide seals.

Link to springs kit that I have is in my sig.. The mechanic that built my tranny asked me about my car smoking on start up and he said it kinda acted like valve seal problems... Said it wasnt a big deal as long as i checked my oil and didnt mind burning some...

Burns about half a quart a week ~350 miles a week

Good catch guppy, that is exactly what those springs appear to be. Now he's got to catalog all the places those could've come from. But yes, valve guide seals seem quite likely.

They were sitting in the driver side oil returns sooo... Driver side seals are bad... Lol

Alright sorry for the long delay, i got a new job working over 60 hrs a week lol. I figured out the popping noise. i have a shelled out valve spring dampner on the passenger side. 3rd spring back front the front of the engine to be exact. The spring itself is still intact but there isnt anything left of the dampner, think I should check things out under the head or should it be ok?

Now with the springs having 18-20 thousand miles on them i think i should get a whole new set of springs/components/valve seals (not sure what spring to get). If i get new springs I'm most likely going to get a double spring and switch out my 1.5 roller rockers for 1.6 ratio NSA 7/16s stud rockers.

can i do this all with the heads on the engine in the car?
any spring recommendations for cam in sig+ 1.6 roller rockers?

Looks like it could be a oil ring

im 99% sure its a spring dampner

Are you looking for single with Damper, beehive or dual?

Single W/Damper. PAC-1201
Beehive. PAC-1218X or 1219X
Dual. PAC-1206X

that really looks like valve seal springs.

Glad you found the problem but you might want to look over the entire valve train for issues. Check for coil bind and the retainer hitting the valve seals while you are at it

its either part of a valvespring seal or part of the rear main seal but i dont see how that wouldve gotten up on the top end of the motor

If it is a valve spring seal then as stated you should really look into the entire valvetrain. Start by taking the springs off and measuring valve guide play. When a valve seal goes it could mean more serious problems are starting.

i know the valve seal springs are gone on drivers and pass sides, so they all need replaced. i hope my heads arent ruined or need to be reworked, i cant imagine there was a machining issue the machinist that did all the work on the engine is very competent... although i suppose there is always a dud in the group.

all the other valve springs are in one piece.

Definitely check valve guide clearance. If you just put seals back on you might be trying to put a band aide on a severed artery.
