2009 HHR needing new piston rings here I located some though need them ASAP not over a week wait what types and measurements of rings on this one is any can give me the know on it with links, preferably Amazon search link.

New rings measurements depend on the bore of the sleeve . Sometimes you need to have the sleeve bored slightly at a machine shop.

you have a 2009, which engine displacement? 2.2?2.4? 2.0?

Not sure what you are asking. You don’t state which engine you have. There are 3 different engine sizes in the HHR line.
Stock rings are usually purchased in a major engine overhaul kit. Why are you asking for rings only ?

Try asking at a local machine shop.

Stock sized rings might do it , but after the wear and a good honing, you might need oversized rings.

You are doing the rings on this engine and don't know what you need?

2.2L if any mechanics here can say yeah those will work absolutely that would be cool cause I found these with search on Amazon.com and want to be sure before breaking down the engine and ordering pretty much I work on motorcycles and this being first car engine I’m digging into so am glad it’s a Ecotech!
If anyone can Amazon search these to confirm cause they don’t SAY HHR I know total noob question though don’t wanna drive it distances that I been relying on it as is only ride at this time.

DNJ PR405 Piston Rings/For 83-02 Kia, Mazda, Ford/ 2.0L-2.2L/ L4/ DOHC, SOHC/Naturally Aspirated, Turbocharged

or more likely the

DNJ PR328 Piston Ring Set Standard Size for 87-03 Chevrolet, GMC, Isuzu 2.0L-2.2L L4 OHV Naturally Aspirated

it’s at 2.2L and from what I seen the bearings should still be in good shape from inspections I had seen in online videos though checking on that while replacement if so needed takes place. Installing new shock system and catalytic converter which be delivered Friday Originally Was running in idle “strangely” aka uneven rhythm and lights dimming so added seafoam and immediately almost fixed that which surprised Me though will be doing the pressure test in a few hours as still lacking HP it feels while on highway. Cleaned engine grime and there are no signs of blown gasket through oil and coolant levels or visible. The 2009 HHR It’s got almost 300.000 and the transmission good at this time yet don’t have repair list from previous owner as if it matters at this time for anything other than ring replacement or chain I guess.
Just removed Everything interior yesterday other than driver seat and is sailing 🤘🏻 stoked about getting fully straight this engine so any part reference is great!


Also can anyone give me the scoop on oversized rings Vs. Standard fit as mentioned. Like I can search 2.2L engine and any of them will do?

Oldblue

Oversized rings depend on actual measurements of the bores, all 4.

the rings you mentioned are for other brands and older 2003 Ecotecs

are you sure the Seafoam didn’t just clear up stuck rings?

FYI. You can’t order rings until you tear down the engine and see what you’ll need. The bores will need to be mic’d and inspected. Then you’ll know what needs to be done. If it needs boring( not sure if you can bore an Ecotech) then you’ll need oversized pistons/rings.
If you tear it down that far, you need to inspect the crankshaft and replace all the crank and rod bearings.
Not a job for a novice.
Most folks opt for a new long block or get a used engine.
