The picture I posted is the only I've see on an ecotec with a plastic valve cover, have yet to see one in a car, or any information on exactly which engines and cars came with that. D you have that information?

How? Can you please show me? The information shown in the thread so far only gives information on finding date of manufacture.

Yes, this is the reason I started the thread. This video and pictures show an '07+ L61 and I need pictures of an LAP/LE8. I need to know if those two have the valve reliefs of the 2.4 or the dish of the L61.

 

In case the above link dies in the future, I am attaching pictures for reading the broadcast code stamping on the oil-filter housing

 

Found an alleged LAF on ebay with a broadcast code that makes no sense.



According to this, It was made in 2011, the 51st month(???), the 49th day(???)

Any suggestions?

 

The "sequence" number identifies the exact vehicle; it is the only part of the VIN that really matters. All of the other parts are just date an factory stuff.
I don't know how to get the RPO from it, but GM service advisors can do it. So, I guess it is easy (those people are pretty dense).

 

Is there a reason all of my replies to my own thread are deleted?

 

I’m not aware of any deletions, I’ll look into it.

they were not deleted, just flagged by our website , I’ll fix that.

There fixed, there was a problem after the Cloudflare site was down a day or two ago. My bad I didn’t see it earlier.

 

I found this photo of an LE8 in the Saturn Sky site
https://www.skyroadster.com/threads/...-build.101567/
but I can’t get it to download , so here’s a link to that site , note the piston tops are dish like relief cups for the valves

 

Here it is Oldblue

 

Yes that one, first I’ve seen the relief cuts for the valves into the dish top piston.

 

No problem, thank you!

Interesting that it's both dished AND has valve reliefs. Where am I missing the part where he says it's an LE8? I don't see it mentioned in that thread.

I'll be going home for thanksgiving, I'll spend a day in the junkyard ripping heads off and taking pictures.
