Hi, I'm looking for pictures of the LE8 with the head off. I'm deep in research creating a wiki for ecotec engines, and I have a suspicion the LE8 is the updated sand-cast reinforced block design also featured in the LEA/LAF/LDK/LHU. I haven't been able to 100% verify if the LE8/LE9 are sand-cast or not.

Also, any pics of the pistons would be helpful too. Also any pics of the LE9 with the head off for 100% verification would be nice.

Can anybody help me with some pics, please? Thank you.

 

LE9 ……

I reference this tutorial often.

 

?

There's already a wiki...
https://en.wikipedia.org/wiki/GM_Ecotec_engine#

Sounds like yours may be more detailed, but the information about casting may be in there.

 

It is. Some years were lost foam some sand

 

Yeah, I saw this. It says LE5/LE9, but doesn't say exactly what engine is shown. It is theoretically the LE9, because the LE5 is open deck. But I really need positive confirmation.

There are a lot of things on forums that people say that I've researched and confirmed to be totally false, so I've been really exhaustive in terms of needing as much proof as possible on these kinds of things.

Yes, the Wikipedia has been a great resource. I've mostly been cross referencing between this, RockAuto, Ebay listing pictures, and Car-Part. There are some things I've found on the Wikipedia though that wrong, and some that are outdated. It does not talk about the LE8 or LE9 being sand-cast, and nowhere on there does it talk about the "Gen 3" sand-cast block now being closed-deck.

Yeah, this is a problem. I've seen online that at least one person out there has a foam-cast LDK. I'm really trying to nail down exactly what years of each engine is foam vs sand. Also need solid confirmation that LE8 and LE9 are closed-deck

 

There was a GM pdf years ago that listed manufacturing processes, but before the LE 9 , which isn’t much different from the LNF or LE5 or LE8 or the L61 blocks , it’s the cylinder sleeve diameter that sets the engines cc size . The designation indicates the engines accessory list and configuration. LNF was the turbo charger. LSJ had the Eaton M62 supercharger, LE5 was NA 2400 cc L61 was 2200 cc and so on.

 

On this topic, is there any definitive way to differentiate LAP, LE8, LE5, LE9 from each other externally? Casting numbers or something? I know throttle bodies, intake manifolds, and possibly injectors, but if you get an engine without those things is there any way to tell?

This is another reason I need a picture of a short block, to see if the 2.2 pistons have a dish or just valve reliefs.

 

Who'd a thunk it? Stuff on the interwebs can be false. Even Facebook and Reddit?

 

Hate to be that guy, but considering the topic of this thread, LSJ is supercharged, LDK is turbo. 😬

 

If the paper broadcast label is still on the front end it has a partial VIN that can be used to get a RPO list.
The "book" claims that the VIN is etched near the oil filter. I have never seen it.
