Ok so I thought I bought an LQ4...here is the original ebay link

http://cgi.ebay.com/ebaymotors/ws/eB...9998%26fvi%3D1

The auction title says Avanlanche/Escalade, the description says 2005 Silverado.....

The paperwork that came with the engine says Escalade Vin N....

Looks like it's an LQ9, how can I be sure? If it is that would be sweet!!

 

Oh...the engine pictured in the auction is not the one I received - flexplates are different...

 

Wouldn't the 6.0L Silverado 2500 engine have been bolted to a 4L80E? Which means it would have a flexplate with 6 bolt holes in it?

Which means that since mine only has 3 bolt holes, it would have come from something with a 4L60E or 4L65E, which means Silverado SS or Escalade, which means LQ9?

 

Just keep talking to yourself - I'll sit back and listen

Not that I know, but there has to be something external to tell the two apart - the GM employees would get them confused if they didn't.

 

if you have the engine there take a spark plug out and put it at TDC on that cylinder and take a flash light and look in at the piston and see if its flat top or dished.

the passenger side engine cover resembles that of a SS

 

Just send me the ECM, I'll tell you what it is.

 

BTW I don't think any LQ4 came with the three piece engine cover. But I may be way off on that.

 

Sounds like an LQ9. Do like Fogle says and pull a plug and get your pinky in there to check the piston.

 

what about the Denali's? That would be an LQ4 with a 4L65... so there still isn't anyway to know, stick yo finger in it and check it out, it's kinda like checking your ole lady's oil

 

did the SS trucks come with LQ4 or LQ9? i believe thats out of a SS.

i know its hard to see but look at the passenger cover near the oil fill tube. looks the same as the ss



heres the escalade engine
