Just get the motor out and then start working on it. You have to remove the brake booster to just get the cam cover off, but you can remove the motor without removing the brake booster.

Yeah, I realized that when I looked closer at the rear bolts on the driver's side, lol. Now I'm working on disconnecting everything from the engine so I can get it out.

Couple questions:

1. How the heck do you get to the exhaust manifold bolts? I can't even see most of them. It doesn't help that the manifold/cats are one piece.

2. There are a couple wire harnesses that go down to the oil pan on the passenger side. It's very tight in there, can hardly see where they go, how do you get to them to disconnect them?

3. I notice in the service manual it shows some special brackets for lifting the engine. Is there a way to lift the engine without these?

I asked the guy about why the underside of the hood was white. He said he got a new hood because someone with a hitch backed into his and made a big gash in the middle. The new one apparently came white like that.

Till one of the other guys gets to your Q's I'll toss this out fwiw.

1.) I do believe if you remove the wheel well liners you can do the exhaust bolts.

2.) Same as above and the "K" members, two of them at the front of the oil pan can come out I think 16mm wrench &/or sockets. The one on the pass side will reveal the wiring once it's out. The pieces I'm talking about appear to be holding the motor mounts, they don't as the motor mount is actually on an ear on the main frame rail. Just remove the two front 16mm & the rear two 16mm(?) and that bar will come out.

3.) This one I can't answer , but Jeff or one of the FBI can answer that one.

The K brace is correct, three 13MM bolts on the P/S frame rail(one on the top is hard to see but easy to remove)........two 15MM in the front and the the one that attaches to the motor mount. This gives you access to the O2 sensor, harness but unscrewing it would have the same effect. This will not drop the engine if removed.....thanks to Jeffvette for the info last week,


I would assume that the lifting brackets are not required, not sure how a chain could not perform the same function.....but I will let others chime in on that.

Thanks for the replies, guys. I'll remove the wheelwell liners and the K-members (didn't realize you could take those off with the engine still mounted) and see what I got from there.

You can pull the engine out with the manifolds attached. Just need to be careful. I like to pull the plenum and injector housings off to get a little more room and also helps to remove the windshield wiper motor cover.

As far as lifting. You can use the injector housing bolt holes in the head. Use and injector housing bolt with stepped washers.

As far as the harness undo all the electrical connectors and leave the harness in the car, and yes the wire that comes down to the right O2 sensor and crank sensor is tough.

Well, I got both exhaust manifold assemblies off. Removing the lower rear wheelwell covers and both K-members made it a little easier, tho it was still a PITA to get the manifolds off! All the wiring harnesses have been removed from the engine and laid aside also. Engine is about ready to come out now I think.

The plenum is removed, but the injectors are still installed. Jeffvette, you mention using the injector housing bolt holes for lifting. Not sure which holes you mean. A picture or a diagram would help showing how the lift harness connects.

Can you leave the transmission installed, or do you have to completely remove it? When I did my LT1, I left the transmission installed, supported by a jack and removed the engine, bellhousing attached. Don't know if you can do the same thing with the LT5.

Can't stop staring at Jeffvette's avatar... LOL, yummy!

I think that is a picture of Jeff taken last year at BG. I heard that is what he wears under his race suit for good luck. ,
