3.8 rear spark plug issue

the header bolts hold them in.

How come you have so many 3800 cars and yet you don't know that the engine pull brackets are NOT attached to the manifolds?

Seriously.

The misinformation is really getting my last nerve.

The front one is bolted to the cylinder head along with the rear one. The Exhaust manifold studs are tiny...and they sure don't have enough strength to be chained up and use to pull out a 500lb. cast iron pushrod motor.

I just removed the front one on my '04 Monte with a L36 while installing a ZZP Plog. The front lift bracket has one bolt directly to the head. The other side of it is attached to the exhaust manifold STUD and held to that stud with a nut. So, a tiny exhaust stud DOES share some of the load. I had no reason to mess around in the back, but I would imagine the rear lift bracket is the same way.
 
OP.. unbolt the dog bones at the motor side. The one on the coil pack has a second bolt hole back a little. Pull the motor forward and put the bolt through the dogbone and that hole. This is there to hold the motor forward. Leave the straps and other things that might break/slip etc and hurt you to the others. Be safe.

Engine lift brackets. Maybe you guys haven't spent enough time under the hoods? The exhaust manifold goes on the head. Then the engine lift bracket covers the end stud of the exhaust manifold and it held to the head/manifold stud with a nut on the stud and a short bolt to the head. Both 13mm's. Any other questions? :th_nanana:

Nick..sorry to say it man. You're the misinformation on this one. The exhaust manifold studs are not tiny. you thinking of the Racebalt?

Nope...because I'd never rely on an exhaust stud to lift a motor...hence why I don't even use the factory hoist brackets.

I've got better spots like the right dogbone bracket and the long alternator bolt that goes back in around the chain.
 
The right being the cast iron coil pack bracket. Yeah, that's good. But the aluminum driverside (aka left) one is weak and shouldn't be relied on...it breaks easy bud. Although I've never broken one. :th_thumbsup-wink:
 
ok, then how do you explain the fact that i had to pull the bracket off to get my front manifold off. ONE bolt is bolted to the cylinder head, while the other is bolted to the manifold. fail
 


counting this one, the antiseize, the coolant elbows...... actually im 3 for 4.

not cocky, just defensive. every post i make is keenly observed by bluegtp, then exploited for grammatical, and factual errors.

and i never said that hoisting the engine up by the exhaust manifold bolts was a good idea, or even safe. if it ever comes to that i will probably hoist it up using the motor mounts and alt bracket like bluegtp suggested, but the brackets will be for added reinforcement.

oh and the vr1 topic, so 4 for 5. or is it 4 for 4?
 
The VR1 topic you fail...because you don't even use it and you don't even know the reasons I run it...even though I already did tell you.

It has higher levels of zinc in it...therefore it is better for the bearings in your motor. Also, like I had previously stated...lots of large lift cam cars run a thicker weight oil because they idle lower and it is harder on the rotating assembly. I've tried to tell you all the faults in your posts so you can learn, but obviously that isn't working.
 


So technically speaking. The lift bracket is on nut and one bolt. The stud that the nut goes on is threaded into the head
 
well hopefully the zinc will even out the damage from your cold starts.
but that depends on where you live

I use the brackets on the manifolds/heads to pull motors. There's a reason they come on the motor from the factory people... Unless you have really rusted out studs I would pull there.
