How to remove engine?
I have a loud knock in my engine
We checked all the valve's they are good.
We checked the injectors they are also good.
So we think it is somethink like the piston's or bearings.
We want to take the engine out of the truck.
I've ones heard someone say that you need to remove the whole front including bumpers. Is that true??

Yes, that is very true. Why not remove cylinder head first? If piston is bad you will be able to see damaged piston. It will make removing engine a little easier too, less weight and more clearance to remove engine block. Still need a heavy duty engine hoist. Very big job, I would be sure you need to remove engine to make repairs first.

Thanks a lot.
My neighbour is an mechanic, he is doing the job.
The plan was to use a very small camera(like they have is hospitals) And put that camara in the injector hole's to look at the inside of the cilinder head and pistons.
But the first camera was 2mm to large.
The second camera is in Germany
And the third camera isn't working.
So my truck is now standing still for 3 weeks.
How much does the engine weight? I have heard more then 800KG is that true?
And how much does the cilinder head weight?
I will print everythink and give it to my neighbour.

I just pulled my head off. I used an engine hoist. It would be VERY difficult for two people to lift it off.
I believe the engine can come out without dropping the tranny but the oil pan would have to come off first. I got mine off fairly easily by removing the valve cover and loosening the motor mounts then lifting the engine till it just touched the cowl. After that the oil pan slid out the back easily. Once its off the pickup can be removed. Now there is nothing to get caught up on the cross member and the engine can come straight out.

Well I sure hope you get a hand putting it back on cause I cann't see how one guy would do it without a crane and not damage it..... or himself. If you work in a shop you owe it to yourself to work smarter not harder. If you plan to be in this trade for life then you need to start thinking about your career down the road. One day you'll be doing something simple and you're back will let go. Its all accumulative.
I picked my hoist up for $150 at one of those discount tool sales. Cheap but it works. Just used it last night to put the head back on my '01. I've taken dozens of engines out with it and lent it out many times as well. Pretty cheap tool in the long run.

It won't go back on for another week or so, and it'll be quite a bit lighter by then (porting & no plenum
), but I'll still let someone take the "heavy end" if they're around.
It is my shop and I have been in this trade for life - at least I don't pick up big blocks or Rabbits anymore! 
Must be wising up in my old age.

I pulled the head off a CR in the shop last week by myself (no one else was around to help)... one day I prob'ly need to start using a hoist!
