Did you get it running yet? We're all waiting to hear it. Don't forget the speedo vids as well

 

I just got back from the shop. The beast lives! I am also very pleased since I did all the work myself and have never done something this in depth before in terms of engine work. I need to put my air intake back on and clean my engine bay tommorow, but other than that its done. It runs strong but I only had it runnign for a little bit before I had to turn it off b/c there was an oil leak. Not a big deal, I just didn't fully snap in one of the quick connect lines to the radiator all the way. I shut it off, put cat litter on the oil and snapped the line in all the way. Took about 5 seconds to fix, and pretty small issue for a first timer doing it all by himself, so I'm pleased. By that time it was already dark, but I just wanted to hear it run. I will be at the shop early tommorow to clean up and do the break in on the cam/springs. I have to finish my truck, and then button up a couple things on a project 6 months in the making. Its a 1990 YJ that I built up from a rolling chassis. 350, 700R4, NP241, Slip-yoke eliminator, SOA (spring over axle conversion), Ford 8.8 swap w/ e-locker, 4.88 gears and 35 X 15.5 in. Super swampers. Then I have to load up the Jeep on the trailer behind my now cammed 6.0L and get ready to head back up to school for class on moday. I have basically been working all break on car **** and I'm really glad to finally have it all done. I will try to get video asap of the new cam. Hey btw way how do I resize those pics so they will show up. I think they are too big.

Here is a picture of the Jeep:


Here is a pic of the truck:

 

Congrats! To do pics just upload them on photobucket and then link to the images on this site

 

I fixed the pics for ya chevy6.0fan, you made the mistake of doubling the HTTP: . When you hit the "image button" you have to make sure you paste the code over the one already in the dialog box. I made the same mistake/learned this earlier

 

Update, the truck is no longer running and I'm stumped on the problem. I was holding the truck at RPM's trying to get it to idle with the new cam when it just died. Checked all the obvious things; spark, fuel, crank position sensor, I even switched the computer, but had no luck. Ran a compression test and I wasnt making any compression on either side of the engine. Took off the valve covers and none of the valves were opening and closing. Now im really worried so I take everything back off the front to find a broken timing chain. I pryed a little on the cam gear to see if I could get it to move with no luck. So I took off all the rocker arms and removed all the pushrods, none of which appear to have any damage. I took off the cam gear and was able to turn the cam smoothly except for one area where it was binding a little, but it could still turn a full circle.

Could one of the lifters have failed? I know I degreed the cam correctly and it spun smoothly inside the block when I put it in on the initial install. Also, before the engine died it seemed to be runnign smooth and strong. I'm stumped, frustrated and mad. Initially I thought it was just timing chain failure, but now it seems that was probably caused by the binding load on the cam turning in the block. I never even got the truck over about 2000 RPM's with the new cam.

Any ideas would be greatly apprecitated. I was very careful to follow procedure during this entire install, and the truck was running fine before, when all of a sudden this just happened.

 

A few things, did you buy the cam used? Is this the first time you used this cam in your motor? When you had the heads off, did you do anything with the lifters or lifter trays? Did you take the lifters out and inspect them at that time? Could a lifter have turned on you? Now when you say you can feel binding in the camshaft when rotating it, do you mean you can still rotate the cam 360 degrees or does it stop in a particular area of rotation? Since you have it torn down as far as you do, I would pull the cam gear and cam retainer plate and see if you can insert your lifter dowels into the holes. If your dowel rod is not going through for full insertion, I wonder if a lifter managed to rotate? Did you take out your lifter trays at all or did you overtighten any of the trays where they may have cracked causing the lifter to rotate? Just throwing ideas out there.

 

Update. I came back into town from college this past weekend to take care of some things and I was able to work on the truck on sunday and monday. The broken timing chain was unfortunately not a lifter problem. A cam bearing spun inside the engine and i can't even get the cam out of the block. Now I'm out 1800 bucks for a used LQ9 out of an escalade. I'm really not sure why **** like this always happens to me. I am very mad right now and can't really figure out why this happened. I was very gentle taking the old cam out and the same putting the new one back in. The new cam was well lubricated before it went in, and spun nice and smooth when I put it in the block. All the lifters were fine.

I was just trying to swap in a small cam for a little more power, not destroy my engine. I don't know who to be mad at. Sure, if I had never pulled the cam in the first place then the truck probably wouldn't of had this problem, but I was so careful during the whole thing as this is my daily driver.

BTW, the spun cam bearing also destroyed my brand new camshaft. I'm so ******* pissed right now I dont even know what to do with myself. I will update all of you when the new (used) engine is in.
