Bad timing!!!!!

My 1 ton has had a little vibration going on somewhere in the drivetrain for about 2 weeks now. I thought it was something to do with my clutch or preasure plate because i could feel it in the cluth pedal when i push in on it. Well today i started checking it out and noticed an oil leak developing at the balancer seal. I grabbed the balancer and could shake it up and down! The bolts where tight so i figured i would pull the balancer and find the keyway messed up and the balancer needing replace. WORSE!!!! I could move the front of the crank up and down and in and out! It has good oil press. and no knocks. I think the crank has broken toward the front but some how still spinning every thing together. Ive seen them break and tear a bunch of crap up but this will be interesting to see when i pull it apart. Bad thing is i have to drive the Velle to work and back untill i get it back together. I'm hoping to just flip it over on a stand and put a new crank in it without pulling the heads and pulling the pistons out. We will see....

Wow that's crazy. Bad timing too. X mas time and it's cold to be working on stuff.

Yea i take two weeks off at the end of every year and try to do nothing but i got too squeeze this in .....

Let me know when and we will try to get a couple of hand to help out.

Thanks man

Just as i thought....crank was broke behind #1 main...still ran with good oil preasure .....It had a vibration but no knocks.......nothing in the block is hurt so i may just drop a new crank back in and call it good....i thought about putting a 400sb in but i may do that at a later time.....all in all i was lucky it didnt scrap my block

.

Lol! Yea I did, I figured if I could drive it home at 70 mph with a broken crankshaft, then with a new one back in there It would be a keeper. I will remain a loyle Chevy guy. It will make a good conversation piece on the shelf with the years of boken rods, melted pistons,busted 4-speed bellhousings (clutch explosions),broken axles,and whatever else got tore up. But look at all the fun we had! Lol

That's wild..I've never seen one do that and stay together..

Wow. I will probably never see that again!

I got the engine out today and on the stand. Here is what the rest of it looked like...ive been wanting to put a 400 in my truck for a long time but never could make myself take it apart, but i think now that i got it apart im ready to just make the change....

to a 400 u will need it to pull that car to the track next year going to go a lot more next year

I drilled the steam holes in the heads and put the Fuel injection intake and all the sensors on my 406

Got it back in the truck and almost done....Got to wait for advance to open in the morning to get a few things...i just hope the ECM will behave with the cam i used and the extra cubic inchs....i will most likeiy have to put a hyper chip in to take full advantage of the upgrade

man you work fast.
I figured you would be sitting around relaxing today.

Lol...yea i got it running around 11:30 tonight before i went in.....i need to finish up a few things and adjust the valves and timing but i was able to back it out of the garage before i went in ......I put some oil in there from Speedway so i wouldnt have to wait to tomorrow to get it started.....i will change it after it runs a bit......

you the man dam you are fast
