Need an opinion on my VG30

[iwayman]

Back in January I blew the vg30 in my dime.  Being back for summer I have finally gotten a chance to began working on it.  

 

So far it looks like one of my cam sprockets failed, which I think may have popped the timing belt over a few notches.

With these pictures, what options do I have?

 

You can see one cylinder had something small bounce around in the combustion chamber, however, the three pistons on the side with the failed sprocket have slight mark in them.

I'm experienced in VG's but it's doesn't look at that bad, maybe find some new heads or get them rebuilt?

Pistons are fine. Valves probably are not bent on that side but check.

Replace the one cam and the sprocket OR the complete head.

... enjoy.

You need a cam.

That dowel wasn't supposed to fall out. 

 

 

Have the head checked that caused the mark on the piston. 

Your timing jumped when that cam lost the dowel, causing the piston to slap the valves. 

 

 

Damage looks very minimal.

i agree just change that cam and pull out the other cam to see if any valves are bent. while your there change the valve oil seals..

 

 

 

vg powa!

I ended up pulling a head out of a junkyard, inspected it and everything was clean and functional so I went ahead and installed it.

 

Everything was peachy, turning the engine over without plugs in to get the oil pressure up and everything looked and sounded great.

However, I installed the plugs and turned it over again and the distributor was not spinning, turns out neither cam was turning anymore.

 

Pulled the front fascia, radiator, and what not so I could pull the timing covers and I found the belt had been completed stripped at the crank.

 

Any ideas about where I screwed up?

If you can't find what went wrong you may need to put your tools away.

 

 

My guess: You reused the belt that was on it when your cam jumped the shark.

Not very helpful.  Brand new belt.

was prolly a cheap belt or if you used an impact gun to rotate motor coulda stripped it that way....or something is still hitting. i personally have never seen this before.

 

 

take it apart line up timing marks individually try again
