Dan Lesser is a Viper GOD!

GTS Dean · October 17th, 2016, 08:24 PM

Through 3 months of major suspension/brake and minor engine work, new exhaust system, a full underbody detail, suspension and bodywork alignment - my car was ready to fire up and take for a spin around the block for a systems check.

After a week of trying to diagnose a no-start condition, I popped smoke and called in tactical support. I described my situation in detail, along with the symptoms and DRB readings. I tried multiple things and we emailed several times over the weekend. Dan then suggested something that was so far-fetched and outlandish that I kept dismissing the unthinkable until it was about the only thing I HADN'T tried...

I pulled a valve cover and checked for valve operation. There was none.

I am demoralized and my spirit is crushed. I have to take the fucker back apart again.

That is all.

You forgot to put the cam in?

dave6666 · October 17th, 2016, 08:35 PM

Or timing chain?

GTS Dean · October 17th, 2016, 08:43 PM

I never took the cam out, and only checked the chain for stretch. I don't know if the cam bolt broke, or the camshaft broke. All I can think of is it may be related to trying to get 250 lb-ft on the crank bolt after re-sealing the timing cover. I had the SOB idling in the driveway while flushing the cooling system and the damn thing just quit running. It never would re-fire.

Hell - I'm the only person I know that ever had an automotive camshaft quit working as a root failure cause.

Let me know if you need a new cam sensor

GTS Dean · October 17th, 2016, 09:18 PM

Your offer is very kind. Hopefully, I won't need it because it still shows a synch signal after about 1 rev and the plugs are firing.

71firebird400 · October 17th, 2016, 09:52 PM

Wow, what a fluke. Let us know what happened when you get it apart!

Ramtuff · October 17th, 2016, 09:54 PM

Probably sheared bolts and pin, Hopefully the cam is not too messed up, good luck!

I had a SBF years ago with a new Comp cam that broke the pin,was idling ok then put a few rpms to it and it just died. Took about 20min to figure it out (poped open the distributor cap and the rotor wasn't spinning) cause there's a distinct difference in engine sound when it turns over but it only bent a few valves.

Bump for Dan Lesser. He's been around a long time. I've never had to call on him but I'm sure the day will come.

**Whitebeard** · October 18th, 2016, 10:08 AM

I've talked to him several times, helping him on different topics. He is more than patient and helpful, even to a noob.

He and his staff are quite friendly. I can't say enough about them.

dave6666 · October 18th, 2016, 10:13 AM

I like him. I mean, why wouldn't I. He's been tuning on my car for 17 years. We'll have it perfect in just 5 more years. Maybe 8

This is one of those situations where I was hoping I was wrong. I actually alluded to this being the problem in the first e-mail when I was saying "I had an idea, but didn't want to say anything without more info" as this was basically a worst case scenario.

In any event, I hope you keep us updated on what you find. This is not the first time I have seen this... this would be the third time.

Wayne64ss · October 18th, 2016, 03:14 PM

Dude wtf!!!! That sucks.

Were the other occurrences identical failure modes? Sheared timing gear bolts? Broken cam?

I totally had the same issue once. The little pin that comes out of the cam into the cam gear broke off. to the gear spun but the cam didnt. I went to a cam that requires 3 bolts now! LOL

Same situation as you...pulled car out to wash it. couldnt restart it. I was like how the F??!

plumcrazy · October 18th, 2016, 06:58 PM

One case was loose timing gear bolt and sheared dowel pin, the other was a seized camshaft that resulted in the same.
