Title: What makes an 8 valve vitty throw a rod????
Post by: Disco-Ron on May 07, 2007, 23:39:06

A mate has a slight issue with lumps of his block not being where they once were, and a conrod being vissible,........

Is this common...?? (45k fsh) or was he very unlucky?
If common..... what makes em go? cos we're gonna drop another motor in it shortly??

Thanks.

Have heard of them eating valves but this is the first con-rod I have heard of going the way of the dodo. What was he up to when it went?

Normally a result of the piston seizing in the bore, never heard of a Vit doing it though.

Just spent a few hours attempting to get the old unit out, not easy are they..... all the gubbins behind and under the carb is a right pain.....

He was just cruising along, not fast, not silly revs or anything..... sounds like (hopefully) he was just extremely unlucky...... no2 rod broke!

Thanks guys!

Worst I've seen is No1 and no4 exhaust valves being non existant and melted piston in no4.

I guess its possible the piston could end up welded/deformed enough to seize. Would love to see pics of the post mortem.

Youd have a lot of warning if that was going on though.

The only slight hint he had that something 'might' be amiss, was when he started it from cold 5 miles before it went pop, there was a small amount of what he described as 'steam' coming for the exhaust for longer than just condensation that you normally get....... but thats all that he detected......

I wonder if it had water in the cylinder and it hydrauliced, that would do it.

IT would, but it would a seriously big failure to pop a rod when he was driving it, i know it doesn't take much water to hydraulic an engine, but..... anyways, all we do know is it's broke, and is being replaced!
