My Fault Timing Belt Change

[Jacko1987]

Ok so Iv changed my timing belt test started with out the balancer on ran fine I only wanted a few seconds then turn off complete the job but the turbo timer kept it running before I could kill the turbo timer the belt slipped off stopping it for me .. While I'm currently uppercutting myself run me through some scenarios of what damage I may have caused

Cheers in advance no bashing [emoji106]

Hurting deeply

ouch.

there is only really one thing that can happen, bent valves resulting in no compression on 1 or more cylinders. And it almost certainly will have done that.

[Jacko1987]

Cheers Duncan .. Iv got people that can do it any idea where to get valves from

Only thing I can say is..........glad its not me!!!

Why did you test it with the balancer off?

If the timing marks all line up there shouldn't be an issue, and if you are really worried then turn it over by hand, that way you avoid this kind of disaster

Tips for next time

[Duncan]

yeah mate Nissan will have valves readily available, but it's not that simple to fix, at a minimum it is head off to do so.

I've tested an engine without the balancer before after I had an oil pump seal leak that I wanted to make sure was OK. But I did run the balancer bolt and a big washer to keep the timing belt on.

everyone has a brain fart now and then, and I'm not in a sharing mood

Get a leak down tester (but fit your balancer on first) and do a leak down test so you can hear if and where the valves are bent before pulling stuff apart.

It may be than only a few valves are bent, you can sort of get a indication of how bad it is before you pull the head off.

This is why I leave it to the experts,sorry for your probs . :-)

Another tip - get rid of your turbo timer - more trouble than they are worth.

[Jacko1987]

Yes so I found

[Jacko1987]

Been awhile but not forgotten so Iv finally got the head off(alone) found that 1 and 5 outlet valves don't sit properly what you fellas reckon be able to just whack new valves in or need new seats aswell ...

[Jacko1987]

In most cases just replace the valves with good ones and get them lapped in.

1 & 5 cylinder big end bearing has obviously copped a little wack also.

Not a nice feeling I've been there
