Recovered home

[Bobreoc]

Not a great Sunday.

Had a lovely day up elan valley until I broke down on the way home, it’s doka with a 1z conversion. The van was running really well then all of a sudden the wheels felt like they locked then into freewheel then the van cut out, I managed to get it into a lay-by.
The recovery truck turned up pretty quick all I could see was that the lower crank pulley on the alternator belt had come away, not completely but all the nuts look like there in place.
It’s dark now so I can’t investigate any further but what are people’s thoughts? Could it be terminal. There was oil leaking from the sump as which hasent happened before.

Have you had a Cambelt recently?

Have you had a Cambelt recently?

No, although it’s due a change due to age

Looks like the crank pulleys come lose to me

Yea it has come loose. I just don’t know
If it’s terminal

I think what I’m worried about is, if the 4 bolts have just come loose form the crank pulley and the underneath the cambelt looked ok. Would I be ok to tighten the bolts back down refit the belt and start it? Or could the timing be out?

Given that you said the wheels locked up, I suspect the central ( 12 point )bolt which holds the toothed timing pulley to the crankshaft nose has come loose , likely damaging the nose of the crankshaft and the toothed pulley as well as valve / piston damage through lost valve timing.

As a precaution before starting ,I have found that the engine can normally be turned (slowly)by hand (against the compression)with a socket and ratchet handle on the 12 point bolt,which I would do at least two revolutions after fitting a timing belt, for example.

You will have the same damage top end as happens with a snapped cam belt, the crank will also be damaged, replacement used engine will be your best option

[Bobreoc]

Thanks for the advice.

After what I’ve read yesterday and the state it’s in, I’ll start looking for another
Engine. I’ll still have a check on the damage as it could be a spare if it’s not
To bad

WOW that’s impressively goosed

I still think you will need a new engine

[Cecil]

You have not had much luck there.

[Cobra88]

has that snapped due to using an airgun or has it hydraulic'd to start that fracture ?
