But you are -To quote
We didn’t put this motor in & feel we should not have to bare the cost of certification.
We have all receipts from mechanic who put in motor & all inspection forms.
Who should be responsible for this mess we find ourselves in ?
I don’t accept “bad luck” as an excuse for others not doing their job properly.

Stating facts is all.
Your idea of taking responsibility & mine differ.
I have accepted that I have to remedy this.
I don’t accept that it should be put down to “bad luck”.
Why have laws if they are too hard to enforce so that they are only enforced sometimes?
Are you or have you been a COF inspector?
That would explain the “blame” you are excusing them from & lumping me with.

If it's on a COF, it may well be a heavy, which falls under Heavy Vehicle certifiers, not LVV.

Go somewhere else for your COF.

traykuku, Jun 9, 3:23am
It is now recorded against the vehicle & no one can pass it without a certification.

Exactly.

I know of trucks that have had a engine rebuild and in the process they've been taken from 350 hp to 400 and even 1 or 2 to 450hp, most are just a cam, turbo and injector change, maybe pump as well.
No way anyone would know they've been uprated unless clued right up on Cummins.

Which means the same thing in this context. An external approval still has to be sought.

kaz is correct, blame whoever you like, you will still need a cert.
I'm in the same boat with a turboed motor install into my coaster bus.
Was going to try and blag it at the next COF, but realistically I'll end up at the heavy vechice cert

traykuku, Jun 9, 7:38am
Pretty sure I’ve said I have accepted that more than once.

traykuku, Jun 9, 7:41am
Thanks for advice received here.
Hopefully my wee rant will save some other person similar bad luck.
Will plug on with getting the camper legal & sold.

Yea yea I know, cc has increased> thats an interesting trick because a max rebore (or overbore) also ups the cc rating but isn't classified as such for cert

franc123, Jun 9, 10:44am
Thats right. But of course you could only determine that with the head off. A scenario I thought if was say you had a 3.9MPFI EA Falcon with a buggered engine, you can fit a 4.0 ED engine in no problem which technically requires a cert, yet you can recon/ overbore your 3.9 by 1mm which will take the cc rating a good 70cc past the capacity of a standard 4.0. Yet thats perfectly ok.

The engine number could be obscured by a thick layer of grease.

mrfxit, Jun 10, 12:30am
Not that the 3.9 is worth doing anything to apart from scrap.
Driven a couple / heard a lot of storys, not great, don't thing an overbore would really do anything anyway

franc123, Jul 28, 6:55pm
Lol it was a theoretical excercise explaining the silliness of certification laws, not something you would necessarily do.
