I keep reading stories about VOSA & DVLA tightening up on the proof of engine age .... I believe that some centrers are now insisting on documetary evidence from the engines manufacturer !!??

Guess the problem with a V5, the engine may have been changed for a later unit ( Not absolute proof of the engines date of manufacture )

Must stress though, it is ony information taken from the net & as such, I do not know for a fact

If it's a ford, then the engine number is part of the VIN. so you can prove the original engine is used.

This is how i proved age at iva with no probs, but as always no two test centres are the same so i wouldnt bank on it

V5 doc alone will no longer normally be accepted as proof of engine age. This is because of the large number of people during the SVA years who tried to get round emissions test by registering the donor with a different engine then building their kit.
With SVA, emissions was based on age of donor vehicle and assumed the engine was the original type for that vehicle. Too many people got caught building kits where it was blatantly not the original type of engine from the donor.
As TT says, where you can prove the donor engine is the original from the donor car then V5 doc may be accepted.
It should not, however, be a problem to get written conformation from the manufacturer of the engine as to it's age and this will be accepted as proof.

The engine age for Fords is easy to prove, I used the engine age page from the Burton catalogue, copied the page for the document folder and took a full catalogue with me, the VOSA inspectors have seen this many times before and are both aware of the age chart as printed and accept it.

if any one is having to use a cat things to take into account are not all cats are of the same constrution and size. some cars have them fitted right at the manifold and some ferther down streem (cats need to be hot to work but not to hot to burn up)
also bikes are not cat tested in the uk so not sure if thay would be a test pass

i would try to take into account engine size/bhp, distence from cyl head for a start.
