FridgeFreezer Posted September 18, 2017 Share Posted September 18, 2017 I've got a Defender with a 4.6 and a 109 with a 4.6 and both go through the MOT, what in particular are you worrying about? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted September 18, 2017 Share Posted September 18, 2017 If emissions, then it will depend on the age of the vehicle, post 1992 it will need a cat. Otherwise I don't see an issue. Quote Link to comment Share on other sites More sharing options...
mickeyw Posted September 18, 2017 Share Posted September 18, 2017 What FF & Bowie said ^^^ I had a 1986 V8 90, converted from 3.5 to 3.9. Never had a problem at MOT time despite their computer thinking it was still a 3.5. My current 1986 V8 110, was 3.5 then 3.9 and now 4.2. I've not had to MOT since the latest engine change, but been through 2 tests as a 3.9 without problem. That's 3 different MOT stations too. 1 Quote Link to comment Share on other sites More sharing options...
