I have a Ford Escort Mark 2 1981 model 1.3 L, it has been fitted with a 1600 cc crossflow Kent OHV engine from a 1.6 Escort. The original 1.3 engine makes 51Kw and the 1600 engine makes 59 kw according to Carinfo.com UK as this engine type was available as an option by Ford with no other structual modifications to the vehicle, does this vehicle require a compliance check by a low volume vehicle certifier to obtain a WOF??

This vehicle needs to be LVV certified - LVVTA association.

Hello Donavan, I am an A grade mechanic who used to be AVI certified and many years working for Ford in Auckland and Christchurch, I have read all the LVV information I can find and the only difference in the two engines is the short block is 5/8 inch higher on the 1600, with a less than 20% increase in power over the 1300 engine, I can't see your reasoning as it was an option if the person wanted it. The only other difference was a 3.54 :1 diff ratio and the 1600 had 9 inch brake drums on the rear as opposed to 8 inch drums. Can you please advise on your reasoning. Thanks Andrew

Hi, according the the VIRM, which you will be familiar with, this vehicle needs to be LVV certified as the engine capacity is larger than the OE engine. For minor modifications (such as new headers, etc) you will normally look at the 20% rule.

Please see the following link to the VIRM -VIRM Engine and Transmission

Thanks Donavan, I see your point now as it clearly states the cc can,t be larger than the original engine the car was fitted with.
Cheers Andrew
