A few questions...

I have a Robin Hood S7 which I've been restoring for the last 2 years... it's on an old Pinto engine. Will it be just the 'visible smoke test', and how much smoke does it take to fail ?

When it fires there's a faint blue haze and a slight smell of oil, but once it's warmed up it's fine... do I just present it with a hot engine ;) ?

As it hasn't been run on the road for 7 years (and hence I don't have the old MoT certificate, is there anything special I need to do ?

Sure I'll have more questions as time goes on

Cheers

I believe you have a choice as to when to present it, and I certainly forgot to present my 944 after it had been lying around for a couple of days.
Instead it came to the station nicely warm, and with no smoke at all. Imagine that

According to my MOT man , smoke is not a problem. Firstly it has "no" ( negligible ?) affect on the emissions , and secondly , he saaid that he would only fail a car if it literally obscured the road.

My old escort just scraped through

Cheers guys, that's put my mind at rest...

The blue tinge is just about visible on startup, and it could even be down to lack of use... I'm planning on taking the car to elvington airfield when the Ne7ers have their next trackday and giving it a shakedown blast along the straights, retorque of the nuts etc just to check it's roadworthy

I wonder if a blast from York to Stockton counts as "Driving to a pre-booked MoT" ?

the smoke on start up on a pinto is usually caused by the hardening of the valve stem seals.

All MOT stations should only check a car when it is warm and they are usualy inside the car busy starting it when its all happening.
Some testers just rev the car lightly to check for excessive smoke (i did)

Its not a bad job to replace the stem seals and a decoke and new timing belt would not go amiss if its been laid up for a while.
A day should get it all done.
