Motorway Service Stations Calendar - September

Stayed at a Travelodge in Kendal and then on the 1st of September went up to Annadale water services to tick off September - a trot of only 84 miles. Then tackled the 280 ish miles home which was much nicer with short stops off at Markham moor & leeming bar services. 641 miles covered in total in 2 days according to google maps, and apart from a couple of non starts (attached jump pack and she fires up so will get an new starter motor) #thegreencavvy was faultless and averaged 39.7 mpg on

Club Updates

Right then...

After 3.5+ years living over 5000 miles away, we’re finally coming home to the UK. And that means becoming active with MK2CAV.COM properly again.   Somehow, our weird little website started back in 1998 is STILL alive. Which honestly feels slightly miraculous considering the modern internet now mainly consists of doomscrolling, AI slop cat ninjas, ragebait and “what wheels fit?” posted 140 times a day by people who apparently fear the search function more than terminal rust. Comparativ

Motorway Service Stations Calendar - April

This time it was a close one.   #thegreencavvy never made it to Rustival as a week before the temperature gauge went into the red after a little local run about.   We changed the thermostat (3 times), flushed the engine, changed the water pump, replaced 2 hoses, took out the radiator and flushed it but each time straight into the red after 1 mile of driving.   Went to wire in a fan bypass switch and noticed the alternator was kicking out over 18volts!

Motorway Service Stations Calendar - Feb

2 of 12 complete Stop number 2 of the Motorway Services calendar completed yesterday in the #greencavvy - 336 miles and she didn't miss a beat. This time for the journey i took my good friend Martin Drummie as well as my son and we met up with the lads at The Crap Car Collective (https://www.facebook.com/groups/1246037256564774) for tea and biscuits and an update on the Marina. Reading next month but i think #greencavvy has earned a rest and an oil change. #vauxhall #vauxhall

Motorway Service Stations Calender - Jan

I got my son a motorway service station calendar for xmas as a stocking filler and January is Ferrybridge Services on the m62 - a mere 229 miles round trip.   Armed with the latest ebay purchase of 'now thats what i call music' (correct age for the car) we started out at 10am and the #greencavvy #a32ltm  was absolutely magnificent as always despite the filthy weather. Got back at 15:40 and averaged about 33.5 mpg   Leeds Skelton to do in febuaray

Bosch Motronic 20XE / C20XE 4.1 / 2.5 / Overview

Put this together for my 20XE from a service manual. Found the entry for the 2.5 on the Corsa forum. Hope it's of some use! Mods/Admins: Feel free to make additions / extensions / corrections. NB: The 4.1 version is first, followed by the later 2.5 catalysed version that also has a dizzy.  Not for coilpack / dispak  setups per se (sorry Greg!), but these were similar to the 2.5 version which follows the 4.1 version.  NB: Early 20XE's - These first valvers may have different loom c

Hello there this is my first blog or even writing anything like this so I hope that it turns out OK and more importantly is easy to understand for someone that is this as a guide.  A special thanks goes to neilsri130 as this was originally his idea I just put together this blog of my representation of his idea.

Brett's Great European Adventure - Part 1

7 weeks, 8 countries, 4763 miles, 1 Overly optimistic owner and 1 slightly unreliable 80's repmobile. This is the story of my adventure around Western Europe in a 1987 Mk2 Cavalier SRi OK, so firstly, yes this has taken me ages to get round to writing up!  A bit of background to why I managed to wangle such a long and eventful trip - I decided to quit work and spend all of 2015 travelling as much of the world as I could. Starting in May, I ended up in Thailand for 2 months, the USA for

Brett's Great European Adventure - Part 3

Here we are then, part 3 and the conclusion of my trip around Europe in my Cavalier SRi.  Picking up in Italy, I left Milan and Monza behind me having not broken any laws by breaking onto the track in the car..... just! Itallian organisation is something to behold. Or, sit in your old car in 35c heat in a traffic jam because they see fit to have 2 toll booths out of twenty open, all so they can rip you off for the privilege of driving on their dodgy Autostrada. Have I mentioned Italian moto

Brett's Great European Adventure - Part 2

Welcome back if you are still reading my ramblings of last years trip...   I will pick up from the campsite in Vence having just dodged the Tour de France, in the Alps above Nice. A couple of my mates were flying down from Holland to meet me for a weeks relaxation in Cannes and I was picking them up at Nice airport.  I'd put about a fair few miles on the car problem free by now and all was going well you could say guess. I was pleased and feeling confident, when suddenly the arse

Fitting longer front subframe arms to a 1.3 or 1.6 shell

This has come up a few times now and as decent shells 1.8 & 2.0 become more scarce using lower spec cars as a project base makes more sense.   The main difference between the 1.3-1.6 shell and the 1.8-2.0 shell is that the 1.8-2.0 has a more beefy front subframe and crossmember setup. The issue is that you cannot simply transfer the subframe across. The longer subframe is located by 2 bolts in the centre while

F18 5th Gear into an F20

The idea of this mod is to give you better motorway cruising by fitting a WR 5th gear while keeping the decent acceleration of a CR 1st - 4th.   You could just go all fancy like Andy and fit an F28 but this is cheaper and gives you lower revs in 5th than the F28 in 6th.   I'm fitting a WR gear to my F20 but its the same procedure if you want to fit an F16WR 5th into your F16CR or if your fitting an F20 gear cluster into your F16 housing this is a worthwhile mod.   F16s all share the same select

Rear Disc Conversion

This is a basic how-to on converting to rear disc brakes using mk3 cav or astra hubs. This is a very simple swap and is very worthwhile since the disc setup brings both better braking and easier maintenance.   Now if your thinking of doing this I assume you can remove the beam yourself so im not going through that. The rear brakes will need to be bled afterward and there is a small bit of welding needed on the handbrake adjuster.   The easiest way to do it it to get your hands on a complete mk3

F20 Internals in an F16 Housing

This is a basic how-to on removing the internals from an F16/F20 so you can swap the housings over to allow you to keep your F16 housing.   1   Remove the gear selector turret by removing the four 11mm bolts at the base and giving it a tug and a wiggle.     Disconnecting the gear linkage can make this easier, if you do this make sure you split as in the pic below not by undoing the bolt on the shaft to save you having to reset the selector.     2  Next remove the reverse light switch.
