  1. This is my 1.0E Lupo....  I got this little car in October with the intention of using it as a stopgap car to see me through the winter. It certainly has got under my skin! Plagued with a constant idle speed misfire and wrongly diagnosed multiple times, I decided to do things properly and investigate fully as to the cause ..... This turned out to be an expensive journey that we are about at the end of. Firstly I decided to grab a spares car, simply for its engine and a couple of other bits as it also had an AUC 1.0mpi in it that seemingly ran flawlessly. I had no issues pulling it to pieces as it ended up being extremely bent, to the point that the entire front end moved when we removed the front crash bar. It didn't in the slightest bit drive in a straight line. And I thought, the engine was fine (the main thing I wanted it for). Progress was fast in removing important parts I wanted. But anyway back to the engine situation, I had issues with some of my engine removal tools being delivered and in the mean time I did much research into issues with burned valves and worn valve guides on these AUC engines. It was decided to take the head off as a precaution before fitting the engine ..... I'm glad we did! This engine ran fine, no notable misfire, no smoke, however there was an obviously dead lifter. As the head was removed it became immediately obvious that exhaust valves on cylinders 1, 2 and 3 were badly burned. The cam was also binding and scored on the journals. So, off to the engine shop it went! Report was 3 valves burned, all 4 exhaust valve guides worn way beyond tolerance, the cam had to have the bearing faces polished and the top was twisted..... Great! The good news is that £320 and almost 3 weeks later, it was ready to collect... There is a lovely job. All inlet valves cleaned, new exhaust valve guides x4, new exhaust valves x4, reworked camshaft and best of all 3 angle valve seat cuts across the board with new valve stem seals and a complete head set. I do however wish people would service engines properly. The next job on the list was to clean and re-oil the lifters as we knew one was dead, just not which one. If you don't change your oil often enough let these next pictures be a lesson as to why you should .... that was simply what was stuck inside the lifters. Carbon, grit and other dirt. This engine hadn't had frequent oil changes and this is the net result. After everything was cleaned off it was re-oiled and stored in oil for the next couple of days work ahead so nothing goes rusty and I don't need to worry about dry lifters.... and just for prosperity here is the dead lifter ....It will stay compressed....Or extended, but will not spring as it should. There is also no sign of a spring internally when pulled apart so that's possibly in the sump. There you have it, my VW Lupo that was purchased cheaply and intended to be thrown away. Getting a second shot at life because I have somehow become extremely attached to it. I will update on progress as I go.

  2. The qualitty of some details in this car is very low, therefore I wouldn't trust the overall qualitty of mods is normal. For example I can list exhaust pipe, which is turned right, and interior which looks very bad, don't even have mats on floor.
