Model: Seat Arosa 1.0s
Engine: 1.0l 8v in-line 4 Multi-point Injection

Hi guys, I recently bought a Seat Arosa 1.0s (very similar to the VW Lupo). I have owned the car since March 2013 and thought it was about time to get a build thread up to track the little things i have been doing. I bought the car for £650 with a misfire, we thought that this may be a simple fix such as new coilpack etc. The car was on 79,000 miles which is relatively low mileage. However, after replacing the coilpack, spark plugs, ht leads, lambda sensor, injectors, injector seals still no luck. So as a last resort we decided to strip it right down to find what the problem was, we stripped it down to find that the first piston had pretty much seized and had been smashing against the head. It looks as though the previous owner had never heard of oil :S ........

That's a bit of a pain in the arse. Sadly, oil use can be a bit of a feature on the aluminium VAG engines, although the 1.0 was by far the more reliable one in the lupo/arosa. The aluminium engines don't generally rebuild well, so you're probably better off trying to find a good second hand one.
