My view of the HG problem is because it was designed as a 1.1, and has been bored out further for others. The 1.8 was the most prone. Is this right, or is it another design issue?
From experience the 1.8`s VVC`s (143bhp) are VERY prone to goint and hard to fix.
However the twin cam 1.8 (120ish) doesnt have a record of this.
1.6`s are okay and usually 1.4`s are the most frequent to go.
Think the original K was from a 1.4 or 1.6 engine as certainly in the rover 200 series/ 25 series the 1.1`s came a bit later into production :-/
I though the 1.1 was the first out, and fitted to Metros, followed by 1.4?
Is 1.4 more common failure simply because there are far more 1.4s?
Mine is a 1.6, and failed. Always had regular coolant changes (told old coolant may be a cause), though last change in the summer, I flushed and put in Vx Red - was this a mistake?
