K-series inlet O rings - RichyF
The car-by-car-breakdown section mentions the following problem with the K series engine

'inlet manifold 'O' rings tend to perish between 25 - 30,000 miles'.

I have seen this comment on the Parkers web site also.

Can anyone confirm where these 'O' rings live... I was under the impression that a gasket sits between the manifold and head gasket and I cant figure out which 'O' rings are being refered to...

Any ideas?

but I'm sure you all spotted my deliberate mistake

This isn't really a reply as much as more questions...

What are the symptoms of these o-rings having perished? My car is really lumpy when on choke and holds its revs between gearchanges, are these symptoms of perished inlet o-rings??

Richy-F, if you have found out any info could you please let me know...

Thanks,
