R400 K when to refresh

[Brett Nield]

Hi all
Just wondering wether to do a refresh this winter, 10 k miles but previous owner didn't do a lot of track days mostly touring I believe. I ve done the last two years on track only, probably about 1500 miles.
The thing is the car runs as sweet as the brand new one I had previously, really cool , minimal oil usage though it is changed regularly, absolutely no signs of gasket failure.
The story is the car was originally owned by the chap from Arch Engineering so it is probable that it was used vigorously in its early days.
Are there any tests to carry out to determine if I'm about to upset what appears to be a good unit
Cheers

If it's not broken why fix it? .

I was thinking along those lines Mick

Common sense prevails !!!

You could fairly quickly and easily get a compression test done but as said if it's not broke, then don't fix it!

Give it a compression test and check the valve clearances, if both those check out OK then heave a sigh of relief and keep treating it to regular oil changes.

If nothing else, get the dry sump pump refreshed. Titan will overhaul it for around £100 and you'll regret it big time if it fails or can't keep up with oil demand ....

Also, check/clean the small gauze filter at the end of the scavenge pipe which feeds from the sump. This can get blocked with small debris and reduce the flow.
