[Fot] Oil Cooler or Oil filter first?

[robert bownes]

After cleaning out a filter that survived a bad bearing in my 1147 Spit
(Back in the Day) and re-using it (It was after the filter), the next
engine lasted a whole 22 minutes, about 3 sessions short of a race weekend,
before the very same failure occurred. I've never re-used a cooler since.

But I do have a stack of 3 or 4 for anyone who wants one. :)

I miss that car. But not the grenades that it kept under the hood.
