Random Oil Leak during Practice Rally

[TargaWoods]

Howdy all,

During a run last night, I noticed a larger than normal oil leak under the right heat exchanger. Upon investigation it seemed to be starting somewhere around the top right passenger valve cover area. The oil pooled mostly on the engine tin and then dripped down.

No leak from oil filter. No obvious leak from valve cover itself, Seam mostly seemed dry.
I tightened the Cam oil lines down months ago during the engine rebuild And I used RSR seals on my rocker shafts.

I’m going to double check everything, clean up the oil and watch for the origin. Posting here for any extra ideas for what it may be.

Yep, good chance your culprit is with the chain tensioner oil lines. I had a similar issue and simply tightening them wasn't enough. Had to replace that top middle line (which was a surprising PITA due to having to bend the new line to fit).
