Divot worn in Valve Stem Options

[frank_c]

Hello,
I started replacing the Pushrod Tubes yesterday, and I noticed that the top of the stem of #4 intake valve has a divot worn in it from the rocker (#4 valve stem & rocker adj screw photos below). The other three valves on this bank are fine, and I haven't pulled the rockers on the other bank yet.

I purchased the car about a year ago, and here is some engine related info based on an engine build sheet, the receipts that came with the car, and what I can see:

• 2.0 with euro P&C
• Weber 40 IDFs
• WebCam #86
• Standard Aluminum pushrods
• Standard 2.0 rockers

I do not see valve springs listed on the build sheet, so I am assuming that the single spring currently installed is the OEM spring, and not an HD spring.

So, I have two goals here:

1. First is a short-term fix as I plan to take this car to the Hill Country Rallye in Mid-March - so no big tasks that might go off-script. Car will be driven 600-700 miles during this event.
2. Second is post-rallye where I plan to move to 1.7 rockers with swivel-feet, chromoly PRs, set valve geometry, and whatever else folks might suggest while I'm in there (solid rocker spacers?). And can this valve be saved? Am I looking at pulling the head to either repair or replace the valve?

For the short-term goal, if I leave things as-is this will obviously make setting the valve lash on that valve challenging. So I would like to hear folks' opinions on the use of a Valve Cap on that one valve (and any others with similar issue I may find). If I install a cap, should I replace the rocker adjustment screw for that valve as well? Or is there any other short-term option that does not involve pulling the head? Or just run it as-is knowing that #4 intake may not be getting full lift, and tear into it after the event?

I also have some questions regarding the long-term fix, but I'll leave that for another thread when that time comes.





Thanks,
Frank
