I "THINK" they were Mopar Perform covers when engine was built ( 20 years ago ) But Im not 100% sure

tops of the tubes near the O ring is bone dry


At this point , Im thinking My plan at the moment is pull valve covers again when car goes down for summer break late June thru late Aug / early Sept time frame ( black car with no air in 110-115 degrees ambient temps doesn't sound like much fun )

I'll do these tube inserts and valve seals same time . But I'm taking it on a 4-1/5 hour trip the 1st weekend in June and I want to stop oil getting inside the tube if at all possible .
