Those holes in the lower plenum are just casting marks . All lower plenums have them , including all 3 of mine . The lower plenum is nothing to worry about . I would not try and sand or polish the camshaft . If it were me , id install the seal and hope it doesn ' t leak . You don ' t want to make it worse or throw off the balance of the shaft . When I did this on my old engine , I used a fleathead screw driver and various picks to remove all of the old seals . Make sure you replace those idler studs D <| sep |> It let you do in store pickup with a 128 ? We have it had any in our store at all so , idk <| sep |> HE IS BACKSTRONGER THAN EVERGreat comeback , mate <| sep |> What I ' m getting at is that dismissing his point re the team Crosby played on just because Edmonton ' s team last season was bad is ignoring a lot of context , and that it ' s actually pretty relevant to the conversation if you want to portray Crosby in a better light . The parent post suggested that the 200506 Penguins were worse than the 201617 Oilers . I don ' t think there ' s going to be much disagreement here , so we ' ll just move on . Your response was that the point didn ' t matter much , since McDavid ' s first 45 games were on the 201516 Oilers , implying that team was also terrible . And it was ignoring McDavid himself , Klefbom and RNH also missed large portions of the season , the defense was it ' s normal tirefire , etc . as you mentioned , they finished 29 th for a reason . But even as an incredibly bad team , they weren ' t as bad relative to the rest of the league as the 200506 Penguins ignoring the Blues . In 201516 , Toronto had 69 points as the last place team I believe that ' s the highest number of points a last place team has ever had . As already mentioned , 200506 had St . Louis with 57 points for last place . Edmonton ' s 31 wins was second last tied with Vancouver and above Toronto ' s 29 , but would ' ve put them above five teams in 200506 . Edmonton was 17 points away from Minnesota ' s 2 nd wildcard spot last season , while Pittsburgh was 32 points out of Tampa ' s 8 th seed . People talk about how the league is moving towards parity , and this is an excellent example of that ten years ago , the better teams were better and the worse teams were worse relatvie to the average NHL team than they are now . The fact that you can use the same stats for the Oilers ignores the context of the league and the other teams in it , and that ' s why it looks like I ' m not really making a point .
