The "base map mail order sct tune to get it moving" isn't for "gave it alot" type of efforts, that's just asking for trouble... Link to comment Share on other sites More sharing options...

If it is then farken farkers farked. If it doesn't do that then you'll likely be in the clear. While it may have just been a pumped up lifter, there's also a good chance you broke a ring land. If you've got the gear, give it a compression test. 2 Link to comment Share on other sites More sharing options...
