Well, just finished up converting my Beetle to synthetic engine and tranny oil. Put a Passat oil filter on also. Pulled the oil pan, to check for crapola in the pickup tube, and in the bottom of the pan, and was pleasantly surprised to not find any. All went well, other than I forgot to put the boost tube back on the air cooler...it doesn't run real well without that FYI...But alls well now, just ran out of time to get a piece of exhaust put in place of the resonator. Does anyone know inside ID of the pipe? I would like to get my supplies before tearing it apart.
