ricky Member 39 Member For: 11y 11d Posted 28/02/14 08:20 AM Share Posted 28/02/14 08:20 AM Hay allTalked to a specialist today regarding our famous oil pump failures. Atomic have the oil pump gears and upgraded pump also. Ive seen alot off peoeple unsure off weather to get the whole pump or just the gears. Well the specialist says there is absolutely no need to replace the pump unless your revving the car to 8rpm. He said the atmoic guys are talking sh*t and just want the extra money. The gears are the only weak link.Cheers Link to comment Share on other sites More sharing options...

Possibly you are referring to the oil pump housings??Really only an issue in a manual from what ive found. The time spent on limiter in amanual, the stop start jerk that goes straight up the driveline to the snout of the crankcreates a hammering in the georotor. then kapow$$$. In an auto, the torque convertertakes a lot of the harshness out of it. Link to comment Share on other sites More sharing options...

Alot off people are just replacing the gears and the engineer I spoke to said atomic were talking sh*t about the pumps having issues only revving to 8rpm will cause pumps to fail. He said atomic are just trying to make extra money. Link to comment Share on other sites More sharing options...

I suppose your engineer has had more experience with Barra motors than Atomic 6 Link to comment Share on other sites More sharing options...
