Petersubaru Posted August 11, 2006 Share Posted August 11, 2006 yesterday, I replaced the coolant and oil hose under the turbo and I was wondering how to judge the condition of my turbo..apon looking at it, there is no oil to be found, everything seems to be clean... the blades spin freely and have only some sort of gray matter on them with very, very little side to side movement...'86 EA82/206,000miles/oil changed every 3000mi since new Quote Link to comment Share on other sites More sharing options...
mikeshoup Posted August 11, 2006 Share Posted August 11, 2006 If you didn't feel really any shaft play in the impeller, all is good. Just remember to idle the engine a minute or two before turning it off and it should last long into the future. Quote Link to comment Share on other sites More sharing options...
rllywgn Posted August 11, 2006 Share Posted August 11, 2006 if its clean inside thats typically a sign of a good turbo as well as having no shaft play.. you can also check to see if it has any inwards/outwards. you can also check the the aluminum peice from the turbo to the throttle body for oil residue.. if it's all clean thats typically a sign of a good pcv system and turbo. rllywgn Quote Link to comment Share on other sites More sharing options...
Petersubaru Posted August 13, 2006 Author Share Posted August 13, 2006 there is no noticeable play in the shaft when pulling or pushing the shaft inwards... if its clean inside thats typically a sign of a good turbo as well as having no shaft play.. you can also check to see if it has any inwards/outwards. you can also check the the aluminum peice from the turbo to the throttle body for oil residue.. if it's all clean thats typically a sign of a good pcv system and turbo. rllywgn Quote Link to comment Share on other sites More sharing options...
4x4_Welder Posted August 13, 2006 Share Posted August 13, 2006 Do the blades have a sharp, straight edge, or is it jagged? Quote Link to comment Share on other sites More sharing options...

baccaruda Posted August 13, 2006 Share Posted August 13, 2006 sounds like you're in luck. read about turbo timers for more on pre-shutdown idling. Quote Link to comment Share on other sites More sharing options...
