Phill Gent Posted October 22, 2019 Report Share Posted October 22, 2019 Hi does anyone know how to decipher Porsche boxster engine numbers mine is 62s01916 I am trying to find out which engine it has and if I should be concerned about the IMS it is a 3.2s Jan 2005 with 38000 on it. Any help would be welcome. Thanks Link to comment Share on other sites More sharing options...
Tubzilla Posted October 22, 2019 Report Share Posted October 22, 2019 From the date I would say it is single row. Link to comment Share on other sites More sharing options...

jimmy p Posted October 22, 2019 Report Share Posted October 22, 2019 Can be, there is no exact science with it. I worried myself about it years ago enough to go and get a Porsche warranty on a 3 2 05 plate car. Never had any issues. Depends how risk averse you are. All 3.2's have same bearing Link to comment Share on other sites More sharing options...

All 3.2's have same bearing Don't think that's true, they switched from the single row bearing with the high failure rate sometime during 2005 to a slightly larger single row bearing before it was designed out with the 987.2 in 2009, so plenty of 3.2 have the larger single row bearing which seems much more reliable, but cannot be replaced without splitting the crankcase. 1 hour ago, Phill Gent said: Hi thanks for the reply,do you know if that is the problematic one . It seems pretty likely that you have the small single row bearing with the high failure rate, but the good news is that it's survived ok until now and if you are really worried, you can get it upgraded. Cheapest to do it while you have the box off for a clutch. Link to comment Share on other sites More sharing options...
jimmy p Posted October 22, 2019 Report Share Posted October 22, 2019 They changed the bearing sizes on the 997's but I dont believe they did on the 987 3.2's, they just got changed to the bore score 3.4 engine on the gen 1 cars which may of had the newer bearing. Check with cmoose on pistonheads as he seems to of done the most research on this. Link to comment Share on other sites More sharing options...

I checked what Cmoose had to say and it is essentially that it has not been proved to his satisfaction that the IMS changed at the same time as the cover plate did. Others on the thread have confirmed an updated engine number reflected an upgraded bearing when inspected. Not sure why he's pushing this theory so hard, but there is a big industry in the US fitting IMS 'solutions'🤔 Richard Hamilton seems like a pretty solid source of technical info on Porsche, but always interesting to hear other opinions🙂 Link to comment Share on other sites More sharing options...
