Fiabilité Porsche 911

3.8s are notorious for having scored cylinders on the ones further away fromt he waterpump.. so 4-5-6. Easy way to tell is massive oil consumption and a greasy left rear exhaust.

I suggest getting a lower temp tstat either way

bad waterflow design? too hot in that area?

Yea something like that combined with the pistons being too large. Wrong material etc. Creates a hot spot. We were told in training to specifically get lower temp thermostats


some light scoring is normal.. the bad ones will start burning oil, soot on left tip.. then the knocking or clacking will start. Non ferrous metal in the oil filter canister. Do all of them do it? No but there is a good amount that do. Some people got lucky and had new engines installed under warranty 1-2 times.

I cannot stress enough a proper PPI on Porsches including an overrev report either from PWIS or Durametric.

Also low mileage cars scare me vs a well maintened example that has been actually driven. I can tell a crap can from a mile away just by how it sounds...
 
si je regarde la fiabilité de subaru avec leur moteurs à plat, j'ai des doutes sur ceux de porsche.

ca doit etre mieux étant donné que cest plus solide mais je serais craintif un peu.. je ne parle pas en connaissance de cause pour porsche mais subaru j'en sait quelque chose...

C'est pas le moteur a plat le problème, c'est Subaru.
