thanks for all your words, the normal perception about sleeves is not good, but there are so many factors in determining whether sleeves would work or not, we have put sleeves on around 100 engines, only a few troubled, we have discovered the best quality of sleeves, and in the past few engines, they have not troubled even after 5 years of use,
the main reason of trouble are quality of rings and sleeves, and the headgasket thickness not being according to the skimming of the head..
in my case i have put in top quality sleeves, top quailty german rings, original peugeot headgasket , the same thickness which was fitted to the engine when it left the factory.. and the head has not been skimmed, so there shudnt be any problems,..
The idle running and initial running period also is an important factor.
