Is A Boxster Too Big Of A Risk

[Jake Raby]

Being a 99 model your biggest concerns are:
1- Slipped sleeves- we seldom see this MOF these days, its seems that all the weak engines have already failed and have been replaced. I have only had one failure call this year where someone had the symptoms of a slipped sleeve.

2- Cracked heads- This MOF is quickly becoming the most poplar with pre- 2002 engines in the 996 and pre 2003 in the Boxster. The best way to avoid this MOF is to change the water pump before it starts to have chipped impeller blades that end up in the cooling system and creating hot spots and cracked heads due to them.

The IMS is certainly a real possibility.
