- Most dealers (at least around here) charge between $200 and $250 for
- that job (Eclipse/Talon/Laser).

- Some Eclipses/Talon/Lasers have been snapping their timing belts early
- (the earliest I have heard was 1 yr/14k miles).

- Not so fast. If that timing belt snaps, get ready to spend
- $2500-$3500 on repairs.

-
- No. It is not freewheeling, just like the majority of the 4v/cyl
- engines out there today. The valves WILL hit the pistons. By the
- way... why are most 2v/cyl engines freewheeling and most 4v not? The
- Eclipse Turbo has a low compression (7.5:1). It seems to me
- compression ratio would be more of a factor than the number of valves.

-
- Oh really? You mean the few 4v/cyl engines made in the US and Europe
- are freewheeling? I know VW's are not. What about the Daytona IROC,
- Northstar V8, ZR-1 engine and the new Mark VIII engines? Are all of
- those freewheeling. (Oops! forgot the Quad 4 and the 3.5 on the LH).
