Title: 3.6 LLT Timing Chain Issues
Post by: bladerunner on August 02, 2013, 11:18:58 am

Is there still on ongoing issue with timing chains on 3.6s? Anyone on here a GM tech who knows if the later models have resolved the issue? I have heard rumors to that effect and that the bulk of the issues were on earlier Lambdas (08-10).
