[QUOTE="Richard L, post: 1029652, member: 52972"] I think it is probably a cost-saving issue for Ford. Plastic is probably cheaper and easier to manufacture and the plastic parts will typically outlast the warranty period/mileage. Once the vehicle is out of warranty, it's no longer Ford's problem, it's the customer's problem...and if the customer brings it to Ford for repairs, it's a Win-Win for Ford. When timing chain rattle was a problem with some early model year Sport Trac's 4.0L V6 engines, Ford simply extended the warranty to 60K miles for the original owner. That only eased the concerns of the customer, but Ford knew that even with the extended warranty on the timing chain, they would still not see a significant increase in warranty claims due to timing chain issues. Like most other auto makers, Ford keeps very accurate records regarding vehicle repairs, repair parts and warranty claims....and know all the cost associated with those repairs. They can probably predict accurately predict, and probably have already done the analysis on just how much it will cost or save them over time, if they change the chain guides to metal rather than plastic. As long as the initial cost-savings out weights vs warranty repair costs, they will always go for the cost-savings up front. ....Rich ...Rich [/QUOTE]
