I read he horror stories, and I still what's going on. 3rd Ford truck and still impressed. 2 Rangers, now a 5.4 XLT Supercab 2006. No plug blow outs, no leaks, oil lifters etc. I do, however, after research and experience, think the 5.4 is a high maintenance engine. MUST use a light weight FULLY synthetic oil, K&N air filter, the correct oil filter, and CHANGE PLUGS at 60K. Run fuel injector cleaner every 3 fills. I only have 46K, but I really think preventative maint. is the key. Are some of you "romping" on these trucks? ie; break-stands, tug-o war?. Who knows, I may have all these problems at some point but I have never had one single malfunction/problem with ANY of the 3 I'v own
