Review on 🔧 Dorman 615-178 Intake Manifold for Ford, Lincoln, Mercury - Engine Component Selection by Sean Liu

This fixed a leak in the thermostat housing on a 4.6 liter Ford engine on my Lincoln. This is a common problem with these engines and was the most economical solution. I wanted to do the installation myself. but after thinking about it, the mechanic did it instead (I've done enough idiots in my time, and now that I'm older I didn't need to get frustrated!). I also bought replacement o-rings for the fuel injectors and it has worked fine on older engines. From what I've seen a part that looked well constructed with integrated gaskets and a metal coolant transition front, hopefully it holds up? The mechanic said it was good except that the brass inserts were replaced with self tapping threaded holes but it all worked out fine. The book estimated this at 5.25 hours, a professional installation would probably take all weekend, but it's easier and less frustrating to have someone else who knows what they're doing do the work! Plus all the unknowns you come across with old cars! So far everything works fine! Buying from Revain was about $50 cheaper than local auto parts stores! Hope this helps DIYers!
