Here in 2021, what are the best parts to use when doing a 4.7L valve train refresh in a 2003 Ram 1500? At 260,000 miles, the chain in my 4.7L is getting loud. So far I've obtained a set of HO camshafts, an HO intake manifold and a set of used 2005 or newer rockers with the smaller oil holes. Here's a list of things I still need and the questions I have:
1. What brand of timing set is best? Should I get one of the popular and very affordable sets from Amazon, or go with a US made set like Melling?
2. Is the "professional" Melling timing set worth the extra $80 over the standard Melling timing set for an everyday truck?
3. Do I need to replace the timing sprockets? Should I go ahead and get a timing set that includes them or wait until I get into the engine to inspect the old ones? Do they often need replacing?
4. I have the slightly newer style NGC engine. Should I go ahead and use a timing cover gasket or just use RTV like I believe came from the factory? I will definitely replace the crank seal.
5. New oil pump needed? Yes or no?
6. Any other things to consider?
My skill level is ASE certified Master Tech. But I haven't worked professionally in a shop since I became a college boy in the 1980's. I'm looking for advice specifically from folks that know and love the 4.7 and 3.7 engines. That advice is highly appreciated. And I will use it when purchasing the parts I need.
