Oil weight for engine ticking in a 360FE??
I have a ticking sound coming from the engine in my '75 F250 with a 360FE. It's only on the driver's side and doesn't go away. I'm assuming it's a ticking valve lifter. I'm running Castrol SYNTEC 5W-20 in it right now.
I read on the Castrol website that the newer synthetic 20W-50 is formulated for classic engines with flat tappet camshafts. Will this sound go away if I switch to a Castrol SYNTEC or Mobil1 20W-50 synthetic oil? I don't put that much mileage on the truck, so I want to stay away from having separate winter and summer engine oils. Thanks!

I always thought those 70s V8s were supposed to run a 40 weight. I would never run a 5w20 in that engine. What oil pressure do you get on 5w20?
Also, 20w50 may be/likely is too thick. Your best bet is a HDEO 15w40 like Valvoline Premium Blue or Shell Rotella. If not that, at least a 10w40 for winter, like Maxlife.

I never has a a problem with my oil pressure. I'm assuming my oil gauge is operating correctly. Oil pressure varries between the "O" and "L" in "OIL" on the gauge. "L" and "H" are on the extreme ends of the gauge range. When I idle, oil pressure is close to the "O" and when I'm driving normally, it rises to the "L" level on the "OIL" gauge label.
I thought that if you used synthetic oil, you could use a lighter weight when compared to petroleoum oil because of its physical properties. Maybe I'll try a 10W-40 and see how my oil pressure gauge responds to that.

Something worth trying in an FE is adding a quart of transmission fluid mid way between changes. If that doesn't do it chances are good that you'll have to replace a lifter. As for oil, I've always used 10W-30 or 15W-40 in FEs. Once upon a time it was straight weights only, but I hardly use 'em outside of air-cooled engines.

I used this with 5w20 oil but Ford has not authorized your vehicle to use 5w20 oil as mine has been.

Well I see your in Pa, so my old 78 Merc manual says 10W-30 would be a year round choice.
Maybe a dual rated (gasoline/diesel) lube, that has higher levels of zinc & phos in the add pack, for the flat tappet lifters.
Several lube mfgrs make a recipe that'll be friendly to your flat tappet Fe engine.
As has been said, the 5W-20 really isn't specified, nor formulated for your engine type.
