'79 Bronco Oil Weight

I recently bought a 1979 Bronco with the original 400 V8 and have noticed a ticking sound when the truck is first started cold. It last for 4-5 seconds then goes away. I'm running 20w50 and a FL1A filter. Is the oil too heavy for it?

Thanks

My Chilton manual states 20W-50 is okay if you never see temps below 20 deg. F, also shows 10W-30 or 10W-40 good for zero to 100 deg.

I would probably try 10W-40 at your next oil change and just see how you like it. It will protect you engine just fine and may pump to critical areas a little quicker. The downside is you may have slightly lower oil pressure once the engine is hot, depending on clearances.

I run 20w50 in my 78 Bronco's 351M but only because its wore out with oil pressure problems. Everything else gets 10w40 or 15w40.

I tried some 10w30 and it's slower to build up pressure according to the gauge but it no longer has the "no oil" sound that it had when running 20w50 cold

I've been running Chevron 15w40 diesel oil with Lucas oil stabilizer in my 79 Bronco with a 460. Its pretty much a dedicated wheeler so it gets run hard. No problems here!

A start up ticking sound would be heard in my older higher mileage Ford trucks when they needed an oil change. Changing it would solve this.
Running a thinner oil wouldn't be the solution to ticking imo.
How's your oil pressure?

It has the stock gauge and reads between O and A in normal

I wouldn't trust the stock gauge and really see what it is.
