oiling system mods
Most people recommend installing screw in oil gallery plugs instead of the press in plugs for safety.
Also on some Mopar engines it seems common to drill a small hole in a plug behind the distributor gear in order to provide adequate oiling for the gears. I've seen some people recommend this for the sbf too. Makes sense to me, especially when using a roller cam. Are there any known drawbacks? The one to drill would be on the left: http://mustangandfords.com/techartic...mage_large.jpg What screw in plug size fits the bores? Simon |
3/8" pipe plug

Although I don' really see any advantage to it, I can't see that it would hurt anything. AFAIK, there are very few people doing this to SBF's. And yet, I almost never hear of an early timing chain/gear failure.

If you don't drill the hole, then how does it get lubed from the factory ????

I've seen it on BBC's.
On Fords, I don't do it, I just tap the galley plugs for threaded plugs. The timing chain should get lubed by oil splash. |
It actually squirts on the distributor gear, not the chain.

My idea was to drill the plug at an angle so the oil will squirt directly on the meshing gears as shown in this sketch: http://img844.imageshack.us/img844/8533/camgear.jpg I hardly found anything about this modification on the internet, that's why I wanted to hear some opinions. |
The galley plug your talking about is a plug on the oil galley that feeds the lifters. I don't think it has anything to do with the cam gear and distributor gear, drilling the hole in it will shoot oil on the backside of the upper timing chain gear, the splash from that will lube where cam gear/distibutor gear mesh....otherwise, the cam gear/distibutor gear are lubed from the oil slinging off the crankshaft at the #1 journal....
I'm not sure you could drill the hole at enough angle to directly shoot oil on the cam/ditributor gear... It can't hurt to do it though and I do it on my engines just for adding oiling.... David |
