Plugs
Wrench,
6 plugs. Details on my build site: http://www.proefrock.net/3x2CSX/Engine/Block_Prep.htm Paul |
Go to threaded plugs
wrench 87 goto threaded plugs except for the back cam plug, Make sure this one goes in with the convex out and use RTV sealer so it doesn't leak. Use NPT plugs, drill and tap, make sure you clean out the motor before you assembly. I think there is more plugs than 6 for the oiling system, this depends on the motor. There are 4 that flank the cam bore, 2 in front of the block, 4 in back of the block. Make sure that you don't put them in too deep and restrict the oil flow. 1/8" or 1/4" NPT plugs are used, add a light coat of pipe dope to the threads of the plugs. Make sure area is clean. REMOVE and extra. There is an article about FE oiling system up grades. Put limiter in your oil feeds to the heads, depending on which rockers you use, from .070-.090 oriface will give plenty of oil and keep most in the lower end where needed most. Rick L.

Dont forget the one behind the distributor viewed from the front. The rest are easy to see.
Four in back around the cam, two in front at the end of one lifter galley and at the end of the center galley. In the lifter valley you'll have two for the lifter feeds, one for the vertical rear connection, and one for the oil pump cross channel. All can/should be 1/4 NP.T If you have a side oiler you'll get an extra four on the driver's side, and an extra one front and back for the side oiler passage. |
