Re: Initial start

Prime it with a drill. Cut down an old dizzy or buy a priming tool.

Re: Initial start

I usually disconnect the coil and crank the engine for a while.

Do not do this.

Buy a priming tool as stated above or remove the gear from an old distributor and use that as your tool. The most important part of the store bought priming tool is that it has the middle bushing to complete the oil galley to the top end. Some cheap ones only have the top bushing and rod. You can only prime the bottom end without the middle bushing.

Use a 1/2" corded drill to run the tool. Battery power will not do it. And install a mechanical oil pressure gauge to check that your bearing clearances are as should be. Correct clearances should yield you well over 50 psi on a new build.

Remember the camshaft lobes have no direct oil feed. The get oiled by splash only so it is important to get those RPM's up right when you fire it. Those first 10 seconds are critical, unless you have a roller cam.

No explanation, just don't do this? If assembled properly with lube and oil in the right places and the coil not firing so there aren't any loads placed on the bearings I don't see a problem.

Re: Initial start

This isn't a complete rebuild either just new cam lifters push rods and rockers so is it as big of that oil isn't coming out of each push rod

Re: Initial start

You need to turn engine stopping every 90º until you make a couple revolutions. It takes a little while for oil to come up through all the pushrods.

Re: Initial start

Did you run it for 20 minutes to break in the cam/lifters?

Re: Initial start

Put heat lamps on the oil pan for a few hours prior to a pre-prime. This will lower the viscosity of the oil.

Pumping that thin oil will be way easier and will also aid immensely in getting flow throughout the entire lube oil system.

For basically the same reasons, heat lamps should also be used if a cam break-in has to be conducted in an unheated garage - during periods of cold weather.

I'm going to be using one of these to do as you say and far more efficient than a heat lamp.
