1983 Ford 300 6 cylinder valve spring video

The day I recorded this, my uncle wanted to replace the valve seals on the 1983 Ford Econoline. So I decided to record it when he had the valve cover off to get the vavle springs while they were in motion. This van can be seen on one of my previous videos. The cat's name is Stretch.
The little explosion you see at the begging was caused, when my uncle put the ignition wires on backwards (he's use to his Chevy six cylinder which has more of a strait timing compared to the backwards timing on the van) therefore causing the engine to backfire through the carberator. Soon we put the wires back together and it ran like butter. The clattering you hear is from the rocker arms before they were adjusted. (That is what you saw my uncle doing in the video.) I decided to make this video fun and add some special effects. Enjoy!

Nice. Please adjust mine!

@woodsinme I wasn't the one doing the adjusting so I'd probably through your engine off, lol.

You said that your uncle is "used to chevy". Is that because the rotation of the distributor is backwards from the Ford? I know the firing orders are the same.

[KH990j]

@pskittle488 The distributor on his 250 I-6 in his '72 Chevy C20 (see related videos) runs a pattern that's opposite to the 300 I-6.

Sounds like a sewing machine!

Oops, forgot this part: 5. Repeat this procedure for the remaining set of valves, turning the crankshaft (6303) with an auxiliary starter switch, one-third turn at a time, in the direction of rotation. At the same time, adjust the valves in the firing order sequence, 1-5-3-6-2-4.

Pretty much you just follow the procedure below and torque the rockers to 17-23ft/lbs. By doing the procedure below, coupled with torquing the rockers to the aforementioned spec, you will be perfect every time. Doing the adjustment with the engine running is haphazard, at best; good way to take out a lifter or cam lobe. 25 years of race engine building has taught me this!

1. Install an auxiliary starter switch. Crank the engine (6007) with the key in the OFF position.

2. Make two chalk marks on the crankshaft pulley (6312). Space the marks approximately 120 degrees apart so that, with the timing mark, the crankshaft pulley is divided into three equal parts (120 degrees is one-third of the distance around the damper circumference).

3. Tighten the rocker arm bolts of the No. 1 intake and exhaust valves to specifications with No. 1 piston on TDC at the end of the compression stroke.

4. Slowly supply pressure to bleed down the valve tappet until the plunger is completely bottomed using Tappet Bleed Down Wrench T70P-6513-A. Hold the valve tappets in this position and check the available clearance between the rocker arms (6564) and the valve stem tip with a feeler gauge.

One of the best engines ever built... Love the backfire slow mo....
