How to agust tappets on a 250 pre cross flow ford 6

Could b out just 1 toorh.(or 180°)
that (is it a 'over head cam"?) try moving the distributor alll way one way and try 2 Start it..and then the otherway can i have exact model. i can tell you what problem is.. did you leave all the spark plugs the same. 1342 is the firing order on (4 "Cylinder more info if ya can. cheers!?

easy capri laser?? ford , 4cyl in line --- 1 down adjust 8 =9
1 down adjust 7 =9 and so on 8 down adjust 1 =9 whatever you adjust the numbers add up to 9 ,ford laser capri then tappet settings used to be something like 14 inlet and 18 exhaust but as no doubt the rocker fingers are worn and the push rod cups the 12 and 15 may be better

Solid lifters and/or manually adjustable tappets? Now you are making me feel old. Well, if you have something that old, the way it is done is to use feeler gauges to check the spacing between the tappet and the push rod when the valve is fully closed and the cam lobe for that particular valve is not pushing on the rod at all. Many of those old tappets had a slot for a screwdriver so you could turn them to make the adjustment, and then lock them in place with a wrench by tightening the binding nut onto the rocker arm (tappets are mounted on the rocker arms). Obviously, all of this has to be done with the rocker arm cover(s) removed. That means that before you start, make sure you have a fresh gasket for the cover on hand. You will never get a used gasket to seal a second time.

2.9L Engine
No periodic valve lash adjustments are necessary on this engine. The engine utilizes a hydraulic valvetrain to automatically maintain proper valve lash. However, some earlier models have an adjusting screw on the rocker arm, which is used when assembling the engine to properly preload the lifter. If the engine has been disassembled, and the valve train parts were not kept in order, or there is an audible sound from the rocker arms while the engine is running, perform the adjusment procedure below.
The following procedure should be performed on a cold engine.

1. On the cylinder to be adjusted, position the cams so that the tappets are in the base circle area.
2. Loosen the adjusting screws until a distinct lash between the roller arm pad and the valve tip can be noticed.

The plunger of the hydraulic tappet should now be fully extended under the load of the internal spring.

1. Carefully screw in the adjustment screws until the roller arms slightly touch the valves.
2. To achieve the normal working position of the plunger, screw in the adjusting screw 1 1 / 2 turns, equivalent to 2mm.

If you have adjustable tappets bring the engine to top dead center no 1 piston firing The rocker will be on the back of the cam lobes. Inlet .010" hot exhaust .012" hot and then turn until next firing piston is in position. Go by firing order. I suspect that a 1997 model would have hydraulic adjusted tappets which means no manual adjustment. If it is rattlly I would be checking for worn rocker shaft and rocker bushes.

put the rocker arm on get lifter on backside of cam ajust pushrod so rocker tip is in the center of valve then measer pushrod

THE HANDIEST WAY TO ADJUST THE ROCKERS IS TURN THE ENGINE MANUALLY UNTIL THE ROCKER ON ONE CYLINDER IS GOIN DOWN THEN U CAN SET THE ONE BESIDE IT DO THE SAME ON EACH CYLINDER

When setting tappets, it has to be born inind that the valve stem wears an indentation into the face of the rocker. This prevents a really accurate tappet adjustment, so the customer is right again. If you do not posess a tappet setting dial gauge, a normal engineers dial gauge will do just as well. The procedure is the same as using your feeler gauge except that you set the dial gauge up on the cylinder head with the pointer resting on the head of the rocker. Press down fairly firmly on the rocker valve end and zero the gauge. Next lift up on the rocker and read off the clearance, from the gauge, Use a magnetic base to support your gauge and repeat the pocedure for each valve pair.

did u soak the lifters in oil 1st before installing them? if they are pumped up u bring that cylinder u are adjusting up on compression stroke, then adjust rocker to zero lash and then 1/2 more turn of the adjusting nut.

According to http://freespace.virgin.net/tommy.sandham/databook.htm# Rocker Adjustment, the cold clearance is .008" intake/.018" exhaust in the non-GT 1500cc, and .012" intake/.022 exhaust on the GT. Sweet little car!!!
