Cleaning the heads and lapping the valves on a 2.8 V6 ford pinto

I took the engine apart some time ago and I am now getting to the clean and rebuild stage. The valves were shot.
Crack in the valve this was the worst one
I I loaded up my cart and got to it . Purple power from the dollar store did a surprisingly good job Ill spare you the details of scrubbing and spraying and having grease water and soap sprayed up my nose.

Then back to the work bench and I spent some time with the dremel and several brass wire wheels.

Now I need to lap the new valves its a simple process. get the tool the tool the compound and the valves and get to it. I watched so many videos of people who all claimed either they were experts or just guessing. Here is the way I do it. i cant say its the best way but it works.
1. clean everything with prep all or any wax, grease oil remover.
2.I use my gun cleaning rod and swab to do the valve guides
3. I put some compound on the valve on the lip then oil the guide and the stem.
4, Put the valve in and attach the tool.
5. I spin it until the noise changes and it gets quiet.
6. lift turn 1/4 turn and spin again until the noise stops. I repeat this 3 times on each valve.
Then clean and repeat on the next one. I test the work by dropping in both vales in the valve bowl  then filling it with fuel or alcohol. If they hold liquid with just the weight of the valve its done. Don't forget to put a spark plug in. As I said this is how I do it. I don't build engines for a living and my rebuilds have always been stock or just a small amount of  modification.

That is all there is too it keep the compound on the lip don't get it in the guide, I did a final clean with break-free and the gun cleaning rod , then coated it all with wd40 until i assemble it.

Please feel free to comment.

Rebuilding The steering Column

I changed the color of the interior in my 76 pinto to black, so I of course disassembled the steering column . I took pictures and notes and even looked at the shop manual for the car.
That was last year. Now I need to put it back together. In the mean time I did grease oil and paint all the visible parts.

I remembered to slide the lower part on first, as once you bolt up the collar where the ignition cylinder is, it wont fit back on. The collar has 2 bolts with flat tops that notch into the column itself. You will need to insert the one on the ignition lock release side before you slide it on, then the one on the ignition key once you have the collar on. Dont forget the rod that goes down the column to the switch this rod activates the switch when you tuun the key and cant be put on after the collar.

Then get help

Once you have successfully petted the dog and resisted the urge to go and sleep in the sun with him. Get column shaft through the collar and pull it as far as you can.


Now you will put the yellow clip on the column shaft just above the large threads. then the freshly greased bearing with the plastic sleeve over it. Ball bearing side down.

Then the blue snap ring goes on

Now push the shaft in until the bearing sets into the collar. the plastic sleeve will be flush.
To install the ignition cylinder ( this is a new one) I pulled the lock rod up to the locked position  and turned the key in the cylinder until I was able to press the locking pin in. ( new ones are ready to go.) A little jiggle and slide and its in. The locking pin pops into the hole when you turn the key. Check that the key will go to all positions and come out when the cylinder is locked.



Next is the blinker and horn assembly and the wire to the cylinder. Start all the screws and then start to screw in the blinker arm  then tighten the screws. I set the ignition switch to off and placed it on the rod hook and bolted it down. I tested the connections and done.
Then put the steering wheel on just to see how nice it looks. Now I just need to finish the car.



 I took a picture of the page in the shop manual to show the entire thing.
