If you will type:
Valve cleaning MTFCA
in your Google search window, the result will be many links to past threads about valve work. Maybe some of those threads will give you the information you desire.
And I recommend you not do a Google search for "jerking my valves".
I just finished a similar valve job.
I found 3 burnt exhaust valves replaced with new, new retainer pins, cleaned carbon and lapped the valves and adjusted the tappets.
Wow what a difference it made ... I have compression now.
I like the KD valve lifter, they lock in the open position which is real helpful. The old standard Ford lifter works fine in a pinch.
I have a quick question... How do you set the correct clearance if you dont have adjustable lifters? grind off a little of the bottom of the valve stem? what if you dont have enough stem?
Also, correct me if i am wrong, but if you are reaming out the valves, the type of valves you buy will decide how big to ream the hole. The valves you buy will either be
original diameter (.312"),
1/32 a.k.a..030 Oversize (.342)
or 1/64 a.k.a. .015 oversize (.327)
If your valves dont walk back and forth in the hole i would suggest not to ream out the guide hole as you cant put material back if you need to rebuild the engine in 30 years or so.
"How do you set the correct clearance if you dont have adjustable lifters? grind off a little of the bottom of the valve stem?"
If you don't have enough stem to set the clearance, you'll need to grind the seats a bit to set the valves lower, or get new valves.
If you need more clearance, grind the stem. If you have too much clearance you have a problem, you can reduce the clearance a little by grinding the face of the valve. I have also read that you can hammer the stem of the valve in the area below where it rides in the guide and "stretch" it some. I have never tried this last fix and doubt it would be very effective. Another solution would to put a little weld on the end of the stem and face it off.
only gonna use the ream to clean carbon only may need to grind the valves a little should know late tonite
i thought i had a old c-type spring remover,now can't find it, made some calls,no luck any makeshift way to remove the spings so i can work tonite on it?
Ronnie, go to Auto Zone and borrow one.
You have to buy it and then you can take it back within 60 days if you have the original receipt.
I have my machinest weld on to the end of the valve if the clearance is too great.
He does it with a small wire-feed welder.
You can use many different things. What I found one of the quickest is a pair of "pliers" designed to remove radiator hoses in one hand and needle nose pliers in the other.
Unless you actually want to change the size of your valve guides, keep the reamer away from them. Just clean the valve stems and use a bottle brush and some paint thinner, or other solvent of your choice, to clean out the valve guide holes.
