How to remove the Valve Train of a 200 inline 6?

[JMB]

I was thinking of removing the whole valve train (rocker arm assembly) to be able to clean it due to heavy sludge build up.

Can anyone tell me "how" to do this? Any procedure, tips, advice or ideas?
Thanks.

Once you get the rocker arm assembly out and cleaned up you might want to look at the underside of the rocker arm shaft. The shaft seems to be prone to galling.

remove valve cover.unbolt rocker shaft.remove.leave pushrods in and remove them one at a time to clean so they stay in the same hole.

Thanks for the reply guys.

early ford fan,

Is it the 6 main bolts that are located on the top of the valve train that I have to remove to remove the whole valve train?

Also, when installing the valve train back , ( How Tight) how many foot pounds of torque is requiered on the bolts?

Is there a sequence on tightening the bolts back down? Thanks.

Yes, the top 6 bolts. Torque is 23-25 ft-lbs. I just snug them all down in increments, in a spiral pattern from the inside.

wallaka,

Thanks for the info.

Can I spray some Carb Cleaner on the head to clean the rest of the Sludge buid up?

Cuz it is easier to clean the top of the head now with the valve train removed. Thanks.

You could, but be sure to wipe up the residue well. You don't want chunks of stuff falling into the oilpan.

Howdy JMB and All:

I recommend that you change your engines oil too, if you're going to use carb cleaner on the top end. Carb cleaners are very NOT friendly to oil.

Are you working with adjustible or non-adjustible rocker arms?

Also, FYI inspect the top ball end of each push rod for any wear other than a nice shiney ball. I've seen ball ends with a mohawk ridge wear pattern and a nipple protrusion. Be sure to remove the cups on the end of the rocker shaft and clean the inside of the shaft. I used a gun barrel cleaning brush and rod, with lots of cleaning solvent to clean mine. Also check and clean the two holes on each rocker arm. As you view a rocker from the side, the holes are located at 10 on the valve side and 3 o'clock on the pushrod side. A 3/32" (Pushrod side) and/or an 1/8" (Valve side) drill bit makes cleaning the holes an easy job. On '70s and later non'adjustible rockers both hole were the 1/8" size.

Hope that helps.

Adios, David
