Hyd lifter valve lash adjustment

I think I sat the valve lash this weekend, tell me if I did wrong.

Rotated the piston to TDC.
Tightend the rocker until I felt slight drag on the pushrod.
Then went 1/2 a turn and locked it down. (I figure 1/2 would be ok for break-in)

Repeated this step on all 8 cylinders.

Did my question not make any sense, or did I do it correct?

not a fan of the way you did them . check one cylinder with the e. o./ i.c. way. note how much difference the adjustment (if any) is. if same or real close - be good to go.

I couldn't remember how that went so I just did TDC. So when the exhaust starts to open, check the intake. Then when the intake starts to close check the exhaust?

Which cylinders can you check at the same time? If I remember correct isn't there away to check all the cylinders by only rotating the crankshaft to 3 places?

Thank you!

...there is. I saw it in my Ford factory sevice manual. Don't have it memorized tho.

jones that is how i have always done all mine and have never yet had a problem

Which way? The way I did it or the other way?

the way you done yours then i put the drill back on the oil pump and pump oil through them and rotate the motor if i have a someone helping you run the drill and rotate the motor 4 or 5 full turn and recheck them and if they still rotate good drop the dizzy in and i fire it up and bring it up in rpms and let run for cam break in this is how i do mine when breaking in a cam never had a cam whipe a lob yet then i put the inter spring back in if it has inter springs and redo the rocker again hope this help i know some don't like way this but has always worked for me

I've always done my hyd. cams the way you did it Josh without issue. I would start @ #1 on TDC, and adjust both valves, then just went through the firing order until finished. Only when I tightened mine, I would only run them @ 3/8 turn, 1/2 turn max. I've even done smallish solid F.T. cams the same way without issue. But, it doesn't take any longer to do it by I/O E/C method than it does this way. If you're doing the I/O E/C method, you are correct by checking the intake when the exhaust valve just starts to open, but you want the intake valve about 2/3 closed before you check the exhaust.
Sounds like you're gettin' closer.




Doug...

Thanks guys, I hope to sit the engine in the truck this weekend. That is if I think I can install the oil filter relocation kit with the engine in the truck. The only thing I really lack is a transmission and converter. I don't see myself being able to afford those until the spring.

I have purchased a factory serp bracket setup from Gregp, bought a B&M Pro Ratch shifter from a local and only lack fuel line and fittings for the fuel system.

Per Tom Monroe's How to Rebuild Ford V8s... pg 118

Point A - - - - No. 1 @ TDC (end of compression stroke).

Point B - - - - Rotate crank clockwise 180* (half turn) so point 2 lines up with pointer. I believe this is a typo, and should say "so Point B lines up with pointer".

Point C - - - - Rotate crank clockwise 270*(3/4 turn) until point C aligns with pointer.


429/460

Point A
No. 1 intake _ No. 1 exhaust
No. 7 intake _ No. 5 exhaust
No. 8 intake _ No. 4 exhaust

Point B
No. 5 intake _ No. 2 exhaust
No. 4 intake _ No. 6 exhaust

Point C
No. 2 intake _ No. 7 exhaust
No. 3 intake _ No. 3 exhaust
No. 6 intake _ No. 8 exhaust


Hope this helps.

TDC method is ok for that deal. Big rollers it can make a diff.

longroofracer,
Thank you!



richter69,
I kinda figured that using the TDC method would depend on how extreem your camshaft is. I know for a fact that both valves are closed durring TDC. Being that the lifters are collapsing you have to really pay attention when the valvetrain gets tight. Breaking this camshaft in is going to be interesting or a roll of the dice.
