This is a closeup of the multi-finger tool mentioned earlier, its a spring loaded plunger type design that comes in different lengths, this one is 28".

The tool shown below is the telescopic wand with magnetic pickup, these two tools will save you a lot of grief.

...sorta reminds me of my x-wife's lawyer.

Jerry is right about everything. Yes, the lifter can be removed without pulling the intake but I think he is also right about checking the cam. To remove the intake is not a big deal in fact I would argue that you could probably remove the intake and replace the lifter as quick as you could by fishing one out.

Do yourself a favor and take the time to do this right. Things can get expoentially worse if you do it wrong.

Easy to do on number one. The magnet or claw tool will get it done. Even easier if you pull the distributor because it will let you put some light down there and give you a place to slip in another tool/access hole if you need it to get the lifter out.

Look at the lifter pretty close once you have it out - - it can still have a break-in failure even after the pre-break in service. If it looks perfect externally - toss in a new one butterred up with the appropriate cam sauce and get her going.

Cam Dynamics isn't a miracle worker. I've heard of several people that have had break-in problems after Cam Dynamics broke in their cams.

were the problems on the front/back lobes????like maybe they didn't get enough lube on the end of cam during the prcess???

yes they are factory non adjust. to shift the thread alittle maybe "wicked"
can take this under advisement. to put adjustable rockers on a hydraulic cam
for street use defeats an advantage of a hydraulic cam and also opens the door
for other serious issues. the beauty of the fe hydraulic rocker system is the
ease of valvetrain to work on. the lash is pre-engineered in. if there is a height
problem in the original build that the factory arms dont work the eaisier and cheaper route is to use custom length pushrods, which maintains factory
rocker geometry. again let me qualify street use. the factory arms and shafts
are strong they withstand high rpm the only cases in which they do not hold up is high profile roller cams, spring pressure breaks shafts.
in retrospect having to predetermine lash using adjustable rockers on hydraulic lifters is touch and go. lifters pumpup with oil pressure if you adjust lash without the engine running you may over preload the lifter causing,
(get this wicked) a collapsed lifter or wiped lobe or bent pushrods or all of the above. all this is good but in building an engine for a car the best
advise is be honest with yourself on "what will the car be used for"
if its a street car build it for the street (drivability) if not then what rpm
does the engine make peak power. in this case its a 428 wicked hasnt
listed any other info about his build so i will assume mostly stock
the intake manifold is probably his limiting factor. around 6300-6500
rpms well within the limits of the factory arms and shafts for a hydraulic cam
so wicked ask yourself do i want to change lifters all the time? or set it and
forget it?:confused:

now that i have blabbed so much i need a beer

Good Luck. Just had a similar problem with my 428. Periodic lifter noise got worse on number 5. I too thought it was just a collpsed lifter. When we got into into it there were 4 mushroomed lifters and 4 rounded lobes. Melling camshaft. Engine run-in by the builder and also run-in by me when the car was assembled. Oil changed 4 times in 2800 miles. Fortunately, when I decided to fix what I thought was a collpsed lifter, I also decided the car "needed a little more cam" so I dropped by to see a friend of mine (local FE expert, has a machine shop and also an original GT-40) and he put me on to Chase at Crane Cams. Chase speced a road race grind for my engine and drive train. With new lifters about $300 Gazoutas. (Goes outa my pocket). Car is now back together. Just put 100 miles on the new cam and just changed the oil. As a side note, the car is just a bit louder with the new cam and I just moved into a new town house. Neighbor upstairs came down when I fired it up in the garage and I thought she was going to complain. She almost started to cry. Seems her high school flame had a "Real One" and it brought back a few memories.

Well well...
 

Turns out a lot more serious than I hoped for.

Pulled the lifter last night, junk.

Look's like I will be pulling the pan and changing the cam.

Thanks to everyone for ther sugeestions.

Best,

I know, more $$ but the hydraulic roller's the way to go.

Dave

I sure would like to know what caused that. Crappy lifters? Oiling problems?
