Default Lifter/Rocker Arm adjust?

Just out of curiosity, is it possible to adjust the rocker arms on the rocker arm panel? the only thing I remember when I put everything back together were the 4 bolts that held the rail to the head

I have a lifter tap on cylinders 1 and 3 after the engine is warmed up after 15 miles of driving and its driving me crazy.

Also, is it possible to replace lifters without taking out the heads?

Not adjustable. IF you need lifters, you need a cam.

Well i had a tap for a few months and thought it was the rocker arm. When i opened it up it turned out to be a bad lifter. I just bought all new lifters, i didn't see a need for a new cam. While I was there I did install the 4.6 ford injectors. Made one Hell of a difference. Between new lifters and injectors it woke that engine up! She runs so smooth and quiet I can hear the injectors poping! At a stop light i have to look down to see if she is still running its so smooth. I Did the work at 95k. I now have almost 115k.

haha nice! I just removed the Intake and checked my lifters

Every lifter on the left bank (noisy side) came out nice and easy, except the exhaust and intake lifters on cylinder one (main noise epicenter)

...I have 3 lifter with little marks and the I think now the main culprit was the cylinder one baddy as it has impact marks

I checked the cam and the lobe was not worn down and it looked normal...I just feel like an idiot for not checking the lifters when I did the head gaskets but hey...at least I know more about my vehicle right!

I'm getting some lifters after I measure the cam...hope that does the trick

Can you give 6 bullet point description of lifter change? I'm trying to get an idea of what it takes. Thanks.

Clean your engine! Nothing worse than getting crap and debris inside the engine
Drain coolant
Remove upper intake plenum
undo the coolant hoses to the heater, move em outta the way
mark all electrical connectors
Relieve fuel pressure and disconnect the fuel lines, move out of way
Remove lower plenum, it'll have two curved pieces of metal at the valley, dont forget the single bolt on those guys.

Remove the valve covers

Remove rocker assemblies

Remove lifters and finally the pushrods.

intake bolts I think are 13mm.
Grind down a 5/32nd 12 point and you can use em on the valve covers.
The big intake gasket can get a little sticky so it might take a little force to pull the lower intake manifold out.
Dont forget to mark everything and keep it CLEAN!

Replacing lifters and not the cam is false economy.

It won't be long until those new lifters will wear your cam to nubbins.

False economy, I will have to add that to my goodie bag haha

But yes the cam needs to be at least measured/changed if you do lifters...

I have only heard horror stories and judging how the previous owner treated MY Rover I wouldn't put it past anyone else to have taken a shortcut with yours (general public)
