A lot of hydraulic roller lifters have a disc that has a tendency to break, it's underneath the pushrod cup. The broken disc can now move around and block the oil hole. The lifters works but won't oil the pushrod.

This is not a great idea. Having an open circuit on the ignition secondary side drives the voltage sky-high; leads to problems with insulation--it's hard on the plug wires, cap, rotor, and the coil including the insulation on the internal windings.

MUCH better to GROUND the spark in order to kill each cylinder in turn.

Blunt the sharp points of eight small nails. Lightly lube the nails with silicone dielectric grease, then slide the nails between the plug wires and the distributor boots. You'll feel the nails touch the metal end of the plug wire. DO NOT puncture the insulation.

Then touch each nail in turn with a grounded jumper-wire or 12V test light (the lamp won't light up.)

No high voltage, no insulation damage.

I had plug wires grounded to header. So spark had a place to go

Title and pic says it all

[Formulas]

Well hey now you can build back better, That sux ya figure bearing material ?

[johnta1]

I think you know why the lifter didn't work?

Sorry to see that.

[Schurkey]

What are you showing us? There's no reference for size; that could be a cup of Starbux coffee with melted whipped cream, and a goofy-looking "sprinkle" on top.

No, the title and pic DON'T "say it all".

[77 TRASHCAN]

Yeah...is that a Latte, or hot chocolate?

[slowbird]

That is the bottom of the cut open oil filter.

[tom s]

Looks like sand?Tom

[dataway]

Assuming that is iron/steel and not bronze or copper? Trash from assembly? Oxide from a rusty block?

I guess either one is not good.

If you do a rebuild .... get some niobium bar magnets and stick them around the circumference of the filter housing. Then when you cut filter open the ferrous material will be stuck to the housing walls and the bearing materials and other non-ferrous particles will be in the bottom.

I typically leave the magnets on all the time to help keep very fine metal particles out of the oil.

Is this a follow up to your other post on

Thoughts on knocking sound??
If so, Dam that too bad. Sorry that happened to your engine. Can you give us more on the cause. Oil doesn't look so good for sure.

One I find out the root cause of the copper/brass I'll let you know. But my guess is either the cam gear is chewed up or a bearing.

[25stevem]

I don’t believe Brass is used in the make up of modern replaceable bearings.

Time to yank the dizzy and look down at the gear.

[Formulas]

if its bearing material could be main thrust bearing easy to check without tear down by looking at crankshaft endplay

pry crankshaft fore aft should be easy to spot excess without a dial indicator

There's really no title needed for a pic like that.

[NeighborsComplaint]

Before you spring into action get your bearings ... OK sorry for both the puns and your misfortune.

Without rereading the whole thread, was this a Hydraulic Roller camshaft lifter?

Manufacturer?

Hi Tom

It is a HR camshaft and lifter set that came from Competition Cams
