Yeah I know, but they are all getting replaced now .

 

connecting a mechanical oil preessure gauge would be helpfull to diagnose.....

 

I'm curios how much does it cost to have a shop replace them , mine is shot too but its more of a cluck than a knock

 

so it sounds like a chicken??

 

How much to have a shop replace them?

At a dealer, expect a 4 hr job, so $80 times 4 = $320 for labour. Plus around $500 for parts. so at a dealer, expect around $820.

At a private shop, labour would be around $60 (that is in my area, just giving a comparison is all), so $240 for labour plus $300 for parts. So $540 at a private shop.

DIY is by far the cheapest. Parts are about $250. And a days work assuming all goes as planned. Heck you could do it for fun over a weekend.

Those prices assume you are replacing all 16 lifters. And they assume prices in my area!

 

500 in parts....?

Lifters are 90 off EBAY, toss in a few gaskets. Done.

Ever had a lifter apart? Not much to collapse, I don't understand that term when referring to lifters. I do know the lifters can come apart inside, doesn't matter who makes them or how many miles are on them. I'll bet everyone with a Magnum motor, regardless of miles or who made the lifter has lifters that the trunion cup has come off the plunger. Does it mean it's collapsed? No.

So where does collapsed come in...? I think a lifter has what, .040 of plunger travel? That's it collapsed or not.
But like Hillary said: "What difference, at this point, does it matter?"

But adding something like Sea Foam to an oil caked engine is a mistake. Big mistake.

 

$500 in parts. Yes from the dealer. Sure you could get them off eBay cheap. I never thought of that. I paid $215 for 16 of 'em from my local NAPA, and of course that's at a discount too.

 

There's only one or two companies making stock style Magnum lifters, no diff in them. I just bought the same lifters Summit is selling for 300 off EBAY for 90. Same darn lifter.

In my Dakota I use shimmed lifters, makes em like solid rollers and lets me spin it over 7K. But it's still a stock style lifter.

Being the lifters are Hydro, mabe the collapsed part comes from the clearances opening up allowing oil to push past the internals allowing the plunger to "collapse".

 

i got some DANA lifters from NAPA.

 

Be sure to do the 'ole drop test on your pushrods since you are there. They should all have a light "tink" sound to them, but if there is gunk in the oil hole, it will make a noticable "thud" when dropped (from a short distance of coarse... not enough to damage them) That can also be the culprit of the "lifter" noise.
