It looks like I have a few bad lifters in my 1999 3.9 v6. I have read many old postings and it looks like I can spend $115 for stock lifters or over $300.00 for Performance Lifters.
I apologize if this is a repeat question, BUT will the performance lifters be worth the extra money??? I thought lifters were just lifters. I'm not sure how you can get extra performance out of a lifter.
Any creative input is appreciated. Thanks in advance.
Flamers go away.......:)

If anything, the tolerances might be a bit better in the MP units, but it's just not worth the $. You could gain a lot more performance taking the saved money and applying it towards a cam, or some other upgrade.

The mp units and the stock units are the same thing.
for 300 bucks you must be talking about the crane units, they are not woth the price difference in your application

GO TO mopartsracing.com, dodge dakotas section and you will find slightly better than stock performance lifters for $110.50...
Part number 5249862 --- this is the v8 set so you'll get a few extra :))
And these aren't stock, because I've compared the two as I was putting them into my 99'... Their not all out performance lifters, but are slightly better than stock...
To start with what exactly makes you think you've got bad lifters??? These are roller lifters to go with the roller cams in these things and I've not really ever known of one to fail, but then again, I always use some of the best syns and so forths to keep the inside lubed well :)) The only thing in the magnums I've ever known to really "tick" is the junk non adjustable rockers and the junk fuel injectors that sounds like it's coming from under the valve covers, but it's really the injectors...
Hope this will help you out a little...

The performance mopar lifters sell for $114 at
the dealers that is for a set of 16
seporate for 12 is like $130 10 something each
when purchase seporatly
The performance lifters are designed to handle
a little more stres high lift cams and stifer
valve springs and work very well in the stock
3.9,s
Gaskets are around $35 intake and pletium sold
seporate does not come with intake set.
Also if you plan to replace the valve cover
gaskets get them from mopar the after market
gaskets are junk and tend to leak, the mopar has
a piece of alm in center covered by silocon and
are easy to instal the chep rubber ones move all
over and if you over tighten even a little will
pop out between the bolts and leak

Hey, Thanks for the good advice. I thought I would get flamed for asking repeat questions.
I am getting the MP lifters and will put the money saved towards 1.7 Roller rockers and new push rods. Everyones advice made that an easy decision. While I'm in there, I want to do it right.
Greg: The reason I'm changing the lifters is to get rid of a loud knocking noise it makes when it is cold or has been sitting a long while. It is a long story, but I bought this dakota a couple months ago and I feel the previous owner did not do a very good job with the oil changes. I saw all the signs but bought it anyway. I got a very good deal and I don't mind doing doing a few repairs. I hope this is the last though.
I bought it off of a used ford lot(LOL). They serviced it there and it had motorcraft oil and filter in it. Everything was fine for a bout 300 miles, then I noticed this knocking noise in the mornings and it got worse.
When I first start it up it is fine for the first 5 seconds, I have well over 50 psi oil pressure, then this knocking noise slowly starts. It's not a ticking or a tapping noise, it's a knocking noise and it's embarrassing as h@ll. I can walk across the street to my neighbors house and hear this knock.
It will do this for about 3 to 4 minutes until it starts to warm up, then it sounds fine and always runs fine.
I have flushed the engine multiple times and it is better now but I give up. I'm going to fix it right. After I flush it and change the oil I cut open the oil filters and find some very small pieces of black crusty burnt oil. Signs of crap oil from the previous owner. I feel that the crud broke loose and caused the problem with the lifters.
I was using castrol 10w-30 (cheaper) and various additives trying to clean it out. I would run it a few hundred miles, then run a flush again. After 5 flushs (LOL) I said no more and decided to try something I read on this board.
As a last chance I put in amsoil 0W-30 and a sdf-42 filter. I have to say that it has helped alot and has very good oil pressure, but it still makes that noise.
Oh well, new lifters, push rods and 1.7 RR's will make for an entertaining afternoon.
I have amsoil fluids in the whole drive line, I've been using amsoil since 1981.
Also, it is a 1999 3.9, CC, auto, 4WD, 88K miles.
Sorry for the long winded post.
Larry, you are right about the mopar valve cover gaskets. I pulled one valve cover to look inside, then cleaned the gasket, put it back on and no leaks. Nice set up. I will replace them next time.
Thanks again.

are you sure that this is not the timing chain knock. It would be a shame to do all that work for nothing. because they are roller lifters they do not go out very often but the timing chain knock is very common and can be cured by adding a tensioner.

There is no difference in the mopar performance vs stock replacement lifters other than the stock replacements being more expensive. If you look in the box the MP ones come in it even states that these are just 94/95 mopar oem lifters. For some reason the 94/95 ones were better than other years, heavier spring maybe? Its not anything noticeabl though or mopar would of kept that 94/95 lifter design in production for all years. If you sit the oem and the mp ones next to each other they are identical....
