Lifter noise!!!!!!!!! WTF?

[turbovanman²]

Ok, after fixing my very noisey PS pump, I can know hear the lifters, and there very noisey, very, very noisey, so noisey there setting off my knock sensor. I seem to have good oil pressure as I am using my nearly new pump but I guess I could do an actual pressure test. I am using stock lifters and I can't see me getting 16 bad lifters. I just removed the front valve cover and all the rocker arms are loose. I checked the shaft and I did put it on right, and it is the right side so the holes are lined up. I started it and theres oil coming out of the hole on top of the rocker arm, not alot but some at idle so whats going on? Do I really have 16 bad lifters or is there maybe something wrong with the head?

Oh Snap!

[iTurbo]

Are you using any non-stock parts as far as the head/valvetrain go?

VanMan,

Are you running a regrind cam(s). If so are your shims correct?

Or is this a stock setup and you are new to it? Maybe you have some components mixed in from another engine, a 2.4 or such.

Loose rockers does not sound good at all. As you know torque down the cam caps will load the valve springs and the rockers could not be loose.

Since the addition of the regring cam in my car I'm putting in a set of FWD "high rpm" lifters as mine chatter a little at idle but get a bit noisy after a good 3rd gear pull but it clears up in a minute or less. I'm checking my shim sizes too when it's apart soon.

Good Luck,
Marion

How is your oil pressure at idle?

TurboJerry was playing with washers to act as 'side loading' shims. He had real success with it but he was just trying to quiet some of the ticking. He figureed out a specific sized washer, bronze IIRC. If you have real noise and the shafts are not upside down (you said the holes are lined up and you have oil) then maybe that wazoo regrind is suspect. These are the cams with the proprietary "Simon's STGII" grind right?

Thanks Alan but everything is STOCK, no regrinds, stock lifters, stock everything. The holes are lined up, its just the lifters aren't pumping up. I will have to check the oil pressure properly even though my factory guage reads nice and high, just like before. It could be when the head got welded, maybe they restricted a passage, that happened to someone if I remember correctly!!!

Did you swap any of the lifters and accidentally get the disk upside down? I could see that causing issues.

I put all the lifters in and made sure the discs were there, 3 little valleys facing up, IE lifter bottom.

Are they new lifters or used? I've found you really can't reinstall used lifters since the plastic "washer" that seals (goes around the lifter body) the lifter against the rocker is usually destroyed when they are removed from the rocker. Even if it's a good lifter, without that seal there, the oil drains down the side of the lifter itself, and never puts any pressure into the oil feed hole on the lifter. When this happens, they never pump up and make a racket.

Man oh man, USED,

But bingo, sounds like you nailed it and makes total sense. CRAP.

Good thing that 16v engines are cheaper to make power with... what are lifters like only $1400/set?

[iTurbo]

"Only" $389

Simon, are these the lifters I sold/traded you? I even picked 16 of the nicest ones I had. Suckage!

When I priced them from the dealer a few years back it was $160/ lifter, which came with the rocker arm. So that would be $2650 for a full set

[turbovanman²]

I am going to play with O-rings and see what happens,

Nice JT, but your a little off? and remember, 2.4's are alot cheaper,

Pat I remember discussion about this on the RTML many years ago and I thought the plastic piece was only to aid in assembly at the factory. When I bought new lifters for my old R/T from Mark Grant? back in the day they did not come with new plastic retainers, and worked fine once I installed them. I did soak them in oil for a few days first however.

It does make sense, when I undid the rocker shaft, the lifters damn near fell out, so I could see how not having that plastic ring there could make the oil find the path of least resistance-around the lifter not thru it.

I'll see if I can use an o-ring and post up. Thank god the valve covers come off easy,

I just picture a bunch of torn up O-rings clogging your oil pickup in the pan a week from now. Make sure whatever you devise is up to the task and won't fall apart.

Thanks, I'll make sure,

This is weird, just went for lunch and they were quiet? I wonder if it takes THAT long to quiet down. I've put about 400 km's on it so far.
