Solid lifters?

One lifter is making noise so the Chevy person wants you to put solid lifter in to quiet it down?

I hope you don't let him within 10 feet of your car when it comes time to work on it. You bettr find the bad one because if you go with solid rollers your going to have 16 "bad" ones. Since you don't know the differance let me try and explain it. There needs to be some "slop" in the valve train to make up for things like heat expansion so that the valve comes completely closed.. A hydro lifter uses a cushion of oil to make up this gap. therefore there is no actual gap between the valve tip and the rocker arm. A solid lifter dosen't use this oil cushion to expand an to take up the gap. So with soild lifters you actually have a gap between the valve tip and rocker arm. The noise comes from the rocker hitting the tip when the cam lobe starts to ramp up to open the valve. So a solid lifter cam will make more noise than a hydro cam.

If you just put the rockers on be advised that they will make more noise than the stock ones. If you can't come across a lash problem check your rockers for side to side play. Are they bolt down style rockers or stud mount?

I agree with you. Another thing to check is the valve train geometry. Make sure that there is not any push rods contacting the openings they go through. All it has to do is just barely touch, and you have what sounds like lifter noise. I've seen many times in the past, when going with 1.7 rockers, where the openings had to be opened up a tad for push rod clearance. If you have decent clearance for all push rods, then consult your repair manual again, and verify that your adjusting the valves correctly.

That's kinda what I thought. I didn't want to show my bias in the post, but you've confirmed what I thought.

I think he only waxes his paint. Anything more technical than that he leaves to his mechanic.

Stud mount. By side to side play, do you mean a twisting motion on the rocker, or actual side to side play in the roller bearing?

Chris

Yes, that's a good one...

Let's see, I have one hammer that makes too much noise...lets see if I put

16 hammers in it should quiet it down...I guess that's Chebby logic...May I suggest a set of fuzzy dices and widnshield pompoms...That shoud quiet it down, fuzz absorbs noize quite alot...

Hihi...hoho...:-)

2 cents...

I have not checked the openings. I have guide plates, and obviously the pushrods contact those. Is that a problem? By openings, I assume you mean the holes in the head, right? With the hood up, I do hear all the rockers clattering away, but there is one that is much louder than the rest. As I drive down the road, I can hear the "tick tick tick" sound reflecting off buildings or other cars. Is it possible that I have just one bad lifter?

thanks, Chris

Yes, that is what I meant. Also, when you adjusted your valves, did you do it with the motor at operating temperature? If your positive that you have them adjusted correctly, then the next thing to look for is an exhaust leak. It's possible you might have a loose header, or just one tube of the header leaking, or a blown header gasket at one tube.

A slightly loose spark plug can cause the same sound (a problem I used to have in my '67 Continental)

take care, Scott

Solid lifters are a step back into the stone age. Roller lifters are quieter, much more efficient and allow the use of the more advanced cam profiles. Right now roller lifters are "state of the art", anything else is second best.

Solid lifters are great for high rev applications, and the roller lifters seem to be the best of theml. Roller lifters are solids with a roller on the end. You really need to go to a cam designed for solid lifters though.

Hydraulic lifters are a little "soggy" (they rely on hydraulic pressure, and give some sponge in lift), but for most applications they work well, and then you don't have to yank your valve covers off every saturday afternoon to check your valves before you go out on the town. Until you've got some good breathing in your motor, don't even consider it.

Tell the Chevy guys to get a life, I run solids in two motors, but anything that I want to drive more that occasionally, I'll go hydraulic. They can breath my exhaust from my little 5.0 (hydraulics), and if they don't like that, I'll pull out the Lingenfelter (it has solids). They can spend their time checking valves, but I've gotta get the kids loaded up to go to Porky's on Saturdays.

No not a twisting motion. Your guide plates should keep that from happening. It would be the mounting shaft to bearings. The snap rings may be allowing a little more motion.

To be honest after reading your description of hearing it off buildings as you drive by, my bet is an exhaust leak over a valve noise.

MadDAWG

Liked that did ya? :) The Chevy guy's fix was way to funny for a simple ROFL or LOL

MadDAWG

Yes, it is quite loud! :) But I'm pretty sure it's not exhaust. It is not at all throttle dependant. Blipping the throttle actually drowns it out with tailpipe noise. The clicking is most noticable when coasting with no throttle at all. I've had the headers and the H-pipe on and off a few times since I installed the heads, and the valvetrain noise is unchanged. I did have a noticable exhaust leak just the other day when I put the H-pipe back on. I retorqued the header to H-pipe nuts, and it's fixed. But the valve clicking is still there!

I have also checked the spark plugs. I noticed that the cylinder nearest the driver's side firewall (what number?) was slightly darker than all the rest. Is it possible that one of the lifters for that cylinder is collapsed, giving less valve lift (either intake or exhaust), which results in a richer mixture in that cylinder? That's my latest theory. Could a brand new Ford hydraulic roller lifter be defective?
