what did they refer to pieces of aluminum on both ends?

 

might as well get solid lifters if you want quiet&better performance

 

Solid lifters are noisier than hydraulics.

 

So you dont damage the lifters while compressing them.

I ended up taking them to Alex at DogboxRacing who works on DSMs/EVOs and I asked him about them and he said he had bled them before a hundred times, so I let him do them, so Im sure they are OK. I did not want to mess with doing that and risk messing something up only to have to take them out again. F that!~

 

so do you have a ticking noise in your engine that you decided to buy this jamm lifters?

 

Comeon man, of course! The tapping wasnt THAT bad, but it annoyed me. I had the cams out to do timing belt and such, so I said, this would be good time to do the non tick lifters.

 

If they are that cheap they are not OEM meaning their is a good chance they are top line units. Makes sense because top lines retail at 130 so JAM is adding their markup so 160 it is. They come with machining oil all over them. I forgot if I bled them or not but I remember a huge racket when I first fired it with them. Then they filled with oil in 10 mins and all was fine. They have been in my car for about 4 years now (the top line ones).

 

Ive got the JAM lifters and have had good luck with them

 

did you bleed the lifters when you installed them?

 

i don't know about that, from my experience the solid ones are completly quiet. For example on my friends 05 spec v you cannot hear them at all the gap is only .007in not much slack. If the solid lifters are making noise they're out of adjustment for sure, there's too much clearance between cam centerline and lifter itself

 

yeah but why buy solid lifters which need to be calibrated every other mile??
its better the hydraulic ones you dont need to be calibrating nothing

 

Maybe, but that's not my experience, FWIW. One reason why hydraulics exist in the first place is because they are (or should be) quiet.

And about the noise, conversely, if there is no noise with solids, the clearances may be too tight. One doesn't know these things until/unless he checks them HOT. If any are too tight (especially the exhaust valves), that tends to wipe out cam lobes quickly.

I'm not saying this is the case, but it's something of which one should be aware if he contemplates using solid tappets.

 

bump

 

so this is a good option to stop the ticking
