    No lifter noise solution

    Yes, you read right. If you want to eliminate your lifters from making any noise all you need to do is regrind your cams. In other words you're going to add performance and make your engine quieter by regrinding the cams.

    I've done this to my KL engine and now to my DOHC BP engine and the engine runs smooth and quiet. Right now I have a BP DOHC engine in my 323LX. I perform this swap last weekend, it took me 6 hours in total, not bad for a first time.

    Everybody that has purchased regrinded cams from me for their KL, B6 or BP engine says the same things, that their engine is much more quieter than before. The reason is simple. With the existing cams the lifter don't see much pumping action, once you regrind the cam lobes the lifters (HLA) start pumping and leaking as they were meant to do.

      While I feel its cool that you offer your cam grinding services to us Protege guys, I find it appaling that you would spout off bull**** like "there is no fix, buy cams from me" to address this issue.

      There is a fix. The noise is caused by clogged lifters. You could do one of a few things:

      1: Flush your engine a few times with some kerosene until all the build up is out of it

      2: replace your lifters with newer style lifters which have larger oil passages

      3: replace your lifters with solid lifters out of the newer Miata BP's.

      4: not care, since it doesn't affect performance, seeing how our engines won't rev high enough to have a valve-float problem due to one or two "noisy" lifters.

      5: i could think it up but there are other solutions i've read of that work as well.

      I don't see how the hell a grinded cam could eliminate lifter noise, seeing how the problem isn't with the camshafts duration or lift specs. It all has to do with a ****ty hydraulic lifter design on mazda's part, that have clog prone holes, causing them to no pump up properly.

      how this has to do with camshafts is beyond me...please enlighten me.

        maybe an unexpected by product of replacing the cam shafts cleaned out the lifters a bit? who knows? i don't my engine had a wicked valve tapping type sound, to what my mechanic was saying were caused by the lifters. i went to my local 15 minute oil change place and had them run a full oil system flush with a machine from envirolution (i think thats the name). basically pushes mineral oil heated to 150 degrees and pumps it through your oil filter port and recycles it out of the oil plug in the oil pan. it's pressurized to a few psi (maybe up to 8 or 10 psi) throughout the whole flushing process. then they pull a negative vaccumm on the system to pull out all the sludge and remnants. cost 80 bucks, couldn't be happier with the results. doesn't make your car faster by an means, but it'll run smoother and cleaner than it did before
        peace

          Usually thicker oil will help the problem greatly
          instead of a 5w30, or 10w30, try a 15w50, or a 20w50 (especially if you live in a hot climate)

            Where in my thread did I state that there no fix for the lifter? All I stated is that by regrinding the stock cams you're definetly going to eliminate or reduce the lifter noise by a large margin. The problem is not the lifters but the stock base circle on the camshafts is a bit too big hence not much pumping action is hapening with the lifters. By reducing the base circle even 0.010"your lifters will have to get more pumped to make contact with the base circle.

            It has nothing to do with cloged lifter that's a bunch of bull. I know more about these lifters than most of you guys since I experimented to see what's the maximum displacement the lifters can give.

                Wow, well if thats what you think. I guess the holes on the lifters are there for aesthetic purposes?

                  Look at the title of this thread "No lifter noise solution".

                  Stop trying to advertise your cam regrinds by spouting off such crap! Spread of misinformation is a big f**king peeve of mine.

                  Not that I think your cam regrinds aren't good, I've heard they are great. You could try saying how they increase power, broaden the powerband, etc. but don't LIE to people about how they will eliminate lifter noise!

                    Your a funny guy. Look the holes are there for oil pressure to enter and pump the lifter, also the hole is there to deplete(leak) the oil out. The stock base circle doesn't make the lifter have much movement in the up or down direction, this causes the lifters to make noise.

                      Ask around people in ProbeTalk that have my cam grinds on their KL engine (Probe GT, MX6, 626) and they'll all tell you that it reduces lifter noise by allot or eliminates it completly. If you question this than all you need to do is send me your cams + $250US, I'll regrind them then you can install them and you can see/hear for yourself. Why would I lie, I'm not trying to sell my cam grind because they reduce noise, I'm selling them because you get the best performance from any other bolt-on and all those that have them installed have great things to say about them.

                      BTW I'm mikeseli at ProbeTalk.

                        True the holes are there to "pump up" the lifters so the can operate properly.

                        If that hole gets clogged, it causes them to not pump up properly and can cause them to "stick" making a clicking sound when the cam lobes spin over them. Of course this is caused by carbon build up due to non-frequent oil changes, etc.

                        Your original post said "eliminate lifter noise". While I am open minded to the fact that MAYBE your cams can slightly reduce this sound, there is no way they will completely eliminate the lifter noise, since the real problem is in the super tiny holes in the lifters. Why would mazda update this design with larger holes if they thought it wouldn't fix the lifter sound? why didn't they update their camshaft design?

                          Maybe true...like I said in my previous post. I'm not doubting that MAYBE your cams can reduce the noise to the point whree people don't notice it anymore, but it sure won't eliminate/fix the problem.



                          And I was actually considering having my cams regrinded by you on ProbeTalk....so SWEET, your offering me a price of $250 for regrinding my KLZE cams?

                            I am with FESTIVAS RULE on this one.

                            Reground cams will reduce lifter noise PROVIDED they are milder than the stock cams.

                            The lifters tick when they are starved for oil. They starve for oil when they are clogged OR when the ramp rate is too high... ie... when using wild cams.

                              KL cams cost $395 + shipping to regrind since there's 4 camshafts. The price $250 is for the DOHC BP engine.
