unless they are solid lifters they shouldn't make noise, if they are then its possible they have too much clearance you might need a longer pushrod..... you can easily check this if you remove a tappet cover and see if you can turn a pushrod when the valve is closed, or even if its loose...

Which brand of lifters?

[vlad01]

Yeah dud that ages ago it would still work but if it was in place it would just read wrong

Also im hearing a clack from down in the valley i think it may be the anti pump lifters but im not 100 percent sure andone else run them and had them clack away?

not sure about anti lift, but I would think they would as they are meant to bleed down?

stock ones clack all the time.....after few hundred redline shifts lol

i've run anti-pump up lifters in the 202, for all purposes you treat them like a normal hydraulic lifter, they need pre-load when installing, but then the difference is they are supposed to not pump up too far at high revs and keep the valve open.....

before running them i used to have issues where on a big long 2nd or 3rd gear wind out, it would get to high revs and just before gear change the engine would start missing, then after you change gears a second or two and it would come good...

if however you are referring to solid lifters then yes they are much more clattery, but thats normally in the tappet covers not the bottom of the motor.

hmm ok looks like ive got to look into something then they dont do it whilst driving well that i can hear just at idle you can hear a slight knocking/clacking noise coming from down in the valley area i just figured it may have been the lifters as im not familiar with there operation but im pretty confident the push-rods the right length perhaps its to long and bottoming out the lifters?? defiantly things ill need to look into

hey guys just wondering what sort of timing should i have in the tip in bump spark map should it be the same as the regular map or should it be slightly more or less the car has surging issues at 60 kmph and light throttle the tip in spark was in the neg in some places i made it around the same as the normal map and it seemed to help im just not sure if i should dig deeper with it or not??

Maybe contact Camtech and get the info from them for there lifters. Many anti-pump up lifter run very little Pre-load and can be a bit noisier that regular hydraulic lifters.

i got another "3 bar map" today and for some reason it peggs at 14.4psi and 200kpa ish with the 3bar map option selected is it possible theres something wrong with my software i really doubt it i checked the voltage and at atmo its seeing anout 2.2ish volts and at 30psi about 8.4volts ish and i have no idea if thats correct or not??

[vt3.8lt]

Never mind guys i wored it out im such a goof lol
