GT Phayer Posted April 28, 2012 Share Posted April 28, 2012 hi can someone give me some advise for checking my shim adjustments correctly as i have an annoying tapping noise from the cylinder head area thanks. Also just to add the car gear is tensioned thanks. Quote Link to post Share on other sites
shorty Posted April 28, 2012 Share Posted April 28, 2012 With cam lobe up slide feeler guage under and measure the gap between the bottom of the lobe and top of the shim. off the top of my head i dont remeber the limits. im sure its in the tech section sumwhere.

Ryan-11 Posted April 28, 2012 Share Posted April 28, 2012 If you need to adjust the gap you will need to measure your shim and measure the gap size and workout what size shim u need to get from toyota Quote Link to post Share on other sites
GT Phayer Posted April 28, 2012 Author Share Posted April 28, 2012 thanks and i do this with the engine cold right ? how much are shims ? Quote Link to post Share on other sites
shorty Posted April 28, 2012 Share Posted April 28, 2012 Yea engine cold. tbh is easier to just work out what size yo need and as long as its a bigger gap than what you have just nip to engineers and get em to skim the shim. Quote Link to post Share on other sites

GT Phayer Posted May 7, 2012 Author Share Posted May 7, 2012 i measured the shims today and this is what i gotINLET1= 0.10mm2= 0.15mm3= 0.35mm4= 0.10mm5= 0.15mm6= 0.25mm7= 0.15mm8= 0.10mmEXHAUST1= 0.35mm2= 0.35mm3= 0.30mm4= 0.40mm5= 0.40mm6= 0.35mm7= 0.40mm8= 0.30mmis there anything there that would cause the tapping sound ? cheers.

ryan lang Posted May 7, 2012 Share Posted May 7, 2012 the 0.35-40mm may do it fellanot sure of the tolerances though.another thing it could be, it on the inlet cam gear, theres a split in it, with the gear end of the cam facing you, twist the thinner outer section of the gear anti clockwise as much as it will go. i had this on mine when we put 5efhe cams in. did this and it went Quote Link to post Share on other sites
GT Phayer Posted May 7, 2012 Author Share Posted May 7, 2012 cheers for your help mate i tensioned the inlet cam first and still have the rattle lol so i turned to checking the shim gaps il try and find the tolerances thanks again Quote Link to post Share on other sites
ryan lang Posted May 7, 2012 Share Posted May 7, 2012 no worries, i did have them written somewhere, but not a clue where they've got too :/EDIT: found the document, its got all the tolerances etc, except that one :/ lol. if you can wait until wednesday i can check it for you on auto data at college?

GT Phayer Posted May 7, 2012 Author Share Posted May 7, 2012 ive got auto data at work my so il find out when im there cheers anyways. Quote Link to post Share on other sites
shorty Posted May 7, 2012 Share Posted May 7, 2012 Think inlet is 15-25mm and exhuast is 30-40mm or some think like that so one or two are out. thats probs where you issue is bud. overall not badd but a few there that are gonna mess with valve clearence. get em swapped out as even if the tapping dont go the performance will improve ;) Quote Link to post Share on other sites
shorty Posted May 7, 2012 Share Posted May 7, 2012 Just to reinforce though. there is a definate jump on oem tollerence between inlet and exhuast. so whatever you do dont make em all the same lol. Quote Link to post Share on other sites
GT Phayer Posted May 7, 2012 Author Share Posted May 7, 2012 lol i wont mate its not a loud tapping just gets anoying also with the forged engine your ment to get a bit of noise when cold then goes when hot right ? Quote Link to post Share on other sites
Ryan-11 Posted May 7, 2012 Share Posted May 7, 2012 the clearances are ment to be Intake 0.17mm - 0.23mm Exhaust 0.27mm - 0.33mm so looks like most of them are out, thats prob whats causing your tapping sound Quote Link to post Share on other sites
shorty Posted May 8, 2012 Share Posted May 8, 2012 Where did you get them from bud as thats not right from what i remeber tbh. are you looking at the 4ef-te not 4efe?? Quote Link to post Share on other sites
shorty Posted May 8, 2012 Share Posted May 8, 2012 Intake 15-25mm exhuast 31-41mm this is taken from chris over on tgtt he made the 4efte engine assembley videos and has been building forged engines in greece for longer than most have known about starlets. these are the tollerences my engine is shimmed to as are many many others.

Jamie1st Posted May 8, 2012 Share Posted May 8, 2012 If I can remember right, we built my engine to the tolerances that Ryan has posted Quote Link to post Share on other sites
Ryan-11 Posted May 8, 2012 Share Posted May 8, 2012 I believe the USDM 5efe use the clearances that shorty posted and the JDM 4efte uses the clearances i posted up Quote Link to post Share on other sites
shorty Posted May 8, 2012 Share Posted May 8, 2012 Hmmmmmm. fist i appolagise. as im not afraid to admit when im in the wrong. i would guess that running the 5efe specs is going to cuase premature closing of the valves and take away power from all over the rev range. Im gonna pm chris and get some input for this thread. as im now curious as to why he builds to 5efe shim tollerence. id also like to know wich will give the best results.

Ryan-11 Posted May 8, 2012 Share Posted May 8, 2012 i only found that out when i was searching tgtt for valve clearances when i was building my engine, i thought all 5e and 4e clearances were the same, maybe worth giving Texx on tgtt a pm too, thats where i got all the info from.

shorty Posted May 8, 2012 Share Posted May 8, 2012 (edited) Ok cool ill pm him too bud as i think we need a clear answer as to what the effects are from the two different clearences. as the jdm would be the sensible bet but i want to know now if theres a reason some are using 5efe and if they are just mistaken or know something we dont.Edit: both texx and 350ep70r have been pm'd to get more input as to why/what the ill efects could be or if theres a benifit at all. ill post up as soon as i get a reply guys ;) Edited May 8, 2012 by shorty Quote Link to post Share on other sites
