gorganl2000 Posted June 26, 2017 Share Posted June 26, 2017 (edited) just finished a fresh 5e buid after having my car engineless for abour 4 years and sods law theres a problem :| basically i was looking for a few other opinions on what it could be i suspect valve noise but cant pinpoint this... ive measured the clearances and although there not perfect surly they shouldn't cause this kinda noise?? 0.15mm is inlet shim clearance spec (+.0.03mm) and biggest to smallest is 0.22 and 0.250.25 is exhuast spec and biggest to smallest is 0.22 -0.29so i deffo need a reshim (something i neglected to concider when i lapped the valves)(need to confrim specs as 5e manual says 0.2 in and 0.3 ex? or am i missing somthing? in a nutshell:forged 5e pauter rods, weisco -10cc pistons0.5mm headgaskethead and block skimed/decked 0.2mm and 0.4mmlapped vales, new stem seals compression ratio should be close to 9:1i have 195psi bang on compression on all 4 cylnders when hot note, the 5e came out of a running paseo i owned so i know it was perfect before all the work EDIT:after a quick (test) by putting petrolium jelly under each bucket to see how it affected the noise... read further down for more info hey goldenvtr...i just realised somethingthe 5e manual says VALVE CLEARANCE SPECIFICATIONS TABLE (1)Application In. (mm)Exhaust Valve .............. .012-.016 (.31-.41) Intake Valve ............... .006-.010 (.15-.25)(1) - Adjust valve clearance with engine cold. wouldn't that mean your exhaust side are way out of spec---under the minimum 0.31mm? while your intake side is bordering on the high side of the range given maybe someone else can confirm the tolerances https://www.slideshare.net/pacovico/motor-5epg 2 YET according to ttgt.com the 4efte manual says Intake 0.17mm - 0.23mmExhaust 0.27mm - 0.33mm http://www.toyotagtturbo.com/forums/showthread.php?99425-4efte-engine-timing-and-tork scroll about 3/4 down the page does anyone have a TOYOTA 4efte manual or access to one that they can confirm the valve clearances? i always read that the 4efte and 5efhe have the same head, so why would the two sources above have different clearances?? either which way you look at it, some of the shims are out of spec on your engine goldenvtr, as you noted above,,,,but which is the right spec to follow?!?! http://www.toyotagtturbo.com/forums/showthread.php?85533-valve-clearancesseems that sort of clears it up Edited June 26, 2017 by gorganl2000 Quote Link to post Share on other sites

Turbo Goose Posted June 27, 2017 Share Posted June 27, 2017 Anyone solve this?Im changing my cams tonight see if I can sort the ticking out before japfest this weekend Quote Link to post Share on other sites
GP82 Posted June 27, 2017 Share Posted June 27, 2017 Hey jus' to confirm the valve clearence is: Intake 0.20 +/- 0.03mm Exhaust 0.30 +/- 0.03mm This is going by the 4EFTE manual. So when shimming a 5E turbo motor, you use the 4EFTE clearence as more heat from turbo motor.You want to be on the higher/ looser side, more so on the exhaust. Quote Link to post Share on other sites
5e colin Posted June 27, 2017 Share Posted June 27, 2017 O.20 intake and o.36 on the exhaust it says on mine Quote Link to post Share on other sites

gorganl2000 Posted June 27, 2017 Share Posted June 27, 2017 (edited) O.20 intake and o.36 on the exhaust it says on mine thanks collin---that seem to be smack in the middle of the 5e manual specs what engine was originally in your car?---just to make sure Edited June 27, 2017 by gorganl2000 Quote Link to post Share on other sites

GP82 Posted June 28, 2017 Share Posted June 28, 2017 but isn't the 5e specs a little looser on the exhaust vs the 4efte specs??? the 5e manual says VALVE CLEARANCE SPECIFICATIONS TABLE (1) Application In. (mm) Exhaust Valve .............. .012-.016 (.31-.41) I checked the 5E manual, yes, the exhaust side valve clearance for the 5E is bigger/ looser then what's specified for the 4E. In the 5E manual the valve clearance states: Exhaust 0.31 - 0.41mm Intake 0.15 - 0.25mm I assumed the 5E clearance's would be smaller/ tighter because na motor, but then the 5E camshaft profile lobe is also different compared to 4E? Well I've always specced to the 4EFTE manual (if not slightly looser, for a higher output motor) and also the same for a 5E turbo motor with full 4EFTE cylinder head and after cold start, cylinder head noise is hardly noticeable and from inside the car, non existent on tick over. I guess you got to take into account which camshaft is also being used. Quote Link to post Share on other sites
5e colin Posted June 28, 2017 Share Posted June 28, 2017 Only 5efe 5efhe is different there not all the same Quote Link to post Share on other sites
gorganl2000 Posted June 28, 2017 Share Posted June 28, 2017 O.20 intake and o.36 on the exhaust it says on mine i checked my glanza this morning, it states exactly the same on my bonnet as you have 5e colin Quote Link to post Share on other sites
5e colin Posted June 28, 2017 Share Posted June 28, 2017 al 4efte should be the same ep82 mk2 and 3 and al glanza v tho i do believe the glower ( mk1 gtt ) was a small bit different in valve spec some1 with a glower please check as i cant check on my 1 Quote Link to post Share on other sites

goldenvtr Posted June 29, 2017 Author Share Posted June 29, 2017 (edited) forgot to update this, its all sorted now, reshimed again at 100miles and now done over 1200miles, it still has a minor but random tick on idle but sounds great now oh and when i reshimed at 100miles i also soaked the cames in brake clean then high pressure air though the oilways to mack sure there was no blockages, then retensioned the inlet cam i will take a video and post up next time im under the bonnet. ps,i aimed for intake 0.20 and 0.3 exhaust, my limit was +/- 0.02 Edited June 29, 2017 by goldenvtr Quote Link to post Share on other sites
gorganl2000 Posted June 30, 2017 Share Posted June 30, 2017 (edited) glad you got it sorted goldenvtr can you post up a vid of how it sounds now? do your forge pistons keep noise/slap on first start?.........does the noise/slap go away completely when to operating temperature or just lessen down? asking as it seem some people say forged engines are kind of noisy Edited June 30, 2017 by gorganl2000 Quote Link to post Share on other sites
5e colin Posted June 30, 2017 Share Posted June 30, 2017 Happy days ,just realised something in your comment do you have the feeler gauge o.o1 to o.o5 ???? Mine only start at o.05 and builds in 5s upwards so its always somewhere just not 100% precise Quote Link to post Share on other sites

Mine only start at o.05 and builds in 5s upwards so its always somewhere just not 100% precise mine started fom 0.02 and went up from there, i have few sets now, a halfords professional one and i bought a couple of cheap Chinese ones from ebay, only a few quid each, they do get damaged easily being as i was using the thinest ones so worth buying a couple sets http://www.ebay.co.uk/itm/METRIC-17-Blade-FEELER-GAUGE-0-02mm-1mm-Guage-Measure-/322358204985?epid=630641356&hash=item4b0e0bda39:g:2IwAAOSwd0BVyHcM Edited July 1, 2017 by goldenvtr Quote Link to post Share on other sites

5e colin Posted July 1, 2017 Share Posted July 1, 2017 (edited) no engine in the world likes short journeys worst thin ever for engines thats how they wear faster !!! Edited July 1, 2017 by 5e colin Quote Link to post Share on other sites
