mr_K Posted August 23, 2015 Share Posted August 23, 2015 I have made a table to show which shims need changing and with what size.I uploaded a picture can anyone tell me if the ones ive noted down are correct and out of spec too.Also should i round the required shim sizes to the nearest digit.?Thanks Quote Link to post Share on other sites
GP82 Posted August 24, 2015 Share Posted August 24, 2015 Is this for 4EFTE?! Jus' looked through notes and i shimmed to: Exhaust valves: .012 - .016 inches or .31 - .41 mm Intake valves: .006 - .010 inches or .15 - .25 mm ---------------------------------------------------------------------- T = thickness of removed shim A = measured valve clearence N = thickness of new shim Intake) N = T + ( A - .20mm) Exhaust) N = T + (A - .30mm) The shim sizes are available in seventeen increments of .002 inch or .05mm Quote Link to post Share on other sites

GlanzaJ Posted August 27, 2015 Share Posted August 27, 2015 Did it with mine too , tappets fell out when moving the head and had to put them back in different order , just had them all adjusted at a specialist for £80 Quote Link to post Share on other sites
maddox710 Posted August 28, 2015 Share Posted August 28, 2015 I've got a full set of both shims for sale if that helps Quote Link to post Share on other sites
Flaminsam Posted August 28, 2015 Share Posted August 28, 2015 That looks about right. Seems the sizes are quite large? Could your cams be worn ever so slightly? Quote Link to post Share on other sites
mr_K Posted September 3, 2015 Author Share Posted September 3, 2015 I've got a full set of both shims for sale if that helpsI got almost 32 buckets and close to 40 shims its just that i dont have time replacing them to find the right ones, so far ive taken off my cams like 3-4 times im fed up.Thanks Quote Link to post Share on other sites
mr_K Posted September 3, 2015 Author Share Posted September 3, 2015 That looks about right. Seems the sizes are quite large? Could your cams be worn ever so slightly?I think the gap is too loose,My cams have a few chips on the edges i dont know if they are very worn,Im away atm when i get back ill try get a few piks of the fitted cams and the 2sets of spares i got at home.

5e colin Posted September 3, 2015 Share Posted September 3, 2015 you measured them al wrong kid !!!! your missing the " thousands " digit on your measurements chims go in the thousands not thents thats where your problem is !!!! you also need a propper measuring tool not a varnier there only good for measuring pads ha ha , there is a very good chim chart in the link im pasting have a look in there http://homepage.ntlworld.com/richard.cargill/Weblink/15L_4_CY.pdf Quote Link to post Share on other sites

5e colin Posted September 3, 2015 Share Posted September 3, 2015 the feelers yes there grand the micrometer i dont think so it reads 0.00 there used in engineers shops for basic measurements , my 1 reads o.000 ( micron ) and is used for the automotive industry where its measured in thousands you need something like this to get tru readings ( scroll down and read the info ) http://www.ebay.ie/itm/RDGTOOLS-0-25MM-0-1-DIGITAL-MICROMETER-METRIC-IMPERIAL-MEASURING-TOOLS-/371107866893?hash=item5667c0a90d Quote Link to post Share on other sites

5e colin Posted September 4, 2015 Share Posted September 4, 2015 see if you can get the bigger 1 so you can measure cranks to in the future with a good kit you will get a calibrating rod to !!!!! Quote Link to post Share on other sites
Johnboy GT Posted September 4, 2015 Share Posted September 4, 2015 This has happened to me also. Checked the clearances, swapped with a known good head and cams and it's still there. Is it possible the tension of the cam can cause it? John Quote Link to post Share on other sites
mr_K Posted September 4, 2015 Author Share Posted September 4, 2015 Only if 4e heads used a similar design to the b-series hondas we would of had a very easy time adjusting clearances..Unfortunately Quote Link to post Share on other sites
