4k Valve Clearences

[DearmanKE]

hey everyone, ive got a manual here for a ke70, but it is a USA manual, the stuff in it is still for a 4kc but someone asked me what the valve clearences were for a 4k and i told them the hot clearences as it said in the book, which were

 

intake: 0.2mm

exhaust 0.3mm

 

then someone else told them it was 0.25 exhaust

 

anyway does someone have a more reliable source for what the clearences actually should be

 

hot and cold,

 

cold is needed for ke30myles as he hasnt got his motor to start and needs to redo the clearences.

 

cheers

Hot clearances are 8 thou inlet, and 12 thou ex.

 

Don't know cold sorry, but just do it to these, warm her up and re-check them. Shouldn't be too far out, and it will run. :y:

i can't warm er up as it dnt start to

[DearmanKE]

he means set the cold clearences to that which is 0.2mm and 0.3mm

and it should start, if its not starting it wont be to do with clearences, then once you sort out starting troubles, reset the clearences when its warm

 

good to know my book isnt wrong

if its cold id set the clearances to .25 and .35 once the engine is at operating temperature let run for another 10 minutesa and rip off the rocker cover and adjust as quickly as possibile as to get a correct reading.

 

If there is this clearance when the engine is cold atleast you know the valves will be shut. what have you checked so far myles ?

 

Oh at TDC top dead centre with inlet closing on number 1 cylinder i think the rotor button should be pointing towards no 2 spark plug visually.

 

I had 2 manuals a factory K manual and a ke20/30 manual come in ver handy easy to read.

 

pick the 1200 corolla manual up easy for 30 bucks even at old book shops or swap meets. or order a new one from any car parts stores.

Sorry to dig up an old thread but i was wondering if you always have to redo clearances after changing the head gasket. I just did mine and havent rechecked them and now the car isnt starting. could that be the problem or should i look elsewhere?

To answer my own question, yes you need to redo the clearances, did that this afternoon and its up and running again
