after adjusting tappets car drinking fuel

**90xsi** · 19-05-2007 01:07 AM

hey..
i have a b16a and use to get about 380-400kms out of a tank with a lil vtec. After adjusting my tappets, servicing, and all changing all belts except timing belt i seem to only be able to squeeze about 300kms out of a tank,thats no vtecing aswell.
if i adjusted the tappets wrong will this cause the car to consume more petrol? can someone guide me in the right direction pls cause the fuel consumption is really killing me.
thanks in advance
Regards

possible you adjusted the tappets wrongly? Did you follow the exact factory specs? leave something loose/unattached whilst reinstalling the rocker cover? need more info

What clearance did you set it to?

are you sure its not a fuel gauge problem lol...how low are you running your tank down to ? i get 550km out of my b16a (thats driving it till it starts to cut out lol) and my engine has about 250,000kms and ticks like crazy :P

lol freek, dude i run my tank till im on like flat E and only get 350 if im lucky, i use to be able to get 400kms out of a tank. ive looked at everythin but car just seems to drink fuel like a bitch
my engine is quite old and ticks like a mofo aswell..
thats why i adjusted my tappets in hope of ticking going away..but now my fuel is terrible..
i adjusted the tappets to 0.006inch on inlet and 0.007 inch on exhaust.
so will adjusting the tappets wrong create an increase in fuel consumption?

yeh very bad problem you have there..
you should be getting average 280-300 when the needle is exactly on halfway..

checked your 02 sensors?

i think the problem is on something else - not the tappets too

But did you adjust the tappets when the engine was COLD ?
Have you ever adjusted the tappets before ? Made sure the rocker arm was secure ?
Tried a ECU test to see if a sensor somewhere is faulty ?

ALSO - are your TYRES low on air pressure ? This can be a common thing for more consumption...
