b18 help

[KERNOWCIVIC]

hi people

my b18 is burning oil when in the v-tec? only in v-tec and stops when you ease off the thottle.

it has got a de-cat on which i had to do when i put a new cat back exhaust on it.

could the de-cat be the problem?

thanks everyone

The b18 do burn oil , but there could be a few options , What oil are you running you need to be using 10w 40 Castrol Magnatec. As thats what honda use . after that valve seam oil seals and after that piston ring or ovel cylinders , How many miles has the engine done . Rich.

If it's big plumes behind you when you VTEC it, it's probably oil seals! If it's loosing oil without visible smoke... Change the oil

its not masses of smoke its just enough to notice. and it depends on how hot the engine is if i go on a half decend run it does not seem do it.

i am running her on castrol gtx 10w40.

she never used oil until i did the de cat. the only reason i did it was the cat collapsed and the car wouldnt rev above 4500rpm so spoke to my local dealer and they told me it was the cat,

she has got 118000 on the clock which i didnt think was very high to have probs with oil seals etc.

thanks every one

My DC2 blew the O rings at 68k! but then, that was after 67.5k of insane driving

might just be gas that's not getting killed by the titanium in the cat!

How much oil you having to put in it?

[KERNOWCIVIC]

now thats abit harsh.

not alot half a lilter every 3 or 4 weeks but thats if i drive it like a knob every day. if i drive i it like a girl then i dont put oil in it for months.

do you know how much it would cost to have the oil stem seals done?

thanks

that isnt too bad to be honest mate for a car of that age and mileage. all cars use oil!
