What is this?

[MBLAQ]

just wondering what this plug is for,
coz mine is very very loose.
how do i replace it? can i still drive the car like this?

PCV valve. If you're worried about it, buy a replacement. I'd recommend opting for one from a 2J Supra.

wow

what type of intake is that?
where did you get that from?
sorri for hi-jack of thread

[vyets]

It's a HKS intake.

Nice J's cover btw :)

pcv = positive crankcase ventilation

as it says it vents blow by from the motor back into the intake then into the combustion chamber to get burnt up (emissions requirement). you can get one from whatever car you want just make sure you inspect it by blowing thru it each service because if it gets carbon build up and gets stuck closed, you can pressurise your sump and start blowing the dipstick out

[MBLAQ]

where would i source one? are they just universal from like supercheap or auto one?

it is dangerous to drive the car with it loose?

[STAiN MASTER]

I think i saw this car for sale did you just buy it?

lol mate there only ment to fit nice and snug in the hole not be super tight
if its that bad you might need a new gromit

[stndrd]

dont bother getting a 2JZ one. it doesnt give you any extra power or flow so just go to honda or bursons/repco (whatever is in your state) and get an OEM replacement pcv and rubber grommet for it =]

Never known a PCV valve to be a real snug fit. Unless it falls out with the weight of the hose or you can hear pressure getting by the grommet, don't worry.
I'd be more worried about the air intake, running the plumbing through the radiator airfolw.
It is a puzzling route for the intake, just my opinion though.
Does it get cold air from outside at all or is it drawing from the engine bay?
