f22a1 vacume hose question

[The_New_Guy]

what could be causing this and is it bad? what problems will or could this cause to a car and how can it be fixed?

[SOHC-FTW]

Thats the pcv if its kinked bad enough to cut off breathing it will cause unwanted pressure in the engine/crank case an ya don't want that.The pcv is a vent for the engine to release pressure.Just replace the hose shouldn't be over $3.

[The_New_Guy]

could this mess with the idle when stopped at a stop light? if so then i finally found out why my car is dropping rpms super low at stop lights or when its in gear

[SOHC-FTW]

Possibly yes its vaccum pulled from the intake.Replace the hose(any local parts store should have the size of vaccum hose you need) an go from there.

Lol yeah, it could. But I wonder how dirty the pcv valve and that tube are, those would cause a idle issue if they are packed full of oil and gunk.

[SOHC-FTW]

They usually are an OP might aswell replace the pcv while hes at it.They are also cheap.

What I was getting at was that most likely his IM is caked with oil and other nasty gunk, THAT would totally cause his issues. Op, pull off your intake tube, turn the tb to WOT and shine a light in there and let us know. I bet its nasty in there.

Like i said they usually are.Ive not seen one intake spotless.Oil is pulled in from the vc breather to the intake tube,and from the pcv.So their is gonna be build up no matter what.Especially the more miles/wear on the engine the more blow bye you get.Few guys have made filtered catch cans for their pcv seems to work pretty good.

[dj_ender]

Right, just making sure the op knows to check and clean the IM. I got bored one day and just ripped off my IM to clean, for no reason and it was nasty, 2 cans of brake cleaner later and it was spotless!

I've seen some really bad ones that looked like they could cut power down quite a bit.Cleaning of all ports every now an then isn't a bad idea.

Seafoam is your friend...

[The_New_Guy]

ok so i bought new tube and pvc valve and it idles a lil better but still dropps pretty low when i put it in reverse no so much as if i put it in drive. and seafoam i herd it can mess stuff up in my motor? true or no

[deevergote]

Yes, seafoam can do damage if used improperly.

If your idle is still giving you problems, follow the instructions on how to set your base idle. It's in the thread at the top of this section that says 'read this first' (I'm sure you saw it when you read that thread first, right?)

[The_New_Guy]

yeah i saw it but my idle is around 900 when in park some times a grand but when i put it in gear it seems to drop to about 600

[dj_ender]

As far as I know the only real way to do damage is to leave It soaking too long. I've used it many times in multiple cars, and no issues. Of you plan to use it go to youtube, search seafoam and watch the one by seafoam. Used right it can really help your engine, especially a 20 year old car like ours.
