While changing valve cover gasket....

[Jean]

Did an oil change and replaced the valve cover gasket as it was leaking a bit, and what did I find?



so far so good... oh wait





These hoses are only about 6 months or so old.... no wonder I could never get my idle to stay rock solid as it would sometimes fluctuate about 50-100rpms randomly.



This is the icv to intake manifold hose, I could actually see it collapse while the engine running and noticed a crack in it.

WTFBBQ...I got these from autohausaz, but this time around picked up a set from dealer. We'll see how long they'll last.





So...check your hoses, they might LOOK ok but that's about it.



Picked up a set of new ones, installed and idle is solid now!

hmmmm....something else to look into.

i broke that hose were it comes into the VC when i did mine. now it leaks a bit of oil and i'll fix it later.

I need to check these as my idle has been off a little lately.

I've had iffy luck with some of the hoses I've been getting lately too... I get everything from AutohausAZ but I'm sure they carry what everyone else does.

[mikeedler]

looks like your "new" hose is already about 2 years old too. and seems it was made in the u.s.-- kinda odd to me.

That's a picture of the 6 months old hose actually from autohausaz that failed.

[Huff]

Funny, just did my valves and the same issue is happening to me. Hoses look fine and did the ol' carb cleaner spray trick, but it still seems like a small vacuum leak.

Thanks for the justification to check those out again.
