Hyundai VC leaking...

[SleepinGVR4]

Anyone else have problems with their Hyundai VC leaking? It leaks bad. I even got a gasket for the Hyundai VC, didn't help.

its still leaking... looks like its time to go back to Mitsubishi vc

I know right. Sucks because thats the 2nd one Curtis did for me. And he milled the logo into the custom spark plug cover.

Where is it leaking? Is your CAS o ring fresh?

Are you using the rubber washers and nuts from hyundai?

Where is it leaking?

u can still use the park plug cover, just have to tweak it alittle

he is using the hyundai bolts and it was leaking badly out the front above exhaust manifold. tried a mitsubishi gasket and hyundai gasket and rtv'd it pretty good and still leaking

Is there gunk or residue in the (gasket) channels and/or perhaps is warped pretty badly?

I was having a nasty leak on mine ( Mitsu cover, replaced the gasket twice ) that turned out to be a bad/stuck PCV valve.
I bought a Fram model when I first got the car and forgot about it. Every time I went into boost I pressurized the head and crankcase..... /ubbthreads/images/graemlins/blush.gif
Needless to say I have an OEM one installed now, no more re-appearance of the leaks.

I had the same problem with the hyundai cover i got too. Used the hyundai nuts and gasket and it gushed out the top, by the intake manifold.. Oil was everywhere. I checked everything and i still didnt understand why.. So the old VC went back on, and NO leaks what so ever.. Dont know why it leaked though..

Replace the PCV valve first before condeming the valve cover.it is a common problem.

The pcv isn't that old, I'll try that though. Its leaking from everywhere, front back, sides. The gasket is new, the hardware is for the vc. There is nothing in the groove. Idk, we'll see.

What exactly is different between the Hyundai and Mitsu VC's, anyway? Could that have anything to do with it? (Hyundai vc onto Mitsu head)

 

The Hyundai units were never designed to see boost, so if you didn't replace the PCV valve in the VC before you swapped it on you could push the tired unit over the edge and start leaking pressurized manifold air into the VC.

mine works fine, used new washers and gromets from hyundai, and a new gasket

Or just take out the crappy valve and run a catch can without dumping sludgy oil air into the intake. Just my thoughts but I really don't like the whole PCV system.

 

[BoostedAWD91]

he has a catch can

I'm using the Hyundai valve cover with a Fel-Pro gasket meant for it. I'm not getting any leaks. Are you still using the stud/nut combo? Mine used to leak a bit, so I went with SS allen heads and Neoprene backed washers tightened down pretty good. No more leaks. I have the right length bolts at JNZ, I ordered extra's. You could try that if the PCV doesn't fix it (I'm running a barb fitting, no PCV).

I've always used gaskets and studs from an Elantra gls, with the 1.8. I think 94-95 was the year? Anyways mine doesn't leak, I can get the part numbers if you need them.

I used bolts with my Hyundai cover from a 1997 Sonata.8 long bolts 6 short.Part# Hyundai 22448-33131 short [email protected] long bolt@8 both comes with washers.They are $2.44 each
