14b on d16y7, oil leak from valve cover?
 

Hey guys, i just got my 14b installed on my d16y7, gated at 7 PSI, basemap with Crome from Phearable.net, my oil feed and drain lines are on solid, but as soon as i start to take off, oil starts leaking from an unknown location (since it doesn't do it at idle, i can't get a specific location of where its coming). It's coming from up above, which made me think it was my valve cover gasket. There was oil right where the valve cover seals, so it looks like it was coming from under there, but i replaced the gasket and bolts and the valve cover is on tight and it's still leaking. I was thinking headlift as a possibility, but i drove it today and wasn't anywhere near boost, it was reading vaccuum still and it started leaking. Because of this, it's not that i'm hammering on it and losing oil, its just leaking out somewhere. Anyone with any ideas? There is most oil on the right side of my block/valve cover (driver side) all over my belts/resorvoirs and also on my hood where it is shooting up. Ideas?

I used to use 10-30 syntetic oil I had leaks every where, but somebody recomended me 5-50 performance oil, soon as I put this oil never had any problems with leaks sence then. I love 5-50, works the best for turbo cars.

DSL!!

but back on topic havr you tred replacing the gasket?

maybe remove the VC, clean everything and apply new sealant?

Re: 14b on d16y7, oil leak from valve cover?
 

is the dipsick on??? :1
haha just wondering cuz it happened to my nephews turbo ls haha oil everywhere... :8

Re: 14b on d16y7, oil leak from valve cover?
 

valve cover, distributor, cam seal, blowby blowing oil out your dipstick tube, turbo oil line feed, bad turbo drain, valve cover vent all things to check for leaking oil. Spray/clean all old oil off engine with brake cleaner and take her for a short drive and look where its coming from. Look for oil splattered on the bottom of your hood. If it is, the leak is probably from a pressurized source, not just leaking from somewhere like your vc or cam seal

Has anyone told you lately that you are ------- retarded?

Re: 14b on d16y7, oil leak from valve cover?
 

sarcasm

Re: 14b on d16y7, oil leak from valve cover?
 

i just replaced the valve cover gasket with high temp sealant on the 4 spots and the leak is still the same. Seems to be coming on the cam gear side of the engine, right below my valve cover. There is definitely oil on the hood, which leads me to beleive its a pressurized source as well. I can tell its about the turbo or atleast shooting up above it becasue there is oil on the top of my manifold and stuff. Oil drain is solid, oil feed is solid, valve cover is solid, dipstick tube i guess is a possibility (its in there btw haha), its not over by the dizzy, its actually totally clean over there, i guess maybe cam gear seal but idk. My car is going to a shop tmrw to get my downpipe welded and theyre gonna see what they can. Thanks a lot guys

Re: 14b on d16y7, oil leak from valve cover?
 

get some good pictures of where its leaking

Re: 14b on d16y7, oil leak from valve cover?
 

Your probably using PCValve. Is your PCValve conected to intake manifold?

Re: 14b on d16y7, oil leak from valve cover?
 

the PCV valve is connected to the intake mani right? The leak is definitely coming from the front, right above the turbo, and seems to be shooting up. Getting pics in a few minutes

As you can see its on top of the valve cover, on top of the turbo (since oil is pooling in the bolts), and also sprayed up on my hood. Its also on my PS resorvoir/hoses, and my whole manifold is soaked. You can also see that the dizzy is compltely dry, that whole half of my engine is fine. Ideas?

And you guys like my new painted valve cover? 8)

Re: 14b on d16y7, oil leak from valve cover?
 

P.S. those pictures are rotated, they're still processing in PhotoBucket, sorry!

Re: 14b on d16y7, oil leak from valve cover?
 

Holy Christ.. I thought my VC was leaking bad.. I just have a little bit of wetness on the top of my mani.

Where's your dipstick?

edit: Oh, it's way the ---- over to the drivers side. Hmmm.

Re: 14b on d16y7, oil leak from valve cover?
 

You didnt mention if your running a restrictor valve to the turbo? Also what type of Ventilation do you have as far as your pcv setup? Obviously you have a breather on your valve cover, and somewhere in this thread you mentioned you still had the pcv valve connected to a vacuum source. that may be your problem, or your cam seal is just old and needs replacement? Try uplugging the pcv valve, plug up the vacuum hose, and vent all the crankcase pressure into a bottle or the ground and see if that helps out. If so pick up a catch can set up and hook it up, most all turbo cars need them since your forcing air pressure into the engine under boost. Probably why you dont notice it leaking while its just idling. Good luck

Re: 14b on d16y7, oil leak from valve cover?
 

resitrictor valve? like oil restrictor? Yes, i am if thats what you are talking about. And i don't know much about PCV valves, i know i've got my valve cover vented with that filter, and the hose that originally was connected from my valve cover to my old CAI isn't connected anymore, you can see that in this picture:

Attachment 14271

So if i got a catch can where do the hoses hook up? One end to where the filter on the valve cover, but what about the other end?

yeah i've got my manual right here and i'm not new to Hondas, i'm also not ------- stupid, but i don't know exactly where my PCV valve is, anybody got a picture of where one is on a d16y7?

Re: 14b on d16y7, oil leak from valve cover?
 

Pin hole in oil line ???

Re: 14b on d16y7, oil leak from valve cover?
 

idk man, because it doesn't happen at idle, my car is going to the shop right now to get the downpipe welded and i guess they're going to take a look at it. It sucks because i hate having a shop work on my car, but i am at an absolute loss.

Re: 14b on d16y7, oil leak from valve cover?
 

Could be, but at idle isnt the oild pressure in a honda between 50 to 80 pounds (not exactly sure), i know its high up there. Anyway my point is you'd think at that pressure at idle it would leak at all times?

Yes i meant oil line restrictor. Heres a good thread on a homemade catch can set up for around $30
https://www.homemadeturbo.com/forum/...?topic=41175.0
or you can check the sponsor's, i've heard good things about the Z10? catch can kit. Ebay's got them too, one of they very few aftermarket products i'd buy off ebay. That thread will help you understand how the pcv system works with boost and how to vent it properly.
I'm not entirely sure where your pcv valve is on the y7 manifold, it may be on the black ventilation box on the rear side of your block. Good luck

Re: 14b on d16y7, oil leak from valve cover?
 

^ i actually read that earlier today, helped me.

On another forum somebody mentioned possibily bad seals and the turbo is spraying oil itself. What do you guys think about that?

Re: 14b on d16y7, oil leak from valve cover?
 

that doesn't really sound very likely, at least ive never heard of seals that bad to make it actually spray oil averywhere.

from the pics it looks like dipstick might not be all the way in or not sealed or liek said above, it could be a pin hole in the oil feed or messed up fitting where it meets the turbo.

and it wont do it if somebody holds the rpms around like 4k while in nuetral? maybe you can get some paper towels or something and loosly tape them around the oild feed then drive real quick to see if you can see where it might be coming from?

Re: 14b on d16y7, oil leak from valve cover?
 

somebody on another forum mentioned power steering pump's seal at the shaft. I'm pretty sure its not a pin hole, but what do you guys think about that?

Re: 14b on d16y7, oil leak from valve cover?
 

put any p/s fluid in it lately?

Re: 14b on d16y7, oil leak from valve cover?
 

check the PS fluid level and that will tell you if its that. i had a ps fluid leak once but would only get on the driver side frame and around there

Re: 14b on d16y7, oil leak from valve cover?
 

I thought oil pressure at idle was 10psi??

Re: 14b on d16y7, oil leak from valve cover?
 

oil pressure at idle is not 10psi evrything i have seen is ~40 psi. if you are running 10psi at idle you have a problem

Re: 14b on d16y7, oil leak from valve cover?
 

I had the same problem last week. PS fluid on the pulley and on the hood and on the floor...

The hose was not fully inserted in the hole.

Re: 14b on d16y7, oil leak from valve cover?
 

10psi per 1000rpm after the engine is hot is fairly normal. Your light won't even come on unless that ---- drops to under 5psi or so (not sure of the exact #, some guru will chime in and pwn me). Mine's more like 10psi at idle of 800rpm or so on a super hot day.

Re: 14b on d16y7, oil leak from valve cover?
 

but you should know if its PS fluid or oil, they dont even look the same.
telling you man, put one of those blue shop towels over the feed line, at least you will be able to tell where its coming from

Re: 14b on d16y7, oil leak from valve cover?
 

Doesn't ---- like that piss you off. Clean everything up real good man, and then watch the engine while it is idling. With the mess you have there, I'd be willing to bet you'd be able to see whereabouts it is coming from. A friend of mine had this probaly recently with his DSM and I BELIEVE the culprit was his cam seals. That ---- was slingin' oil like a bitch. Might not be your issue but it's worth a look-see.

Re: 14b on d16y7, oil leak from valve cover?
 

yeah for sure makes me mad man, thought it was for sure it was valve cover gasket, took it around the block and the smae ---- :7

sadly its at the shop right now instead of on my friends lift or parked in front of my house where i've been working on it latley. The guys at the shop are pretty legit and they let me go underneath it and look around and let me hang out down there while they work. Kinda sucks that i'm not doing it to myself, but this is like the first time since i've got it installed i haven't done it myself, so i'm not worried about it. It's my DD and i just need it running asap! Anyway i'll have them chekc cam seal, have them rev it a little and see what happens, check the oil feed, power steering pump (my fluid looks normal BTW, idk), and the turbo inlet as well. You guys have been super helpful, i'll let you know whats up. Thanks for sure!

Re: 14b on d16y7, oil leak from valve cover?
 

thought i'd let you guys know that it was.......the oil feed line! You guys who suggested that was right. Needed some more loctite and teflon tape. It's solid now, thanks for your help!

Re: 14b on d16y7, oil leak from valve cover?
 

wow

Re: 14b on d16y7, oil leak from valve cover?
 

?

Re: 14b on d16y7, oil leak from valve cover?
 

my VC leaks everywhere under load. fills my spark plug holes and sprays on my manifold n ----. id day theres way to much pressure in your valve cover, if thats where its comming from, somthing is wrong. blow by, valve, not venting etc

Re: 14b on d16y7, oil leak from valve cover?
 

what is this. this looks to be a big problemhttp://i257.photobucket.com/albums/h...T/DSC00743.jpg

Re: 14b on d16y7, oil leak from valve cover?
 

hats the feed for the water, but the water drain is welded shut (its a used turbo), so idk how i could use the feed anyway, and i asked around and a few people said as long as its oil cooled it should be good. Idk, the leak is totally fixed though.
