Oil from the breather - Honda Prelude Forum

anubyss · 11-30-2002, 01:08 AM

Well went to the dyno today for some minor adjustments and had some serious blow by. The breather spit out a ton of oil. This occurred boosting in fourth. Had to stop the tuning process. I was at 200whp and 185 ft-lbs and climbing then boom. It drives fine and no smoke so I guess the ringlands are ok....for now anyway. I'll just have to drive it carefully until I can get enough money together to build the bottom end.

So, I should be fine as long as I baby the car right (no boosting)? I drove it home just now and no issues. Any insight would be appreciated.

Define what you mean by the breather... The tube left side of the valve cover?

BoYgUaN · 11-30-2002, 01:38 AM

yep ...thats da breather

anubyss · 11-30-2002, 09:03 AM

I mean this.

That tube runs to a catch can. It blew out the line and a lot of oil came out. Could it be something else besides blow by? It seems like a bit too much oil to be blow by to me.

That is blow by. The combustion process gases are getting past your rings and causing the oil to come out the breather. Do a compression test and leak down test to see if/what cylinders are messed up.

I would but now I think I am giong to send out my spare block to GE to be sleeved and finally use the pistons and rods that have been sitting in my closet for about 8 months

. I probably have some issues and just don't want to know about it for now. I can't handle more bad news right now...sigh. Oh well time to fork over some bucks and do a rebuild. I am praying to the Perlude gods to let my car be ok for about two months.

just do the test! better to know than to not know... and if you need the car to run for a couple months, and the ring lands are going, you'd best shut off the boost or they won't make it.

anubyss · 12-01-2002, 02:04 AM

I am not boosting anymore at all. I don't even take it above 3500rpm anymore. I am sending the block out to GE so there's no point in me fixing the blow by now. I am just hoping it holds up for two months. I only drive on the weekends so I think the car will hold up. The compression test will just tell me which cylinder is bad right? I am in save mode now for the rebuild so I don't want to spend money on anything if I don't have to.

Schwett, you are pretty knowledgeable when it comes to turbo issues, would you recommend me doing a compression test anyway?

schwett · 12-01-2002, 03:36 AM

anubyss, i was under the impression you had another block that you were sending out to get built up, while hoping the current one held out.

if this is not the case, i would do the compression test to find out for sure if your lands are really gone. if they're not, you know there's some issue in the crankcase or breather system (though i have no idea what that might be) and if they are, you know whatever you were doing before killed your pistons. either way it doesn't affect the cost of your rebuild or the cost of keeping your car limping along.

so no, the compression test doesn't just show you which cylinder is toast... it shows you if any of them are toast. maybe they're all good and it's something else!

anubyss · 12-01-2002, 11:47 AM

Yes I am sending a spare one out and when that comes back I am swapping it with the block that is on the car. The reason I wasn't going to do the compression test was that everything is going to get pulled and looked at before install. But I see your point of it perhaps not being the rings and something else. I guess I'll have it done. Thanks.

Quaalude · 12-01-2002, 12:00 PM

Do a leak down test. It will give you a better indiction of how your cylinders are sealing and if/where is there a leak. You will need an air compressor and leak down tester to perform this though.

Do not send it to Golden Eagle..Send it to AEBS or get the Darton sleeve kit and have a local machine shop. I will never deal with Golden Eagle again, their customer service SUCKS.

i have to disagree. i thought they were extremely helpful, knowleadgeable, and honest.

SilverLudeSi · 12-01-2002, 02:27 PM

Yeah, they were always helpful with me. Vince answered all my questions and turnaround was not more than a week. They have just been getting exponentially busier these past few months.

ummm yea · 12-03-2002, 11:02 PM

hey i had oil come out my breather too...when i was changing my valve cover i noticed that there was alil bit of oil on the breather...i was jus hoping that i jus spilled sum oil sumtime after the turbo went in...

i guess imma go do a compression test when i have the time..

anubyss · 12-04-2002, 06:29 AM

A little bit of oil is normal.

symba · 12-05-2002, 06:37 AM

Anubyss, you have a line from your breather to a catch can but normally that's attached to the intake pipe right? I'm just trying to make sure I'm looking at the right thing on my h23a

anubyss · 12-05-2002, 07:23 AM

Yes it's going to a catch can. It's the same line that is in this pic coming off the breather.

anubyss, something doesn't look right to me. Your catch can "should be" inbetween the pcv system on the right side of the valve cover where the line goes from the pcv valve to the intake manifold. The breather tube should still be connected to the intake pipe (like stock) for positive pressure into the system, or you could have put a tiny breather filter on it. Can you better describe your catch can setup?...maybe its ok and I'm just not seeing the whole thing. Btw, I have the Moroso can. The Greddy looks nice, but I thought it wasn't baffled inside. Did you correct that?

anubyss · 12-05-2002, 04:33 PM

You are correct, the Greddy catch can is not baffled to my understanding. I just a got a good deal on it so I bought it. I still have to figure out something for the other tube. I just have it hanging right now.
