Ok any ideas on how to stop the oil from coming out the breather I have on top of the valve cover... I had it hooked up to the carb but when a bolt striped and I took everything apart the whole intake was covered in oil on the inside ... Don’t want the blow by all over the engine and fire wall, any ideas?

Not from personal experience, but I've heard that there are some designes where the breather tube can go to a catch-can that somehow feeds back into the block, or can be checked on a regular basis and emptied.

Here's some interesting reading if you have time to kill...

Where you had it hooked on the carb was not pulling a vacuum on the line was it. That would cause it to suck oil out of the engine. Mine runs from the valve cover to the air filter and i don't get any oil. When i was driving it reguarly i ran it 4 & 5 thousand rpm's with no blow by. Does the engine need rings?

If you get time please come and paint my engine. That thang is purty!

Check to see if your valve cover has a baffle in it . The baffle is to keep oil from going into the intake but let the engine breath at the same time.

I get the same friggin problem. Evaporated oil form the pecker thing form the valve cover. I thought about getting one of those filter element things and shoving it on there like u did.

yes it was hooked to a vac line on the intake below the weber... doesnt need rings new rebuild.

yes it is there it will leak by to oil cap (chrome one) if I put the original one in it then blows out the filter in the back and on the fire wall, would anything cause to much pressure? Or is it just because all lines and stuff from stock are gone... so far I like the remote tank

Blow by past the rings would.

wouldnt it smoke if that where the case?

Not necessarily. The oil rings wipe the oil from the cylinder walls as the piston goes down. The compression rings seal the combustion in upper combustion chamber. The oil rings could be doing there job, the compression rings might not. I hope that is not the case but it could be.

i am not sure ... was thinking it was because i have no smog stuff and no way to breath but the chrome filter in the back? i may try the remote tank... it does get up and scoot compered to stock luvs and will beat most rice rockets off the line here in town so hopefully the compresion rings are good... i do have a block here thats bored 60 over and i have my hot cam in the luv now maybe ill do the 60 over block this summer and see how that improves the truck

I took off my smog and I don.t have oil getting into intake.

Maybe try a pcv valve in that line going to the carb with a vented cap in the valve cover and see what happens. Any oil going in the intake will be burned and do no harm as long as it doesn't foul the plugs. The only drawback there is that on hard acceleration you are going to loose vacuum and may still get blow by.

ok thanks

Simplisticly you are creating more crankcase pressure than you are evacuating.

So either reduce sources of pressure meaning
Rings and/or valve guides have you done things to increase compression? this might be a contributor also.

or increase the vacuum on the oil pan vent and valve cover vent.

this is the only thing I can think of to reverse the airflow at the breather hole from blowing oil vapor to sucking in clean air.

On your intake manifold do you have a vacuum port that you can hook up the oil pan and valve cover vent? I know on the stock luv engine the valve cover vent is attached to a very small hole Vacuum line compared to the one next to it. the oil pan vent is combined with the fuel tank vapor line and then fed into the air cleaner. I would think you need to try to somewhat duplicate the stock setup to adequately ventilate the crank case.

Or a vacuum powered catch can would be cool if you don't want to suck the vapor into you engine.

sorry If I am stating the obvious because you probably know more about engines than I do judging from that dual carb set up.

BTW have you done a write up on your dual carbs or your engine build up? I did a search but could not find it you have so many posts. You are a great contributor to this forum. Next time you come through olympia let me know and we can get some of the other LUV owners together.
thanks,
Dan

Here is what I have on the side drafts

And yes it has been rebuilt so new rings valve guides, valves, pistons and a hot cam. So my thinking is like you its getting to much pressure and I need to vent some of it but don’t know how... I do like the catch can though. and as for knowing more about motors I don’t think so ...motors are new for me and am learning, don’t have the duel on now I need to get the jetting right and it is best to do that when its summer time or at least 70+ deg. so this summer they will go back on.

so an oil catch like this would work ?

that looks groovy for a catch can might just get one myself . i got a smog pump for 81 1.8 if any one needs it free you pay shiping

Sounds like something is clogged up somewhere. I sure hope you aren't facing a rebuild. If you are, well I'll help you if I can. I thought you said you did the rebuild two years ago. It could fail any time you know, and this could be oil coming from a valve stem seal or rings. I hope it's not, but of course I hope you get it fixed.

You have another block too right? The thing about having the beautiful parts is you will still have those, even if you have to rebuild. Keep it posted!

The only thing more beautiful than a sunset is a sunrise.

i think that catch can you posted up is a little "ricey" if you know what a i mean.

anyways, check out the catch can on this engine. alot of turbo guys run catch cans from the blowby that just happens in a boosted application.



you could probably find a way to make it so it self drains, so that there will be not checking and emptying of a catch can.

and yes, thats a hardcore turbo'd G200
