How much blow by is normal. Mine is not dripping out of the tube or anything but seems like a little much for 200,000 miles?? Any input??
-
how much smoke comes out when you take off your oil cap?
-
Hard to see in the day but visable in the headlights. Its got the hole in the cap and a tube by a previous owner.
-
if its hard to see, its probably not enough to worry over :)
-
Your may already have one but..
When you take the cap off can you see the cam?
If yes get a new VC gasket and an oil baffle that goes under it.
Will help with the oil vapor.

my 86 golf that had about the same mileage had soo much blowby that when i took the oil cap off it wouldnt sit on the valve cover. it would kinda float like a beach ball on a fan. and when i routed the hose from the valve cover to the intake manifold from the manifold to the air box the air box would fill up. and im sure it dripped oil into the engine.
-
I think some air blowing out is normal, but a lot of smoke isn't. Mine blows a bit of air out and no smoke.
-
There isnt any oil dripping out of the tube but it is a little wet inside. Just a little worried still learning the vw hand book :lol: Thanks guys!!!
-
If your really worried about it you could always do a compression test but it dosent sound bad
-
Might just see how long she'll go what I dont know wont hurt me. Right? :roll:

Check your oil mileage if it is not so good then a ring job might be in your future. If there is blowby your compression will be low leading to hard starting in cooler weather. Cheers Dan

Right. Being as you are in Virginia, you don't have many cold days, so if your rings are shot, you will not have too hard a time starting in the cold. (one trick if you have a really cold day, park on a really steep hill and roll start it - the fast spinning will more than make up for the cold and lower compression)
It will be a mater of diminishing returns - the more worn your rings, the more oil and fuel you will use. At first it will be cheaper to just drive it. As they get worst (years ??) you will get to the point its cheaper to do the ring job (if you have the skills / tools).

Would I be better off to go ahead and find a turbo motor and build it and run this one till kabluie?
-
i personally would lol

I'm very new to the world of VW diesels. I just got mine about 1 month ago. It is a 91' jetta non-turbo diesel w/ 111,000 miles. I have been burning a little oil and noticed some smoke coming out when I take off my oil cap. What exactly does this mean?

If its not a huge constant amount, its normal blow-by. All engines, new and old have some. The question is how much. Be sure to keep your air filter / manifold clearn so you don't have a run-away event.

Checked the oil again today and not loosing any oil.? :?
-
I have a lot of smoke and preasure comming out of the oil vent hose and oil fill cap on my 85 golf with unknowen milage. if I hook up the relief hose going from the valve cover to the intake manifold I loose oil out the dip stick if I unhook it I don't loose oil and I have no blowby comming out the dip stick is this still bad rings or a valve?
-
Would synthetic oil keep the smoking and pressure down when I open my oil fill cap? I know the syn v. dino oil question has been posed many times, but I have heard many different responses.

Sounds like you have just a little more than normal blow-by. I would not worry about it if your oil consumption is tolerable (1 q extra per oil change interval is my idea of acceptable) - so I'd get / made an external oil separator / breather for your valve cover vent.

Same thing.... I would not worry about it if your oil consumption is tolerable. Go synthetic and your mpg will increase and your starting will be easier in cold weather especially. The smoking is normal blow-by so don't worry about it. The pressure, your breather can't be restricted. But, oil type will not have a big affect on this. If your rings are shot, they are shot. Live with it or rebuild. Likely, living with it will be OK as long as it runs well in all other aspects.

you got the car 1 month ago... how long was the car sitting for, b4 the purchase? and b4 that? and b4 that
a leak down test would be a better test then a compression test.
if its been sitting for a couple of years, you could end up with stuck rings..
or worse, a bad ring caused by anti-frezze sitting in the chamber, just becuase a bad head gasket that caused a hole bunch of pitting.
(http://i376.photobucket.com/albums/oo203/jjweird/IMG_7392.jpg)
symptoms were. low coolant level all the time, coolant hose's were hard as rock.
my guy didn't do the ring job yet and i don't think he's got it planned in the future either. sad and cheap.
as for the smoke coming out of the PVC valve/oil cap like a ciemny on fire.. if your worried about it, you can divert it to the ground (just like the big trucks) and plug up the part that connnects to the air intake (N/A). turbos are on the boot near the turbo

Thanks guys for the help!!!!CHEERS!!!!
