My 95 golf 1.9 TD 200 000km has suddenly started consuming excesive oil, 4-5 liters over 1200 km. I traced the oil to the crank case vent, oil is getting blasted up that tube and into the intake. This sounds like excessive blow-by in my cylinders to me. Is there anything else that could cause this problem?
Is their a good source for pistons and rings to fit the motor after it gets bored to its first over size?

Blue Smoke ?
My 1.9TD 94 from a Golf have 237 000 km on it and it does'nt consume any oil. What king of oil do you use ?
Really weird.
Yes blue smoke on start up. But it smoked a bit on start up even before the oil consumption. The exhaust smells strongly on oil also
I just swiched to UFA polar power 0-40 full syn. Befor that I'd been useing shell Rotella 0-40 full syn for the past 30 000 km.
Could the oil switch have caused this problem?

Before you go and tear apart the engine to fit new rings and such, you could try doing a engine cleaning with Auto-RX. I would guess that the rings might not be doing their job because they are filled with some sludge and other crap. Auto-RX is designed to dissolve sludge and other crap inside your engine slowly, unike those quicky 10 minute engine cleaners which don't really do anything. You can read more about this stuff on bobistheoilguy.com and auto-rx.com. Two bottles of Auto-RX, oil and and a couple of filters would be about $100 Canadian which is a lot cheaper than taking the engine apart :x . Also, have the checked the breather on the valve cover to see if it's plugged?
By the way, I got my Auto-Rx yesterday and I'll be putting it in my car (1994 Golf TD) on the weekend. It doesn't burn oil at all with just over 250,000 km but some people have reported getting a 1-2 mpg increase in fuel economy even with a good running engine

Humm, good to know farkman.
I will tried this in my old 1.6TD. Its smelling oil little bit and consume an quarter pint every 1000 kilo. :wink:
I'll try the Auto-RX sound cheper than an engine rebuild.
Failing the Auto-RX, are there any adapters to fit 1.9TD motors for doing leak down tests. I'd rather conferm the leak before I tear the motor apart.
Also What is the role of the large disc shaped filter/diverter thing at the top of the engine connected to the crankcase vent system and the air intake?

This may not apply to your '95, but on the older VWs the crankcase vent is made into the valve cover and will get clogged up and acts as a siphon, pumping the oil into the intake or airbox as the case may be. Removal of the cover and soaking in a good cleaner (such as GM Top End Cleaner) while heating the outside with a propane torch is reccomended to break up the sludge. Be careful, this cleaner is flammable and breathing the fumes is not good either. :shock:
A buddy of mine just bought a Mann Filter ProVent 200 in Canada from a company called REM Equipment who sell all the Mann filters in Canada. Apparently they are willing to ship anywhere in North America. He paid 230 CDN plus shipping and taxes.
It works like this. In jetta TDI engines, air enters the crankcase through the oil return pipe on the turbo, called blow-by gasses. These gases cause pressure that can affect engine life, but also carry harmful oily deposits. This means that if left alone, the intake pipe can become very dirty and can cause reduced performance, fuel consumption, and engine life. The ProVent simply filters the harmful oils out of the air between the turbo and the intake. It does not change the route of the tubing, but simply adds a filter. According to my buddy, this has made a huge difference to the way his engine runs.
It seems that Volkswagen just approved it as a certified aftermarket product, so it shouldn't harm the warranty. It came with a full warranty and all the other stuff that came with buying it from a real dealer. This item seems to be almost a must-have upgrade to all TDI engines. I would recomend to anybody that wants one to buy from these guys based on his. 1-800-668-8736 or
