VWs Never Leak Oil�

just mark their Or so, you�ve been told. most people think VW air-cooled engines are nothing but of leakage, and that there are two of these � engines that do and the ones that will. I can honestly say that this is much true, after owned an air-cooled VW in the past, are many things you can do to prevent or at least minimize them. You have to drive a VW that enough oil to make the Valdez like a drip. This will deal with the on finding leaks and fixing the

Let me start by talking a bit about transfer 101. For an air-cooled there is no radiator full of or water jackets in the heads and block. Water is a very means of cooling. Oil, is not very efficient at keeping cool (compared to water, is). It makes you wonder how air-cooled engines get by like do, but there are millions out there still rely on oil and air as their coolants and do so in the most adverse Here�s the point�the oil inside the is responsible for transferring heat from the crankshaft, connecting pistons, and heads head That�s it! That�s all the internal have to cool them. If you the oil, you�ve just the engine. On the flip side, all the oil leaked over the outside and everything is actually hurting the of the engine to keep cool, you don�t have a full 2.5 to transfer heat. Bare is a lot better at transferring heat to the air than metal with the oil The point � keep the outside of engine as clean as you can to aid in keeping the cool. That�s where I in with the oil leaks.

Begin your leak by thoroughly degreasing the engine on top and Get two or three cans of degreaser and your VW to the nearest quarter-operated car Be sure to take a bottle of alcohol (to dry the distributor in case you get in it), something to cover the with, and wear old clothes. all engine surfaces with and wait a few minutes. Now blast it all off the pressure hose. This may a couple of times if your is really caked. Remember to do the too, including the transaxle. Now it home, park it, and let it cool. If you had to a little distance to the car wash and or had a bad leak to start with, you notice what is leaking by Is it coming from the hole the transaxle and engine mating (transaxle seal or rear engine seal). How about the top, apparently from the cooling shroud (oil grommets). Or, around the oil filler area (breather deflector incorrectly or breather-to-filler neck is defective). If oil is covering just the of the finned oil sump, it could be tube and/or seals, cover gaskets, piston not sealing, or the oil sump cover is or is otherwise not sealing properly. the air blowing across all the engine will also blow the oil so if you drive for too long, you may not be able to the leak.


Let�s take a systematic to stopping the leaks. I�m going to here that you haven�t had the out of the vehicle for years. Chances are everything is leaking enough to pulling the engine out and sealing it up. this, go ahead and pull the Even if you�ve never it before, it�s not a difficult and might take a first-timer two or three hours. After it is go ahead and replace the transaxle shaft seal. Even this does not have to do with the engine, it can still a big mess of things and make any leak tracking very Once you have done remove the flywheel and replace the main crankshaft seal. pull the heads off just far to replace the pushrod tubes and Do yourself a favor and buy new pushrod They are cheap and old ones may be around the bellows at each Be careful when pulling the that you do not pull the piston out with them unless you that leaks are coming around the jug-to-crankcase areas. you button all that up, replace the oil seals. This is usually a of a very big leak, since oil is pressure when coming out of the old seals. Make sure valve covers are not warped and you put new gaskets in these as well. I tell you that I have had good success with the steel valve covers and If everything is straight and sealing are not gouged, the valve covers seal with no

sealants whatsoever, and no leaks. Oil sending units love to when they are a bit old, so that $5 sender. This care of the really big stuff. you have the engine out, is easier to get at, so let�s wrap it up way.

Now unbolt the oil filler/generator stand. is a metal oil deflector with between the stand and the case. The louvers should be pointing and the openings to the right. If this is not the oil will be thrown all the way up the stand and out the Use a little silicone sealant on sides of this deflector and the stand back on. Take off the oil If the sealing surface of the breather is flat, a thin o-ring the of the upper part of the stand seal very nicely, or use a amount of silicone on it and bolt it down. Make sure the seal on the oil fill cap is in good as well. Pull the distributor out and the o-ring on it with a new one. I can say with confidence that needs a new o-ring on their since this is an easily-forgotten Now pull the fuel pump and out. Check to see if the spacer has a in it. If so, replace it. Use one thin gasket on the and one on the top of the spacer, and a small amount of This should take of things on top.

Bolt the engine back in and to change the oil. I bet your old cover is beat-up and worn, so get a new They are relatively inexpensive. If engine doesn�t have many miles on it, you might use 10W-40 oil. Why the thin The thin oil will lubricate and much better on cold and will transfer heat better than the heavier oils. The downside is that it tend to seep through and around seals more so the thick oils. Also, the mileage or harder-driven engine need the 30W or 20W-50 oil. about synthetics? I wouldn�t full-synthetic oil. It flows so it will cause leaks were never there especially on the air-cooled VW engine. Use one of the oil blends and you can have your and eat it too. Ask Herschel Dalton this one, as he has had good with the blends.

As you can see, are many areas to look for eliminating oil leaks on a VW engine. you do this, however, keeping the clean and staying on top of the leak will be much easier, and you be rewarded with a cooler engine that you won�t to add a quart to once a week. It also make other repairs much more without all that crud all everything.

Make sure you read up in shop manual on performing the I have mentioned above, as obviously would not be room for every step in this See you at Fox Ridge on December 12 th for a bratwurst
