Hi,I have a 1986 VW bus with the 2,1 l petrol EFI engine. It smokes when starting, but not when running. Pulls all right and do not use too much oil. I think it might be the valve stem guides being worn, letting oil run into the cylinders when standing, and being burnt off when starting. Can this be repaired without taking the engine out? Big job?I also have a question on the bushings for the rear wheels, the old girl is squatting like a girl taking a p.... Can these be adjusted with the car on ground, or should it be done whit the wheels in the air?Best regardsJohannes O. BorgeNorway

Hi, my name is XXXXX XXXXX X am at your service to assist with your VW problems. Welcome to Just Answer.Unfortunately the engine will have to come out in order to remove the cylinder heads. To replace the valve guides is also quite an undertaking, as the cylinder heads have to be heated up in the oven in order to remove the valve guides. The cylinder heads have to be heated once more in order to install the new valve guides, and the new guides have to be reamed after installation to obtain the correct valve guide clearance, but your local cylinder head specialist at an engineering shop will know how to do all this. They will also grind the valve seats and valves and re-lap them to obtain a good seat, so by the time they have finished the cylinder head will function like a new one.If you are going to remove and replace the cylinder heads yourself the cylinder head bolts need to be re-torqued at 45 N.m.Your vehicle has rear wheel bearings and not bushings and you will require a special puller to remove the bearing from the side shaft. You will have to lift the wheel from the ground and remove the split pin and axle nut, then the brake drum will come off and then there are four bolts retaining the bearing retainer. Included in this bearing retainer are three different oil seals and they will also come apart and will have to be removed and replaced.The axle nut torque setting is 160,5 N.m.Should you require further assistance do not hesitate to ask.Regards, Martin.
Hi Johannes,I have just reviewed my previous post and noticed that I had a "finger fault" - it should read two different oil seals!I apologize for any inconvenience.Regards, Martin.
