LYO auto oil seals for Audi

LYO auto oil seals for Audi.Remove the oil pan bolts. There are a lot of them and they are fine thread. This is where an air ratchet comes in mighty handy. The inspection cover is inside a lip on the pan (I found out the hard way after unbolting the pan, that is why the cover is still attached with the pan down). Using a rubber mallet or screwdriver between the block and pan, drop the oil pan. The rear will want to fall completely and the front will hang up on the crossmember. According to my Haynes manual, I should have used an engine hoist to hold the motor and removed the engine mount through bolts and lifted the engine up 3-4". This would have made removing and reinstalling the pan much easier. I did not have access to one, so it a bit harder getting the pan in and out.
Work the pan out from under the truck and be careful not to damage the oil pump pick-up tube. This is where the cardboard comes in handy. Not only is there a bit of oil still in the pan, but every part of the block starts to drip oil everywhere.LYO auto oil seals for Audi.
Clean the inspection plate and straighten any kinks and warping.If you are replacing the oil pump, remove the pick-up tube from the old oil pump, unless you will be installing a new one as well. It is simply threaded in.
Now it is time to remove the rear main bearing cap. There are 2 bolts holding it in place. It is a large cap, not like the usual style. You may need to pry it with a screwdriver. It is fairly heavy also. Use caution when removing it since the oil pump driveshaft runs through it. You want to inspect that driveshaft for wear and replace if needed. Clean the cap and remove the lower half of the main seal. Do NOT damage the main bearing! Install a half of the new seal into the slot. Lightly oil the new seal prior to installing it. The side with the paint stripe goes towards the rear of the truck.
You might as well check the teeth on the flexpate and anything else you can see in there.LYO auto oil seals for Audi.
New oil pump. Thoroughly clean the pick-up tube and thread it onto the new pump, if installing a new pump. Be sure it is properly threaded to avoid sucking in air at that location. Prime the pump by turning the pump and pouring oil in it until it comes out the other end. Do this whether or not you are replacing the pump.
Its now time to remove the oil pump. It is bolted to the main bearing cap so it needs to come off anyway. Might as well replace it since it is off. Carefully remove the 2 mounting bolts on the oil pump flange. Do NOT remove the oil pump cover (hex shape). Check to see if there a paper gasket stuck anywhere. My truck did not have a gasket. Also, there is a large column of oil above the pump, being held there by the pump. Once you break loose the first bolt, another 1-3 cups of oil starts to come out, be ready with a bucket.LYO auto oil seals for Audi.
Clean the oil pan with solvent and inspect the mounting flange for warping/damage. Mine had a bit of rust on the inner surface the was more or less removed with the solvent and wiping. Clean the gasket surface also.
To replace the upper main seal, you will probably have to use a screwdriver and small hammer to get the seal (ends marked with red arrows) to slide around the crank. It is a rigid piece, so it will follow the crank shape as it is removed. Only use the screwdriver to start the seal moving, then switch over to a needle nose pliers to pull it the rest of the way. You do not want to scratch the crank. Do not damage the oil pump driveshaft (also marked with red arrow). LIghtly oil the new seal half and with the paint stripe side facing the rear of the truck, carefully insert it into the seal hole.

Push it all the way around until it is flush with the block on both ends.LYO auto oil seals for Audi.
