Question about 2006 Volkswagen Passat
Thought the oil leak was with the drain plug, change oil and in the process had the dealer replace the drain plug the oil leak still happens.
workshop says oil leak is with flywheel assembly. not sure if they are telling the truth, the oil color is more brown/blackish.
is flywheel oil same as manual transmission oil and is there way to confirm this?
how much would it take to diagnose and fix it
Well this is an expensive repair as such because of the time involved,a reputable garage would check the clutch and gearbox spigot shaft as a matter of course but the seal can only be reached by removal of everything ,if its just a small drip then have it done as and when the clutch needs replacing is the best advice i can give,adding a leak sealer for engines could help as it makes the seal soft again but if the end of the crank is worn then no ,but it could work and often does.and its not that expensive if it saves you a lot of work for now.As for mileage well treat it as a guide only as mileage tampering still goes on and you will never know weither its the garage or a previous owner who didnt want to lose money.but make sure you check oil level in gearbox in case its leaking out of spigot shaft seal .engine oil smells like engine oil but gearbox oil stinks trust me ,trying to get it when it drips up your arms ,,,,.Also as a matter of course check the engine breather as evan a slight blockage here will increase back pressure in engine causing it to leak oil .How long to remove ,,well about 3 hrs roughly if all the bolts come undone on the suspension an hour or so to change seal and check over maybe evan pushing seal in or out a bit to miss wear on crank if any,rebuilding with a strong lad to assist in alignment and moving about another 2/3 hours if it all goes well with no complications .

Rear end oil seal ,a common fault but its expensive to repair although the seal only costs coppers as the gearbox has to come completely out and this will involve dropping the sub frame as well.no short cuts here ,iam afraid ,how bad is the leak ??try some autobox laek sealer additive and put it in the engine oil.also if and when you have it repaired check for a ball bearing blancking plug in end of oil gallery its a possibility ??seen it before .whats the mileage of this vehicle as it sounds like a high mileage reps cars
