Indy found an oil pan leak instead of the suspected oil cooler issue and also a broken left motor mount. Reseal the oil pan ~$1,800 and replace Engine and tranny mounts ~$1,300. Does this sound about right? Wondering if any of the labor charge is actually redundant if done at the same time. Any insight would be much appreciated. GL is a 2015.
Oil pans usually don't leak. Double check his finding with other mechanic. Or pressure wash the siht from down the engine and see if it will appear again. For engine mount - way too much price.
Motor mount issue was discovered by the indy. I took it in for the oil leak, wheel alignment and transmission service. 80K is the mileage, I know a bit overdue for the trany service. Hindsight, perhaps a slight vibration on start and idle but nothing severe by any stretch.
Got this link with the pics of the pan leak and motor mount. https://xoxocar.com/inspection/d1499...991?sb=rtg&b=0
Any idea on the book hours to change the motor mounts? Their rate is $117/hour. The said the pan seal is very involved including front differential removal or displacement? Much appreciated....
Attached file is an example of weep holes on om642 So, as you can see there is a weep hole in front as well. I am still suspicious that it is your cooler leak, not a pan. I mean - pan normally is sealed with polyurethane adhesive. That siht it hard to take off, not talking about possible oil leak. Usually it is either pan been hit real good or someone took it off before and use cheap siht RTV sealant.
Moneywise - they will have to drop front subframe with differential too take pan out or lift engine up. So yes it will be that much for the work they charge. Just look around there are lots of people trying to make dove. You can always find cheaper place.
Now there is a rip off. If they resealing oil pan - you don't have to pay full amount of work for changing engine mounts - because they will have to disconnect those anyway and changing it will be unscrewing one bolt. Transmission mount is an easy fix.
Thanks for the pic on the weep holes. It helps to understand that I may have a small oil cooler leak that will likely be coming due someday. Indy says slight leakage from weep holes so will clean up around them to help monitor for oil cooler leak. But I agree with you the oil cooler was what I suspected to begin with. - will have to keep a close eye on it. They are also replacing seals on the fresh air tube - I don't have a clue what that is or how it's related at this point. I did call 'em on the redundant work quotes for the motor mounts - they said they would "work with me" on that - do you know about how much extra work is involved since they are already dropping the differential, etc for the pan? Great information - grateful...
Don't recall hitting the pan or otherwise anything that would have caused the seal to leak - only other work down under that I have had under warranty is the entire def system and exhaust system - glad it was warranty @ ~$10k including transfer case leak they discovered during the def repairs. Maybe the sealer guy on the line had a hangover when it was built? Ha. Haven't a clue but will ask if any indication of cause when it is disassembled.
Just reread your reply arsupisemnet - is it literally just unscrewing one bolt for the additional work? and the transmision mount - seems very redundant indeed they did say they would work with me - just want to confirm how much if any additional work so I approach them appropriately. Thanks!!
Engine mounts resting on subframe. If they resealing oil pan - they have to disconnect engine mounts from subframe either way.
Now your engine mount attached to engine with one bolt. So literally to change engine mount during oil pan sealing is to unscrew one bolt on top of it and put a new one.
Transmission mount usually connected to cross member which is usually attached with four bolt to car body. Mount itself usually two bolts to cross member and two bolts to transmission...
That is all the work to do it.
The only thing they suppose to charge you extra - is a time for changing transmission mount. Period.

Before resealing oil pan - just as precautions - discuss the outcome there their actions if it won't resolve oil leak. What if. Discuss it with the "manager". And have it recorder on your phone - easy task to do.
I am still convinced that it is not an oil pan. But a oil cooler leak.
If the issue is not resolved - no reason for you to pay.
Ha. Just got the invoice texted to me with 4.5 hours for engine mounts - I'll add that to my list of invoice issues including trany service $65 over quote and clarification on "black sealant" for oil pan seal. Great advice on ensuring that this fixes the oil leak and it is not infact the oil cooler. Initial quote also stated "slight leakage from the weep holes so in my text back to them I will seek clarification and assurance that they in fact resolved the oil leak. Noted in the invoice was dipstick tub seal (Lower) which I had noticed leaking during an oil change some time ago as well as the rear crankshaft seal so I'm sure there were other contributing issues. All in all the shop seems to be very clean, professional and honest but as stated - everyone wants to make money so trust but verify is my approach and you arsupisemnet have been of great help. Truely appreciated. I'll post the results of my efforts tomorrow after I pick it up.
Rear crankshaft seal could be your oil cooler leak as well.
I have project car I got for a change 2009 e class with same diesel engine. I will assure you that my oil cooler leak looked like rear seal leak and everything else leak. I had oil literally dripping from the motor as it was running. Once I did oil cooler seal replacement - have completely dry engine.
I share the oil cooler leak concern. I asked for clarification on “slight leakage” from weep holes. Would there more significant leakage with an oil cooler seal leak?
If you will look at the picture of engine block again you will see some relief areas which are lower than weeping points. Slight leak means all those areas are full with oil which means it been leaking for a while. Now it is only a matter of time for it to leak faster and faster. And it is well documented issue with OM642 engine.
Rear seal was not leaking but replaced since pan was down. Prudent me thinks for little additional cost. Other minor seals replaced as well not the source of the leak but just good practice at little cost. Overall very pleased with this particular shop. After a bit of banter especially on the 4.5 hour charge for motor mounts the Service Manager knocked off a few hundred dollars. Confident this leak issue was not the oil cooler - yet - will definitely keep an eye out for leaks over the next few weeks. I very much appreciate the knowledge and experience shared that enabled me to more effectively deal this issue.
