So, that's about $0.22/mile for maintenance and repairs. That's high, and would be psychologically painful. But, less so when you consider was deprecation on a new X3 would be.

Frau Putzer's 2018 X3 depreciated just about $10k in the first year and 10k miles, $0.992/mile. The second year should be down to about $0.50/mile.

If your head gasket is leaking, your engine will die VERY soon. If you had to pay someone to do the work you did, you will NOT be doing a head gasket yourself.

Find a new mechanic, because he just told you to possibly destroy your engine.

The INDY said it will cost $4000 CAD for a head gasket replacement. How much for a used engine?

I will closely monitor the engine oil level, I checked the engine oil level every single week. Previously, it totally leaked 3 Liter of engine oil with head gasket leak and valve cover gasket for last 2 years. Now VCG was fixed and not leaked any more. Let me see how much oil will it leaks for one year with only head gasket leak. The INDY said it is very minor. Thanks.

Yes, much better than a new one. Plus the car purchasing cost, it is about 18300 CAD, I am happy about it, just try to make the cost less and less when me and E83 getting older and older. Thanks.

Do either you or your mechanic know what a head gasket does?

I was thinking the exact same thing.

OP, these engines aren't known to have head gasket issues, unless overheated at some point. If the head gasket is leaking, it needs to be addressed ASAP, as some chemicals in engines are not meant to mix...

No, I don't know. I will call the INDY. :)

Thank you for the help.

Maybe he meant the valve cover gasket.
VCG has been replaced with the cost of about 690 CAD 3 months ago. I will call the INDY and let you guys know. Thanks.:)

Maybe it is not head gasket, I will call to confirm, but it should be still leaking somewhere. I just changed engine oil last week by myself, no mixed chemicals.

I’m betting the actual expensive leak is the oil pan gasket... a head gasket’s primary purpose is to seal in the products of combustion and preserve compression. Preventing oil/coolant mixing goes along with that goal. We’ve replace dozens of head gaskets over the years, and I can’t think of one that manifested itself with an external oil leak.

If you have oil in your coolant, well... it’s time to rip the thing apart... And not overheat it in the future.

My INDY replied my email. It is not head gasket leaking. He said it is main seal, between engine and drive shaft? I don't know what that it is.

Very minor, can held for couple years first. I will monitor the engine oil level see if I need to refill it in future. Thanks.

22 cpm is decent for paid work with some refurbishing expense on a new to you car.

A rear main engine seal is a good one To learn about and practice to do yourself. It***8217;s stupid work worth $10 an hour, not$100.

One that requires pulling the oil pan and transmission on these it seems.

If it is leaking, the pan most likely is too.

Shouldn't have to pull oil pan to do the rm seal. I suspected my rm seal was leaking prior to doing my oil pan gasket. It wasn't. The way these oil pan gaskets fail, you can end up with oil all over the place, but especially the rear corner of the oil pan where it looks like it might be running down from the rm seal. My bet is you've got an oil pan gasket failure that is fooling your indy (not that he's a fool - oil leaks can be very deceiving). The oil pan gasket on the N52 is simply not robust enough to last for a long time. It uses a very thin rubber that hardens over time becoming incapable of sealing.

Thank you guys so much for the help. Now I knew 2 more probably leaks, REAR MAIN SEAL or OIL PAN GASKET

I will do some oil cleaning this weekend using brake cleaner. Then check where the oils comes from. After VCG was fixed, not much oil leak noticed ...

Found your post about 2 years ago back in 2017.
Really hopeful

Mine is also leaking from either/both the rear main or oil pan. Both are major jobs to fix, so I begrudgingly live with the drips on the garage floor. Some have had luck in replacing or re-torquing the oil pan bolts, but that didn't help mine. There are threads discussing the job of replacing the oil pan gasket if you search. Replacing the rear main will mean removing the transmission (or engine). Either job is probably an all day or all weekend affair for the DIY'er.
