1987 300td Turbo Leak +
 

So my turbo is leaking a bit of oil from the top and a bit more from the bottom. Nothing drips onto the pavement because of the splash guards, but it's there. Also have a small leak from front crank seal, and something else on the other side of the block, probably head gasket related. Also a bit from right under the ALDA. All minor IMO.

I get good oil pressure, had the sender replaced and run at 2 at idle and up to 3 when driving. Don't lose much oil either, maybe a half quart every couple of months. Car is daily driver.

My question is, how much leak is too much, or better yet, how long can I ignore the turbo leak? (I've heard most leak to some degree with age) I plan to try and take care of the gasket/crank seal at some point but would rather leave the turbo alone.

thanks,

If oil is leaking from the top of the turbo, the turbo oil passages might be clogged up a bit, unless the seal is shot, then it depends how much is leaking.

Turbo Seal
 

It's wet up top, but the real leak is from the bottom. Is the seal something I can do myself? Can't seem to find much info on it here.

it could be blowby oil collecting in the housing leaking out.
got pics?

Turbo Seal Leak - Pics
 

Okay Guys, here are some pics as requested. 1. Just a pic of the whole engine, 2. Turbo leak from the top, 3. Turbo leak from front, and 4. ALDA leak (coming from base). I know the actual Turbo is a bit obstructed, but I wanted to take some pics as is before I started disassembling anything.

I also can't get under it right now, but the leak is a bit worse from underneath the turbo, though now that I think about it, it could be just leaking down slowly from the top. Also, if you any of you can tell by looking if I have a Garrett or KKK I can't seem to figure it out.

Thanks,

Blown seal or worn engine dumping oil into turbo and your intake seals need to be replaced.

I have a good turbo I will sell.

Happy to take it if I need one. Does it matter if it's KKK or Garrett? I can't seem to figure out which one I have. PM me with the price/details if you could.
