oil leak

having a barely noticeable oil drip off my rear main seal I got it replaced only to have it suddenly pouring oil. Took it back In and the shop found these grooves warn into the end of the shaft preventing a full seal. They are only about one thousandth of an inch deep but this is causing a...

Hey all, 4D56, 93 L300. Four days ago, started it up, lots of white smoke. Tried going to the store to days ago, got 1/4 mile down the road and my water temp went nuts, instantly to 228F (have a deli works radiator). I also have a comprehensive sensor system for oil temp, water temp, pressures...

Hi everyone, first off I would like to say thank you for all input and advice regarding the new and exciting issue we’ve been dealing with! *sigh* it’s the end of summer and the van is parked in the driveway. But I’m hoping nothing major has happened.. as per usual. It started with a...

Simultaneously, I added hoseclamps to my Mishimoto catch can setup...

I recently fitted an oil catch can. It's a generic catch can that came with the van when I bought it. It's a '95 L400 S1 4m40. After I fitted it I started to see oil coming from the oil filler cap. I did some research and people suggested a blocked pcv mesh or to replace the cap. I needed to...

Hi All, I have a significant oil leak, and it appears to be coming from the alternator. First picture is before I wiped everything down, second is after - you can see drips forming from openings in the alternator. They don't appear to be coming from the vacuum pump directly, though I haven't had...
