Coolant leak & mixing with oil

nick124 · 09-26-2012, 08:54 PM

Went to she shop today and saw my Supra in the air. Stopped in and he has it all taken apart and he was right. Just that gasket. He showed me how it was leaking straight down into the oil pan. He also showed me that the car actually does have a MHG that appears to be working. The car will be done tomorrow and ready to go. I plan to run it a few miles and change the oil and filter again.

I am happy that there is nothing else wrong and I didn't have to go through the headache of replacing the HG or anything else. Once I get it back, I hope to upload some pictures and write a description of the things that I actually know about it :P

Thanks again!

If you could get the part number for the gasket from your mechanic I'd appreciate it. Even looking at the Toyota EPC I can't figure out which gasket could allow a leak between the oil and coolant circuit. I've stripped more than a few of these engines and rebuilt a couple and I'm stumped. This is a 7M and not a 1JZ or 1G, right?

I'll get the part number for you when I go to pick it up. I wish I got a pic of it to post. I thought about that when I got home. Yes I have the 7mgte...I can't find anything helpful to show you on the internet.
