Anyone want to guess where this leak may be coming from?

What year and assembly number is after they stopped using bronze guides?

 

what year is your car?

What color is your gear oil?

 

Redline has the color of engine oil, especially if it is in the car for a while. My guess, without being there, is your $8 orings leak. If the heat exchange leaks, you will see oil in the coolant, or vice versa.

I do not recommend changing the heat exchange itself, unless you find that it is defective. Or, if you have more money to throw at the car, then by all means.

It is easier with the engine out of the car.

 

well, burn baby burn.

 

Hummm. Perhaps a good backflush? Or bring it to a radiator shop and have it cleaned?

Don't have money to bur? why the hell did you buy a 355 then?

 

Look at all the gearbox parts hidding in there.

I'm gathering from your posts that you bought it not too long ago? Probably a "good" deal?

IMHO looking at what you've posted, this car is going to be a project ie; expensive and long. Plan on all summer and boating on weekends. By the way power or sail??

Care to share your VIN?
Mileage?
and buying price?
Your expected "giving her the once over budget"?

I wish you all the luck...

You don't have to burn the money, but you have to know where to spend it.

What I'm saying is don't cut corners, because you'll end up doing it twice.

 

No offense, but those can't be gearbox parts in the tubes. That's where the coolant flows.

I suspect is some silicone that got freed up....or some shavings left over from when the car was originally made.

 

When you do the heat exchanger banjo bolts, check (and possibly replace the washers) in these locations as well.

$8 a pop, times xxx

 

I would get it cleaned or clean it, I have brushes that would work great for that.

I am wondering what that washer looking thing is, some of that silicone the factory used??


This is the filter from the transaxle on my 15,000 mile car. That's all factory silicone. The rest of what you see is just build up in the HE that can be cleaned it's a litte radiator. Take it to a radiator shop and have them clean and pressure test it. Be done with that. you'll know if it's good or bad.

Let me repeat. That picture of the heat exchanger does not have metal from the gearbox. Unless it blew completely out, that is a channel for coolant only. That is most likely shavings from the engine when it was new, a water pump part or some other parts floating in the coolant channels. It is not form the gear box.

The gearbox oil goes around the outside of the tubes you see and does not enter that chamber (on purpose anyway)

Unless you have gear oil in your coolant or coolant in your gearbox, I doubt you have a heat exchanger problem.

 

Gah...that darn hidden filter again. Is that hard to get out? Could you post a blow-by blow thread on the R&R of that thing? I need to pull mine....and it looks scary.

 

Don't write people off based on their "education"... You might be surprised what the "unwashed masses" know... FWIW, I have room to speak, I have Ph.D. but that matters nothing when I am in the room with someone who knows something I don't. You might be smarter, but you might have less knowledge, and in this game knowledge is power.

Be humble and steal knowledge.

Thanks for posting a final resolution. Sorry to hear you had to drop the motor.
