Hi all,
14 V with all basic bolt on mods, cam, etc. Did a short street pull and afterwards had what I think is steam coming out of the MM catch can. No milky oil, good oil pressure, nothing out of the exhaust. Intercooler brick seems solid as I pressure tested it. I guess a compression test is next, but why is there nothing coming out of the exhaust? Server won't upload video, but it is basically billowing out of the catch can breather. TIA

How is your catch can piped? Is only running to the valley on the supercharger or do you also have a catch can for the heads?

Oil does not steam, water does!

Put your coolant pressure tester back on, and leave it on for about
a half a day and see what happens.

Then, if you must; drain the oil and look inside the filter.

I need to get a coolant pressure tester and do as you suggest. I thought for sure it was the brick. I had removed it and put it in water and pressurized it, no bubbles. Leak down test is another thing I should try. I still don't understand why no milkshake in the oil or anything out the exhaust.

From what you have stated, I believe you do have a problem with the brick.
Just a guess though!

Warm the car up, put the pressure tester on it, and let it sit.

If you drain the oil, attempt to only loosen the drain plug, as water will settle on the bottom of the oil pan. Once loosened sufficiently, water will drain out before the oil will.

You have owned some nice cars..:)

I drained the brick and disconnected the water lines then fired it up, same thing happens. I am running e85, it was a fresh tank. I have been on e85 for the last 6 years. The only thing that has changed was a transmission rebuild, which is the reason I got on the gas. I wish I could upload the video.

Still have all the cars, lol thank you!

If the pressure testing continues to show no leak, then I suggest you change the oil and filter.

The negative regarding E85, which is an ethanol, is;
any ethanol (wood or sugar) tends to attract water.

Oil and filter changes must then be completed much more frequently. . . .

Cheers

Thank you all for the advice.
It does smell like coolant, which is why I was certain it was the brick. Definitely not oil. I will try to post a link to the video.

Pull the line from the valley port and check for steam. The brick may be good, but the O-rings may be old or damaged.
I will try that. I did disconnect the water lines to the brick and it still had steam though. I will post results tomorrow. Thank you
