Tired and frustrated with the glycol in oil leak..

[Jerry Clayton]

I magnified #4 up to 1000% and it sure looks like a crack----

A comment about nitrogen and air being mostly nitrogen----we breathe because of a build up of carbon dioxide in our res systems----a lung full of nitrogen will cause no co2 and you won't breathe---just go to sleep

The slime will go away with proper/adequate ventilation of the engine---it could be building up because of your two breathers. not the correct balance of flow and also the engine can be sucking in outside vapor on cool down---the ribbed covers agrevate that condition (top of motor cools quicker than bottom, alum quicker than iron)

you are pretty upset at this and it shows in your responses--

have you been a taster of coolant for very many years???

does look like a crack

I agree--- if you have a sniffer available your method will work better.

Most of us are not that well equipped.

Good luck with your search, I hope it turns out to be fairly simple to rectify.

It's not a crack, I promise.

As I recall, on the breathing Nitrogen the statement that was made "One lungfull and you're dead". It takes quite a few lung fulls to put someone down. It's inert and non-toxic .... but as you hinted it displaces air/oxygen, like quite a few gasses out there does.

About 40 years worth of intermittent coolant tasting. It goes along with the many years I used to wash my hands in MEK!

The slime WILL NOT go away. It's from coolant leakage, not outside humidty being sucked into the motor and condensing up top. I had ZERO sludge while that block sealer I was using worked (6 months worth). The block sealer had nothing to do with proper crankcase ventilation.

I'm trying to come across as not being too upset, but I am... I feel I need to answer everyone's replies as I was the one that asked for everyone's suggestions in the first place. I've got a degree in Automotive Technologies and a non-current ASE master certification so I didn't fall off the apple cart yesterday.

Funny, I've not heard much from the internet experts much today?? Google must be down... Pat, are you there???? heh, heh.... Sometimes it's good to be bad.

Yes, I'm here. But I don't know what's causing your leak. And I thought you could breath a little bit of nitrogen and it wouldn't hurt you....

Undy Dave what would happen if you charged the manifold with Freon? you have a sniffer like mine that will pick up very small leaks and the dye will leave a stain wheres its coming through?? Brain farting, Pat's not helping yet!!! Rick L. Ps if this doesn't show anything, do the block the same way if you can get a good seal. By the way Pat like the dentist office for his fix.

Not knowing never stopped you before... With everything else that's been through my lungs, Nitrogen would be my least worry.

If you keep pressurizing everything, and everything keeps passing, all I can think is that you just start blindly replacing gaskets. Sorry.

Dave,
Just grasping again but this thought occurred:

A. Started after the intake change-right?
B. Goo only in VC's-right?

Guessing that water is entraining into the oil feed at the rocker pedestals in each head. That would contaminate only the valve cover area. Don't know where such water could come from and don't know why the goo doesn't go down the corner head drains and contaminate the valley/crankcase areas. You don't oil through the pushrods right?

Just trying to get someone smarter than me to think away from all the gasket/head/porosity/testing stuff beat to death here. You've covered all that in my view.

If you haven't already-get KC to listen and offer a thought or two. I KNOW he's not responsible for this problem.

Getting a headache.
