bad luck water coming out the timing cover seal

[tara]

hi guys,

just finished the installation of a custom made exhaust, and here again another issue. coolant is coming out the the timing cover, it seems that it comes from the seal on the crankshaft. is it possible ???
thanks

I struggled with coolant leaks for a long time trying to get the timing cover and water cross over sealed. It's likely coming from there somewhere, not the crank pulley seal itself. I'd keep looking.

yes i have read all your posts about this issue. permatex stuff and many gaskets kits.

i have already this but it doesn't look complete

there was a straight spray of coolant out of the pulley

The photo you posted is missing the water crossover gaskets. I don't recognize that round gasket at the bottom. If coolant is spraying out of the crank gasket then your oil pan is full of coolant.

Am I remembering right that it's a Buick? That would explain (to me) the shape of the gaskets.

Fluids have a tendency to adhere to parts and flow down to the lowest point on the engine before they drop.

Getting a flashlight in there and following the path of the liquid, even if you have to use your fingers to follow where you can't see, will tell you what exactly is leaking.

If it is indeed the radiator, you'll need to get in there and make sure your hose clamps are tight. That's a cheap and easy thing to do that might solve the problem. Next thing to check is the cap to ensure that it's sealing properly. And then the overflow outlet. If you're overfilled with no overflow tank, you'll get fluid coming out. If it's not that, you need to find where the radiator is leaking. Also, keep in mind that sometimes new parts are defective so don't let yourself fight the problem just because "it can't be the new part I just installed". A buddy of mine spent over $1,000 trying to fix what was a defective-out-of-the-box $25 fuel pump.

It's an amc 327.

That's why I don't recognize it.

Still, the steps to diagnose are pretty universal.

will remove radiator tomorrow and see where is the leak, keep you posted, thanks

Might want to do as suggested and find the leak before pulling anything. If you pull it, you will have removed all of the antifreeze and no more leak. Cannot find the leak without fluid leaking from it.

I saw the coolant jet coming out the center of the radiator against the pulley
I got an extra radiator

More than likely one of your core tubes split.

it was very hard to find a radiator for my 327, i found it on ebay. 3 rows aluminium, but it was the exact model for my car. it looks like china stuff, not expensive, but i didn't find any store which had the right radiator for my car

You were right a core tube is broken by the fan which rub on it
Cos i i had installed the radiator too close to the fan

I m now installing a new radiator from a different model which fit better
Gonna finish soon keep you posted

Glad you figured it out.
Something to watch out for is motor and transmission mounts that allow too much movement. Under acceleration and deceleration the transmission will rise and fall with torque. When it rises the fan is pushed closer to the radiator so good clearance is essential.
