No pressure in radiator...need some help.

So there are ports between the timing chain cover and the block. I was unaware of this. Just thought there were oil ports there. Thats gotta be whats leaking. I'm wondering if I should just pull this motor and replace all the gaskets/freeze plugs.

No ports, a couple of the bolts hit water. Doesn't make sense to me, but I had a seep and that's what I did to cure it.

No need to pull the motor, just drain off some of the coolant and put some non hardening sealer on the water pump bolts and run them back in a see what happens.

So coolant doesnt flow through the timing chain cover. Pulled my "Small block mopar" book out and took this picture. I circled in red where I am seeing coolant leak from. These are not ports?

Common problem there. Slather those 4 bolts with ant-seize; they will rust to the block.

yes ,thats where im guessing the water is coming from. coolant flows in and out through the water pump. the bolts also protrude into the water jackets.

if it were me, and i had water coming out right there, i would have to get out my balancer puller and go to work and re-seal the timing cover and water pump. thats not to say that it would not seal itself up, but my experience has been, once i have developed a leak like that, it doesnt go away. i also use a little permatex on the bolt threads when i put them back in. and hopefully your timing chain doesnt look like the one in the pic lol

Yeah, I agree. I think it's time to freshen this motor up. I've never done anything like this before, so I will be a good learning experience for me. I bought the car already restored and have no idea how long ago it was done. Got a couple of relatives that have torn down motors before, so I am looking fwd to getting my hands dirty.

these are great little engines to work on and really straight forward. but i must warn you, once you get the bug, its hard to shake. i grew up with 383 and 440s . but i am really impressed with what these guys are doing with small blocks. i have a few now that im playing with where , in the past, you would never find a single one in my garage. keep us updated on your progress.

Wow, I never noticed those when I had mine apart, sorry for the mis info. The bolts that are right there are the ones I was referring too, they go into the water jacket. Common leak. I would at least try and seal those first and see what the result is. Easy enough to do.

No prob...I was gonna give the bolts a shot first and if it still leaks I'll have to start tearing it apart. I don't like the thought of oil and coolant mixing. Thanks for the advice!

I kid you not, I built one and did not hit the bolts with sealant that enter water jackets and it seeped water.. The bolt threads will not hold 10lbs of water presure..
Looking forward to the repair and let the engine run :glasses7:

The timing case cover actually wears out and will develop a leak (usually at the side near the top bolt holes). The water wears the aluminum and thins it out to a point where there is no material left. I've had to replace 3 timing case covers over the years due to this.
