JJ's 2nd Rebirth Of My Junkyard Dog '75 200

Needless to say, I am very discouraged. At this point, I don't really know what to think. It is acting exactly the same that it was before. No water in the oil, the heads were checked out to not be cracked. The water pump is an AC Delco branded one that was on the old motor, so I don't think that is the problem. Maybe the block is cracked? Foam, lots and lots of foam.

I have a 345 in a '79 Scout out here that turns, maybe I just try to get it running and cut my losses..

Ideas are welcomed.

That sucks JJ, don't get me wrong, but that picture is kinda cool. Rather artistic.

 

could you close off all the water ports and put air pressure on the block and do a leakdown test on the engine?

 

Dang. I'm sorry about the bad news. I wish I had an answer for you.
Stay positive, it will be ok.

 

Do the water pump clearance test. Just to be certain. Also maybe some of that crud that was circulating the first go around is somehow blocking flow at the water pump. Make sure the radiator is not clogged.
Other than that - I got nothing.

 

would that show a cracked block? I appreciate the thought.

Thanks Randalll,

I will check out the pump, it seemed OK on the last engine. MeeMaws undies didn't have too much trapped particle in them so I feel like scale was cut down.

We do what we call hydro and pressure tests on lots of our equipment...
The hydro test involves pressuring up water in the system...you can put some ungodly pressures on something using this method..it uses a pump to build high pressure
The air pressure test is the same thing, just with air only..
We install test plugs in our piping to block them off..then at one point we have air fittings, valves,gauges..
We pressure up the system, close the valve and monitor the gauge..if the pressure starts dropping there is a leak..
If you could plug off 3 of your hoses and use the one for putting in air..put 15-20# on it and see what happens...
It may be though that it wont leak till the engine heats up and expands..
I know itd be difficult on a engine to find a leak this way but it's a thought..

 

Good ideas. Nine careers ago I performed leak detection mostly on water supply systems. Water is far superior to air for a number of reasons with regards to leak detection.

Something tells me that coolant is just not adequately being circulated throughout the engine?

 

Man sorry to hear that J.J. are your t-stat and cap good? I believe you said you was running a newly refurbished radiator so that shouldn't be a problem and you have a shroud I seen in the pic. What did the gauge say and was it just doing this at idle? and cooling down when moving. Hang in there you're to close to give up now.

Thanks gents! Great ideas and will get to where I can perform those! Greg, I will be reaching out to you to plumb your expertise soon! I am away from all of it for now dealing with some family (not bad) issues. But..

I had a thought too. In the interest of not filling the heater core with crap from the engine, I had bypassed the heater core, and used threaded fittings with a hose clamp in the ends of the heater hose. After I ran it the 1st time after rebuilding the heads and it was pressurized, it leaked from one of the hoses, and after it got hot and the spew stopped from the over flow tank, I could hear it hissing from the heater hose. So...

Correct my work:

If I take off the belt so the water pump does not turn and it doesn't foam (not going to run it hot) and water is not circulating, then it would be either the water pump is not operating correctly as RinTX suggests or it is or was drawing air in from the heater hose, right?

If it DOES bubble and foam, then we would know that there is a bigger issue than water pump and/or heater hose.

Thoughts?

that would do basically the same..but not as good as a true pressure test ....
but...make sure your hose blocks are air tight,,if you get it all completely full of water , leave the rad cap off, pull the belt off, crank it up and watch for bubbles in the radiator..it (hopefully) wouldn't have any bubbles...if you see bubbles, it aint good...

 

Well, Ive been out of the loop for a couple of weeks. My 84 year old mother asked me to come out and help go thru my deceased fathers stuff 8 years later. That was quite an event. We found all kinds of things and old pics. I stayed up in my Ouray Colorado house for a few days. Here is my local friendly deer that came in around sunset everyday.



Also to share some old family pics. My sister and I in front of his 1970 Travelall.



Found the key to his 1970 Travelall.




Got to hang with Ed and Kate for an afternoon and check out his 80 build. WOW!



Oh yeah, after catching up this afternoon, it was time to try and start the truck and asses it. I turned the key and it went "click". There is always tomorrow. HAHA. Maybe Ill know whats up before lunch.

That smurf blue Scout does look good JJ...dont tell Ed though
It's always odd when I was out west to see so many deer and elk in town...around here they wouldnt last long doing that...somebody would have em on the grill...

 

I'm so sorry that you had to lower yourself to my level JJ and posting a pic of Barb. Surely you have more pics of a 392 overheating?

 

...or lunch...

 

Man j.j. here is some Salve to put on them bruises they are giving you a beating. Hope for some good news on the 392 tomorrow.

("Surely you have more pics of a 392 overheating?")....
good one..!!...

 

Man. Way to kick a guy when he’s already down.

Rumor has it another Scout followed him home from Colorado.
