Coolant leaking in my engine and it's not starting up

[breezydun81]

If you pull a plug or two, ground those plug wires and crank it over - does it blow antifreeze out of the cylinder?

Something isn't adding up, usually something that leaks into all the cylinders will hydro the motor.
As well as show up in the oil as it will leak past the rings some.

For it to get into the plug wires from an internal leak, the antifreeze would have to push past the porcelain part of the plug.

Could it be fuel on the plugs??? And antifreeze on the exterior?

First I did that with the spark plugs to see if I still had ignition no antifreeze shot out of the cylinder and for the fuel on the spark plug it wasn't it was antifreeze but it was like a rust color a real light brown even when mixed with the anti seize ???

Coolant leaking into the cylinder from the outside will do that. Had oil do that from a bad o ring on another vehicle.

I flushed my radiator system about a week ago thoroughly and then filled it up with 70/30. It drove fine strong and then all of a sudden I popped the hood to put a CCV filter in and I noticed my overfill tank was about 6" down and I didn't think anything of it I thought because I flushed it maybe I didn't put in enough so I added more antifreeze and then I changed the spark plugs Friday from The originals to denso twin-tip platinum's.I had the guy at an auto store yesterday who I was asking this question to tell me that I should have never put those gun shows in that it's not good to upgrade the spark plugs better to leave them OE copper. That the Platinum could ruin it. Saturday morning I had to replace the crossover fuel injection line and after that is when I tried starting it up and this began.

I'm sorry so what did you do about that situation with the o-ring leak???

Sounds like the water pump might be shot, it will leak right about where you describe.

I just had it replaced about 3 months ago. Plus would it cause coolant to fllod my spark plugs?? I overnighted a coolant pressure tester to find out where the leaks coming from.

Another possibility is a broken hose clamp on the radiator hoses - specifically the lower passenger side.
I had one of those clamps break.

Maybe a bad water pump gasket?

I don't know on the plugs, for enough antifreeze to be on all 8 - it won't be headgaskets or heads at that point - for either of those to be that bad, it wouldn't even think of starting.

Can you do a compression test?

I ordered one earlier it's coming tomorrow so I'll keep you informed as for the hose clamp if you knew me you know my luck is in that good as long as it isn't the head or the head gasket bro I'm happy you know I'll take that manifold intake all day leaking I just don't want to do the head gasket that's crazy money at that point I'd have to sell it man the water pump gasket I've already looked at it from underneath from both sides from up top it looks snug as hell plus they used RTV sealant on the gasket so that thing ain't going nowhere but when your hose clamp broke what did it do just leak on the ground or leak in the engine did any of spark plugs get fouled or wet ??

Depending on how many cylinders are filling with coolant?? Both
Magnum engine heads boe Warp then crack. Drain the loaded cylinders start it then add coolant or water right away only close the radiator cap halfway because you dont want to build pressure in cooling systems. Then drive with heat on and when your out of heat your out of coolant you know what I'm saying???
Fresh reman heads are 300$ with a core. It's not the intake gasket so expect the the heads to be bad

I've already taken the spark plugs out three times since it started doing it just to check them and all of them all 8 cylinders same s*** it's that brown watery coolant you don't see no oil you don't smell any fuel it's just watery brown liquid. So I should drain all the antifreeze out then started up and then immediately add some water and then write it running with the heat on and then when there's no more heat I'm out of antifreeze or water but at the same time I could add some head gasket sealant like blue devil or one of the the decent ones. That sound about right there Dan98 ??!

Do you think by me doing the cooling / radiator pressure test tomorrow it's going to be a waste of time you sound pretty knowledgeable about the Magnum heads??

You should test it but if it's in any cylinders then it's only pathway is trough crack in head and maybe the gasket you have two loaded cylinders next to each other in center of ether side with bad gasket.

Say my cheapest way out is to got the remanufactured heads right I'm looking at them now. So apparently manufactured heads a new gasket kit how much you think is going to be the labor after I buy that they're going to charge me to do that cuz I can do some of that brother but not all of it I ain't there yet you know I'm getting there but not yet??

If its cracked it probably gets worse or only leaks when it's hot and crack spreads open then after it's off leaks down in cylinder with the pressure you build running it cuzz engin compression fills cooling system that's y u only close cap half way once u get it going

Hey if I get it running by the way you just told me I've already just started draining the fluid out of it you don't think some top-of-the-line gasket sealer will buy me some time to save more money for heads and labor

There is so many of those engine out there 5.2 and 5.9 are both the same you could find some good used heads I'll bet. Then its gaskets you'll need 2 head gaskets and get a timing cover and pump gasket kit its cheaper and comes with all intake gaskets and bolts plus front main seal make sure u replace the belly pan gasket provided in the kit.

I just want to make sure I know all the coolant out of the engine do I take out the spark plugs and clean the heads and wipe them down they had me and been used yet I put him in Friday afternoon in the only used a gut is me trying to start it up less than a dozen times since it started Saturday morning but I know they've been fouled because of the fluid and plus when I pulled them out there were there were all black already on the Platinum tips so keep the cat halfway on the radiator and once the engine turns over go add a little bit of water or coolant then turn on the heater so I know when it's out of either 1 I just want to make sure brother

Hey Dan I really appreciate you helping me out man like I said my father was restoring this truck he put over 9 Grand into it I put over two Grand into it with a s*** ton of hours in labor but I love it he signed it over to me three days before he passed away from stage 4 cancer May 11th we were always into big Dodge trucks but thank you man seriously.

Hay, I'm real sorry about your Father, I've read this whole post, do you have a spark, put the OEM plugs back in it replace the wires, if any your heads are leaking you will have antifreeze in the oil, you said you changed it and there was none, antifreeze will come out first, you may have something going on with the electronic ignition, you need to verify you have a spark, you said the plugs were soaked probably with fuel.

 

[Dan98]

That should work maybe blowing plugs off with compress air if its handy
