Tough leak to spot....Id get a whiff once in awhile of coolant couldnt see any drips
Nothing out the tailpipe, wasnt using coolant, figured it had to be a head gasket on its way out
Within a min or two of parking it yesterday it dumped its contents on the street. Pouring water in results in water pouring out just as fast.
Looks like she puked a freeze plug behind the ds motor mount... plus a number of other maintenance items that somehow made it 32 yrs.
When it's all said and done, the most sensible route to take is to pull the motor and do all of em. If one goes, the others arent likely too far behind. And you have those two between the bell housing anyway. Replace the motor mounts while it's convenient. That's what I'd do anyway. Is what it is.
If it's just one make sure to remove all of the rusted freeze plug, use some sand paper wrapped around your finger to clean the blocks sealing surface. Push rubber plug in, tighten, fill with coolant normally and then pressure test.. as others have said.. the rest of them are probably not far behind.
In my experience core plugs typically rot out when coolant has been ran with water only etx. May be a good time to thoroughly flush the cooling system and pressure test
Had fresh green antifreeze in it...they are 32 yrs old though. Jim its a nightmare to get to..looks like the K brace and exh manfiold has to come off, then the motor mount.
How Id get another plug in (Hammering it) I dont fn know) Its tight as hell in there
Pulling an engine isnt in the cards right now due to a few reasons, for now I need it running
Explains why the system never seemed to have pressure or much when Id pull the cap. If the engine is out I know exactly what would happen...rebuild, front end, all the little stuff. 8k later-....lol
Not now
The rubber plugs just slide right in easily and then you just tighten the nut to expand it. Just have to hold it in place while you ratchet it because it'll spin until it starts to expand.
The rubber plug solution suggested by Bill Chase sounds the most viable and the easiest.
Those rubber plugs will last a long time. I had one in my Boat engine and It was there for at least 10 years.
I would take an ice pick and test the others. You don't want to poke holes in them but test their integrity. If the tip goes through then you know what to do.
Was it a steel freeze plug that rusted out or a brass one the corroded?
Maybe pick up a couple extra rubber plugs the sizes that will fit your freeze plugs.
Now go back out to your Corvette and caress it and tell it how much you love it. Positive vibes for your Corvette as it brings miles of smiles to you when working properly. This problem should not hold you down long.
Have an awesome Holiday with you, your family and your Corvette.
I cant see the plug its buried but seems to be where its coming from.
Going to guess they are original steel. Ill test the one by the oil filter thats not too hard to get to.
Ill try to put a plug in, if its impossible then maybe the expansion plug
I called it every name in the book and kicked it. Tough love.
Thanks
I had a leaking plug in a trans am that had a 350 in it. I used a rubber expansion plug in it for several years before I pulled the engine. Ran it hard several dozen passes at the 1/4 never had a problem.
Strong chance it could be that coolant exchange system which imo is useless, the location of the is right....
That could be bypassed pretty quick and car back on the road. Either way.....
Got a pissed tenant that got in the backyard and did further damage so sold it cheap this morning
