OK guys. This is not a Camaro we are working on, but since I owned a 72RallySport at one time and I know all Camaro fans are diehard Chevrolet fans, I thought you might help me.
I think this problem could be seen in any V-6 or V-8 engine.
I have a 1998 half ton Chevrolet pickup with a V-6. Automatic transmission, A/C and other normal creature comforts.
A week ago I noticed a water leak on the garage floor after I moved the truck outside.
The truck had been sitting from Friday evening until Sunday afternoon in the same spot without being started.
The leak was originating from between the block deck and the cylinder head at the number 5 cylinder. There was a very fresh water trail that had run from this area all the way down the block to the side of the oilpan and then of course onto the ground. About 2 tablespoons full.
I looked all over the engine very carefully suspecting a leaking hose but of course their are no cooling hoses or fittings this far back on the engine. All are up front like a typical V-8 Chevy.
I decided to carefully drive the truck the next day for a short trip to see if the leak continued. No leak after the engine warmed up.Infact the leak did not show up the next day. Continued to make daily observations with short drives and could not recreate the leak.
Sorry this is so long but it is getting to the point.
This past Friday the truck was driven and then parked until this Sunday. Guess what I found Sunday evening. Thats right! The leak had reocurred in the same place as before. About as much water again 2 tablespoon fulls and a fresh trail down the side of the block originating around the number 5 cylinder. No water trail on the head or above it.
One mechanic I have spoke with suggest a cracked block. Stateing that the block has to cool down for 48 hours before the crack emerges. I can maybe see this. I thought 24 hours would have been long enough for this to show up. Maybe not.
I took the truck to the Chevrolet dealership today for this problem since the truck is still under warranty. 31,000 miles in 2 years and 10 months is not much use. This truck has been well taken care of and not abused when driven.
Would a pressure test of the cooling system show a possible crack in this situation since the problem seems to only occur after 48 hours of not being used. And if so would the same test be accurate in as little as 24 hours.
Can anyone shed any light on this problem? Have you heard or seen such a problem before even with a V-8, or could this maybe be just a bad head gasket.
Again if you made it this far I greatly appreciate your time and patience and look forward to some positive suggestions so that I will know what would be the proper procedure for fixing this.
Long Live Camaros and God Bless all Chevrolet fans.
