Well I haven't even started my new engine yet and I already have a small leak I think. I was filling my radiator up with coolant today and like 15 or 20 minutes later I noticed a few drops of coolant hitting the wood under my car. It's actually dripping from right above where the SLP y-pipe comes together. I'm not sure if this is the same as the stock y-pipe, but it's just below the blower box and heater hoses. The car was up on jackstands and the front end was slightly higher than the rear. I really don't know where it could have been leaking. I spilled some coolant into the battery tray area and I'm hoping some ran back and was dripping. The only other thoughts I have are the lower heater hose that connects to the metal heater hose or some type of block/head leak. Any other ideas?? Keep in mind the car hasn't been run yet at all.

Getting there.....383 with Super Ram, Bosch 24# SVO's, MSD, Edelbrock 58 mm TB, 700R4 tranny, Eibach springs, Koni 12 way adjustable shocks and struts, and more!! Now let's pray it runs when it's all back together!!!!

 

Well maybe its possible that its leaking from the intake. Where it bolts onto the heads and block. Check back there.

 

When my heater core went out, coolant was leaking through the body onto my ypipe and burning. Try bypassing the heater core and see if the problem is fixed, then you get to replace the core.

 

I don't see how it could be leaking from the intake because the car hasn't been started yet so there is probably no coolant back there at this time. As far as the heater core, I hope not. There really shouldn't be any coolant there yet either. I did turn the heater controls to on when I started filling up, but still no pressure in the system.

Going to fire it up for the first time next weekend as long as I get the speedo driven gear I broke!! 383 with Super Ram, Bosch 24# SVO's, MSD, Edelbrock 58 mm TB, 700R4 tranny, Eibach springs, Koni 12 way adjustable shocks and struts, and more!! Please pray that it runs when I try to start it....I've never done this before you know.

 

buy, rent, or borrow a cooling system tester and put some preasure on the system. see if it holds, see if it makes it leak any more.

I presume that you have already done this but I'll say it anyway, be sure all of your coolant clamps are tight and then do what ede says.

You have the cam break-in exercise to go through and you just don't need coolant leakage problems, unless very minor. There is enough going on at that time.

My lower radiator hose blew off, what a mess.
Then I fastened it back on and re-filled the radiator but apparently failed to re-fill the entire system and then a hi-temp crisis.

You just don't need that and as long as you already have a clue, fix it.

 

well i found out today that when your water pump seal goes that it drips coolant outta this little hole on the water pump.....well good luck and if it is that problem you have to get a new water pump

Yeah I'm back at school for the week but I'll definately get a pressure tester on the system before I try to start it. I just hope it's not a major leak because I put 4 gallons of 50/50 mix in today and I don't think my parents want it on their driveway during the course of the week.
