Ok I borrowed a pressure tester from a freind and He said I should put it on and pump it up to almost the "danger" zone (20+) and remove all of the spark plugs then leave it pumped up over night. In the morning cross the switch and see if any water shoots out of the sparkplug holes. He said thats the way he did it at the dealerships he has worked at and it works well. SO I did as he said ,and so far I haven`t heard any noises from anywhere and the guage is falling like 5 psi per hour. I guess in the morning I`ll go out and cross the switch like he said and see what happens. ------------------ http://maverickgrabber.iwarp.com

TURN IT ONE REVOLUTION BY HAND. You might find more problems if you use the starter. Trying to force a qt. of water out of a spark plug hole might blow a cylinder or break a rod. Rember the dealerships are in it for money.------------------ Glen 67 GT 390 65 Galaxie 500 XL 4 Speed It was not a Red Light they gave me a Slow Tree I WAS NOT LATE the Tree was Fast

It shouldn't leak at all! Try tightening all of the hose clamps, then re-test.------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00,'01,'02,&'03 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

Well I went out after 4 hours and it had leaked down to zero. I turned the engine over and had NO antifreeze come out of the cylinders (Feel better)I looked all around the cylinder heads and block with a flashlight...Nothing. I decided to pull the dipstick and see what the oil looked like...Perfect! So I retightened all of the hoseclamps and pumped it back up to 20 I`ll take a look again in the morning. Thanks for the tips guys. ------------------ http://maverickgrabber.iwarp.com [This message has been edited by MAV (edited 02-17-2003).]

Mav get some sleep!!!!! Mine did the same thing for 3 years.... Until I got rid of my high flow super trick cavitating waterpump.Is your radiator a crossflow or a downflow???? What you're seeing is most likely cavitation not a headgasket.... They blow big bubbles and foam.. Get rid of the glycol(coolant) until the motor seals. If your radiator is alum. The thing needs to be drained and flushed a couple to get rid of all the flux and chemical residue. Too much coolant isn't headgasket friendly. Use some waterpump lube and water. Good luck!!!

I ran the engine and let it warm up all the way with the checking tool installed,I let it get to 190 (fan was turned off) and was reving it Quickly to 4,000 rpm . I also held the engine at 3,000 for a few seconds. The result was NO increase in pressure on the Guage! This tells me I cant have a compression leak going into my cooling system and now I`m a happy camper indeed! Thanks for the help and suggestions on this guys! I think I`ll tweak on my carbs a little more (squirters),then take it up the road and let it rip some! ------------------ http://maverickgrabber.iwarp.com [This message has been edited by MAV (edited 02-20-2003).]

See how valuable a cooling system pressure tester can be???? ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00,'01,'02,&'03 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."
