There is little to no smoke from the exhaust,. But today an awful lot of water came out the right side tailpipe after I started it hot (I had just driven it for about 15 minutes.). I ran the test in the radiator to check for combustion. IT was clean. Edelbrock heads are toqued at 55 lbs. Everyone I know keeps telling me I'm just paranoid. But is seems like something is going on. Im at a total loss here.
any help is appreciated.
thanks in advance
If you have a compressor , rig up a tool made from a old gutted spark plug to an air line ( or use the hose from a compression tester ) add air to the cyl and listen in the oil galley , intake and tailpipe . To test tailpipe and intake both valves need to be closed . I usually add 80 lbs , but start low . Dont forget to look in the rad and have its cap off .
