510again Posted February 15, 2011 Report Share Posted February 15, 2011 Hi need help. the breather hose for the case hooked up to the intake manifold is leaking drips of water on the exhaust manifold. blown head gasket? intake manifold cracked? need help. motor is a L16. thanks, james Quote Link to comment
datzenmike Posted February 16, 2011 Report Share Posted February 16, 2011 There might be a little moisture in that hose from 'sweat' forming inside the block on start up. The hose would have to be split for it to get out and it wouldn't be much to begin with. Check the hose for cracks and tight clamps. If it's dripping all the time it must be dripping down off the intake. So check the intake and the exhaust mounting bolts are snug. Does your intake have this small outlet hose on it? The small outlet just forward of the carb mounting studs. The finger is pointing to the water passage from the head into the intake. This is another leak point if the manifold bolts are not tight. The hose connected to it tends to be unnoticed and forgotten and they just rot away and leak. It could drip onto the heat shield under the intake and drip down on the exhaust. Quote Link to comment
510again Posted February 16, 2011 Author Report Share Posted February 16, 2011 i checked and the clamp was not tight. now after running the car it is smoking out the tailpipe(white smoke) like a blown head gasket, but the oil on the dipstick is clean and at normal level and the water in the radiator is clear and alittle green.

datzenmike Posted February 16, 2011 Report Share Posted February 16, 2011 A little 'steam like' condensation on start up is normal, but once warmed up goes away. If it has white (steam) all the time then likely the gasket is failing. Does the rad water go down? This could suddenly get very much worse as lead to a bad overheating and warping of the head. Or leave you stranded. Best to fix ASAP. Quote Link to comment
banzai510(hainz) Posted February 16, 2011 Report Share Posted February 16, 2011 tighten the intake bolts upper and lower. it could just be sucking in from the water passage holes that mike showed pitures of. Maybe try a new intake/exhaust gasket. maybe try retighten the head bolts. olddatsuns.com is your friend Quote Link to comment
