Coolant pouring out from under car & heater stopped working due to low fluid level. Thought to be water pump but after further inspection turns out to be manifold intake gaskets.

starting loosing antifreeze in oil, overheated and white smoke started coming out of pipe. Replace upper intake gasket, problem resolved.

coolant leaking around on to manifold and possibly oil as well.

Intake Manifold gasket failed, developed a leak - as indicated by coolant pooling on manifold. This leak was very slow, and I had no driveability issues, but finally took care of it.
If this happens to you - have the mechanic check your oil pump as well, since the gasket material can degrade into your engine coolant and "sludge" up the pump, screens, etc. in your oil system...I am dealing with this right now.
wht smoke from exhaust will not stay running once i take foot off gas pedal oil ontop of engine by fuel injectors. antifreeze n oil oil drips on garage floor

125K miles, drivability ok but cross contamination of oil into coolant

After my previous oil change I randomly checked my oil level because I have been getting a hard knock when accelerating from a stop or a near stop. It was about two quarts low. So yesterday when I finally went and had my oil changed again, the mechanic told me my upper intake manifold was shot. Did'nt say anything about gaskets or lower intake manifold. Quoted me approximately five-hundred dollars.

had to replace manifold gaskets - TWICE. now at 197,000 miles and make sure you only put in 4.5 quarts when you change the oil seems to have worked the last 40,000 miles

Lower external intake manifold coolant leak

Found oil in coolant. Thought it was going to be head gaskets. Researched it on the web and many sites pointed to lower intake manifold gaskets. Did the job myself and as expected, gaskets were shot.
