I have oil coming out of my tailpipe and where the exhaust connects into the head.

The engine was smoking very badly? Was any smoke coming out of the tailpipe? If not, either the exhaust manifold is broken or off the vehicle, or the exhaust pipe is broken, has a hole in it, or it is completely missing! Is it really loud?

You SAID the engine was smoking. But if you said that in error, then perhaps the exhaust system is okay, but oil is getting into the cylinders. Check for a PCV (positive crankcase ventilator) valve that may not be working right. Another thing that can make heavy smoke come out of tailpipes is a head gasket leak, with antifreeze getting into the cylinder chambers. How is the oil level and the coolant level? If there is that much smoke, it is advisable to not drive the vehicle for any reason except an emergency!

Coolant leaking on engine and burning

White smoke coming out of the exhaust on any gas powered vehicle is a sign that you have a blown head gasket allowing water from the cooling system to enter the cylinder, and when the piston comes up for combustion stroke and fires it turns the water to steam. This is also bad for allowing coolant to get in your oil, which anti-freeze in your oil will ruin the journals (Bearings) on the crankshaft (Major Engine Repair) costing several thousand dollars *NEW* !

There are at least three possible reasons for no psi in cyl No 4.
1. Burnt or damaged exhaust valve in that cylinder
FIX Remove head and replace faulty valve
2. Blown head gasket (water mixed with sump oil shows milky on dipstick and steam or water coming out of exhaust tailpipe, radiator water disappears )
FIX Remove head, grind flat and assemble with new gasket.
3. Broken piston rings, or cracked piston or burnt hole in piston.
FIX replace faulty parts.
Squirt some sump oil ( 2 or 3 spoonfuls ) through spark plug hole,
spin motor , and if compression PSI improves then it is rings or piston, if no PSI then it is faulty ex valve !!!

sorry but if you have white smoke coming out your exhaust, most likely you blew a head gasket. antifreeze is leaking into your exhaust and out the tailpipe. check your engine oil dipstick and see if the oil is a milky color. your local auto parts store sells a temp fix for it just ask for a head gasket sealer. good luck

has it been run hot lately?do you have water or coolant in your oil? pull the engine dipstick to see. do you have oil in the radiator? do you see coolant coming from the exhaust? these are all signs of blown head gasket. unexplained useage of coolant with no apparent signs of leakage usually means that coolants going trough the engine and out the exhaust system.smell bad when idleing in enclosed space? unexplained smoke coming from tailpipe when weathers warm? water residue dripping from tailpipe after the engines warm? i've given you most of the signs of a blown head gasket,which is what you requested, using alot of water with no sign of leakage. if no water in the oil,no oil in the water, then the leaks into the exhaust and out the tail pipe. you can do this, remove the ant-freeze from engine, then apply nanno technology[auto zone] water only added to engine. follow directions on 1quart bottle. this has worked for me several times.[for blown head gaskets that leak into exhaust] it's new technology that's new to the automotive industry. 1 quart costs $20.00 considering how much it costs to replace a blown head gasket that's only leaking into the exhaust sysytem,that's worth a gamble l to me. i've seen it work myself.

could be just head gasket and bad exhaust manifold gasket (coolant leaks past head gasket into exhaust port then leaks out of exhaust manifold gasket)
or it possible that head is cracked too
Only way to know for sure is to remove head and inspect it

If you are also losing coolant it is likely a blown exhaust gasket. The white smoke is a result of coolant leaking through the exhaust gasket and and being forced out your tailpipe. You can check to see if the head gasket is blown by removing your oil fill cap and checking the oil for a milky brown color. I hope this was helpful.

Typical symptoms of a blown headgasket may include: -bubbles of air coming up into your radiator (remove cap before starting) -leaking radiator -milkshake colored oil -overheating -rough running -coolant or oil running from head -spark plug(s) that have a green tint (if green coolant). -white colored or sweet smelling exhaust, white smoke of your tail pipe, or loosing coolant through your overflow

Either the cylinder head is cracked or, Is it possible that a stud had once been broken off in the hole(s) and when they were drilled out the drill went a bit to deep and punctured the cylinder head? That is about the only reason their would be oil coming out of the manifold stud holes as the holes are not connected internally to anything.
