Are you saying you have smoke coming out of the tail pipe ? Or is something dripping onto the exhaust pipe and burning ?
If the smoke is coming out of the tail pipe, is it blue, white, or black ?

SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

SOURCE: mazda mx5 smoking problem

Please provide more details for analysis like:
- what is the mileage on your car?
- is it smoking continously or only intermittently? How much smoke is it?
- what colour is the smoke? bluish or sooty?
- does it smoke when engine is cold or hot?
- is your car losing power?
- is your car consuming motor oil and at what rate?
- has the engine ever been overheated?
- is there an engine MIL ( malfunction indicator light ) code flashing on your dash? If it has, then you need to get the workshop to run a scan of the engine's computer to find out what the possible faults are.
- by the way, is your mx-5 fitted with a rotary engine or the common 4-stroke piston engine?

Quit smoking


The newer engines are very critical to torque specs. If they were not torqued properly, even the slightest, you can have what is occurring. The older vehicles had much higher torque settings and this was hardly ever a problem.

Why is my motor oil coming out my tail pipe?


Bad Piston,Bad rings,bad valve seals,Cracked cylinder head.cracked block. Don't forget now there is a lot of suction and compression going on in a motor. If any of the above are happening in an engine the suction will pass oil through a bad piston or rings or any of the above and cause Blue smoke and spit oil out the exaust along with blue smoke.

My 1985 corvette smokes out the exaust only when at idle and engine at running temperature.


most likely worn valve guides and probably dry cracked and fallen off valve stem seals you may get lucky with just replacing valve stem seals but may need guides installed in heads

White smoke coming from my tail pipe when I accelerate


You may have a blown piston ring, valve seals, valve guides, cracked head gasket or a cracked block, etc... It sounds major though for you to lose power suddenly and have all that smoke...
