An engine valve normally needs to be removed from the head for a valve job, or to replace other parts related to its operation like the spring or valve guide. This is normally done when the engine has a poor seal from the valve/valve seat or oil consumption caused by the vavle guide.
A 4-cycle engine that has the intake and exhaust valves located in the cylinder head.
I recommend you get a service manual; the one the dealer techs use not Chilton, etc.. Ebay usually have these for the specific year. If you are going to do any work on your car you will need the service manual. The head can be removed after you remove the intake and exhaust manifolds, valve cover,head bolts (the 16v engine requires some of the rocker arms be removed to get to the head bolts). The service manual will give a step by step procedure.
After the cylinder head or block have been skimmed. For example. An engine has overheated and the cylinder head has been warped. The head is removed and milled so that the mating surface is flat again. The thickness of the oversized gasket will depend on the amount of material removed. If a thicker gasket wasn't used, the compression ratio may be raised or the pistons may come into contact with the valves
thats a big job irst you need to remove all accesories hanging off the head.then you need to remove inlet and exhaust manifold.you need to drain engine coolant.then remove head. once head is removed you can get at the valves.note when head is removed you will need to examine all other valves for seating and condition of valve guides. one would also try to figure the reason the valve burned out in the first place.also check all valve stem seals. so if all is good, replace bad valve, make sure it is seated properly bt doing a valve grind job.then put engine back together again.depending on what sort of engine it is, you may have to reset the timing.
The oil control valve is located on the upper left corner (if you are facing engine from the front ) of the cylinder head, close to the upper alternator mounting bracket. It has a two terminal wire connected to it, and is secured to the head by a single 10mm bolt.
Type your answer here... They are in the cylinder head.
IF there is no compression in one or more cylinder, you either have a bent valve, a burned valve or a bad head gasket. In any case, the head must be removed if you plan to repair the engine.
The cylinder head and valve gear.

A 4-cycle engine that has the intake and exhaust valves located in the cylinder head.
On a fully assembled engine, the intake and exhaust valves will not be visible. If the cylinder head is removed from the engine, the valves will then be visible. The intake valve faces are usually larger than those of the exhaust valves, and can be easily distinguished visually.
replace the engine ================== The engine would at least have to be removed, cylinder head removed, oil pan removed, and new bearings installed with rods. If you get that far, you may as well overhaul the engine with new rings, seals, bearings, valve job, resurface cylinder head etc.. Either that or yes, get another engine. Either way its a lot of work or even more money to have a shop do it. -Shaun
There are many gaskets on any car engine. If you are asking about head gaskets, they are between the cylinder head(s) and the engine block. The cylinder head is under the valve cover. --------------
Valve cover gasket holds oil from the valves from leaking off the top of the head . Head gasket is lower and holds cylinder pressure between the cylinder head and the engine block.
It's an over head valve engine ( pushrod ) it isn't an over head cam engine It has 1 exhaust valve and 1 intake valve per engine cylinder
The cylinder head must be removed. If you go to that much trouble, it would be best to resurface the head and do a valve job.
If the four cylinder engine is a Dual Over Head Cam design ( YES ) or it could be a V8 engine with 2 valves for each engine cylinder
