Q: How to assemble a Cylinder Head on Buick Skylark?
A:
Check that all subassemblies of the valve mechanism are cleaned and dematted, and that the bare cylinder head is free of carbon and dirt itself and also reamed or ground for valves. Place a valve in the correct port and install the valve spring set of that cylinder comprising of the spring, damper, shield as well as the cap. Place the valve spring compressor of the assembly over the valve stem and compress it. It is worth to insert a new oil seal with the flat side downwards, and it must not be twisted. Next is to put the valve locks and release the compressor and ensure that the lock rests well on the upper part of the valve stem. Measure the installed height of the valve springs with a narrow, thin scale; measure from the top of the shim or spring seat to the top of the valve spring or spring shield. If needed, place up to 1/16 th inch thick shim under the valve spring to build the required thickness; nevertheless, do not shim down to a height that is thinner than the specified minimum length of the spring; if this happens, get a new spring. Last of all, inspect each of the twenty stems for oil leaks using a vacuum test simply because if the seal is installed correctly, it should not cause any vacuum leakage.
