Q&A: How to remove cylinder head in car
How do you remove the cylinder head properly?
To remove the cylinder head, begin by disconnecting the battery and draining the coolant and oil. Remove the valve cover, intake and exhaust manifolds, and any hoses or wiring attached to the head. If the engine has a timing belt or timing chain, remove the timing cover and loosen the tensioner to remove the belt or chain. Use a breaker bar to loosen the cylinder head bolts in the recommended sequence to prevent warping. Once all head bolts are removed, carefully lift the head from the engine block. If the head is stuck, use the rope trick or gently break the seal with a pry bar. Inspect the combustion chamber and piston tops for damage before proceeding with a replacement cylinder head.
What are the steps to replace a cylinder head on a pushrod engine?
To replace a cylinder head on a pushrod engine, first remove the cylinder head by disconnecting the pushrods, rocker arms, and intake and exhaust manifolds. Remove the head bolts in the correct order and lift the head off the engine block. Clean the mating surfaces and inspect the bottom end for damage. Install the new head gasket, ensuring proper alignment. Place the new cylinder head onto the block and hold the cylinder head in place while tightening the head bolts in the recommended sequence. Reinstall the pushrods and rocker arms, adjusting valve clearance if needed. Refit the intake and exhaust manifolds, refill the coolant and oil, and start the engine to check for leaks.
How do you remove the timing belt when replacing the head?
To remove the timing belt when replacing the head, first set the engine to top dead center to maintain proper timing alignment. Remove the timing cover and loosen the tensioner to release belt tension. Carefully remove the belt, ensuring it does not slip off the crankshaft or camshaft gears unexpectedly. If the engine uses a timing chain instead of a belt, follow a similar process by removing the timing cover and chain tensioner. Once the belt or chain is removed, proceed with removing the cylinder head. When reassembling, install a new belt or chain to ensure reliable engine performance.
What are the differences between pushrod and overhead-cam engines when removing a head?
When removing a head from a pushrod engine, you need to remove the rocker arm assembly and pushrods before lifting the head. The camshaft remains inside the engine block, and valve timing is controlled by pushrods and rocker arms. In an overhead-cam engine, the camshaft is located in the head, so removing the cylinder head requires removing the timing belt or chain first. Overhead-cam engines also have camshaft bearings and valve springs that need to be checked during the removal process. Both engine types require careful alignment of the camshaft and crankshaft when reinstalling the head to avoid bent valves or timing issues.
What are the different types of cylinder heads and their functions?
Cylinder heads come in different types, including pushrod cylinder heads and overhead-cam cylinder heads. Pushrod cylinder heads are typically found in older car engines and use pushrods to operate the valves, with the camshaft located inside the engine block. Overhead-cam cylinder heads have the camshaft mounted on top of the head, reducing valve train complexity and improving performance. Some high-performance engines use dual overhead camshafts for better airflow and higher RPM potential. When selecting a replacement, it is important to consider the engine needs and ensure compatibility with the existing components.
What steps are involved in the process of removing a cylinder head?
The process of removing a cylinder head begins with draining the oil and coolant to prevent contamination. Remove the intake and exhaust manifolds, then disconnect hoses and electrical components. If working on a pushrod cylinder head, remove the rocker arms and pushrods before loosening the head nuts. For overhead-cam engines, remove the timing belt or chain before unbolting the head. Carefully lift the head off the engine block, making sure not to damage the surface. Once the head is removed, inspect for signs of a blown gasket or cracks before deciding whether to rebuild or replace it.
Why might an engine need to be rebuilt after a blown gasket?
A blown gasket can cause significant engine damage, requiring a complete rebuild. If coolant or oil has leaked into the cylinders, it can lead to loss of compression and internal corrosion. Overheating from a blown gasket can warp the cylinder head or even damage the engine block. In severe cases, rebuilding the whole engine is necessary to restore performance. Allied Motor Parts provides remanufactured heads and components for rebuilding, ensuring a proper fit. After a rebuild, checking the radiator and cooling system is essential to prevent further overheating issues.
How can the reverse order method help when reinstalling a cylinder head?
Using the reverse order method ensures that all parts are reinstalled correctly after removing a cylinder head. When reassembling, start by placing the head gasket and carefully setting the head back onto the engine block. Tighten the head nuts or bolts in the specified sequence to avoid warping. Reattach the intake and exhaust manifolds, reconnect hoses, and reinstall the valve cover gasket. If working on a pushrod engine, reinstall the pushrods and rocker arms before adjusting valve clearance. For overhead-cam engines, properly timing the belt or chain is crucial before starting the engine.
