Before starting the assembly, you must make sure that the head of the block is clean, regardless of whether this part was repaired in a car service or not.
1. If the head of the block was repaired in a car service, then measure the height of the spring in the installed state.
2. Install all valve train parts in reverse order.
3. When pressing on valve stem seals, remember that intake and exhaust valve caps are different.
4. Before assembly, grease the crackers to temporarily fix them.
