I didn't open the cylinder head because I knew exactly what was wrong. I opened it precisely because I didn't know.
In a 1989 car with a racing past and a mechanical history I didn't know, just checking that the engine ran wasn't enough.
If I wanted to rebuild it properly, I first had to know what state it was really in.
When I stripped the cylinder head, I found the intake and exhaust ports caked with grime and the valve stem seals hardened after years of use.
I cleaned the ports, replaced the seals, changed the head gasket and inspected the whole assembly. But the part that demanded the most patience and precision was recutting the valve seats.
It's one of those jobs that doesn't look very spectacular from the outside. Each valve has to be worked carefully, with no rush, so they all seat properly again.
This is exactly where I learned the most.
Opening the engine let me stop guessing. Now I don't just know there are new parts: I know what was there, what I fixed and how it went back together.
To me, this is one of the differences between repairing and restoring.
Repairing can be fixing a breakdown. Restoring is also getting ahead of problems and truly knowing what you're rebuilding.
Because restoring a car isn't just swapping parts. It's understanding it until it becomes yours again.
