Don't understand labor comment, it's two small bolts, you're taking out one big bolt (spark plug) and having to unhook and rehook the spark plug wire. As for expense it is not necessary to replace the gasket or crush washers every time you remove the cover. If it hasn't been off for a really long while, the gasket may get damaged in removal. If so, it was time to replace it anyway.lazyuniondriver wrote:.......and its associated labor and material expense when troubleshooting or timing an engine.
If it's fast and accurate why do so many have difficulty with it? My opinion is that most people are visual and holding your thumb over the spark plug hole is a little bit of the unknown. You can't see the piston at TDC. So they're not really sure it's there. Someone that has worked on lots of engines KNOWS it's there but the infrequent, backyard, shade tree, or whatever description mechanic has that little doubt in their mind that they got it right. SEEING the valves gives them the confidence. As I started this; that's why they have chocolate and vanilla. People have different opinions.lazyuniondriver wrote:Locating TDC on number one's compression stroke by removing the number one sparkplug is both fast and accurate with no additional expense.

It's easy & totally fool proof.

I stop at that point & align the timing mark.

I ALWAYS remove the #1 plug and crank till I feel compression and then line up the mark.
Removing the plug is a breeze and you insure that you are on a compression stroke.
