1.) Check spark plugs - This is the first thing I tell people to do if they think they've got a problem. Pull all your plugs out and take a look - it will be obvious if one cylinder is having a problem.

2.) Do a leak-down test - If you think your engine is down on horsepower a leak-down test may help you locate the problem. It will find blown head gaskets; broken or stuck valves; and bent or burned valves. If you're missing a lot of power you'll need to see over 20% leakage.

3.) Inspect oil filter - Same as your weekly maintenance. If bearing problems are caught early by checking the filter, you may save thousand of dollars in repairs. A spun bearing will give little warning - if you think there is a problem, check the filter (it will be obvious).

4.) Check drain plug - If you're at the track and don't have a way to inspect your filter, the next best thing to do is check the magnetic drain plug (You do have one, right?).

5.) Inspect valvetrain - Check the valve spring pressure; valve lash; look for broken coils on inner or outer springs; broken rocker arms; missing lash caps or; broken or bent pushrods.
