Thanks again for the info. Ill try this one to "cut my teeth on" and when I grow up to bigger projects, Ill grow the tool selection as well. I do have one more last question tho:

How do valve spring pressures typically change? Are they dramatic or gradual over time? Im guessing probably both depending on whether a spring has failed or just getting weak over time. So I guess the real question is when do you call a spring bad? Is it a certain percentage pressure drop from the manufacturers spec or is it a fixed pressure drop (maybe 20psi) when you replace them? For my particular application I m running a solid roller at .700 lift.

Thanks again for the info

Drop

The spring pressures generally drop gradually, like maybe 20 lbs over time. If you check one and it's off dramatically, say 40lbs or more, then look for a broken spring. I've found broken springs twice just using an on head spring pressure checker. Yes they do work and do it often, beats dropping a valve! If your springs are a little off on pressure, you can just shim them up, depending on your installed height. But then you'll have to buy yet another tool!

Great thread.

I personally love maintence, if I am shown what to do, I will do it everytime. I am a perfectionist/neat freak and I am very paranoid about my motors. I do agree and think people are lazy, it is fun to work on ****. The lazy dudes should have money to replace ****, or not have it at all.

I too, have worked on s**t.....it stinks. And when I'm done with my s**t, I don't replace it, I just throw it away. But on a more positive note........When everybody is out to get you, paranoia is just "good thinking".

It has been said that: "youre only paranoid if they are not after you".

Some people can break a cannon ball, in a sand box, with their bare hands.

Preventive Maintenace

I have put together a preventive maintenance chart that I use. It has both a check list of things to do prior to racing till 24 hours following race day. I also have a PM chart that gives me specific PM tasks and when they should be done i.e. weekly, monthly etc.

I find that both the check list and PM chart keep me honest and prevent me from forgetting what needs to be done.

Charlie,

Any recommended basic maintence charts / schedules avaliable? By HP Level or something? Might be a nice thing to have on the trailer wall.

I made my own stuff. It depends on the type of racing you do etc. I used a simple Excel spreadsheet. :?

I don't have any charts or forms, however I do like Bill's idea and maybe he can post something for us.

I do believe that close visual inspection is very important and these engines will tell us a story if they are "happy" or not. We have just got to learn how to read the signs. Everybody knows you can read spark plugs, but also you can read valve seats, and bearings. You can look for signs of unusual wear on valve stem tips, cam lobes, piston tops, pins, chambers and a dozen other places in the engine that are indicators in regards to what's going on.

Hope this helps,

Charlie Evans

Noteworthy posts

This is a fantastic thread, thanks Paul for bringing it back up. I feel that maybe there should be a permanent spot on the forum for vital information that has been posted. One of the issues I have come across is that there is SOOO much great info being posted on here that you cant hardly read them all. Moreover posts such as this should be readily available to find for an awesome reference. Similar to a sticky perhaps or maybe even a sticky. Too often simple things are overlooked or just not known about that make the big difference between having a winning season or not. Even the longevity of the motor for street guys etc.

This is a great thread. I'm definitely going to invest in some tools. I was helping a guy with a pro-stock truck one weekend & he found a bent valve by using the spring tester. Luckily he had another bullet in the trailer, ready to go.
