Pre season DE Maintenance checklist

At the beginning of the season I routinely do the following. If I'm lucky I'll get 5 DE days running in intermediate group per season.
The car gets around 3k miles on the streets between track days and in the off season.

Feel free to add to the list.
  • Complete undercarriage inspection including but not limited to- All suspension and steering joints, connections, etc. Brake lines, any leaks, rattles, etc.
  • Oil & filter change
  • Fuel filter change
  • All fuel line connections
  • Air filter change
  • Trans fluid change
  • Brake fluid replace and bleed
  • CV joint bolt torques
  • Clean and re-pack front wheel bearings
  • Throttle linkage joints
  • Clutch cable joints
  • Pedal cluster joints
  • Clean or change spark plugs - re-gap, check timing
  • Electrical connections at lights, engine or other sources of gremlin entry

I usually leave well enough alone with the CIS, but since I'll be doing a partial engine drop to change my tensioner fitting seals and chain cover gaskets I'll be switching the intake runner rubber sleeves and intake gaskets. While that's all in bits I'll have a look see at the CIS plunger. If Santa comes early I'll pull injectors and have them cleaned and tested, and if I'm REALLY a good boy I may get that AFR gauge installed this year. Needless to say when mucking about with CIS I'll need to check pressures when it's all back together...
So, what did I miss?

I get my air gun with a long tip to blow all the rocks, cut ty raps, nuts, pennies and tire clag from under my pedal clusters. Amazing what ends up down there

All good ideas... except the paint chips.... you've clearly never seen my car up close...
Wheel inspection is a great idea.

I shudder to think what's lurking behind the bash plate under the front or behind pedals...

Also good time to check helmet, belts for wear, fire extinguisher, track bag with supplies, etc.

Timely thread as I'm off to track my car a few times this year.

Charles, saw in another thread you had a bung question regarding your LM-1. I've put mine on cylinders 4-6 just after it's 3 into 1. Ive heard this bank generally runs hotter due to oil cooler but I've never taken measurements.

I have been thinking about some long term inspections. For example are there any parts on the suspension that should be crack checked? What about front hubs? They are aluminum and mine are over 45 years old! What about front struts? Anything else?

When I tracked my car, I always had the valves adjusted at the beginning of every season. Probably overkill to have it done that often but in 8 years I never had a breakdown at the track and like every other superstition, you just don't mess with your preseason rituals.
The other thing that I used to do was go through my track bag and update the tools and supplies that I kept in it. Wire ties and electrical connectors, light bulbs, various fuses and relays, brakes pads, roll of duct tape, flash light... all kinds of crap. The way I looked at it, it was always better to have and not need than to need and not have. Plus I've made some really good friendships with guys because I had something they needed in order to finish their DE weekend.

Good list forming here. Thanks all.
I too am an over-preparer. I've made many people happy at the track by having an assortment of zip-ties to share. My tool kit is a little over the top.... I also have one of those divided plastic boxes with screws, nuts, bolts washers, spare spark plugs, bulbs, hose clamps, etc. So far haven't needed much of it (knocking on wood) but I've got it if I do.
I also decant brake fluid down into a squeeze bottle with a nozzle to make it easy to top up without wrestling with a funnel.

Yes indeed - I'm a list maker and user. Otherwise my head falls off.....

Yes

luck favors the prepared

Anonemous

Also, "cross threading is almost as good as lock tight"

Bon chance,

Chris
