Lake Speed's Final Ride: Running His 1993 NASCAR Ford Thunderbird Wide Open (In Car Cameras)

What happens here

Lake Speed Sr. dons his helmet, straps into the car, and starts the engine. The car is driven off the trailer for the first track session of the day. Lake Speed Jr. observes the car's performance, noting its distinctive sound and 13:1 compression ratio. After the session, Lake Speed Sr. reports smelling oil, prompting Lake Speed Jr. to tighten a fitting in the engine bay and installing the check valve in the oil line. This modification routes oil directly to the valve springs and piston oilers, ensuring consistent oil flow above 35 PSI. They then prepare for a second session, with Lake Speed Sr. removing and replacing tires using an impact wrench.

Goal: Complete track sessions and implement initial mechanical solutions

Tools and materials

  • Helmet Simpson — Driver safety
  • Impact Wrench — Removing and installing lug nuts on tires
  • Socket Set — Tightening the oil fitting
  • Fresh Tires Goodyear Eagle — Replacement for track use

What they say

Hide

pan check of three or four bearings and they were all perfect and they you still see the down board gauge marks on them so it wasn't a bearing problem we went ahead and put a uh check valve on it where do you put that check valve in the system here I'll show you so where the oil feeds into the engine we have the two fittings to send oil to the B spring sprayers mhm and the one that went down to the oil pan where you put the bunk in right so what we did this time is now we have only one line that comes up here's that check valve so that only opens when the oil pressure is over 35 lb or something like that okay so once the oil pressure is over say 35 lbs it opens up then it comes up here and we got it teed so it can then run back down to run the Val to run the Piston Oilers and then it runs over here and runs the Val spring sprayers okay so we got one line so we also the leaks are the same but we're also kind of bleeding off less oil overall too suppos to have two ports coming off the oil pressure going in the engine we only have one so I guess that probably factors in too cuz it's it's got less places to all that instead of yeah I less leaks yeah yeah yeah it's going to get it's going to move more volume if it's got two dedicated lines instead of just one sharing it's not like we're running this thing 500 miles at 9,000 RPM the springs and the Pistons do need oil and we're giving them oil it's just not giving them anywhere near as much before so now our oil pressure we way overdid it that's the f h and I've noticed on a lot of the the Vintage Stock cars engines cuz I've been taking kind of visual notes on this stuff when I look at them most of them have the Piston Oiler or the the valve cover ports blocked off they don't even use them and I'm like well that makes sense the races are only like 30 minutes long so you probably don't even really need them but I I feel better back I know the B Springs like to be cool and pistons like to be cool especially these are Pistons that are really thin rings so we want to cool the Pistons we got thin rings in there so yeah you got higher margin for error if you do have an issue too might save you you got you're pulling a pin on a smaller grenade I guess but he's always beating my head risk versus reward yeah I'm taking this one all the way yeah I would do the same I think I'll even connect it on my engine too yeah I think you always take your notes the same way no cuz uh I had some here the last time so I started to go…
