Road America Spring Vintage Weekend 2012

Spring Vintage Weekend 2012
Road America in May is known for changeable weather. Many avoid the spring races because it can be raining, sleeting or snowing. They missed the boat this year because if there was a more perfect weekend anywhere it would be hard to find. Deep blue skies and warm – Cool Shirt warm -- temps.
P and B Motorsports was blessed, cursed, and blessed. The first blessing was Duane Matejka’s presence. The curse was the loss of freeze plugs from the new motor, and the blessings returned with our ability to patch things up and have a good finish.

Car builder Duane and Race Engineer David Farrington flew in early for the Lamers Track Day that took place on Wednesday before Spring Vintage Weekend. Transportation Coordinator Sam Seward graciously ran these two to P&B Motorsports headquarters from the Milwaukee airport. Lamers annual invitational charity event– Denny Lamers calls it “a golf outing for gearheads” -- attracts over 200 hot shoes in race cars and [mostly] high performance street cars. Several non-profit organizations benefit, among them Wounded Warriors and a program that encourages responsible driving by youth as they start their on-the-road experiences. The health care provider that puts on the driving program flew in a life-flight helicopter for the event. You can read about the track day at
ThedaStar LifeFlight Chopper. I never want to be in this baby in the prone position.
We had installed the right seat and bought an intercom system so Duane could ride with me, but that was not meant to be. At 8 a.m. I headed out on the track to break in the new motor gently, only to have the number 4 freeze plug come out after 1.5 laps. We attempted an at-track fix but the head gasket was also blown so the opportunity for Duane to spend time coaching was lost. The car went home to the shop for a more extensive fix.

As Yogi Berra said, “This is like déjà vu all over again.” I met Duane in 1986 at a Washington, DC area Volvo meet when I was doing a gymkhana with my Amazon and I blew a freeze plug at high RPMs. Duane fixed it!  Who would have thought that 36 years later he would be doing the same thing?
Friday found us back at the track ready to go. Our first qualifying run was a good one. Water temp held at 160, everything tight. Then in the afternoon’s 2nd qualifying session we made it only two laps before the #2 freeze plug came out and I saw the back of the tow truck. Now we got serious, pulling the carbs and intake manifold back, removed the headers, whacked the plugs in and put some JB weld over the top.
But the gremlins were not done with us. When we got to the grid Saturday morning Duane saw a small stream of water coming from one of the plugs we had replaced, so that qualifying session was aborted. Time for the high-tech solution – Barr’s Stop Leak. And that did the trick.
Saturday’s Qualifying Race put us into the 7th row for Sunday’s Feature, with some significantly faster cars in Vintage C Production in front and a lot of slower cars in that and other classes behind. Once again this year Bob Wagner in his 3 liter Austin Healy 3000 was in front of us, running about 5 seconds faster. Bob placed first and we took a second in Vintage D Production. The only other Volvo at the track was David Hueppchen’s No. 72 fuel injected ‘72E.  David ran the 200 mile endure on Friday and then had a bunch of issues after that, including dropping No. 3 and 4 cylinders, so he was parked after the Enduro. During that event his alternator fan disintegrated, producing a pretty spectacular dimple in his hood – looks like someone used the back side for target practice from 500 yards with a high powered rifle!

Despite the freeze plug issues that plagued us all weekend this Spring Vintage could be classified as just about the most perfect weekend we have experienced because of the outstanding weather, but more importantly the number of friends who were with us. Doug Senk cruised over from Mukwonago in his tricked out 1800 to join the P&B crew. Doug is a regular with Jeff Babcock’s 122 team but Jeff did not run the weekend so we benefited from Doug’s “what can I do to help?” attitude.
 On Friday Chris Clemmer (‘73ES) picked up Skywest Airlines pilot (and Bjurholm, Sweden resident – really!) Jan Efverlund at O’Hare and came up to Road America.

Milwaukeean Jim Slapikes is always at the track with his ’69 1800S. John Tuteur was present with his gorgeous steel grey ‘71E. At times it looked like a meet of the Lake Michigan Chapter of Volvo Sports America.

Jeff Babcock came up from northern Illinois in his 740 Turbo wagon on Saturday, and longtime friend Phil Koller from Appleton, WI spent the weekend with us, taking many great photos. Joe Brabender (Amazon #123) and his son came up from Stoughton bearing Mobil 1-related gifts. Add Duane and the rest of the regular crew and we had one heck of a party, pretty much continuously. Chief Torque Wrencher Joy Perry was able to hand off many of her duties to Duane and concentrate on keeping everyone watered and fed. Crew Chief Dave Buettner made a comment on Monday that he hoped that I had thanked Joy profusely because she “worker her [butt] off.”

Race Engineer David Farrington spent the weekend being teased about his proclivity for conversation with anyone within earshot and trying to get a video synchronizer to work. (He’s still working on that with the supplier.)

Pam Buettner was the only one without a hot pit wristband, but she is among the most gracious and pleasant people to be around, and never lets me forget that I would look better with shorter hair.

Having a lot of people to watch also allowed me to get feedback and learn better track position at various turns. We spent one evening in the motor home reviewing video and discussing lines. Duane’s presence was invaluable from a multitude of aspects, not to mention that he is just about one of the nicest guys you would ever want to be around.

We have a month-long break from racing, but are headed to St. Louis, MO, with both the race car and ES for the national meet of Volvo Club of America next week. Here are some more photos of Spring Vintage for your enjoyment. Movies will be posted when we have the video integration sorted out. Ugh!

Winter Work 3- The Finale

Learning experiences abound the first time one does anything, right?
Even with a transmission jack getting the M47 in alone was not a piece of cake. We had removed the tranny mated to the motor in the fall, so now I had to disconnect the drive shaft at the rear, remove the center support bearing, remove the Sellholm shift lever from the linkage and wedge the linkage out of the way. Even at that the angle just seemed to never come out quite right. But eventually it slid in with the appropriate amount of cussing and sweating, and I bolted her up.
Installed the clutch slave cylinder and called the Chief Torque Wrencher over to help me bleed it. Herein was the start of a new set of issues. Blew the seal out of the slave cylinder. Moreover, the clutch fork looked a little like it has been twisted backwards.  Now what did that slave come off of???? Duane’s recollection was that a 740 had been the donor.

Slave cylinder. “In and Out” barely describes it.

Bent clutch fork

Northeastern Wisconsin is not a hotbed of Volvodom. And if it’s not 'in the computer' of the local Volvo dealer (i.e. anything not older than about 5 years) it might as well not exist. I headed for Swedespeed Forums, posting photos and asking about sourcing of things from a “newer” (for me) old Volvo. Turns out that these units were used for many models over many years, starting with some 240s extending all the way up to the 800 series. Thank you George Dill.
With that information in hand I was able to source a new fork from Swedish Auto Parts for less that he prices of a gold one that the Volvo dealer could get if I provided the part number. Got a new slave cylinder and throw out bearing too right away, “just in case.” And Advance Auto Parts was able to get a slave cylinder kit that included the unneeded rod boot and very necessary seal. Made in Germany, of course.

New clutch fork and throw out bearing

The Crew Chief finally left the land of perpetual sunshine and hanging chads (I don’t hold much of a grudge … well, maybe I do) and got back to residential reality  just about the time I was ready to put the new seals in. I had put two quarts of fresh 85W-140 hydraulic fluid in the shiny dry transmission, only to find a small puddle on the floor the next morning. Crew Chief was convinced that this was likely to contaminate the new clutch if not fixed so out that son-of-a-gun comes. The new seal between the transmission and bell housing was leaking.
As it turns out there is no continuity that would allow the fluid to reach the clutch, but I pulled things apart and sealed it up with a gasket sealer anyway. Should keep the underside of the car a bit cleaner at a minimum.  
OK, several days later we are all set. New slave cylinder in, bled, and adjusted. Pump, pump, pump on the pedal and bang, out goes the seal again. And that new clutch fork?  Bent.
Well, it does not take a genius to figure out that somethin’ ain’t right. Like why is the throw out bearing jamming into the clutch disc hub? Hey, I’m beginning to feel like Andy Granetelli when it comes to taking this transmission out. (If you don’t know Andy Granatelli, do a search, you’re too young.)
I could make this long story even longer but the shorter of it is that Pegasus Racing sold me the wrong pressure plate. The original and new one look almost identical, but remember, close only counts in horseshoes and hand grenades. To their credit, Pegasus owned up after a call to Tilton, but that still left me with putting the old pressure plate back in while I wait for a new one.

This is NOT the way you want the diaphragm fingers to be pointing when everything is bolted up!

If there is a silver lining to this frustration it’s that I now have every darn measurement possible on clutch disc, flywheel floater plate, pressure plate, slave cylinder bore and seals, part numbers and a new set of sources for the next time.
Learning experiences abound the first time one does anything, right?
Oh and that new throw out bearing? Not a race piece. Anyone need a new one for their street car?

We’re as ready as we can be. New motor is tuned and benchmarks established for compression and leak down, all EGTs actually work, clutch seems to behave as designed, alignment done, fuel pump inertial cut off hooked up, and paint chips filled. Most of this is thanks o Crew Chief Dave Buettner. Dave’s a really good guy, but just maybe he really wants his garage back. J
In three days we head for Road America for a track day sponsored by a bunch of business friends who are equally crazy into racing. A day off (???) and then we head back there for Spring Vintage Weekend. Duane Matejka will be with is for the week to offer some coaching. Race Engineer David Farrington flies into Milwaukee at the same time. Transportation Logistics Head Sam Seward will pick them up and deliver them to P and B Motorsports home base. Should be fun.
Stay tuned. We’ll hopefully have new video and a Spring Vintage Weekend 2012 report for you in about 10 days, the forces of nature willing.
Let the season begin!
