Let’s get one thing out of the way right at the top.
Canuck walked his talk.
Not only did he spank us, he broke 1:30 driving the Camaro. He had a 1:29:6xx or something. Nobody was even close. Ceegar was second in his TransAm Mustang with a new personal best of 1:31:6xx, but that was two full seconds behind Canuck.
In this game, a two second gap is huge, even though a lap takes just over minute and a half. Or less than a minute and a half, if you’re Canuck. Let’s give credit where credit’s due. He was leading the pack.
That was on Friday, and the only cars that could have come close, the three big block Corvettes, were all broken. Beater busted his transmission in the morning qualifying session. His mechanic took the blame, he’d put it together. But had another one installed by dinner time and Beater will run on Saturday.
Cowboy came off the track early. There was a vibration he didn’t like, and it persisted in the pits when he revved the motor. It didn’t take long before Mule, his mechanic, had the valve covers off and found the problem. The rocker for the intake valve on the number 7 cylinder was lying on its side on the head casing. Both bolts holding it in place had come out and were lying by valves nearby.
“I torqued every one of those!” Mule said. A torque wrench was found and all the other bolts checked out. Mule went looking for an underlying problem.
Merlin was bent over my engine. In the morning session the motor backfired, lost power, gained a little power, backfired again. It wasn’t happy. After leaning out the carb and putting in a missing rivet for the exhaust pipe, Merlin said to run it and ignore the backfire. Jakester, my crew chief, even reminded me on pregrid that Merlin said to ignore the backfire.
So I did, I ran it as hard as I could until I just couldn’t stand it any more. She was still mostly willing, but I knew something was wrong. The backfires weren’t clearing up and if anything, were getting worse. She felt like she was walking in sand, not dancing light and eager as she usually does. I came off the track.
If you want to find fault with me for personifying a machine, go ahead. I was told more than once by a woman I dated for a while that my romantic point of view bordered on the delusional. She was convinced her cynicism contained far fewer illusions. I said reality, as she viewed it, was highly overrated.
Of course, she thought that was a perfect example of why she was right and I was wrong. I said something about a self-fulfilling fallacy and walked out the door.
Merlin found water in the distributor cap. After determining there was no water in the oil, and no oil in the water, and that the motor still had compression, he traced it to a pinhole leak in the gasket between the intake manifold and the head. He immediately took the blame.
He pulled the intake off and found a gasket either in my parts box or his (he usually orders two to have spares), cuts parts out of my old gasket to make a better seal, and put it all back together again.
While he was working, he overheard Mule and Cowboy talking about having no compression in the cylinder where the rocker had come off. Major damage. Cowboy was getting ready to pack up and go home.
I was saying something not too important when Merlin interrupted me and called over to Cowboy and Mule: “If the rocker is off you won’t have any compression. The valve can’t open to let air into the cylinder to be compressed.”
“Sheesh, he’s right. I never thought about that,” said Mule.
A little more back and forth, Merlin looked at the push rod they’d pulled and said they could turn it over and maybe drill out the oil port where it had gotten a little crushed.
“I’d run it,” he said. A little more discussion, and Merlin told Cowboy he’d go back to his shop after he was done with me and look for a push rod and some bolts to replace the ones that had backed out.
Cowboy was going to trailer up and drive back to Madras, Oregon, where he would pull a lesser engine out of one car to put in this car to run at Road America in two weeks. Instead, he’s racing tomorrow.
When we needed a timing light, Cowboy brought his over.
“I can lend you a timing light,” he told me, “since you lent me your mechanic.”
Merlin had been all over the paddock this day. Not only working on my car and looking at Cowboy’s, he’d come down to primarily support Ceegar. He’d fixed the jetting on a Lotus, the shift linkage on a Porsche, consulted a few others.
“It all pays off in the end,” he said.
Which was true. I’d shipped my car to Merlin in Seattle from MiddleofnowhereOregon because two years before I couldn’t get it running at the big race in Portland. It took Merlin five minutes to determine I’d been given the wrong carburetor gasket by the parts store when Shade Tree wanted to make a last minute change in the dark of my trailer when we both were in a hurry. Merlin had the right gasket somewhere, even though he wasn’t woring on big Chevy motors.
It’s not that Merlin doesn’t make mistakes. He’d failed to reset his timing light to zero a week before this race, and pretty much toasted a motor of a Mustang on the dyno. But what makes him Merlin is that last Saturday, a machine shop cleaned up the cylinders for him, parts arrived during the week and everything was back together and was ready when race day came around.
“You just take care of it,” Merlin told me. “I learned a long time ago, if you can step up for a customer and take care of things like that, you pretty much own them for life.”
Because he’s Merlin, he also pulled the plugs of my car. And that’s when we found what may have been the real problem, not that water in the distributor isn’t problem enough. Electrodes of three spark plugs on the driver’s side of the motor had been hammered nearly closed by the pistons beneath. All four of the plugs on the passenger side were fine.
“Did you take this over 7,000 rpm?” he asked me. I told him I didn’t think I did, even on my third to first shifts. So at about 8 p.m. as the sun slid behind tall Douglas Firs that surround Pacific Raceways, Merlin regapped the plugs, then indexed them, turning them just right so the pistons would leave them alone.
When we started her up, she was smoother than she’d been since I’d come to get her in Seattle.
“I could have caused the problem on the dyno, or it could have happened when you decelerated here at the track, ” he said. Pistons wobble, forces while racing are different, and we’d reduced a lot of clearances looking for more compression.
That’s what he was saying. But what I heard was a motor happier than it had been any time this weekend.
“Tomorrow we’ll tighten the half-shaft bolts,” Merlin said in the restaurant where I took him to dinner after we got done, since his wife had already made something at home. When called to tell her he was going to have a bite with me and then go to the shop to look for a pushrod for Cowboy, she said his dog Jed was pretty freaked out by the fireworks, since Merlin wasn’t home to provide reassurance.
