Cars – don’t we just love to hate them? That definitely sums up Scotty’s feelings in this week’s episode of Carnage, as Supermang’s new stroker V6 puts up one hell of a fight.

The first issue was a decent coolant leak. We’ve all known the frustration of spending hours installing an engine, only for it to start pissing out water from somewhere. The 4.2-litre L67 did just that to Scotty, but sadly, that was only the beginning.

While diagnosing the leak with the car running, Scotty noticed the L67’s valvetrain was pretty noisy. Sure, it’s a freshly assembled motor, but the noises weren’t going away with time and more starts, so the signs were pointing to a lack of oil pressure.

Scotty had done his due diligence before the first start – priming the engine with oil, filling the oil filter, and so on. Even so, after connecting an oil pressure gauge in place of the factory oil pressure switch, he confirmed that the engine did in fact have zero oil pressure.

With no cause immediately obvious with the engine in the car, Scotty had no choice but to pull the stroker out again. After much searching, he finally discovered that the oil pressure relief valve and spring had been put in the wrong way on the front engine cover. So, that’s where the oil pressure went!

With the culprit found, it was then time to see if it had caused any damage. We’d unknowingly run the V6 several times without oil pressure, so we were bloody nervous. Luckily, the new bearings still looked straight out of the packet, so we dodged a massive bullet there.

In an upcoming episode, you’ll see the engine back in and hopefully making oil pressure, and then it’ll be ready for the dyno. In the meantime, if you’re in Melbourne this weekend, come say g’day to us and Scotty at MotorEx! You can buy tickets here.
