Found a tiny bit of coolant pooled under the coolant crossover fittings on each head. Decided to tackle what I thought would be a quick fix today...
Took the crossover off, tightened down the braided line in the fittings and added thread tape and thread locker for good measure. Went to bolt the one side back down and the bolt stripped out the head :ayfkm:
So out comes the tap set. Try and tap it, that side already had a helicoil in it, so that got taken out. Ended up having to drill the fitting and the hole in the head bigger, then tap it for the new bolt. Got that side all done and cleaned up. Bolt it in, nice and snug with no issues. Great. Move over to the other side to bolt it down, same fuuuucking thing happens there. :rage:
So back to the drill press with the fitting, drilled the head, tapped it, and finally got it all back on and sealed up. Took a quick drive and didn't see any leaks, only time will tell though.
Fkn aluminum... I tell ya.
