Check the torque on those valley cover bolts while yer at it brah. Wouldn't even hurt to replace that gasket and the oil pressure sensor while you are that deep into it. Good job getting that bolt out ya lucky sumbish LOL.

X2 on the Permatex Ultra Black. I've never done the dam thing. I just smear a decent layer on the underside of the circular flaps before snapping down the knock sensor harness.

Also, X2 on replacing the valley cover gasket while you're right there. Maybe even the oil pressure sensor and/or cam position sensor, or at least the gasket on the cam position sensor.

I think this guy has it in this vid. He has a bad ass torque wrench. Check around the 21 min mark. I don't have sound a work.

Thanks the bolts were all good at 18lbs, the m6 x 1.0 x 70 fit perfect, she fired right up and no immediate codes drove it a couple miles, seems ok, time will tellIMG_20200826_152035.jpg IMG_20200826_160602.jpg IMG_20200826_161526.jpg
