That came on my gze block. Just pulled the clutch off today. TRD.
Compression test read high, too. Got 200-215 across all cylinders, although I'm questioning the validity of my gauge. My n/a had about the same compression (stock pistons, no much carbon buildup). But even then, that'd put compression at around 180 and this is a distributor gze block. Makes me almost tempted to pull the head, but don't think I will this time around. Gotta swap the pan, so I'll see if I see anything from the underside.
