Pitting on block

[3p141592654]

Exactly. The pictures are too blurry to tell much. Plastigage those bearings (best done with the valves out, or at least the buckets out) and compare with the TSRM spec. You will know then what needs to be done.

If you have a lube problem the rear bearings will be in much worse shape since the feed is on #1.

My bad for not being clear on that, I was referring to the tolerances only in the TSRM . If you remove the material already built up, it will eat away at the cams and fill right back up, also making the clearances even larger than before.

So, head is back from the machine shop, everything looks good. It is nice and flat (according to them) and I am ready to put my supra back together tomorrow. I gotta borrow a straight edge tomorrow and double check to see if my block is flat.

-ARP Studs
-Stock Toyota head gasket
-machined head
-meticulously cleaned block w/ razor blades and 800grit
-Copper spray


Just a quick question on the copper spray, did I buy the right stuff?

If your head and block are flat, and you are using an OEM style composite gasket, yes, you bought the wrong stuff. You should have just bought a six pack of beer.

Permatex Brake quiet works nicely.

more importantly though, there is still slight pitting around the cylinder ring. I just want some extra insurance...

If you have pitting on the block near the combustion chamber, you will likely burn the gasket out at that point.
