Is .002" enough to worry about one way or another? Can you take .008 off the top of the pistons if you can't do it with head gaskets? It "might" have lived at that point, but this little guy will push 28#'s of boost. That's quite a bit when you consider what's actually holding the head down. As far as the pistons go, with the way they're designed (crowned)it would me near impossible to cut them down. machine shop owner and engine builder

Them are just as bad. they are harder than you think. I have seem lot of bad things from both. everyone ask me why I keep all them wore out ones in my box. a little comment sense go's a long way when using these things . most of the new stuff I use scottbite pads by hand. they come in 8x8 sheets and I cut them in to 4 pieces.

Yes if you hold a disc in one spot long enough it's not going to be flat. Small diameter discs and worn discs make the problem worse. I never had an intake or head gasket comeback. As a flat rate tech it always pays worse when doing the the job a second time for free. If they didn't work I would have never used them. That being said, inexperienced hands can do a lot of damage in a hurry. Now a blue printed performance engine, different story. Not even the same animal. Doug

In this one you can see more clearly where the Roloc disc dug in a little harder. Obviously the blue spots are the LOW spots. IMO, The pics arent proving your point. I see very large Uniform Diameter impression marks of different depths in the first two pics. Evidence of a bad hand rolex disc clean up would be less uniform and sporatic. In your First pic, the Cylinder tops are untouched by your first shave but the deck clearly shows a wide diameter pattern impression. On the Second cut the "one cylinder" shows the same pattern of the wide diameter cutting impression that the Deck shows on the First cut. Last edited by Sport440; 10/08/13 01:48 AM.

Everything you use that is compressible (like sandpaper or similar) will try to round off corners and although we are talking about margins, that could be critical. Thanks for sharing this!!

That being said if he removed .060 of iron with a rotoloc he used more than a couple and certainly more than what was needed to remove a gasket. Maybe he was trying to remove the indent from the fire ring? A monkey can destroy anything by not giving a crud. I see nothing wrong with using the correct abrasive or "finger" disc sapringly to clean off residue, being careful to keep the debris out of the bores and coolant jacket. That is what the directions say to do... Me and thousands of others have been using them since they came out with no results like that when care is taken to do it right. Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

He didn't remove .060, more like .006-.007. I've been using abrasive discs for decades, the point here is that the deck of a block or head is not a good place to use them IMO.

I work for Cummins now (not wrenching now though), and they don't want us using them either, but they approve of the scotchbrite pads----which will put just as much garbage in the engine, but is easier on the deck surfaces doing it by hand vs a roloc on a die grinder. We have issues with protruding / dropped liners, so being carful on these engines is important. The plastic bristle ones are approved though, but again, material gets flung all over, and yes, they can do damage to the surface too, albeit less IMO. I am guilty of using them on decks, have for years, but I try very hard to keep it moving and not stay in one spot (kinda like leaving a belt sand in one spot on a piece of wood). Anyways, maybe its time to look at changing my methods when concerning deck surfaces. Outcast Dodge guy.
