Many years ago when I was working for Chrysler (for 42 years) we told techs to never use those wheels on aluminum surfaces. We didn't like techs to use them on cast iron. The suggestion was to use oven cleaner and a wooden scraper. I still use this method. It is litteraly fool proof with great results.

This seems like “was it the chicken or the egg” type of scenario. It would be fantastic to see a freshly milled aluminum head get whacked with a roloc pad AND roloc bristle (half and half the head) and then compare measurements.

I was a bit confused at first why someone would use anything much less scotch-brite on a milled head and then it dawned on me that some mechanics actually do this by hand which I wouldn't do on the biggest turd of a car unless the owner specifically asks for it. Otherwise scotch-brite is very useful only I use it by hand so I can't really overdo it especially on less critical surfaces. It's not a tool's fault if you're using it wrong.

So , when i was 11 yrs old 1977 i heard you could grind your head for higher compression... So , pulled head off my Briggs and took one swipe on the tool grinder. the looking at my work It was at that moment i realized just how screwed i was. I called my Uncle out of state who drag raced , sure wasnt gonna bother dad at work. I didnt even get past the i tried to grind the head... He just laughed and asked how i was gonna fix it? In despair I told him It was broke, and you cant . (I was 11) Dad got home from work (then bar), saw it, and flipped. Chewed me out royal, made me feel like a dork and handed me a dirty used Briggs cylinder head. Turns out...My uncle called him and they laughed, pops picked one up from the junkyard on the way home for like $2. Then dad ate dinner, told me i better put it together tonight! And hit the bar as usual till 11pm. Oblivious that i existed.

The flat rectangular stuff you buy in the kitchen section at the grocery store. It cleans up any other left over junk and brightens the head surface.

I bitched to Subaru headquarters and the replaced the gaskets again BUT I insisted on milling the heads (they all drop in the center of the head). 50,000 later no problems. MLS gaskets require a perfectly flat and fine surface finish. I port Japanese motorcycle heads....I won't touch a head unless I can valve job and mill the head. Same goes with cylinders.....they all need to be decked.

Scotchbrite is a material. Nothing wrong with Scotchbrite when used in certain applications. Those rotary tools some people like to use are the problem. Never use those on any machined surface, aluminum or cast iron. We get a lot of cylinder heads and blocks shipped to our shop that someone nearly 'ruined' with one of those rotary, spinning tools. I've joked with our Snap-on tools guy about giving one of those rotary tools to every garage around, because it will bring us a lot of work. lol

Nice try but go back and watch after the first cut. You'll see the spots where the headgasket's hylomar 'ring' is a higher spot than some other spots. When ANY abrasive media is used to clean up a surface, it's going to remove as much off the deposits as it will the clean metal around it. It will never make it flat, just pretty. Use a razor or a mill, that's it.

Having been in this industry for over 30 years, I have found that the best way to educate a customer is through a visual demonstration. I have yet to meet a customer ( whether a professional doing work for their own customer, or a diy client) who did not grasp the value of having the job done correctly the first time. If the head gasket is blown, we always recommend a pressure test to verify that the head is not cracked and also perform a warpage check ( especially with overhead cams!). Since our customers are already paying the book rate to R&R the head(s), the additional charge for the machine shop is money well spent. I am curious, if the head has to come back off due to seepage, do you charge them again, or do you warranty your work?

Worse is the bit you didn't mention. The same lazy mechanic will blow it off & slap it on, leading to lots of abrasive material going into the engine - it's impossible to get it all.

It's usually aluminum oxide, which is nearly as hard as diamond.

I have never seen a mechanic use scotch Brite on a head or block surface... I guess that makes me lucky? I've seen razor blades, gasket scrapers, putty knives and sand paper.. I have gotten away with using spray adhesive to glue sand paper to a cast iron surface plate and run the head over that. The thing is you need a surface bigger than the thing you're trying to flatten.. but using an indicator and some blue u can keep everything close enough to square and flat especially a pushrod head... Cams in the head does raise the stakes a bit but still doable.. I think a 2x4 with sand paper wrapped around it or a dull butter knife would have done better.

Hello Daniel. Thank you for this video. TL:DR How do you feel about using a brass wire cup brush on the deck surface? I found your video because I replace my head gasket on my VW and it leaked between oil and coolant, but not coolant to oil. I am about to replace the head gasket again with a new felpro gasket, as well as a new digital torque wrench. I used a brass wire cup brush on a battery drill on highest speed with varying pressure. I was still able to see the old gasket outline, but could not "feel" the things i could see.
@MrDanielSoliz Жыл бұрын
Be very careful with the wire brush, I’ve seen people be able to use it but most of the time it damages the surface. At this point I would pressure test the cylinder head and make sure it doesn’t have an internal leak. Then have the head surfaced or use some 320 grit wet and dry sandpaper and a piece of glass or flat surface to lap the surface. Hope this helps.
