Mitsubishi MLS headgasket

[presterone]

I am about ready to use this gasket and I didn't send the block out to be decked. I resurfaced it with a wizzy wheel that has 3M disks that wont remove enough material but will clean it up close to mirror finish. Im sure someone has used this metal gasket without sending the block out... right? is this super sketchy?

Check the deck with a straight edge. Make sure its within spec. If so, use some copper spray on the head gasket. Good luck.

I've done it several times. As said above, make sure it's straight and use copper spray. You shouldn't have any issues with it.

Wizzy wheels on block deck? Bad idea.

I am running my Cometic MLS that way with 21 PSI and have not had any issues......I'm about 3000 miles on my rebuild!

Sounds like he used a rotary air tool with 3M sanding discs on the deck /ubbthreads/images/graemlins/uhh.gif.

I used a knife sharpening stone wrapped with 2000 grit wet and dry paper to very lightly lap my block.
Keep the surface wet with wd40 and put some grease into each bore to protect them.
Clean clean clean then clan again once you are done lapping.
Only lap in one direction at a time using full strokes. This helps to prevent low spots.
Mine was fine till I tried 37psi on std arps with a 6262!

I am kinda confused on why people just don't take it to a machine shop. It really isn't that expensive....

I didn't want to pull the engine out because I am lazy. my garage is crowded with projects and I didnt think it would be absolutely necessary


Thanks for the input everybody, I especially like the wd40 idea I don't know why I didn't think of that. I haven't used WD since I was 14 and rode a bmx bike everywhere.
