I have taken the head off of my motor to replace the head gasket. The motor is out of the car at the moment also. I have got most of the big chunks of the old gasket off but there are some spots still on the block and a lot still on the head. I used a razor on most of the gasket and then a scotchbrite 3m pad. I cant not seem to get the rest of it off. And there is quite a bit off it on there. I have heard of the pertex (I believe thats how to spell it) gasket remover spray can stuff. But im wondering how good that stuff will work. Any input on this would be great. Thanks.

 

You should NEVER use Scotch-Brite or ANY abrasive material on either of the deck surfaces... You must realize - it's aluminum and when you use abrasives on it, it eats away the material and causes low spots. This leads to improper sealing - given a composite gasket can conform to these for the most part but it's not a good practice to develop.

You can use brake cleaner, gasket remover, even carb and choke cleaner... I would use brake cleaner that doesn't leave a residue. Due to the nature of the OEM gasket there will be staining on the surfaces - it's fine.

 

If it was terribly bad and u did alot of scratching at it then if it were me i would take it in to get milled just to be safe.

 

there is NO ifs and or buts! If the head gasket is being replaced its do to over heating im guessing!

The head Must be Machined MUSSSSTTT!!!

unless you want a head with wavy surface!

 

use a razor blade take your time and use brake cleaner to help!

NOTE: brake cleaner will evaporate very rapidly to dont spray it and expect it to soak in,

 

I just used the pads for the top layers of the head gasket. and then I started to use carb&choke cleaner and razors. But there are some spots still on it that wont come off. I will probably just end up taking it to a shop to get it done. I dont want to take any chances. Thanks for the help anyways.

 

the block is out anyways go get it decked and get the head worked too.

 

This is ture if the headgasket blew i wouldnt even think about putting it back together before have it checked out by a machine shop to make sure its not warped.

3M Ro-Loc Bristle Disc Pads

Yes, I use those... And they make specific ones for specific applications... The OP was talking about Stuff for prepping paint...

 

Yeah I have saw those tools. And the head gasket didnt blow. I just got a brand new head gasket for the motor in a trade, so I thought I would go ahead and put it on since the one that was on it has been on it for say 22 years. lol. Here's my two choices that I have, build a d16a6/z6 mini me and do it right, or just buy a b20 swap off a good honda motors website. Which do you guys think would be the best and the least cost.

 

depends on how you are going to build the d16 and what u plan for the b20
