You'll need to take the head gasket, line it up on the deck and mark the holes that don't line up. Measure them and purchase the right size freeze plugs. Best bet would be to find a shop to do it which is familiar with the job.

Theres only 2 machine shops in my town that I know of, one I would not touch, the other is very good but I doubt they have ever done anything custom like this

But yeah thats basically what I thought needed done too.

I'm compiling all this info though so any more details anyone has would be great

Might give English Racing a call. Looks like about a 2 hr drive from you. I'm sure they could handle it.

And I bought these from pepboys for like 10 bucks from their accessory isle. They fit pretty tight once the threads are crushed. I bang them in with the hammer about 1/8'' under the deck surface and then jb weld it flush with the block.

That's a good way to distort the deck surface. I can measure up the holes if you need me to, that way you can get the correct plugs.

Thanks, I actually finally found that pic on google and the thread talking about using those plugs.

I do not like that idea of pounding threaded plugs into the block either, will use freeze plugs and sealant and wanted machinist to do it before the surface.

I think they should be able to handle it, I really dont want to drive 2 hours away twice to get the block done.

Another option is to tap the holes and use threaded plugs with sleeve retainer. They won't be coming out then. I know I have heard other people using this process before.

Yes, sounds much better to tap and insert those threaded plugs.

What sealant would you guys recommend (I know not an rtv type) I saw somewhere the best stuff was some shellac, it had a funny name.

After you tap and use the threaded plugs make sure to have your deck resurfaced or you might have gasket issues.

I'm personally not doing it, machine shop will, the whole blocks getting honed and decked then the forged rod/pistons will be balanced and installed at the shop.

I'll be putting the head on, installing the engine and everything else ^_^

Just to post again and close this thread for all who need to search in future

oil holes to block off on the 2.4 block when putting a 2g eclipse turbo dohc cylinder head



Can use threaded steel plugs and tap holes or insert freeze plugs. What sealant to use? (I know not rtv)


1x1/2nch freeze plug
2x5/8s freeze plugs
2x11/16's freeze plugs


Finally found a pretty good page on the subject.

and another on the build, guy starts out saying how every other build is not very detailed and hazy then posts hardly any pics or documentation before he says cars running.

I will post the block I'll be building here when it comes back from machine shop after having this done

Wanted to post my pics of the oil block offs like I said I would.





In this pic you can see why they need to be blocked, the cylinder head does not cover them all the way. Look between intake ports on block.
