How the EA82 manifold and carb swap unfolded...
Posted 06 October 2003 - 10:48 AM
When I first got it on, my disty died, so I replaced that, and now when I put my old EA81 manifold and carb back on, somehow, I have white exhaust. I don't think my heads are cracked, but you never know, and I can see water leaking slowly from the back of my engine when I look under the car.
Did I accidentally hook up some water stuff to my intake? I'm not driving it right now, and it's at Andrew's house. One way or another, we'll get it fixed, there is a spare engine I was going to purchase from him, so we'll be okay. got a spare engine for parts, it just needs new bearings, so we can use the intake and the heads if needed.

Did you just use the EA82 intake, or both the intake and carby? The hitachi carbs that were on the EA82's were feedback, and relied quite heavily on the computer (you can get em to run without the computer, but it takes some fiddling.)
When you take of the intake, no matter how much you try not too, you always get some coolant that goes into the heads. depending on how much got in there, you can end up blowing white for up to a week. SO the best advice was already given, watch your coolant level, and drive the &*#! out of it, see if it clears up, if not, then I would check gaskets.

I say, lop a bunch of form-a-gasket on there... and call it good.

I am not a big fan of silicon either, I seen it mess up gaskets rather effectively. use a real liquid gasket sealant as well as the papers. the water at the back sounds like you haven't connected up one of the little hoses on the manifold.
the poor idling sounds like a vacuum leak. I had to file off a little rise on the rhs of the manifold, coz it stopped the adaptor plate from sitting flush.
hope that helps, as you can see I had a few problems when I did it!

The problem with the EA82 manifold on an EA81 engine is that the disty doesn't allow much play, so you can't adjust timing acurately.
