View Full Version : Injector seat replacement.

02-05-2015, 03:05 PM
So I broke down and bought aluminium seats for my small port manifold. I've take the seat out of my big port manifold and it took me forever and I'm wondering what's the quickest way to get the other ones out. Can I use heat at all? I've done the flathead and hammer technique and that just took so long. Thoughts?

Use a hex socket? I think they are 20mm I'm sure you could find a standard sized one since that is an uncommon size

I did that the first time and the seats just crumble because audi used the worlds best thread locker. Will heat help you think?

I had to use a torch, pick and wire brush to get mine out after I beat them with a screwdriver and hammer. Heat isn't as effective as you would think, they literally do not melt under a propane flame, get them glowing white hot and they just get kinda soft and re-solidify after 5 seconds.

Did you try to heat drum inside the runner to get behind the threads?

No I pointed it directly at the threads from the outside, the moment you remove the torch it begins solidifying, even if the rest of the manifold is piping hot. By the end I was holding the torch in one hand and a pick in the other because there was no other way.

Did the pic slice through the seat when it was hot?

I remember what I did now. I used a large easy out.

That must've been a massive ez-out, damn. And no the pick didn't really slice through it, the best I could do was stick it into the valley part of the threading and slowly unthread it out peice by peice. You gotta keep the heat on it because it re-glues itself to the aluminum the moment it solidifies.

Damn, guess I really lucked out when I replaced the seats on my polished manifold. All four spun out with no problem. I started to replace the seats on my brothers manifold though and the first one cracked to pieces (thankfully it was off the car.) Was able to use a small chisel and pick to get all the pieces out. After the trouble with the first one I skipped the other 3 and put it back together.

So I guess there's no easy way then.

Um, the easy out was kind of easy.

Where did you find an easy out that big?
