How many miles on your DISA? if over 100k I would just get the repair kit, its wonderfully engineered.

I have 70k on my car so my DISA is in great shape, I only needed to buy the O-ring seal for it (G.A.S. sells the O-rings separately on the website!), and I figure when it gets up in mileage and with some more wear down the line, I will install the rest of the kit and probably another new seal when the time comes.

You'll be able to tell if you have a leak at the seal, bc when you unbolt the DISA if you can pull it out of the manifold rather easily, its bc of the seal. You'll also notice it will probably be flat as all hell too, which I noticed. Kind of a pain to scrape the old one out but gave me some time to clean the DISA too. $5 fix. If you need to do the whole repair kit bc of age/mileage, its simple to do and costs 80. I'm thinking about getting the reduced pressure coolant cap from him as well.
