I'm just fixing up a few boost leaks around the bay and notice two injectors are leaking air. I've already got new seals on all four. Are there any further way to improved a better sealed surface?
Its been a long time since we had to retention head gaskets, but I still check them and always get a small turn on each the first time.
I check them whenever rocker cover is off, too easy with mitsi as you don't need to touch the cams.
