Hah! Finally found it on an engine diagram!
It?s a ?Holder Assembly Oil Control valve?.
Apparently it has something to do with the camshaft.
Does anyone have any experience with these leaking?
Do I just replace the gasket, or both the gasket and the assembly?
Recently my STi when I?m trying to do a slower, controlled acceleration (like in a construction zone) has been doing a whiplash inducing front to back dance at low rpms (say between 1.5k and 2.5k). I can?t tell if it?s some type of hesitation due to fuel issues, or a drivetrain issue. It smooths...
Check with companies like Scosche or Metra Electronics. They have wiring harnesses that connect to the factory wiring, but some also make harnesses that connect to the back of the deck, so if you had both harnesses you could use that as a bridge with the LOC wired in the middle.
Don?t know of...
So I put everything back together and warmed the engine up, then spent about an hour pulling the plugs back out. When I tested the engine was still warm to the touch. That being said, here's what I got:
Maybe I can blame the elevation... *gulp* So these seem...
I am currently trying to do a compression test on my STi, and I'm not sure what is wrong.
It took me over three hours to pull three spark plugs out last night, and I got the fourth one out this morning (stupid tiny work space!). Because of that, the car isn't warm. I have all of the spark...
Hmm, this pic doesn't include the problem nuts. On the left side there is the piece labeled 16. In the gap above the label t8 is where the drivetrain goes. On the pic, on each side of said gap, are the holes where the problem bolts are.
It's called "Liquid Wrench". I've used it multiple times on these nuts to no avail, but it's worked on others.
As for the cheater bar, I've done that as well. I have a 24" breaker bar, and I added a 36" cheater bar to that. Unfortunately being up on jack stands I don't have much room to work...
I've been upgrading the bushings on my rear drivetrain and differential, and I cannot seem to break free the nuts holding the front of the diff in place!
The part I'm referring to is the rear differential, front mounting point. It connects to the bottom of the diff with two 17mm nuts (those I...
