Folks, I have a question. I was going to install my TA adj oil pressure regulator tonight, but it doesn't seem to thread in properly. The original "bolt" threads in there just fine and seats perfectly as shown in this picture.
TA Adj oil pressure regulator part 2 Here are the two pieces side buy side, the thread depth and pitch seem the same to me...
TA Adj oil pressure regulator part 3 Yet, when I thread this thing in, I can only hand thread it in this far. I tried wrenching it a little, but I really afraid to damage my oil pump housing. Again, the normal "bolt" threads right in fine, so the threads aren't buggered up. Any ideas?
Paul, do the threads of the two males "lay" into one another if you place them side by side together? The picture actually makes one look a little different. I'm lacking sleep for working on the car and being here too much, so my eyes may be playing tricks...
. Ramin, I have not layed them one of top of the other...that is just sick!:grin: No...actually I did not try it, but visually the threads looked identical to me. The engine is at my brothers in Jersey, but I am headed back up there this weekend. Jim, I did try it without the spring and it only threaded in that same distance. In fact that picture with it in is without the spring. Any other ideas? I would really like to use this to help my oil pressure...
I don't know, judging by that picture it looks like a different thread. do you have a thread pitch gauge? That's one sure way to know for sure. :Smarty:
Paul, I'd be willing to bet that with a freshly turned crank you won't need the adjustable regulator. If your bearing clearances are where they should be you should have pleny of oil pressure. Did you check the clearances while assembling the bottom end?
This weekend Will be assembling this weekend Dave. The crank was cut and the rods resized, I told the machinist .002 ~ .0025 clearances. While I had ok oil pressure before the "problem", it wasn't stellar. Hopefully you are right and I won't need it. Kenny, I will check it with a thread pitch gauge this weekend. This is a TA part....shouldn't it be right? I am really puzzled.
Could one of the leading threads on the regulator be bunged up a little? One small nick in the thread will cause a problem like this.
. Dave Steele also suggested running a pipe thread die over it just to clean up the threads as well. Good advice. Thanks Dave and Adam (and everyone else). I can't wait to get this car back on the road! I finally have a stereo that should be able to hear while top down cruising. 1600 watts baby!:TU: Although the sound of the sweet 455 at full song is music enough most times.
