Animal Posted February 21, 2007 Share Posted February 21, 2007 Well, I finally started putting the replacement parts on I've had laying around; complete new clutch assembly, including flywheel, rear main seal (reason for new clutch), Pacesetter headers (I know I should have bought Thorelys, but had these before I knew better) with added flanges to crossover pipe and oil filter relocation kit. Starting the front and rear steering and suspension parts tomorrow, but ... I installed the new exhaust studs and (here's where it gets bad) the one on the rear passenger side stripped in the head when tightening the header flange. Dreading the prospect of the heli-coil route, we seem to have fixed the problem. Now I have a question. I have looked in all the books, searched high and low and can not find the answer so ... how are the studs supposed to go? There are short and long thread ends. The ones I removed were short thread in the heads, but measuring, we discovered the threads in the head are long enough for the long end and considering that this is into aluminum, it would seem best to have as much thread as possible. However, that is not how the old ones were installed, so I am wondering if they were not installed correctly. Putting the long thread end in the head, with a little liquid metal for good measure, held well enough to tighten the header flange, but I am left wondering if the other 11 are installed correctly and if so, what logic, if any, is behind using fewer threads into aluminum heads?

SteeevO Posted February 21, 2007 Share Posted February 21, 2007 i don't remember for sure but i think the short end does go in the head... my reason for this is because if you put the short side out the nut may bottom out on the non-threaded portion of the bolt before tightening... but maybe someone else can chime in to verfiy or correct me.

Pavelow Leaks Posted February 21, 2007 Share Posted February 21, 2007 on most motors the short side goes into the head, but I don't know for sure on the pathy's Link to comment Share on other sites More sharing options...
Animal Posted February 21, 2007 Author Share Posted February 21, 2007 Thanks all for the quick replies. This is what I thought (and am use to), but normally the heads are not drilled and threaded deep enough for the longer threads. Other engines I have worked on have a bigger difference. This is why I started to question this in the first place. Since the non-threaded portion is the same depth regardless, they will tighten up either way. I guess I'll leave them as is and be satisfied. Link to comment Share on other sites More sharing options...
Simon Posted February 21, 2007 Share Posted February 21, 2007 I figure if they fit in the heads the way you put them, and you were able to tighten the flange down, you have nothing to worry about, and your logic of having more threads in the aluminum head is valid to me. I'd say whether or not it was SUPPOSED to be done that way, yours may be the better way. Link to comment Share on other sites More sharing options...
k9sar Posted February 21, 2007 Share Posted February 21, 2007 I recently pulled the studs from my old heads. Short side in and log side to go through manifold and accept nut. but... whatever fits. Link to comment Share on other sites More sharing options...
EvilErnie95 Posted February 21, 2007 Share Posted February 21, 2007 With the Pacesetter headers do you still need to relocate the oil filter? And how muc better are Thrleys VS the PAcesetters? Good luck with your project! Link to comment Share on other sites More sharing options...
Animal Posted February 21, 2007 Author Share Posted February 21, 2007 With the Pacesetter headers do you still need to relocate the oil filter? And how muc better are Thrleys VS the PAcesetters? Good luck with your project! After doing the filter relocation, I would recommend it even with stock manifolds. Oil changes will be that much easier and the larger filter and additional oil capacity that much better for the engine. From what I have read here and on other forums, the Thorleys are better made. I have no experience with them but can say the Pacesetters, though functional, do not appear to have been made with pride. Link to comment Share on other sites More sharing options...
msavides Posted March 2, 2007 Share Posted March 2, 2007 I had no choice but to get the thorleys, as i live in california. and pacesetters are not carb approved. I have photos of my header install nightmare and oil filter relocation here. oil filter relocation is not really necessary with the thorleys but recommended if you do not like oil dripping all over the starter and rear of the oil pan. thorley install pics. select view now on page http://www2.snapfish.com/thumbnailshare/Al...165/t_=88532165 oil filter relocation pics select view now on page http://www2.snapfish.com/thumbnailshare/Al...165/t_=88532165 Mark Link to comment Share on other sites More sharing options...
Casey.T Posted March 2, 2007 Share Posted March 2, 2007 Iteresting place to mount the relo filter assembly.... -bounce- Link to comment Share on other sites More sharing options...
Guest SuperSon Posted March 2, 2007 Share Posted March 2, 2007 I would say thats an excellent place for the oil relo kit. no drips on the engine bay come time to replace it and since youre going to be underneath there anyway to remove the drain plug. You could probably fabricate an aluminum cover for it tho so rocks or what have you doesnt damage that filter. I like that spot Link to comment Share on other sites More sharing options...
msavides Posted March 2, 2007 Share Posted March 2, 2007 (edited) well if you have a manual transmission. Automatic transmission may pose a problem since they are a little wider. Dual filters are a nice touch as well Mark Edited March 2, 2007 by msavides Link to comment Share on other sites More sharing options...
M in KC Posted March 2, 2007 Share Posted March 2, 2007 I didn't have to relocate my oil filter with my Pacesetters. It's still a little PITA and you end up dribbling some oil on your starter. Link to comment Share on other sites More sharing options...
