Harvs11 Posted 26November, 2013 Report Share Posted 26November, 2013 A little while back I noticed a loud rapid fire noise when on the loud pedal, and not a good noise. It didn't take long to work out that I was the newest victim of Porsche's experiment into exotic metallurgy. The Dilivar steel exhaust studs on 2 cylinders had snapped! This is becoming an all too common thing on aluminium block 911's. I decided to fix it now instead of waiting for more to let go and do further damage. After a lot of research and talking with people whom I trust on the subject, I decided that this is a job that I can do myself with a bit of help for some of the trickier stuff. So begins the adventure. First thing was to drop the engine. I took my time and managed this without any big c*(k-ups. Next was removal of the CIS induction. I want to disturb as little as possible so after taking out the alternator I lifted (with a helping hand from Dave W) the fuel intake and cowl all as one leaving the bare engine and gearbox. It's been a few nights in the shed cleaning 33 years of crud from the engine while waiting for the pelican to drop a bundle my way with a bunch of new parts, seals etc. It could have been worse. The "triangle of death" was not showing any leaks. Just built up dirt glued together by oil mist on the top. The underside was a worse with 3 out of 4 oil return tubes leaking as well as seepage from the number 3 cylinder/head joint. Engine is up on the stand now.

Mtheo72 Posted 26November, 2013 Report Share Posted 26November, 2013 Thanks mate. The good people at Autohaus Hamiltons will be my ticket out of the club. I'm a little delirious with the "while we're in there" options/possibilities. Now I wander what the market is for a nearing middle aged fat bloke who has very few talents? Anything for some lovely 964 cams..... Link to comment Share on other sites More sharing options...
Harvs11 Posted 26November, 2013 Author Report Share Posted 26November, 2013 By all reports you will be well looked after at Autohaus. Keep us up to date. Good luck. Link to comment Share on other sites More sharing options...
Mtheo72 Posted 26November, 2013 Report Share Posted 26November, 2013 Thanks again. I've only owned the car since Jan' this year. It's been a couple of times to Autohaus and the results each time have been exceptional. Only problem for me is it's a long cab ride home, to Canberra! Well worth it however.

twood Posted 26November, 2013 Report Share Posted 26November, 2013 I did my 964 motor for the same reasons. I replaced 2 broken divilar head studs, had the engine 90% reassembled and had a 3rd stud snap when under no stress. I pulled the whole top end down again and replaced all the divilar head stud with steel studs and have had no problems. The dilivar studs were around $35 per stud and the steel studs were about $11 - it soon adds up when you have 24 studs to replace. Link to comment Share on other sites More sharing options...
Russ Posted 26November, 2013 Report Share Posted 26November, 2013 wow great write up and pictures Harvs! I didn't know you could take the whole CIS system off in one go like that, that's great Link to comment Share on other sites More sharing options...
_Tony Posted 26November, 2013 Report Share Posted 26November, 2013 Harvs, good luck with the rebuild.. post as many updates/photos as you can.. btw, where did you get that engine stand? Link to comment Share on other sites More sharing options...
Harvs11 Posted 26November, 2013 Author Report Share Posted 26November, 2013 Thanks for the encouragement. I started this thread as a bit of pay back for all the articles,posts, threads that I've poured over gleaning a bit of knowledge on all things P. I have the same sickness where I find this stuff fascinating to watch. twood, I'm not going back to Dilivar studs, steel studs as used on the intake side will replace all the exhaust studs so I dont have to go back later. RussR, once the intake runners are unbolted from the heads and the cooling shroud is unscrewed, its just a couple of hose clamps and clips to take off the whole CIS unit. I'll try to do a weekly update. More time on the engine rather than posting every step. Link to comment Share on other sites More sharing options...

Harvs11 Posted 27November, 2013 Author Report Share Posted 27November, 2013 Aimr75, the engine stand is borrowed. It's a heavy duty unit previously used for a Chev big block. No prob's holding the 911. It's got the wide-set legs which makes it very stable when turning over the motor. T-bar style legs can be a bit tippy.

I have no need for one (Hopefully not for some time), but would like to tackle a job like this in future when i have to. Link to comment Share on other sites More sharing options...
Harvs11 Posted 27November, 2013 Author Report Share Posted 27November, 2013 I just found out that it was $69 special from ALDI ... Global purchasing power has it's advantages. Link to comment Share on other sites More sharing options...

Harvs11 Posted 27November, 2013 Author Report Share Posted 27November, 2013 Delivery arrived today. Ordered from Pelican just last Thursday, quickest yet. Included a full gasket kit. There's hours of fun sorting thru that lot identifying which seal/washer is what. It's bundled into 5-6 bags with each a mixture of various seals, no labels of the contents either Link to comment Share on other sites More sharing options...
