phazed Posted October 20, 2023 Report Share Posted October 20, 2023 Drilled out four exhaust manifold sheared bolts and chased out the threads of two. Take off lunch and coffee breaks, That took about 4 1/2 hours! Should be finished by Sunday week at this rate! Quote Link to comment Share on other sites More sharing options...

kdh Posted October 20, 2023 Report Share Posted October 20, 2023 (edited) Today, I cursed two products: Autoglym roof cleaner and Carpro Perl black trim reviver. Both not up to the job. Carpro Perl had the windscreen wiper plastic area returned to its milky grey within 4 days, Autoglym roof cleaner just didn’t work. Surfex HD worked on the roof up to a point and the search for a decent black trim restorer continues, but I think I’ve tried them all now.

kdh Posted October 20, 2023 Report Share Posted October 20, 2023 (edited) Thanks very much, never heard of it. I’ve looked on Amazon but there are a few variables. Any preference? Edited October 20, 2023 by kdh Quote Link to comment Share on other sites More sharing options...

I think the key to making this job painless is to have the car in the air rather than being laid on your back getting caked up in rust and dust as you struggle away. Some people have been very lucky with this job diy such as @Terryg I wasn't just as lucky and decided it was less painful to just take the car to my mechanic. After a few snapped, I caked them up in penetration oils and actually my mechanic managed to drill out and not have to tap any of the bolt threads. But again that's the difference in position under the car. Quote Link to comment Share on other sites More sharing options...

It the car is fully int eh air I might tackle it with the jig, but as one bolt head has already gone completely, I'm not sure how the gasket is sealing to be honest, and the general condition of everything under a 23 years old car that seems to have spent a long time outside, mine will go to Dove House when the time comes. Perhaps mine is just especially bad and so giving me the wrong perspective. Quote Link to comment Share on other sites More sharing options...
phazed Posted October 21, 2023 Report Share Posted October 21, 2023 I am fortunate enough to have a 2 Post lift at home and of course using the jig makes the job doable, although no easy task. All that drilling upwards for hours while wearing protective goggles et cetera is no fun at all. My wife is returning tomorrow so this mornings jobs I’ve been walking the dog, tending to our chickens and ducks and filling the recycling bin with empty bottles! I can’t find anything else useful to do, so I need to go back out into the garage for a few hours. I’m sure I can find another distraction later!

ATM Posted October 21, 2023 Report Share Posted October 21, 2023 On 10/17/2023 at 5:40 PM, ATM said: Ok lads You can let the ladies know I got it up Driveshafts off The other side is just as bad Hopefully I can get these rebuilt with new rubbers If anyone has any tips for doing this or finding new rubbers please let me know, thanks Quote Link to comment Share on other sites More sharing options...
½cwt Posted October 21, 2023 Report Share Posted October 21, 2023 The rubbers can be replaced with a common after market part and the same fits both ends of the shaft and are about £15 each, I got GKN/Lobro ones from D911 but they are not listing them at the moment, on Autodoc 304115 LÖBRO Bellow Set, drive shaft 81,00 mm, NBR (nitrile butadiene rubber) ▷ AUTODOC price and review for a 6 speed. As long as the actual joints are OK you can de-grease and re-grease them, the grease came with the bellows in the kit above. You can strip the inboard end to component parts and inspect for any wear and pitting. I did this nearly 5 years ago now and they are still running fine. Outboard end, which you can't take apart, you can flush to remove all grease and then inspect and the outside should be cleaned of rust and painted to lengthen life too. Porsche part numbers are 996 332 293 00 for a 5 speed or 928 332 293 02 for a 6 speed version, 5 speed Lobro from Autodoc is 307225 LÖBRO Bellow Set, drive shaft 78,5 mm, NBR (nitrile butadiene rubber) ▷ AUTODOC price and review. 1 Quote Link to comment Share on other sites More sharing options...
kdh Posted October 21, 2023 Report Share Posted October 21, 2023 Investigation into why the Passenger side, side vent is weak. it wouldn’t normally bother me but in this weather it doesn’t quite clear the misted up passenger window. I checked under the bonnet for leaves but couldn’t see any. Anyone had this problem? tia Quote Link to comment Share on other sites More sharing options...
phazed Posted October 21, 2023 Report Share Posted October 21, 2023 Coincidentally, the same happened on the left side of my windscreen yesterday in my old Rangie . Put on the AC and it disappears instantly but a bit of a puzzle all the same. Quote Link to comment Share on other sites More sharing options...
phazed Posted October 21, 2023 Report Share Posted October 21, 2023 A few more hours this afternoon and now have one cylinder head bank with six broken manifold bolts removed and six nicely tapped holes ready to receive a new manifold. No prizes for guessing what I will be doing tomorrow on the other bank! Quote Link to comment Share on other sites More sharing options...
edc Posted October 21, 2023 Report Share Posted October 21, 2023 I guess you will do some basic port match/clean up for head and manifold. Watch also for the gasket protruding. Quote Link to comment Share on other sites More sharing options...
phazed Posted October 21, 2023 Report Share Posted October 21, 2023 Was going to have a basic check and yes I will check the gaskets. It seems to be quite common with generic gaskets. Not going over the top with this car, as with any 21-year-old car, you don’t know what it’s been through all though sounds nice and quiet. Would quite like to get hold of another 3.2 engine and take it apart for fun and knowledge and do a basic rebuild for the future… Quote Link to comment Share on other sites More sharing options...

Also they ain't cheap to buy (£2.5k upwards) or rebuild. Quote Link to comment Share on other sites More sharing options...
