944 Turbo S Engine Rebuild Thread

Note to self, next time you build hoses don’t spend £80 on fittings and £20 on hose. Hose was crap and the rubber had split where the fitting went through, there is a reason the proper Aeroquip stuff is £15-20 a metre.
Wanted the car back and sorted so paid a local place to make me some hoses up and it cost the same as it would’ve done if I’d DIY-ed them properly in the first place. But with braided hose, crimped ends, pressure tested and warrantied all for just under £150 and turned round in a day!

The previous owner of my car removed all the aircon system and lines - cutting them off just after they came out of the bulkhead [

While I had the engine out I replaced all the lines with the correct new seals, compressor, receiver drier etc. but never got around to sorting it out.
Tried to pull a vacuum last week to no avail, got the nitrogen bottle on it and found a pinhole on the bottom of one of the hardpipes on the condenser. Toyed with attempting to braze it up but the condenser wasn’t in the best shape so have a new one on its way.
I‘ve got every faith that all this will do is lead me along to the next failure point - that’s the 944 way []

I've been down this road. I killed a perfectly good AC pump's nose seal due to an overtightened drive belt [&:]. Got a remanufactured one for about £350 and it's been all good since. I've also been through 2 condensers as they are positioned to get smashed by everything you drive over. I found the weak point to be be the inlet, which is where my 2nd one failed, so this time I've given that area a good coat of underseal. It's not given me a problem since I changed it 8 months ago, although 6 of those months the car has sat without an engine......

Without bad luck I’d have no luck at all - one of my oil hoses started leaking. Looks like nothing but was dripping down into the airflow so a lovely puddle in the undertray and splitter and some free rustproofing for the driver’s side floor pan too.
Took it back and it was replaced the same day - back on and car is continent again (for now at least - will keep an eye on the other 2).

This was the reason for my trip, a "spare” 3.0 16v Turbo engine that a member on here and Tipec had built up.
I guess we have different ideas of what constitutes a lockdown project - I painted the fence!
Sleeved block, forged and lightened internals, many new and refurbished parts - need to form a plan of attack.

Balance Shafts had been deleted on the engine but I wanted to reinstate them so first port of call was to assess the viability of doing this.
I had a set of shafts and 2 vapour blasted front housing mounts (as the ones on the engine had been welded up) but first needed to get inside the main housings. The oil feeds had been tapped and blocked with grub screws - if these weren’t coming out then it was a no go. Luckily, once the thread lock gave way with a reassuring click then they came out no bother so the next step was to put in a big parts order from OPC.

Also needed the upper balance shaft cover drilling and threading for the turbo oil feed - most people take a feed from the oil sender so as not to disturb the housings, but as they were off anyway it made sense to do it the factory way. Took the parts along to a local engineering place I use and got him to press out the old balance shaft front bushings and put the new ones in too. If anyone is attempting this job in the future - he knocked up a little tool from bar stock to do this cleanly, would be happy to pay it forward!
