You will need to remove the distributor and its housing to change the oil sender or get down to the water temp sender. In extreme cases the intake manifold will need to come off too for extra access, especially if playing around with the coolant outlet from the head
Top tip..... make a new join/connector in the loom from top of engine to the back of head for oil, water and TTS connections. Install this short loom before installing the head or engine. Far easier then the reconnect to the rest of the top of engine loom. _________________ 1980 931 - forged pistons, Piper cam, K27/26 3257 6.10 hybrid turbo, 951 FMIC, custom intake, Mittelmotor dizzy & cam pulley, H&S exhaust, GAZ Gold, Fuch'ed, Quaife

Personally I would just remove the distributor, leave its housing. The bolts for the housing are a real pain to get to with the head installed, and just having the distributor out of the way I would think would be enough room... _________________ Vaughan Scott

I would first go down to the hardware store and get a couple of spare nuts for the inevitable loss. I then put a ittle grease on a finger and embed the nut in the grease, reach down only needing one finger and start it on. _________________ Mike

The distributor itself is not installed, just the housing, FYI.
I can definitely see how making the new connector and fitting the wires before installing the head would have been a great idea. Wish I had thought of it at the time!
Definitely should get some extra nuts. The damn things seem to be aluminum, so I can't even fish them out with my magnet. _________________ -----------------------------------------

Stainless, actually.
And the engine wiring harness does in fact split at the firewall, yes, easier to install all on the engine then only plug in after the thing's bolted in. _________________ Vaughan Scott

In the end I used a combination of recommended techniques. I superglued the nut to my finger and then quickly positioned it on the post and broke it loose.
One thing I just noticed....my ARP head stud kit came with no washers, just studs and nuts. When I was looking back over the instructions to get the torque values, I noticed it mentioned washers. I had assumed the ARP kit didn't need any if it didn't have any in the box. Anyone use the Cosworth Sierra kit on a 924 and recall if they had washers or not? _________________ -----------------------------------------

I seem to recall reusing the stock washers.
It was only 3 weeks ago, but I have been busy... LOL _________________ Vaughan Scott

I actually found the little bag of ARP washers that did indeed come in the box. Oops. I hadn't torqued anything down, so no harm done.

I'm getting terrifyingly close to being ready to see if it will run again.
I noticed the marking on my crank pulley does not exactly match the mark on the flywheel for TDC. It's close, but not exact. I went with the flywheel mark, since that is what I will use to set timing.
I used a wrench to turn the motor over a few times...had a moment of panic when I heard a grinding sound, but it was just the coolant line bracket scraping against the crank pulley _________________ -----------------------------------------

Yeah, the rear/flywheel mark will be the most accurate; as long as the front pulley is within 60 degrees, you've got it all straight. _________________ Vaughan Scott

I meant to ask in the previous post but got distracted: How do you guys torque down the cam sprocket and crank bolts? For my 928 I had a flywheel lock but I haven't seen anything like that for this car. I don't think putting it in gear will do the trick, at least not for the crank bolt. Wedge a pry bar against the flywheel teeth through the lower observation hole in the bell housing maybe? Seems a bit dodgy... _________________ -----------------------------------------

For the crank bolt - I stuck a bar through a couple of flywheel bolts, locked against the engine stand. Obviously you're talking about while installed... I'd suggest in gear, park brake on, and a wheel chock in the appropriate direction.
Unless you have the flywheel lock that goes in place of the starter; I have one, but as mentioned last time I installed/torqued the crank bolt was when the engine was on the stand for rebuild last month, so couldn't use the lock (since it mounts to the bellhousing).
I rarely remove the cam pulley... though I did replace mine with new this year, while in the car, think I just held the crank bolt, since the torque is lower from what I remember... _________________ Vaughan Scott

OK, that all makes sense. For the 928, the flywheel lock goes in place of the slave cylinder, so super easy to install and remove. Not the the starter is hard...
The wheel chock was the one piece there that I didn't add....that would definitely help, I will try it.

I use a socket on a breaker bar and hit it with a cheater pipe from the bottom a bunch of times until it mostly stops tightening..
“Impact”
I call it “Harley tight”.. _________________ 80 Turbo - Slightly Modified |
