Thanks. You'd be surprised how many times I have to refer back to my own posts to revisit what I've done over the last few years. I expect that when this engine is finished I'll look at the Silver car with its 150,000 mile engine and decide to do that as well then refer back to my recent pages here.

Btw: I'm an addicted tinkerer with OCD tendencies. A lot of what I've done here is for the love of it rather than the need e.g. The existing oil return tubes were fine. I saw that they were inexpensive new so 'had' to change them.

It helps that the NZ climate is benign. These won't cause me any problems if I have to go back in there one day. That said I'm putting all new nuts on for insurance.
Thanks for this and thank you for a great thread. The information you and others provide is a real boon to those of us doing our own stuff.

Home for 36 hours then flying out for another two weeks. Time to just make sure I'm on the right track.

The refaced tappets look good albeit I had to Google the parkerised finish as I was expecting shiny chrome on the faces. It was done by a professional cam grinding firm so I have to trust them this is a suitable finish. The warning on the invoice about only using ZDDP rich oils in flat tappet engines is encouraging. The cost to reface four was USD 70.

New rings. I've had a practice with the old set. I need to be on my game with these to make sure I don't break them or possibly worse i.e. Install them upside down

Cylinder head temp sensor comes with everything needed. Same old connector unlike the new crank position sensors.

One annoyance with aging is the need for a lot of task lighting. There are numerous options with tower lights, rechargeable lights, head based lights however all of them have drawbacks.

I have a set of 8 LED panel lights to install but they need an electrician and a clear garage. I had this brain fade during the week and had proof of concept this afternoon. Overhead lighting that can be height adjusted and never needs recharging. Just a little fussy to get absolutely square and level but there's a clear improvement.

I am right there with you on shop lighting... I have a hand held led spot light and it drives me crazy... I had to point it off the object I am working on to get the light I wanted...
You have some exciting steps coming up with closing the case, will be following for sure. I walked to the edge of Abyss and looked, you're there in all it's glory.

I have another set of critical deliveries e.g a new nose bearing and then it's all on when I arrive back home in mid June. In some ways the anticipation is a lot of fun; it might be an anticlimax when it eventually starts up. Then it will game on for the Silver C4

Grrrr, PP substituted my specific Elring crankshaft seal order for Victor Reinz so I have to wait while the correct part goes through the shipping process.

On the good news front, a fellow NZ Rennlister, Spokes, has ordered a PDT 999. It's taking time for them to build as some parts were on back order but will be worth it when it arrives. I'll enjoy using it when I need to bleed the diff locks. New Motive bleed bottles purchased in anticipation.

Thanks. No, I'm a committed C4 fan. Apart from the planetary gear pins it's a robust system that expands the car's performance envelope. I've tracked the car extensively against a C2 and it was neck and neck in the dry but I walked away in the wet.

^^^ thanks for the insight ...

LOL i remember one of the back markers in our classic cars race (basically a free for all pre 1985) in a audi quattro that had really lived IYKWIM ... on formation lap the heavens open and Capris, GTAs, Darts, Pcars, Escorts etc... are all backed up and timid and the quattro comes past the whole lot of them from 20th to 1st (on the grass no less! his excuse being better visibility!) before T1!

... so if it didn't rain/snow much where you were, you'd consider it?

In the days before the prices got away on me I considered gutting a tipo and putting a 993 box in it. Something like Captain Ahab was doing. I think I'm more in love with the idea of agility and lightness than 2WD per se. I had a taste of the latter with my Turbo 3.6 and Cayman R.

The critical piece for closing the case has arrived, a new #8 bearing. I'll be putting the vernier all over this before installing it.
