I'm not sure about the compatibility here. The 3B p/s pump and system uses Pentosin but the urq/4k system uses ATF Dexron so I would suggest running the ATF. I don't have any experience of running ATF in a 3B pump, so don't know if this is possible.

Looked into it yesterday. I actually only have a stock urq pump. Not sure why I thought I had the 3B pump but I can't find it

Pat's 1983 URQ Alpine white #603 , 20V in progress

Postby Afterthought » Fri Oct 02, 2015 6:23 am

Got everything out but the steering rack.
Think I may pick up an HF soda blaster today to use for cleaning up the bay easily. Will have to put the subframe back on so I can roll the car outside but should help save time and get a better result in the engine bay.


Guess now I'm going to need ball joints, CV boots, and bushings.

Curious what is the best way to get that "knuckle" loose, just inside the car , that splined shaft that connects to the steering rack. I took the bolt out but can't get it loose . Everything else is loose on the rack.

The one that connects to the steering column?

I just let it soak in Kroil for a bit and used a big flat screwdriver to pry it off from inside the car.

Started working on a fix for the fenders so I can have them sprayed at the same time I do the engine bay.

So, had to sand down to bare metal then will sand and prime using a high build primer and sand again. Fixed the one ding while I was at it. I'm doing most the prep. work but It's going to be best best for me to farm this out and have the engine bay and fenders professionally sprayed.

Jim it will be looking great when everything is said and done . I will have to spend a day on the body total.- few hours to remove two panels inside the car then have pointless dent removal done. There are only two door dings total. Then probably a few hours to mask and remove the overspray off all the windows, then go at it with the buffer . Going to be a huge difference. That is going to be about the last thing I will tackle . Been focused on the mechanical side of things mostly .

Do not use wool on your windows, you're gonna scratch em. Use the blue shop towels or something similar that are "resistant" to thinner. Also get an aggressive thinner, not all are good for the job, some will do nothing and you'll rub for an hour, others you will be able to wipe that crap right off in a few seconds.
I've had some omni base coat thinner, wouldn't do crap lol, switched to some chromabase thinner and poof overspray wiped right off the clearcoat. Also watch for your rubber seals, they'll melt if you have the good stuff.

Will you be using epoxy sealer?

Coming along nice :thumbsup: :)

Yes its possible to scratch with steel wool but depends on what you use. Something like 4/0 steel wool youd have to try pretty hard. However the thinner works better as long as I'm careful with the plastic.
Ive never heard anything good about the Omni products either.

Still taking stuff apart, Cant wait to be putting together again.

Took everything down to the subframe and sandblasted that. Will get it coated today so it has a week minimum to "cure".
Can't decide if I'm going to just to black paint on the whole subframe or black paint on the top half then "undercoating" on the underside.

Took a break from paint bullshit to finally start at least putting something together. Started on the block.
The block has been jet tanked, resurfaced, cylinders honed. And a fresh coat of silver paint.

Starting point:

Moving along nicely!

Any plans to seam weld the subframes?

Just to keep the rust out? Or does it serve another purpose? Hadn't planned on it. The subframe is in really good shape no real corrosion .

As I recall (read about it on a thread on MG years back), it helps for rigidity over certain power levels.

Can't have enough project cars. My newest project car showed up today.
Image
...In the mail.

Well spent another 5 hours on paint prep. I'd rather kill myself than paint cars for a living.
I kind of screwed myself, I was poking around in the "drip tray?" area between the windshield and engine compartment and noticing all of the cracks in the protective rubber/plastic junk audi puts on there from the factory and accidentally cracked a piece of it off.It's bare factory body underneath, So I ended up having to chip the whole thing out and then sand that area too. That sucked, but it will look better in the end.
Image
Image



Got some primer sprayed in the areas in the engine bay that were sanded to bare metal.
Anything that has been sanded down to metal gets "acid etching" primer first, then sprayed in high build primer so it can be sanded smooth. Then will get painted in factory L90E alpine white.

Image
My goal is to hopefully be done with all the prep and sanding tomorrow. Then I can paint and never look back. Will start assembling the engine as much as I can, finish the subframe, and start going back together ASAP. Still have lots of work to do but the project keeps expanding.

Some cool extra stuff I found some where.

Piece I needed. Thank Marc!

Almost done with this mind numbing task of paint prep. Very close to being able to spray the bay.

It would be going faster if I didn't a couple of other projects taking up my time! But this one is my top priority.
Paint is next, maybe will be done by the end of this week if can spray the engine bay if everything goes well.
Also need the euro bumpers to be cleaned up and to spray the fenders
Image

If I end up Waiting on paint to dry, I only have a couple parts I need then I'm ready to build up the engine assuming I don't have anything else pop up to order.

Starting to put together the engine. Looking for torque values... Was planning on just using the s2.co.uk workshop manual. I think the AAN and 3B (and 7A) are the same for all the torque values?
Actually the gasket set I have is for an AAN too :huh: hopefully I can get by with this.

For the Arp head studs I'm going to do, 55 lb ft (3 stages 25, 40 then 55) then re-torque after a few heat cycles.

Question for those of you who are engine builders... Have you seen a wrist pin be a little bit tight or sticky? Installing the new DM Forged rods I got onto the pistons and noticed one doesn't want to rotate well. They are all tight but this one is tight enough it makes the engine very difficult to rotate by hand.
Again its new DM forged rods, stock pistons that have been cleaned. Everything was oiled lightly and used engine assembly lubricant when putting anything together. Wondering if this is an issue or not being that it is at 50 F and has never been run, may be something that needs to "run-in"

They should not bind at all. I have always had the machine shop hone the rods to match the wrist pins. They should be a little tight out of the box to make this possible.

was able to call in a favor from one of the machine shop guys at work. Got all my parts that were sandblasted run through a super heavy duty parts washer . So this takes care of any concerns I had about media .
