I was told to throw them in the ocean, but I guess I'll keep them. I've got quad square era beauty rings, if I find a set of early hub caps to match ill think about throwing them back on.
I really forgot how much different the 70s 240 is from 80s, same car yes but totally different feel inside and out

Much better then my solution of pulling the injector, cranking and watch it "spray" all over the valve cover.

Put a full tank of gas in it today and took it down the highway, man do I miss overdrive. Tanked Siena into learning manual so it will likely get an M47 if I can figure out a Spedo solution.

Temp gauge went up quite a bit, anyone know what temp I should see with an IR thermometer at the housing/head? It's got a new water pump, thermostats opening and heater works. Pretty sure all the air is out by now so I'm beginning to not trust the gauge. PO had an aftermarket one installed and the original wire cut so it seems he didn't trust it either...

hmm maybe 180 to 190 with a heat gun? Check the runners on the ex manifold also. Should all be pretty close ish. Cast iron glows at 890f or so lol.
Yeah just have to power the pumps on while you lift the air door.

I was getting 204° off the head, runners 1 and 4 on the exhaust where about 100° above 2&3 so definitely lean there. None close to glowing (all around 5-600) but I did get my 90+ and TD06 hotside to glow once in my wagon. Pulled the Injectors and soaked them in diesel fuel system cleaner, then backflushed with poorly with the same cleaner and breakclean.
20200901-200329

Two now spray a mist, one sprays a few small streams with a good bit of pressure but one still dribbles a little. Time to watch more Bosch CIS training videos from before I was born.

Going to clean them again and or install the second set I bought, as far as the temp I'm thinking tropical thermostat and install my R-Sport cluster....for diagnostic purposes of couse, don't want a faulty gauge giving a bad reading.

Been driving matcha on lunch and to pick up stuff around town, waxed it some but you can't tell between the smoke/ash and my ****ty camera
20200910-130343

I installed the injectors, along with new Orings on all 4, copper core NGK plugs, Bosche cap and rotor and bougie cord wires. Misfire is definitely better but still idles a little shaky. Got out a timing light and with the vacuum advance disconnect it's at 15° as stated on the emmisions sticker. With it connected at about 5° at idle. Idles a lot better at 5° then 15°. I've got the vacuum advance ran straight to the manifold. Seems it differs in several diagrams I've seen. This being a 76 California car it's got about 12 extra vacuum lines I gotta figure out.

Went and did some other maintenance stuff it needed. Pads and rotors up front, rear pads, trunk strut and cluster voltage regulator. Regulator stopped the temp gauge issue, holds steady a little under half now, glad it wasn't a botched head gasket.
When dreplacing the trunk strut (singular, other side has a locking mechanism) I found it was the original strut from 1976, wild to see an original part like that, gotta see if I can rebuild the thing for ****s and giggles

Awesome! Truly a 70s color. Nice save, seems mostly solid. (Haven't seen a cylinder head in that bad shape for quite a while.) Glad to see you're having fun bringing this thing back to life.

I wonder if that green carpet would have cleaned up? Too bad I didn't see this thread in time to make any recommendations. "Lifter 1" is my go-to chemical. The red can for upholstery, blue can for carpets. It'll do an admirable job on the ugliest stuff I've tried -- probably 10-yr-old coffee stains or worse.

Pretty much forgot about this car, walked past it in the backyard now and then but otherwise untouched since the carpet. Mostly been unable to drive it because of a pretty aggressive leak from the steering rack.

Got reminded I had it again. Went camping this weekend, brought the other, other, other, other 245. Great time and great spot for sleeping in a wagon, but imagine if the wagon was green.
Snapchat-742442146

So I gotta pick back up on fixing matcha, back to the bay it goes
PXL-20210518-021348997

Got a steering rack from the Oakland PnP a while back, installed it today, no more puddle after a bit of idling.
PXL-20210518-021356944-MP

Also fixed some of the vacuum issues, being an early 76 California car it's got a specific vacuum routing, got it all set besides the thermostat valve (1). The replacement head isn't threaded for one, so it's clearly not installed.
vac-B21-F-76-77-V1

I assume the valve is open when cold and closed hot? I've yet to find solid info on it, if anyone can beat me to the specs info would be much appreciated

PXL-20210518-033808800

But hey it's back on the road, time to convince her to let me manual swap it

Running the car around a little yesterday, took it by my parents where it met one of the other 245s. Little rough warm start after sitting, gonna check fuel pressure(s) soon.
PXL-20210519-011303828-MP

Tried to give it a wash to be met by water leaking into the hatch, all over the electrical diag tools I brought home

PXL-20210519-013509309

Looks like it won't be getting washed again until I get a new hatch seal, PnP run this weekend. Also yet again highway cruising in 3rd sucks, needs manual, need to convince SO

Did some more learning on Kjet Friday and Saturday, after reading threw a few greenbooks while actually looking at the system it makes way more sense.

Set up the tester to look at both line and control pressure, unfortunately I didn't have the fittings to do both with the valve but it's easy enough to swap the gauge with the quick disconnect fittings.

PXL-20210522-025256277

First control pressure....hmm 70psi... So clearly I'm tapped in at the wrong place and getting line pressure measurements right

PXL-20210522-221149441

Nope, triple checked the diagram, this is control pressure, popped the return line off the CPR, no flow from the CPR side, pulled it to find the screens chocked full of debris.

PXL-20210522-025548837
PXL-20210522-192806416

Pulled the unit apart, looks pretty crusty inside too.

PXL-20210522-193743578
Gave it a good cleaning (still need to bite the bullet on an ultrasonic cleaner) removed the screens, no more clog
PXL-20210522-204306072

Checked resistance, 26ohms, build it back up and reinstalled, pressure now follows the graph perfectly, 28psi at 76°, 54psi after about 3:30 powering the bimetal strip
PXL-20210522-211702041
PXL-20210522-214510247

Rest pressure drops way to fast still, combined with a loud pump I'm feeling fuel accumulator, but may remove the CPR again and either flip or replace the upper diaphragm.

Pulled the injectors again aswell, nearly melted some red solo cups over the valve cover to prove the injectors sprayed a nice pattern and had even flow, seem good on that side of the injection system.

Then moved to vacuum leaks again, didn't get to really sort them out last time I worked on the car.
PXL-20210523-000146681-MP

Found a good handful, replaced the orings on the cold start injector and idle screw. Added a few hose clamps and trimmed one line that was stretched at the end. Only remaining bit of unmetered air is getting sucked in from the EGR valve, leaks some smoke for what looks like the seal around the rod?

PXL-20210523-003909960

Still does some rough running on start/warmup, going to take a look at the auxiliary air valve tomorrow later today along with valve lash. No PNP run this weekend

…loud pump, are you sure that the in-tank pump is performing properly? Small rubber connector tube above the pump torn?
I fought some rough running with my Kjet setup and the fix was a new in-tank pump. The one I had in there originally had a crack at the outlet housing. Once it was providing enough fuel the main pump got quiet and it ran like a champ. I ended up using the ipd “upgrade” pump, YMMV.

From what I'm reading this car doesn't have an in tank pump, I'll double check one hasn't already been added but if not I may look into the bulletin to retrofit one.

PXL-20210524-005153788


Got tired of the drone on the highway, restored the exhaust to stock
PXL-20210523-211016925
PXL-20210523-235417351-MP

Sounds much quieter, highway cruising isn't ideal still, but much more bearable

PXL-20210524-001605642

Spedo is off by ~10mph, but it still did nearly 80 without sounding terrible. After driving her around in the car this week "we" have decided on an 4 speed auto, need to check if my AW71 is a roller bearing or can be converted to cable drive

No in tank thats correct. If its got the small opening sending unit vs the newer one it has no intank pump. Get an updated tank if you want one or can add one in there. If you want my 77 tank you can have it. It needs to be cleaned out though from old gas.

Did the valve adjustment after work today, man what a difference

PXL-20210526-005644725

Between measuring the shims and trying to remember/interprete my notes it was more work to get the right shims then pull the cam. Converting from metric to imperial then back didn't help

PXL-20210526-023959730

Got it back together and it idles much smoother, if it wasn't for the fuel pump you could bairly tell it's running. Gonna have to bust out the timing light to set idle speed, can't do it by how much the motor shakes anymore

PXL-20210526-043408811

This thing is a few steps away from being ready to rotate in for daily duty, current tags and it could do around town for her quite well.

Double check the rotor tangs on the dizzy to see if they are lined up. Had one on my 80 wagon thought it was the t belt but the rotor tangs were way off. The tangs for the mag pick up i mean.

My wording there wasn't the best.

I mean I gotta set idle RPM, timing is already set and good. It just runs so much better you can't tell when it's too low anymore.

My timing light has an RPM function and the car doesn't have a Tach

PXL-20210524-001610816

Or I could install my Tach

If I started flooring it at 1pm it would probably read about the same until late afternoon.

Got AW71 swap parts today, along with rear hatch gasket, rearview mirror and sun visors that arnt just powder filled bags. Hopefully next weekend I'll get a 4th gear

Also gave the car a wash Friday, a lot of the green is coming back, going to start polishing and waxing soon

Way back when our 1980 DL was a young puppy, the best I could coax out of it was a 22 second 0-60 time. (4spd no OD; no idea of the gearing.) I'll be curious to see what you can do with your wagon.

Nice job diagnosing and cleaning out the fuel system... those K-jet systems work remarkably well when new, and are remarkably expensive when not.

I'm both impressed and a little envious of your working space. I've done a wee bit of stuff in a shop with a lift, but mostly I've spent decades wriggling around on my back. That tends to dampen the enthusiasm somewhat.

The car feel pretty peppy for what it is, I'll pretend the B cam makes it a racecar.

Working on cars at the shop is such an awesome privilege, using a lift and other shop tools makes everything a breeze, but I've gotten too used to it, bench pressing transmissions is 20x worce now that I've seen how easy it can be. Other issue is I can't have stuff torn apart when 8am rolls around, so it's either little stuff after work or get it all done over a weekend.


Seats have been a mess since I got the car, tired of sitting on a towel and still getting foam on my ass

PXL-20210531-160342060

Picked up some early brown tweed seats a while back from the Oakland PnP, not the correct vinyl for a wagon but MUCH better

PXL-20210531-161522888

A little sun faded so she dyed the fabric brown again, took a few coats but it matches the rest of the interior nicely

PXL-20210531-202755549-MP
PXL-20210601-045217838

Also got in a rear view mirror and some "new" visors (nice foam, not bags of powder)

PXL-20210531-224338873-MP

And a "new" hatch seal, plus cleaned and polished the rear cargo area trim (not pictured, but trust me it's sexy)
