Figured out the misfire:

Zero compression in cyl. #5

:cry:

Zero compression happens if a piston has massive hole, totally smashed rings, a valve is burnt beyond recognition, or a valve is simply stuck open.

Given that the motor sat for 8 years, I was betting that a valve had frozen open.

Definitely didn't want to pull the head, so I hoped that a little bit of Marvel Mystery Oil might have some magic in it for the old lump.

So I pulled the intake manifold and exhaust manifold and hosed the cylinders with Marvel Mystery Oil (which many people say is just ATF)

Image
Image

I think it worked. I let that all sit a few days, re-assembled and went for a drive.

Still lots of smoke, engine seemed to be shaking still. But I got out onto the road and the car drove better, smoother.

I went to the Naval base on Alameda island and used Sea Foam in the engine.

After that, everything seemed to run really well

I got to drive around for 30 mins and all was well. Oil pressure good, coolant temps steady.

The car feels really fast too! Spins the tires through first gear! Makes a great noise.

Except for the exhaust leak, and the exhaust pipe banging around on everything. Major bummer. Needs to go back to the shop to get fixed.

Oh well. One thing at a time.

Yes they go well with the 7M.The MX13 I did a few years back would fry the tyres in the first 3 gears with no hesitation.If you took off slow then flattened it it would lay rubber for as long as you wanted with a play of the accelerator.Same with 2nd gear going round corners.Good fun.You will get there with yours it all takes time.
Cheers Brett.

Here's a quick video from my last drive. You can hear how much better the engine is running. Still has an exhaust leak. Need to have the shop add a flex joint to fix that.

Anyway, the car is a hoot to drive. Brakes need work, as right now the car accelerates faster than it stops! :shock:

Thanks Whit, I'm hoping the gauges are at least that old! However old they are, I haven't seen a set similar. More importantly, they work!

Got to spend some time with the car today. A few big projects going all at once.

1. brakes. Have had issues with the rears not releasing pressure, and the one caliper in the front working much better than the other. Which meant that the car had no brakes in the rear and and would dive hard to the right in the front. Not fun. All I can do is order new brake hoses and hope that was the problem. Updates on that later.

2. Shocks. Bought some Ultima brand shocks off ebay for $80. Cheap-o shocks, but better than nothing. Super easy to install on these old cars. Just unbolt and drop out! In with the new. One hour total. Rear doesn't sag anymore, but now the fronts are way high. Gonna have to cut springs soon.

Image
Image

3. Interior. Haven't had front carpets in for a long time. Rear carpets were there but gross. Pulled everything out to install new carpets. Phase one is cleaning.

Image

Eww

Image
Image
Image

This has been here almost 35 years!

Image

Also hammered out the bumper enough to re-fit. Seeing the rear of the car almost straight makes me very happy!

Image
Image

And one more shot just because I like looking at the old thing

Finished the carpet today. Like I do everything, I guessed once and cut 50 times. That's not a good method. I should have covered the front first, because I ran out of carpet after covering the rear.

I'll have to order more carpet to do the front properly. But for now, the car is majorly improved. I won't miss that ugly floor one bit.

Sorry about the photos. Strong light all day.

Odd problem when driving for a bit, a wobble or shake of some kind would show up. Because the wobble wasn't there when cold, I thought it might be the rear drums sticking. So I bought new wheel cylinders and got to work.

Trouble from the outset. Turns out the wheels pushed the drum retainer screw back, warping the drum and hub. Screw was jammed.

So jammed, that my stripped screw extractor snapped off in the head of the screw!

Image

I don't have any photos after this. I was pissed off and just got to work. Had to grind out the screw with a disk grinder. Hub slightly bent, but was hoping it wouldn't effect things and I could still drive.

Got it all back together at last ( I HATE drum brakes! Why so complicated?! )

And all seemed pretty good. Had a great drive, wobble and shake free. As a bonus, brakes feel much better.

Then disaster!

Image

The nylon oil pressure gauge tube disintegrated at the engine block under the manifold. Oil everywhere!

Parked the car on some street, walked home and got the stock oil pressure switch to get the car home.

Next project; replace nylon tube and replace center support bearing.

Anyone know if the Corona Mark II drive shaft carrier bearing has the same part number as other, more common cars?

I might offer up that hydraulically operated oil pressure gauges are not the best for the street. I know you like your gauge pack (as do I!), and I'm sure people have run great quality oil pressure gauge lines for decades on the street with no problem. I just think that the fast acting behavior of a hydraulic setup is great for a track car, but electronic setups are quite fine for a street car and you can take this risk out of the equation. Just my $0.02 :) No criticism, mind you... your work is still inspiring me to get going on my MX13. :D

Also.... Ta Da! http://www.autozone.com/autozone/parts/ ... 4_25957_0_

(let me know if that link doesn't work for you)

Timken 206FF. That's accord to THEM. I haven't confirmed it, but I will sometime soon. You might beat me to it, though!

According to rock auto the dimensions are:

Bore=1.1811", Outer Diameter=2.4409", Width=0.6299"

Which translates to a 30mm bore, an OD of 62mm, and a Width of 16mm. Let me know if that seems right. I probably won't be under my car for 3 more months. :(

Thank you!

The problem I'm having with the center support bearing is the rubber is totally rotten. Hopefully at least one of those parts on autozone comes attached to the rubber part I need. Thanks to your research, I'll be able to find a replacement MUCH more easily! Thank you!


You're right about the gauges. I know the oil lines are a liability. I will replace the line with a copper line, and if I ever have another problem I'll just un-do it and never go back.

Was fussing with some wires and the coolant temp sensor for the ECU just fell out. $15 replacement. Can't tell immediately if the car runs differently with the new part. Engine still isn't running just right.

I had one day of driving the car with few problems. ONE. And it was fantastic! All my hard work finally paying off, and my dream realized.

Then something new happened. I start the car and a HUGE cloud of white smoke billows out from the tail pipe! And now the engine won't idle, and generally doesn't feel right. Worse than before.

Image
Image

I didn't bother running another compression test. I decided the cylinder head just has too many issues, and I want to replace it.

So I found a replacement cylinder head (more on that later) and got to work pulling the old head. It's a lot of work to drain the oil, coolant, pull radiator, intake manifold, and everything else attached to the head!

Image

Spark plugs. You can see the really cruddy plug with lots of oil fouling and water corrosion is cylinder #5, the problem cylinder.

Everything removed, undoing head bolts.

Image

Cylinder head off! Didn't even put up a fight.

Image

Close ups of the cylinders. Bores don't show much of the hone marks, but they are still there. Cyl #4 had a score mark, but I couldn't feel it with my finger. Hopefully it's not an issue.

Image
Image
Image

No signs of a blown head gasket so far as I can tell, but that doesn't mean anything. I may just not know what to look for.

Valves look dirty, but nothing is obviously wrong

Image

EXCEPT THE MASSIVE GAPING HOLE

Image

Well, there's my problem. If I only had one that is.

I would bet that you have a cracked water jacket on that head, probably no valve seals, and some worn piston rings or 10. I would put new rings in, and replace the head to avoid any future problems. If you do happen to find the crack, you can get someone to weld it back and machine the head surface back down. Thats what I had done to my 22re head.

Earlier I alluded to finding a replacement cylinder head.

I was at Performance Options in Oakland the other week and asked what was under the tarp in the back corner:

Image

Performance Options had a customer bring in a Supra with a recently rebuilt engine that had slight rod knock. Instead of repairing the engine, they just swapped a 1JZ in. The fresh 7M just sat there until I came along.

Image]

I struck a deal with the shop and pulled the cylinder head so I could just swap onto my existing block without having to pull the whole engine or have to rebuild the current cylinder head. Easy fix!

Image

I also got ALL the accessories to the engine. Intake manifold, sensors, ECU and harness, 3 inch downpipe, rebuilt turbo. Everything.

Oh, did I mention this is a 7M-GTE?

Image
