Pretty clever! I've just cut the throttle cam arm off with a band saw.

Had some time today again (no rain, just gloom).

- Flat-filed the part of the cam box that Van said I should to prevent leaks.

- Replaced the gasket in the back of the cam box. Is that cork gasket gonna hold up? I put it on dry without gasket maker. I didn't tighten the 3 bolts that much as the cork was beginning to crush. I'm not sure I like the cork. What do you guys suggest???

- Re-installed the rear part of the cam sprocket housing (the PET diagram calls it the camshaft bearing). There's a bushing there that I also replaced but I don't know what it's for (it's a white piece in the picture).

- New cam seal.

- Installed the cam sprocket, the new cam driver to replace the one I obliterated with my grinder. That part wasn't cheap. $95 !!!!

- I installed the new cheesehead bolt and torqued it to the correct 50 ft-lbs. I thought it'd be safer to install this now before it's on the head. I would hate the valves and pistons to collide.

She is up and running!!!!!!

I put back the radiator fans and the final exhaust gasket after jacking up the car. Battery's dead so we had to jumpstart. No extra bolts/nuts. The only booboo I did was I forgot to plug the AFM (air flow meter). We were wondering why it wouldn't stay started unless we gave it ether. We saw the cable, plugged it in, and it started.

I need to go get a battery so we can drive her around to gain confidence. Need to check for leaks too.

Here are a couple of videos:

Thanks to everyone for the help. I knew that if I were in a jam, I could count on the members of this forum for help. That's part of what gave me the confidence to tackle this project.

Thanks.

BTW, Van, you mentioned that the two lifters which I could push in had bad check valves so I ordered two new ones. The new ones exhibited the same characteristics of being able to be pushed in. Is that because they aren't filled with oil yet? I put them in anyway since I already have them.

Congrats!

Re the lifters, yes that's normal for new lifters that haven't filled will oil yet.

Just a quick update, guys. She is running fine. No overheating. No oil leaks. No coolant leaks. No mixing of oil and water. So far so good. At first, water level was getting low. We think it's because she was burping. Later on, water level didn't go lower anymore. We're starting to drive her farther and farther to gain confidence.

Default Runs hot now

Hi again. She sprung a leak at the 30-yr old radiator and was running a bit hot at idle. We decided to replace the radiator along with the hose that comes from the expansion tank. Bled the system per proper procedure. The fans come on at high speed when the temp gets a tad past 1/2.

HOWEVER, she runs hot at idle. Temp gauge gets past the 3/4 mark and gets to 7/8. As I said, I don't think there's air in the system because we bled it using the bleed screw. Fans come on at the right moment. I've also noticed that, on a separate occasion, once it got to the 3/4 mark, I revved it to 2000 RPM and the temp held at 3/4 until the traffic light turned green and I had to go.

Any ideas from the experts? Goofy thermostat? What else could it be?
