    Found the missing shroud bolt so as of right now everything is ok, but not great.

    Also got the alternator bracket, a/c bracket(the one that covers it) and the power steering bracket sandblasted and shot 1 coat of clear on. MAN did they turn out nice with just the clear coat! :shock: Can't believe how nice a sandblaster works, also leaves the surface of the part much nicer. Im so getting a blaster for my garage. :grin: The lower A/C bracket isnt quite done yet. The hardest was the A/C bracket that kinda covers the compressor.

    Now to move onto the timing cover. I figure a good wire wheel, clear coat and then high temp buick red will do the trick. Right? :Do No:

    Quick question - why are you clearcoating the parts before you paint them?


    PS - I'm jealous you have access to a blaster. I NEEEEEED one!!!:spank: Right now my face looks like I was born in a coal mine, after using the wire wheel on the bench grinder all night on parts.

    You said it yourself. That way they wont rust right away. You are doing it on the '60. A flat high temp black will go over that in 2-3 coats probably.

    My eyes arent hurting that bad but someone before me had shot the window when the plastic wasn't on the glass so there are 2 small spots you can see in before it all goes completely invisible. Sand dies down and start again. My chest hurts more from leaning against the eastwood emblem though. :laugh:

    You do know P.O.R. 15 also makes a really great paint stripper?

    I'm only clearcoating the parts that are staying bare.

    All the parts that get painted, will be immediately painted the color they are supposed to be.

    I started on the Buick Green parts tonight, and a few other semi-gloss black parts now that I finally got the parts and paint shipped from CARS. Man, they are sloooooow.

    Ever realize how many stampings, marks and symbols gm put on just the power steering bracket? :Brow: I can with the blaster now. Also, dont you love it when the wires shoot out from the wheel? :error:

    I'll remember that, CARS = slow. :laugh:

    Got a few parts in, the gasket set from Felpro and two belts, the rest will come when I order it.

    I just removed the timing chain and cam gear. Found one cam bolt teetering on the oil pan about to fall it, but i rescued it, and found the other floating in the timing cover. I think they are the bolts, about half inch long and possibly half inch head? I think im going to clean up the intake alot! Remove the carb and box it up for storage, remove the valve covers and inspect the rockers as best i can from there for now. The crank timing gear is as dry as the desert. :Dou:

    Can I use a wire wheel on the timing cover? :Do No:

    Just removed carb as it is going to be replaced with a rebuilt one. Didnt like the idea that only rags would be where the carb was so i fabbed up a wood intake cover. :Brow: While removing some of the hoses from the carb, they were so dryed out they just snapped as if it was plastic. :error: Back to the garage! :)

    I like 'em too. The '60 is coming out alot cleaner than mine. Gotta return the engine degreaser and get simple green. :)

    Made a bit of progress. Cap and wires are off, i never really got around to marking the wires until the became in the way for everything I did.

    My driver's side head reads: 2
    4P 1241850 (probably not stage 1? stage 2? :laugh: )

    Removed the "wanna be hei" unit from passenger fenderwell. And it seems the mechanics put two bolts underneath the unit tha obviously belong to the engine, possibly a/c. Not to mention the bolts lying on the lower a/c bracket when I got it. Removed one of the a/c lines. Some oil came out after I put it on the floor but the R/12 is probably long gone. Still have one more to do and Im not sure how. (the one with the 1 1/8 nut attached to firewall box. Found and removed grease from positive and negative battery cables. Was going to remove the heater hoses but wasn't sure if there a continous hose through the firewall or not? :Do No: Removed fuel pump. Also, whats that thing laying on my drivers inner fenderwell with a bunch of vacuum lines attached to it and what does it do? Pulled the valve cover on driver side, got the number, inspected valves as best as i could, seem ok. Although the rockers move side to side just a tiny bit, but only some of them. None of them appear to be broken. I think I may just go forward with the work and worry about it if it presents itself. I havent cleaned the front of the engine as I would have liked to but thats because i dont want anything falling inside the heads or oil pan. Maybe when i put the cover back on, the simple green and a hard bristle brush will meet the engine. I forgot to take the pictures of the brackets. :Dou: Im bringing the timing cover to work to clean it, and possibly to school for the parts washer.

    Adam, does your motor consume any oil since your heads have been redone? I was told if i had them redone i run the risk of hurting the bottom end(rings) because there more compression now.

    Rob, if that thing is what I think it is, it should be your cruise control unit. Looks like it has one cable going to the transmission, and one going to the speedometer. I'm not 100% certain as to what the vaccum lines actually do, only that they operate the system.

    My motor consumes very little oil - typical of a 35 year-old engine with 85xxx miles on it. The only time I notice when I consume oil, is when I'm running at 2800-3000 RPM on long road trips. I have to put a quart in every 1000 miles or so on those trips. Otherwise, I never even have to top it off when driving around town.

    Don't worry about more compression - unless you have your heads milled a LOT (which you shouldn't) you should not have to worry about more compression. I had mine milled .010 to flatten out the surfaces. This is not enough to even worry about.

    Adam, what i think he means is that some compression gets lost through the guides and seals on worn heads. When the heads get redone, he's going to reclaim any lost compression back into the cylinders. I've had that happen on very high mileage cars. Makes more oil blow past the rings. I turned an 80 Caddy into a oil burning pig with a set of reconditioned heads. But that engine had 217,000 miles on it.

    Rob...I learned a very valuable lesson in my years of spinning wrenches...If it's not broken, dont fix it.

    I see...

    I hadn't heard of that before.:Do No:

    It's not a real high compression motor enayway, I don't imagine it'll make that much of a problem, depending on how worn the rest of the engine is.

    Thanks for the clarification Jason, and older auto parts guy at work was telling me this and I wasn't quite sure what he meant exactly. "if it ain't broke dont fix it" That really makes me about it, why do it? I guess i just am getting overly worried as I want to only do this once. You wouldn't happen to be spinning snap on, i know craftsman grips it well. :pp :moonu: :laugh:

    Thanks Tom, it makes sense now that i've seen it on some cars and not others.

    The local auto parts store can re-do both of them for me for only $150. I will find out what that $150 gets me though. And its not a pep girls, or autozone local store, its an old independent store. :) Also where im getting everything else, besides the new bolts for the buick.

    Are oil pressure gauges difficult to install? I need to get the Autometer Oil, Water combo.

    And nobody wants to tell me if my heads are Stage 1 or not? Fat chance they are! :laugh:

    Stage1 heads carry the same casting number as standard valve heads. You will not know unless you pull the heads to look. I don't believe Electras ever had the option for a HiPo 455, but there are always exceptions. Money makes things happen at the dealer (at least it used to)..

    Brought the timing cover to work as I remembered we had a Zep parts washer in the corner. My boss said it didnt work, but it actually did. So i cleaned the entire cover in the parts washer. Most of the paint on the cover is gone along with the oil. Oil filter is still stuck on. But the good news is the drain is slow so there the parts washer has 3 inches of oil in it at a time. So i'd lay it down when a customer came in and 30 minutes later i came back and did the same. I thought o myself I should remove the water pump, I did and every bolt is loose. Tomorrow it will be removed. Only 1 broke and that was when it was just removed from the car. :Dou: A trip to napa will allow me to get buick red high temp paint.

    Looks like you're diggin deep.. Seeing what you're up to makes me worry about not having a proper garage. Pheeeww...

    Well, if I would do that operation here, it would be in the open.

    Got a few parts in. Water pump, gasket set, timing chain and gears, oil pump rebuild kit.

    Now I will paint the valve covers, water pump, timing cover and thermostat elbow at work today. :) The timing cover will need to be cleaned a bit more, still a few places where paint remains. The driver's side valve cover was oily, the passenger on the other hand is something else! :puzzled:
