Also,

I agree with you on the 1194. That stuff, seemed to of set, to quickly for comfort.

I was a little bit surprised.

I also used a very minuscule amount of 574 on webs.

Although, I installed my heads first using the cam shaft housings as a dry fit guide, in order to be quick enough for the Curil T, not to set up on the base gaskets.

Then I installed the cam housings and made sure the cams turned freely.

I'm really glad I did it this way, especially with the Lubro Moly entering in to the mix.

Mike.

Leakproof - you case is spotless. My wife has been pretty tolerant, not sure she would embrace the case in the living room. Also, if you carried the short block up a flight of steps you are much more of a stud than me.

Actually, the tech data sheet says curil-t is non-hardening and requires 5-10 minutes before parts are pressed together. I probably didn't wait that long, so hopefully, it won't impact the seal. I did the same where I kept spinning the camshaft to confirm the towers weren't sealed.

Greg,

I was not aware of the 5 to 10 minute protocol on the Curil T.

I just read the directions on the box and came up with that working time.

Spent a lot of time getting the oil off the base gaskets, a real P.I.T.A.

My fifteen year old daughter, helped me carry the engine up. I'm not that much of a stud. But thanks.

Oh, my wife wouldn't be so lenient about the engine in the living room, if it wasn't for the fact that we never use that room, and this is basically the only room not remodeled yet. Ugly indeed!

Thanks, and have fun installing your rockers and cams, plus timing.
I'm still in the process of waiting for my re-built rockers and pitted right cam to be repaired.

Are you using the rocker shaft seals?

Mike.

I must have stopped and removed the guide more than twenty times to check my work and vacuum the metal shavings out. I still need to run a tap down the hole to clean up the threads, but am going to wait until I have the heads off and have easier access.

Progress was slow this weekend with holiday activities and schlepping a xmas tree back to the house, plus all the lights. I did manage to complete the drilling, removed the fan shroud and took one of the chain covers off, but that's it. I am doing a lot of cleaning as I go, which is also slowing me down.

I've always wanted a reverse drill set for these jobs.. I've hear 8 x out of 10 the stud will come out as you are drilling it.

"I've always wanted a reverse drill set for these jobs.. I've hear 8 x out of 10 the stud will come out as you are drilling it."

Sound very possible. I wish I had thought about reverse drilling at the time. It's still a delicate procedure, but if the stud came out half way through the drilling, it would been much cleaner and easier to complete the removal.

Cam timing question. It took me a few hours to get comfortable with the process, but I am pretty confident I got it correct. Here is my question. The rebuild books states on page 166, column 1, paragraph 2, last sentence, "The dial indicator should reach it's desired value just before the "Z1 mark is lined up with the case parting line."

I did not experience this. I had to turn past Z1 to reach the desired value, then pull the cam pin and turn the crank counter-clockwise to Z1. I assume the difference is because of the exact starting position of the cam. Had I been one or two degrees further in the rotation, I would have reached the desired value prior to Z1.

I have double and triple checked my work and am getting consistent values in spec. Plus, I verified that 1 and 4 are opposite each other. Does this sound accurate? Is there some anal retentive step to quad check? Thanks.http://forums.pelicanparts.com/uploa...1269114018.jpg

gregwils 03-20-2010 11:53 AM

I have one more question if anyone makes it this far into my post. As I rotate the engine by hand, the right side chain seems to creak or make a slight binding noise at one specific location. The tensioners are not in the car, the idler arm is held by a C-clamp as in the above picture. You can hear the noise, but there is no physical resistance - nothing you can feel in the breaker bar on the pulley.

Any thoughts?

gregwils 03-20-2010 12:52 PM

I found the source of my chain noise. It definitely is an alignment issue between the chain and the cam sprocket. I measured the sprocket alignment, but didn't have the Stomski tool, so used a straight edge. The idler sprocket and the cam sprocket misalignment are causing the noise. You can also see the chain is not lying on the chain guard correctly. It's riding high on the ribs.

I don't get it, nothing changed. I didn't even have any work done on my cams and I reinstalled with the exact washers that were removed. Oh, well. I need to stop and disassemble a little. It would be a huge error to continue.

Make room, idiot at work here. Right sprocket on backwards. Thank you Cgarr. I left Craig a voicemail and he was kink enough to call and PM me.

BTW - I never publicly thanked him for the beautiful job he did on my heads. I sent them to him looking really bad and they returned like new. Guides were completely toast, intakes were bad too. He does quality work, quickly and at an extremely fair price. If I forgot to mention he was honest, he is honest too. There are a lot of great service providers on the board, but Craig's a great guy. Highly recommend him, search on cgarr.

88-diamondblue 03-20-2010 02:21 PM

Good catch Cgarr.

After I had everything put back together I was reading about the cam sprockets and PANIC set in of course it was 1 AM and wasn't going to be able to sleep. Thought I had put one on wrong. I took a huge amount of pictures both on tear down and during the rebuild. Started looking through my pictures and low and behold they were on correctly. Take pictures of everything going back together just for "peace of mind".:cool:

Just spin the crank another 720 degrees back to Z1 and verify that your dial indicator still has the correct reading. My cams did the same thing, I didn't get the correct movement until after Z1 so I ended up removing the pin and just leaving the crank on Z1 and rotating the cam backwards until it hit the mark. I noticed when I set the timing on a 2.7 it worked exactly like Wayne describes in the book but when I set SC cams I saw the same thing you did.

gregwils 03-27-2010 05:07 PM

I rechecked the timing this morning, a week later, as a final check. 1.24 on the 123 bank and 1.18 on the 456 bank, so I declared victory and moved on. Chain covers and cam lines are all installed. Rockers and valve covers next, then I will be sealed up.

I am still plugging away. I was lacking a tool that gave me clearance to torque the rockers. I found the answer from my friend Search - I'm good now. Ordered one of these and will use it and a 1/4 universal connected to a 3/8 adapter and my 3/8 torque wrench. Won't be perfect, but better than guessing....I guess.

Also, sent my injectors to WitchHunter. I mailed them via the good ole' post office on Thursday before Easter, the 1st. I got them back on Wednesday the 7th. I'm in PA and they are in Washington state. I was really impressed with the turn-around. I don't see how they had them more the 24 hours. I posted my results.

Greg,
I'm getting my heads back early next week so I wanted to brush up on any posts on the topic and found yours. (Nice work my friend!!!)
I will be excited to see your completed project...so get crackin!!! LOL
I've included a handful of pics of my own project (82 911SC 3.0) for your enjoyment.
Needless to say my project is in your "Rear View Mirror"....good luck!

Final Photo is just a teaser of my cleaning efforts...
I'll share more when I catch up to you.

gregwils 04-11-2010 02:25 PM

Thanks for sharing. It looks like you are moving right along. Your pace is probably faster than mine. I was only able to get about eight hours in this weekend, but I am really getting close to the end. I got the rocker shafts torqued and adjusted my valves, then got the intake back on the car. I need to finish up the fuel rails/lines/injectors, sheet metal, blower and a few other items. My goal for next weekend is to get the engine off the stand and mated with the transmission. I really hope this car starts and runs.

Truly an inspiring thread. I plan on the same task this winter. Keep up the good work.

Greg, love the polished fan, most I do is glass bead it and clean um up. Looks like spring is on the way in, in P-burg.

gregwils 04-13-2010 05:30 PM

I actually polished the fan by hand with fine sand paper and some steel wool. Fan treatment (paint, clear, etc) is almost a religion. I ended up buying some Gibbs and treating coating it a dozen different times.

gregwils 04-17-2010 06:18 PM

I have be close the 200 hour mark at this point. Lots of small items to address, and it seems like always one more thing to clean. Injection system, sheet metal, fuel lines, etc completed today. I am really close, maybe another half-day, then attach the transmission.

I NEED to finish. I have a host of other projects starting to pile up, plus my yard is calling me. I really hope I get a shot at starting it next weekend.
