RussB Posted November 12, 2006 Report Share Posted November 12, 2006 It's so shiney Getting that "130 degrees" is a real Mutha, huh? There's some serious torque on those bolts! :o Link to comment Share on other sites More sharing options...

Guest Guest Posted November 13, 2006 Report Share Posted November 13, 2006 It's so shiney Getting that "130 degrees" is a real Mutha, huh? There's some serious torque on those bolts! Thats why you do it in two steps, screw turning 130 degrees at once... thats no fun. I would do 50% one time around and then 50% another time around. This is a lot easyer and less stress on the bolts. I just did a VW eurovan that needed 180 degrees, i did 90 and 90 and it was still hard as h3ll.

Hilton Posted November 13, 2006 Author Report Share Posted November 13, 2006 thanks, I appreciate it.Yeah, we also did it in two steps. We did 90 and just less than 45 though. I torqued each bolt to 15. Then I came back to check them and a lot of them needed to be tightened up to 15. Then I did the same with the 44. I think I made 3 passes before all the bolts were at 44. Then I did each bolt to 90 degrees, then I finished with ~40 degrees more.Before I put the gasket in I sprayed it with 3 coats each side of the copper gasket spray. (use thin coats so it doesn't make a mess.)I stuck the lifters back in and I'm calling it for the evening. Now I have to make the decision whether or not to have the intake and cam cover/holder powdercoated. Part of me thinks it a waste of money, and that I could better spend the cash elsewhere. Another part thinks that it would be awesome to have the intake and cam cover match the hoses. If I hadn't spent so much money lately it would be an easy answer. I'll probably have it done. Blue looks nice.More pictures to follow. Link to comment Share on other sites More sharing options...
tca217 Posted November 13, 2006 Report Share Posted November 13, 2006 For something that looks real sharp, polish out the cover that covers the injectors, use a fine wire wheel with a air grinder or air drill and go over the intake and it will look bitchen. I did that to mine and it really stands out. For the cam cover, I just left mine black with the silver letters till I figure out what to do with it. The hardest part of all this was getting the clear coat finish off the aluminum injector cover. I just sand blasted mine then went over it with fine wet/dry sandpaper then polished it out by hand with some Mothers. No money and about 1 1/2 hours and it looks great.

Hilton Posted November 19, 2006 Author Report Share Posted November 19, 2006 I dropped off the upper portion of the head, the intake manifold, the two pieces of the upper engine brace, and the fuel injector cover to be powdercoated on Friday. I went with blue. Yesterday evening I was invited over to a friend's house to watch the Cowboy/Colts game tonight. That's when it struck me. (My Volvo is Silver) I'm going to have a Cowboy colored car. I QUICKLY need to find another team that has a silver/blue color scheme. I want something obscure, like curling. Any suggestions?I am very excited about getting the parts back though. It's going to be very cool. I'll post pictures Link to comment Share on other sites More sharing options...

So when you are going back again and again its over tightening the head, do one pass... i might be wrong but thats what ive always seen and heard.Anyway DAMN! those parts are shinny.... not bad at all...
