Subject: Re: New LTX running well but..... by rklessdriver on 2008/11/7 21:59:44 OK Well I finally got my new rocker covers all cut up and welded back together. Most important thing I needed to do was stop the oil leak from catching my car on fire everytime I tried to drive it farther than around the block... I made good use of my CDO day (love that Govt job) and kinda documented what needs to happen if you ever want to run these 18 degree style Moroso rocker covers on an LTX Corvette. First your going to need the specs to start cutting. Now mine had to clear the rocker stand on the inside which over hung the stud boss by about .250 and that made it real tight trying to clear the lower bout of the Alt body but these measurements got it done. The angle cut on the top half of the rocker cover is to clear the Alt brg support.

I used a cut off wheel and a die grinder. [IMG]http://i50.photobucket.com/albums/f303/rklessdriver/Corvette/Clif.jpg[/IMG] Start bending some sheet alum to patch up the hole and weld it all back together. You can see I tried to re use the part I cut off but in the end I had to just fabricate an entire new piece. [IMG]http://i50.photobucket.com/albums/f303/rklessdriver/Corvette/Clif1.jpg[/IMG] Installing them on the car. Because they are so much taller than the stock rocker covers and my previous Carbonfiber ones, I ran in to some interference with the Alt/AC compressor bracket. I had to grind the accessory bracket (quite a bit) to clear. [IMG]http://i50.photobucket.com/albums/f303/rklessdriver/Corvette/DSC00942.jpg[/IMG] Installation complete.

Before with the Carbonfiber rocker covers, I had to space the alt up about 1" to clear them. This presented a real problem the first time I got on the car on the street. The motor moved over and the Alt quickly chewed a nice little hole in my hood. These cut up Morosos allowed me to place the Alt back all the way down in the stock bracket and I didn't have to grind on the Alt body for clearance anywhere. As you can see plenty of clearance everywhere. [IMG]http://i50.photobucket.com/albums/f303/rklessdriver/Corvette/DSC00940.jpg[/IMG] While I had the rocker covers off I also re-adjusted the lifter pre load. I went from .020 (anout 1/4 turn) to .050 (3/4 turn). Morel seems to think this will quiet them down and put the plunger in a better position to retain the oil in the lifters plunger cavity and prevent them from bleeding down. More pre load is against everything I know about running hyd lifters but if that's what Morel says to do, I'm all for it. I have run the car to check for leaks (Thank GOD there are none) and the lifters are a bit quieter... Tomorrow... I need to drain and flush the fuel filled oil out. Also since my Alt is now back in the stock location I need to find a 68" belt (the stock 67" won't ever think about going on and the 69.5" I have is way too long) to put on it. Once that is accomplished I'll take it out from some test runs (on a closed course, naturally). Hopefully it will have a nice lean miss above 6000rpm. Will |
