I went to a new Jaguar place today called Dave's Import Service. I talked with Dave and let me tell you I now a new place to go for questions! That guy knows his shit. I started with a question about my distributor shaft and was there about another half hour with so much stuff to remember I think that I forgot some. To begin...
Some of the studs have an un-threaded section at one end.
This is the bottom. There is an indention/hole for this in the bottom of the block. This will set into the hole when the stud is fully threaded into the block.
There is a definite order to where the studs go. Let me tell you I have four books on assembly and none of them cover this. They say there is a dowel stud and it needs to... WHATEVER that means. I have two engines that I have disassembled and they not only had the studs in upside down but not in the correct order. After speaking with Dave I moved the studs around and when they were in correctly they were all exactly the same height (except the four that need to be a little taller) They go in like this
This places the longer studs on the passenger side in the 1st, 2nd, 5th and 6th position from the front. The reason for this placement is to place the longer studs where the engine lift hooks will be as they are thicker than the normal washers and will have to support the engine while it is dangling from the hoist.
What can I say. Thank God I found out now. There are several other things Dave told me to do that I will do and report here.
