In any event I put the head back on and because I had moved the camshafts, they needed to be re-timed. I carefully read the manual and bought one of those metal tools which you put on the notch of the camshaft so it is aligned the correct way. Keep in mind that this was early in my learning curve for Jaguars.
I was very careful and with the No. I completed the rest of the engine hook up and got in to start it, expecting that I would soon be proud of my efforts.
I can not begin to explain my horror when I heard this terrible metal clashing sound. I was dumbfounded. Again I checked everything and verified that the camshafts were properly set. Eventually I convinced myself that I must have been hearing things so I tried to start it again.
Again there was this horrible noise coming from the engine. Remember, I had been able to get the engine to run before, so there must have been some mistake in my reassembly. I subscribe to the Zen school of automobile repair which holds that if you look at something long enough, the answer will come to you.
It took several days of starring at the engine before I saw something that was not quite right. The lobes on both the intake and exhaust camshafts pointed the same direction, not withstanding my care in having the notches in their correct place.
I finally removed the exhaust camshaft and guess what? It wasn't an exhaust camshaft at all but a intake camshaft. Of course it would not run, the intake and exhaust valves were opening at the same time and running into each other.
For reasons at which I can not even speculate, the prior owner had removed the exhaust camshaft and replaced it with an intake camshaft. He had rotated this degrees when it was installed and the engine ran. I learned from this that the two camshafts are mirror images of each other. The engine will run all day quite nicely with two intake camshafts or even two exhaust camshafts if they are positioned correctly.
Just don't use the timing tool on the notches. You can time one the correct way and then position the other degrees from the first. I finally got the engine running but later decided it would be better to remove the head and replace the valves that had been striking each other.
I still wonder what possessed the prior owner to resort to using two intake camshafts. Don- I just have to ask this one, was the the flywheel also on deg.
There seems to be a lot of this strange " deg. Will old Jags cease to run at all, come the Millenia? Drive while you still can! Happy New Year, regards, John Morgan. All else being equal, I'd suggest that you're timed degrees out of phase crank with camshaft.
Try crossing the distributor wires swap two at a time across the distributor. If you have compression during cranking, you probably are firing the plugs at the top of the exhaust stroke instead of the compression stroke.
