Well, since we have an MG in here...
When I got the Jag, had AC....with enough pulleys to make it almost impossible to change a belt (almost rubbing the radiator) and you couldn't see the "generator" under the compressor. Once I yanked the compressor, found a Lucas Alternator.
Forward portion of the console (that holds heater controls and radio) were GONE to allow HUGE under dash AC head unit. Radio mounted in vinyl covered wood in package tray, which meant the cowl vent hadn't been opened in decades.
Then I found the air cleaner mounts were homemade....and the bracket across the rear head bolts to attach the hose for the clutch was moved to the middle of the engine to mount the homemade air cleaner bracket to.
Then found out the original carbs were replaced with mismatched Mercedes Pontoon carbs. HUGE jets.
Then found the breaker plate in the distributor was brazed tight in three places so vacuum advance didn't work.
Fixed all that, gutless as all get out...figured okay,. 3,000 pound car with 2.4L probably is.
Head gasket leaking externally. No amount of anything to fix it. Very low oil pressure. Clutch shook so bad is shifted the rear view mirrors.
Pulled engine and trans.....they had never surfaced the flywheel.
Checked cam positions before pulling apart (and especially since I had previously found exhaust lash was right on, inlet was zero lash).
Both cams 30 degrees of crank advanced.
Pulled the head.
Inlet valves hitting pistons (and had been for decades). To get the engine to turn over, they had back the lash on inlet vales to zero.
Two valves.
Pistons marked, pulled the sump...three inches of solid sludge.
Found a cotter pin in the screen..and the pump was broken in the rotor. Dug more bent up cotter pins out of the sludge, flipped the engine over, there was not one cotter pin in any of the castellated rod nuts.
At least one cotter pin went through the screen and wedged in the oil pump breaking it.
Jags are numbered starting from the read. Factory numbers were right, but the moron and centre punched marks for one through six starting at the front (rods and mains).
Flywheel was on in the wrong holes, which meant the mark through the bell housing when used to set up the cams was...30 crank degrees off.
Oh, and when they pulled the head for THEIR rebuild, they missed the two studs and nuts into the top front of the timing chain cover and snapped the ears off.
Heli-arced, surfaced installed on the block when they decked it.
Honed, rings, pump, milled head, decked block, been running fine with all sorts of power.
That's the short version.
Except...the coil mounts on the front of the cylinder head.
Apparently they lost the brackets.
So, they found a longer coil wire, and screwed the coil to the inner wing, directly below (and almost touching) the metal and glass fuel filter bowl.
