What kind of engine did the Jaguar XJ40 have?
Later 3.6L AJ6 engines as used in the 1986–1989 XJ40 cars had a crank-sensor type of ignition system with a bare distributor that only carried the spinning ignition rotor inside the distributor cap. The fuel-injection system used on the later 3.6L AJ6 engines used a hot-wire Mass Air Flow sensor to determine engine load.
What’s the angle between the valves on a Jaguar AJ6?
The angle between the valves of the AJ6 engine is 47 degrees which leaves room to bring the head bolts up just inside the camshafts and through the camshaft bearings, making them readily accessible but at a price of complicating any repair work.
How long are the studs on a Jaguar engine block?
Replace all the long studs, 8. While being replaced, the studs will rum 16 to 17 turns into the block, allowing for the domed cylinder head nut to tighten onto the head and not torque up a few threads above the spacer. Four studs are slightly longer than the others; this is for the engine lifting brackets.
How often do you change spark plugs on a Jaguar XJS?
Spark plugs: Pre-HE engines, Champion N10Y or equivalent; HE engines, Champion BN5 or equivalent. Gap 0.025in. (0.64mm.). Check/clean plugs every 6000 miles (using brass-bristled brush); renew plugs regardless every 12,000 miles.ALWAYS blow dirt from the plug wells before unscrewing the plugs.

What was the original engine of the Jaguar XJ40?
The original engines were the DOHC 3.6 and the SOHC 2.9. The DOHC 3.6 was revised and enlarged to 4.0 in 1990. It is still essentially an “AJ6”, however. This was, as per usual, offered for the XJ-S before it was built into the XJ40 saloon. The 3.6 L (3,590 cc) was the first AJ6 engine, debuting in 1983 on the XJ-S.
How big is a 4 cylinder Jaguar engine?
For clarity, I used straight port XK Jaguar heads to compare with the later 24V head for now. The later 4V per cylinder Jaguar engines were a project of Spen King, as was the Triumph Dolomite. These engines all used a bore size around about the same 91-93mm.
When did the Jaguar AJ16 evolution come out?
It was only the third all-new engine ever designed by the company. The AJ16 evolution was replaced in 1996 with the Jaguar developed AJ-V8 engine . Jaguar had considered cutting their existing V12 in half to build a V6, or possibly a V8, but chose instead to develop a new inline six. The cylinders are inclined, as in a slant-6, by 22 degrees.
