Where are the camshafts located on a Jaguar?
This camshaft is pictured on the left side of the picture below. All three of the cams are exhaust side cams. When the timing mark is at the top, the first or front lobe points to the side of the engine it goes on. In 1968, Jaguar changed the lobe pattern of the camshafts.
What happens if the camshaft position sensor goes out?
Due to the lack of feedback information to the computer this sensor problem can cause an engine stumble or hesitation. Though some think the engine will not start if this sensor goes out but this is simply not true because the computer will always use the crankshaft angle sensor to allow the engine to run.
When did Jaguar change the lobe pattern of the camshafts?
When the timing mark is at the top, the first or front lobe points to the side of the engine it goes on. In 1968, Jaguar changed the lobe pattern of the camshafts. This was not an emission change but rather a change to smooth out the tappet noise. The lobe engaged the tappet more gently rather than slapping.
How much does it cost to replace a camshaft sensor?
Camshaft Position Sensor Replacement Cost. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200. Labor costs will be in the range of $70 to $100 for professional replacement.
Can a bad camshaft sensor shut down an engine?
Without this information, the engine would not be able to function properly. Over time, the camshaft position sensor can fail, or become worn down, due to accidents or normal wear and tear. There are a few warning signs to watch out for before your camshaft position sensor completely fails and shuts down the engine, making replacement a necessity.

Why is my Jaguar XJ engine not working?
Supercharger replacement due to loud bearing whine. Both knock sensors replaced due to error code. Changed the under-supercharger water hose at the same time since the supercharger needs to come out to replace the knock sensors. All other water hoses that were difficult to reach also changed.
Where does the camshaft position sensor send the information?
The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM).
What’s the valve size on a georgiajag camshaft?
The standard valve adjustment is specified as .004″ on the intake side and .006″ on the exhaust side. If you are adjusting them and cannot get them right on the specs, it is better to error on the wide side. High performance use specifies up to .010″. For street use, this just makes a lot of noise.
What kind of Cams does a 1957 JAG have?
First, keep in mind that although the car is a 140, the engine is a 1957 MK1 #KE-1610-8. Also, before I took the head apart, it ran very nice with the cams it has, right or wrong. Here is the strangeness. My cams have these numbers: intake-MC20889-E (in the casting) and C1308? (stamped) exhaust- MC20889?

What are the cam clearances on a XKE V12?
The XKE V12 had valve clearances of .014-.016. The same cams went into the XJ12 and XJS with specs of .012-.014. From there they went into the HE engines with clearances of .010-.012. As on the later 6 cylinder cars, adjusting on the wide side helps smooth out the idle and engine vacuum.
