Hi everyone I hope someone can help out with this issue.
so I purchased a wrecked 2014 Jaguar XJR, it was hit in the frame rail, so had to remove the engine to replace the frame rail, no weld required everything held together by solid rivets and glue. Put the engine back in fired it up and runs a little rough, went to change the oil, removed the oil filter and it’s completely dry, no oil in the filter housing or filter. Changed oil ran it for about two minutes, removed the oil filter, the filter is as dry as I installed it. Fired up the engine with the filter housing off and no oil being pumped by the oil pump.
is this normal with Jaguars or is it a bad oil pump?

 

All oil has to flow through the oil filter before going into the engine, so this is not normal.

You can watch the breakdown videos of the 5.0L engines on YouTube to see the oil pump at the bottom of the engine. It is chain driven on the same chain that drives the fuel pumps.

 

Do not run your engine before you have found the issue. The bearings will be gone without oil = total engine destroy.

 

Just d

Just dropped the oil pan to find out that the oil/vacuum pump chain snapped. Car has just under 27k miles, any idea how this could have happened?
Anyone have any advice how to get a new chain installed?

 

You need to take the engine out and inspect everything. That chain snapping at such low mileage is more of a symptom of something bigger than the cause. There could be issues with the timing chains.

Hopefully the engine is not toast already from being run dry.

 

Good catch! Anytime you change the oil there should be oil puddled inside the oil filter housing. Your problem seems major? But what usually happens is there are check valves that can go bad. What this means is you get a few seconds of dry start which is not good.
Several people on the forum have had to fix this.

Hope you can figure out what went wrong.
