I have got a very noticeable ticking/tapping noise coming from the engine of my 2003 LCR, but I have now reached the end of my diagnostic capability. If any one can give me any pointers of what to look at next it would be greatly appreciated.
Symptoms;
1. The noise sounds like it is coming from under the cam cover, at the chain end rather than the belt end.
2. The noise is definitely rev related - The higher the revs the faster the ticks/taps.
3. The noise came on quite suddenly, rather than got worse over time.
Most people that have heard it have said it sounds like tappets/followers.
Now through searching online, and throughout this forum I have I have uncovered that there is is a common problem with oil sludge. Unfortunately, over the last 4 weekends I have done all of the jobs that would normally fix the issue, and more..................... Help
I have-
It really does sound like the problem is lack of oil in the top of the cylinder head, but I am confused as to what could be causing it.
When the oil pump was off, I looked up the gallery in the block and it was nice and clean. I could see clearly up to the the point it goes off in another direction.
Does anyone know if there are any pipes or galleries that could reduce the oil flow, but which wouldn't set off any of the warning signs?
Could I be going in completely the wrong direction and have a problem somewhere else?
What else could I check?
Help anyone ! !

I have-
- Changed the Oil & Filter,
- Dropped the sump, cleaned it out, replaced the Oil Pick Up Pipe AND the Oil Pump,
- Taken all 20 Hydraulic followers out, fully stripped down/Cleaned/rebuilt them,
- Replaced the Timing Belt and Tensioner,
- Replace the Cam Chain Tensioner,
- Unplugged the Oil Pressure switch to make sure it was working - It was.
- Removed the Oil Pressure Switch at the Filter, and put a manual Gauge on it - It read 4 bar.
- Run the engine without the accessory belt - to eliminate the AC Compressor & Alternator from the equation - The noise was still there.
