I've heard noisy water pumps before & yes they can get loud. Hard to diagnose a noise an ocean away though.

 

:cornut: I can't help you so I'll just 'bump' you and keep you near the top until one of our mechanical gurus comes along. GOOD LUCK!

the R53 CAN have a timing chain tensioner issue (know from experience) and it is oil-pressure controlled so it MIGHT have been your problem. But if your oil pressure is now normal and you still hear the noise the tensioner might have gone. If you replace the "usual" one and still hear the noise - check the other side. (you'd have to ask Way of Way Motor Works if you want more details than that...)

 

There is a screw plug on the rear of the housing containing the timing chain, beside the oil filter housing. The chain tensioner is under this plug. Parts 6 & 7 below:



This is on the far passenger end of the block, where the belt is, etc. The plug is down low, to the right (passenger) side of the oil filter housing. You can't see it from the top side, but you can reach down and feel it. You can most easily access it by removing the wheel well liner. Just did mine this past weekend.

 

Well that's just retarded.

:devil:

 

If I wasn't using my phone standing in some ones garage I'd go to realoem.com and look up the info. It's in the engine section for an R50.

I'd even hazard to guess some one will do just that and post a picture of how the assembly along with the part number.

Wishing you luck

 

I don't understand why a bad water pump would cause all of that sound though... are you sure this is a reputable mechanic?

 

Sorry to say, but the damage has been done. No oil kills engines. You may get lucky & find it is only one part that has been damaged, very slim chance. Good luck. :fingerscrossed:

 

Yes the 02 Cooper timing chain & MCS timing chain are the same. At least they look that way to me. How many miles on your wife's Cooper?

 

:cornut: Correct me if I'm wrong but the R50-52-53(Pentagon/Tritec engines) didn't have the 'dreaded timing chain oiler failure' and subsequent timing chain failure with eventual total engine failure. This problem was on the R56 Turbo Charged(Prince engine) of which you don't have(but I do and had to have it replaced under warranty. Margi is an 08 R56 BRG MCS/JCWm).

Not to be a downer, but lack of oil could cause scoring of the tensioner leading to it not working as it should.
