I have a 2003 cab 100K Kilometres
just got home from work, about to turn off the engine when I noticed a clankitty clank sound from the engine, No check engine warning / no loss in performance
No drop in oil pressure/
Sounds mechanical thou

 

I had this about 4 months ago, got it trailered to the dealer and it turned out to be a hydraulic valve that dumped its oil, and pumped back up after he engine ran for a few mins. However a big chat to mechanic alerted me to a few things:
1. When the IMS go on the motorway, by the time you get off the road the engine is lunched
2. They have had them go noisy like this with no load on engine and salvaged the engine
3. Not starting it and trailering to the dealer is the right way to go, not starting it etc

 

Thanks for the reply.
That is my plan on Monday to have it trailered to the garage.
And to think I was going to do the IMS solution soon

 

Waterpump?

 

I hope so rruben

 

Let us know. Good luck.

 

Good luck with everything ermed911 and keep us posted on what it was.

 

any news?

 

waterpump, happened to me. Don't drive it

 

Finally, i got it trailered to the garage and yep it is just the waterpump. Whew!!!
Im getting the IMS solution.

 

Glad to know. Thanks for the reply.

 

Good to hear.

 

Just curious, was the sound only present at idle or was it clanking at all rpms?

 

Just going through this tread, I knew by the symptoms it was the water pump. My 04 did the same a few months ago. IMS is a very rare failure on the 03-04 cars. Let us know when you do get around to doing the IMS what kinda shape it's in. IMHO there are a lot of IMS being replaced out there that are perfectly fine.

 

It was present at all rpms
