Ebized Posted January 8, 2016 Share Posted January 8, 2016 Video compiling as I type this. I think I may have sussed the issue. I think it is the exhaust. The video I'm posting shows Idling from a cold start, Idling when warm, Switching on Air Con, Gentle revving and idle - all of which sound perfect with no noise issues. The final part of the clip is after a short run in the car. The noise can then be heard clearly. While I was looking I dropped my keys on the floor. When I bent down to pick them up I could hear the noise more clearly from under the car so I got underneath and it was much louder there, which leads me to think it is the exhaust. Any thoughts ? Can't see how to embed youtube clips so, Video Link - https://www.youtube....eature=youtu.be Thanks everyone.

Ebized Posted January 8, 2016 Share Posted January 8, 2016 To me it sounds pretty normal from my days with the 370 - maybe with the idling a tad on the low side. The engines are not exactly renowned for quiet running at either end of the rev range. 1 Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted January 8, 2016 Author Share Posted January 8, 2016 (edited) That's the annoying thing. It sounds absolutely great to me as soon as I drive it. It's only when idling that the noise occurs... I've just filled in the contact form on Cougar Stores site asking about getting it checked. Is it a mammoth job to identify if it is the gallery gaskets ? (on a side note, anyone else suffer from missing letters when replying on here using Internet Explorer 11? It is fine in chrome ??)

Jack Carter Posted January 8, 2016 Author Share Posted January 8, 2016 (edited) If it is the gaskets, I'm staring at £800 for the job it seems... Does that sound about right ? Edited January 8, 2016 by Jack Carter Quote Link to comment Share on other sites More sharing options...

laytonanthony Posted January 9, 2016 Share Posted January 9, 2016 Can't see it being oil gallery gaskets. You would get low oil pressure codes. Quote Link to comment Share on other sites More sharing options...
laytonanthony Posted January 9, 2016 Share Posted January 9, 2016 (edited) Also as soon as the car detects low oil pressure, 1. You will get engine management light. 2. Obviously a code. 3. The car will go into limp mode to prevent further damage. I'm 99.9% certain your oil gallery gaskets are fine. I'm assuming all oil levels are fine?

Jack Carter Posted January 9, 2016 Author Share Posted January 9, 2016 Hi mate, Yes, all oil levels are perfect, no engine management lights, no code, no limp mode, nothing. From what you've said, I more inclined to think it's exhaust related. Cheers Leytonanthony. Quote Link to comment Share on other sites More sharing options...
Richf Posted January 9, 2016 Share Posted January 9, 2016 Could be exhaust its hard to tell like this but as 1.49 and 1.50 it doesnt sound like exhaust to me Quote Link to comment Share on other sites More sharing options...

Out of interest how does the car detect low oil temperature ? Playing around with logging software I cant find a pressure sensor on the engine Quote Link to comment Share on other sites More sharing options...
laytonanthony Posted January 9, 2016 Share Posted January 9, 2016 Dual mass Flywheel maybe? Early stages they will get a slight knock? Mine had gone on mine that gad done 36k. Quote Link to comment Share on other sites More sharing options...
OllyB Posted January 9, 2016 Share Posted January 9, 2016 (edited) My hr 350 sounded like that when the bearing went on my top idler pulley, they to locate the noise using the good old ear and screwdriver techneique.

Jack Carter Posted January 9, 2016 Author Share Posted January 9, 2016 Would that sound louder under the car ? Quote Link to comment Share on other sites More sharing options...
OllyB Posted January 9, 2016 Share Posted January 9, 2016 I guess it would be if it was a lower pulley. Was the bonnet shut when it sounded louder underneath. Was the noise more to the front or rear of the engine bay? Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted January 9, 2016 Author Share Posted January 9, 2016 No. The bonnet was open. To my ears, it sounds at the back of the engine bay. Quote Link to comment Share on other sites More sharing options...

Its an auto according to the first post , could be the flex plate but then it could be a lot of things thats why it needs checking hands on Edited January 9, 2016 by Richf 1 Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 9, 2016 Share Posted January 9, 2016 Doesn't sound that bad to me, they are noisy engines, the cam and injector noise can be amplified by the large amount of alloy in the engine, Didn't the OP mention putting it in park so I would presume its auto? th gallery gaskets wont be a cause, apart from the fact that the oil pressure is already low at idle, unless there was a serious lack of oil you wont hear it from the engine, aside from CEL etc. 1 Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted January 9, 2016 Author Share Posted January 9, 2016 Checked and double checked the oil level today and it is spot on. No loss at all. What is CEL? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 9, 2016 Share Posted January 9, 2016 CEL = check engine light. 1 Quote Link to comment Share on other sites More sharing options...
