Engine Rattle
Hi Guys,
My car seems to have recently developed an engine rattle when starting from cold. It is only for a second after starting, but it isn't somthing i have noticed before.
It reminds me of the noise a car that has been sat for a long time makes when it is started, as there is not a drop of oil in the head.
Anyone elses car rattle on a cold start?
I also just had my cambelt changed at MRC, possibly related?
I have done a search of the forum, and i have seen that this has been talked about before, but not for a while, and with no definitive answer. Any developments on this subject?
Cheers
Simon
P.S. My oil level is fine (first thing i checked)

RE: Engine Rattle
hydraulic lifters being noisy while the oil pressure builds up? If it's that then it is probably normal
RE: Engine Rattle
sounds normal to me , especially now it is colder . Should only last a second or two until oil recirculates

Hi, the rattle you hear is the camshaft timing chain tensioners. With age the oil seals perish in the tensioners causing oil holding pressure to drop overnight, as the engine is started it takes a moment for oil pressure to build up in the tensioners to tension the timing chain correctly, causing the chain to rattle. Simples
What timing chain?

oil preesure
Correction , its a known fault by audi,theres a pressure relief valve in between the banks, this fails allowing all pressure to be released overnight,bitch to change ive lived with mine since purchase , still offputting.
RE: oil preesure
if it's any consolation, M5 V8 engines I've heard starting up from cold sound a lot worse than mine ...
RE: oil preesure
Yep, you are right they have chains just under the rocker covers.
If the tensioners go weak the chain will catch on the rocker cover itself.
