Nasty engine rattle 1500 to 2500rpM

[asasprey]

When I bought the car I noticed there was no oil in it. It's go the usual injector tick but has a nasty metallic rattle from the engine. Its an embarrassing sound to say the least. I thought maybe big end bearings or downpipe or timing belt tensioners. I have put a full milltek on and the noise is still bloody there. Any ideas guys? I really don't want it to be bearings.

 

[asasprey]

The noise stops as soon as you come off the accelerator and the revs drop down.

If its as bad as you say it sounds like a piston has picked up or a big ends starting.
Does it not alter when pressing the clutch? They are common for release bearing chatter.
Just an idea.

 

[asasprey]

Will go and check!

 

[asasprey]

Was hoping it was the release bearing but no change

The rattle stops as soon as the turbo kicks in. I read somewhere that the 1.4tsi engines have problems with a clip on the wastegate :/

You had this car long ??? can you just take it back to the garage you got it from ???

Hate to sound arsy but why would you buy a car if it had no oil in it - doesn't exactly show its been treated well.

Best thing would be to have a Seat or a decent garage look at the car, should be able to tell you wroughly if the rattle is serious or not and worth investigating.

Did a private part ex with my Audi a3 a couple months ago, so no garage. The Audi was knackered and I just wanted rid. Only noticed no oil a week later to be honest. and I'm a technician for Subaru and have done big end bearings on a 2.0 turbo ej20 and it didn't sound like this, the Subaru was much louder and more of a knocking noise. Think I will get somebody to sit in it while I look underneath on the ramps.

Also heard of a brake pipe rattle? Seems possibly too loud though

Any lack of power? Smoke? Possible the turbos hanging out of it, could be worth taking the turbo intake of and checking the play ect on the shaft.

 

[asasprey]

No loss of power. Dyno'd 242hp. No smoke. No excessive mpg. At some point it looked like the alternator belt was rubbing on the air con pipes :/

 

[vincent5525]

Alt belt rubbing? Have you checked engine and gearbox mounts?

 

[gti_jones]

check the aux belt tensioner, does it rattle like mad? possible alternator pully fault

 

[cheungy]

Have you check the engine mounts? and also the subframe...bolts - Hard to tell without hearing...

This is for the TSI engine and not for the TFSI - please correct me if this is wrong
