WRX Rattle/tin can noise

[sideburns66]

Hey guys, pretty new here as I'm a proud new owner of a WRX ;D

However just noticed a couple of things which are naturally getting me pretty worried..

It's done pretty high k's as well so any help would be appreciated - I didn't notice these things when I tested it.

1 - at around 1700-2000 rpm and also about 1000 I sometimes hear a bit of a rattle - almost sounds like shaking a little nail in a tin can or like there's something loose? Not the best thing you want to hear coming from your engine - doesn't matter whether I'm accelerating or decellerating seems to do it at these rpm ranges - maybe others but haven't really noticed anything.

2 - when the engine's warm I've noticed a faint ticking when idling and I stand outside the car - I guess this could be anything/it's quite common?

If anyone's in the Chch area and would like to come have a look or could recommend me anywhere I'd really appreciate it - I've been to Crowesport the other week to do my rocker covers and header tank but they really screwed me round and ripped me off so dont really wanna go there again..

Thanks!

Try Stubaru , they know there stuff. welcome to club sub though, good to see another chch member. that faint ticking noise is normal for subarus , without hearing it ofcourse. the nail in the can noise , guessing an exhaust sheild is rattleing.

Yeah was thinking stubaru. Thanks for your reply, makes me feel a little better as well!

The rattle could well be a heat shield... I know my rs has a faint rattle at 1150rpm Which is the heat shield.

The tick could just be lifters.. If it is quiet i would not worry too much..

Do an oil change and go from there

if its a v1 or 2 it could be lifter noise - engine flush then oil change is allways good for cleaning lifters - or it could just be injectors ticking away

[sideburns66]

Yeah the tick is reasonably quiet, you can just hear it if you're outside the car and close to the bonnet. With oil change - would you suggest synthetic?? And how about weight etc? I'll get that rattle looked at this week

[WRXONP]

ive never ever had any good experience with any fully synthetic motor - it gets through valve seals allot easier than a mineral oil for some reason

i use valvoline VR-1 its a syntheticly enhanced oil not a fully synthetic

my vote is an exhaust heat sheild, its very common for the heat shield around the up pipe to come away.

and oh boy I love a good oil discussion!!! my vote for anything older than version 6 (i.e no avcs) is castrol edge 10w60

basically anything 10w40 and above and at least semi synthetic, I wouldn't go as low as 10w30 on an older high km engine.

What do u recomend for avcs engine and y?

I have ways used magnetec 10w40 on all my cars with 4000km changes

Yea always good to see oil discussions

Jump in the car, open your door and sort of hang your head around the bottom of the car and give it a little rev. Could be a bit of rust or something in the exhaust. Had the same sort of issue with the girlfriend's E36, turns out on that one of the mufflers had been removed.

I was just staying away from commenting on anything AVCS as some people say running higher than 10w30 effects the AVCS. I've ogt a mate whos always run edge 10w60 on his 238kw v7 sti with no drama though
