Hi all, new to the forum, hoping somebody can help me find a soloution!

I have a subaru imprerza 1.6 GL FWD
Ive now got a heavy rattle when i start the car from cold and when you rev it hard. its a sharp bangy rattle, like tappets but much LOUDER!

To be honest its not making any difference to the car, it drives fine, if anything i can go faster, the book says 108mph, once the rattle occured ive actually had car to 125mph!

ive tried soloutions such has tappet oil soloutions etc, too no avail, ive also changed the oil and filter, nope still no go.....

so does anyone have a solution? parts for these are har to get hold of!

thanks alot
phil

 

I can't believe you've nicked my user name

 

Sounds like piston slap, Does it go or get less loud when the engine is hot ???

You start getting a loud, mechanical noise from your engine and you take it to 125mph! Hmmm.

well ive more posts than you lmao
this is my net username, small world!

atleast i can say

 

sounds like the common flat4 ening banging to me
big end bearings gone m8
but not wise to drive like this as you can do more damage

i may b wrong tho....hopefully for you.

right, when car starts it rattles (this is from cold) once hot and you turn car off then back on - its fine no rattle, but when you rev it on idle about 2500rpm it starts to rattle and gets louder as you rev higher.

sounds like tappets to me? as if it where bottom end surely i would loose power and it would constantly knock, knock, knock

How hard are these flat 4 engines to work on? to me it looks very hard and im not paying garage price as id rather get a new engine for around £350 and drop it in myself diy style. - thats if something has terribly gone wrong! (fingers crossed not)

 

Have you checked for loose/rotten exhaust heat shields ??

Dean

 

Check out the cambelt tensioner. Remove one of the cambelt covers and run the engine. The belt should appear smooth with no flapping.

i don't think its any of the above, i will check though because who knows! but to me it sounds defiantly tappets, very loud tappets!

 

Camshaft Fooked, Not very common, But generally through oil starvation, Could be a worn Shim !!

Dean

 

right i have spoke to a guy about getting new engine, says check crank shaft and oil pump? so check above, and also get nice and dirty taking sump off.

could be a possibility? maybe?

I can get the engine for £308 all in inc delivery.

 

also whats a shim lol

also ill be honest, car has had a very very good caining

 

Well if you have /are going to check the cheap & obvious then an engine (Assuming it's Ok) for £308 is Ok.

A shim, Is used to remove/create a measured gap/clearance/space etc,i.e for Tappets & cams amongst many others

on the serious note of an engine, what will fit straght in, would the 1.8 go in with out any modifcations to looms etc?
