Alfa156 18 TS

Hello - and help!

Hello all, I'm hoping this forum will provide me with some answers....not many alfa specialists in my neck of the woods

Anyway, here goes! I drive a 156 1.8 TS, supposedly with 144 bhp from the factory. It's done 60k and had a new cam belt fitted when i bought it 3 months ago.

Two things of concern:
1) There's a clatter from the front. Sounds like the calipers! If i drive on a rough surface like cobbles the rattle at the front is very noticeable, if i cover the brakes (press lightly) there's no noise at all. Worn guide bolts?

2) It feels like 100bhp much less 144! Pinks a little changing through the manual box and is very peaky! The cat is leaking a bit (hissing but no "big hole") and is the original from new. Could the cat be partially blocked causing the lack of power? It feels....strangled.

Any ideas welcome!

They ain't reliable, but don't ya just love 'em!

Hi OneFiveSix and welcome,

I dont have a 1.8 at the mo but maybe can shed some light on your ailments:

1 - The front end clatter could be caused by aftermarket pads that are slightly smaller than the OEM ones and therefore rattle in the caliper which would stop whilst you covered the brake, but also possibly worn guide bolts, simple test, jack up, wheel off, move pads up and down if they are fine attempt to move outer half of caliper about.

2. Had a similar problem on a V6 Mondy, the internals of the CAT had collapse causing too much back press hence strangling the engine. The hissing could be this back pressure escaping through a corroded/split seam.

Hope this helps

Phil

Hi Onefivesix. Welcome to AO.

If you're looking for an Alfa specialist in Lancashire you could try this place. I don't know if they do their own servicing but if not I'm fairly sure they'll have a local garage that looks after their cars.

Re: Hello - and help!

Thanks for the suggestions MJet! I also had a cat prob with my previous car which was would you believe a Mondy! haha! Guess I'll replace the cat anyway, i replaced the rest of the system, only the cat left and it looks pretty dire to say the least.

As for the brake info i'll invade my dads garage (god bless parents) and have a look-see.

I must say that compared to the mondy (a 2.0 GLX) the alfa feels far less powerful at the mo but on paper has at least 20bhp more. And also the brakes feel way biased to the front, almost like the rear discs are there for fancy. Are alfa front brakes notoriously severe?
