Naff, I think you've been sitting on your board too long - the ocean has got in and your brain is rusting.

As for that sound almost all subaru flat fours with a few kays on them do it when they are cold, my NA 92 legacy does it when it is cold. Forged pistons are not the cause. Largely differing rates of thermal expansion of internal parts would be the death of many engines so I doubt that is the case, the piston rings are going to expand first anyway. The only legacy I know of that comes with balanced forged pistons is the STI S401. I am pretty sure it will be bad lubrication of the lifters which is sorted once the oil is warmed and had its viscosity reduced.

It disappears when the engine reaches normal operating temperature, and so is consistent with higher piston to bore clearance required when forged pistons are fitted (forged pistons have a higher thermal expansion rate than cast).


Interesting. I would have thought the forged pistons would first be cast into a rough shape. But hey who knows what corners they've cut. I haven't noticed it in my brothers B4, how many k's on yours? Is it the result of bigger clearance and a bit of wear?

I know my rangies diesel is a whole lot quieter, better and sweeter with a new thermostat, it was running about 10-15C too cold. Apparently diesel pistons have ceramic fibres in them to keep the expansion down.

I've heard of the chev/holden LS1's having major slap issues and drinking oil because of it.

I had a WRX in the UK and it was making slapping noises when cold. So I took it to the dealer and they said that the engine was buggered coz the cylinders were ovalised (nothing to do with the way I used to drive it I'm sure...).

They gave me a new engine too, which was pretty nice of them, and fitted it too. Don't you just love manufacturers warranties? :)

I went with work to the display yesterday down regent Street. It was VERY loud and gave the punters what they wanted - burnouts & doughnuts. Accessability was the key.250,000 people watching after work. Regent street/PiccadillyCircus is about the same length as Lambton quay. Renault didn't even have a car on this stunt and we had a cool after party in Air Street. The Jordan party must have rocked too.
Oh and a quick note - Mansell stalled the Jordan.

Ha ha :D

.... but in his defence, the clutch on a F1 car is small as (about the size of your fist) and an action like a light switch. Stalling is very easy to do.
