Evening all.

I am going to view a car with a forged engine.

When I take it for a test drive, what sounds should I be listening for and under what conditions, to let me know the engine is fine?

For a short period after the engine is first started I might expect a bit of slap until temp is reached, but other than that should the engine sound any different to non forged?

Thanks,

Should only hear slap on tickover & is loudest when cold,some still do it when warm if running a big piston to bore clearance for big power & high boost. Take it up to 2500 RPM & it should sound sweet with no knocks or noises atall.

+1 above a little slap/tap on tickover is quite normal but not once the rev's are picked up.
Forged ej motors are quite renowned for being a little noisey to say the least lol.

best advice is, take a mate or pay someone who knows something about these. your a fool otherwise.......

Tbho that is very sound advice given there isn't much difference between normal forged noises and the start of something bad.

If its any good I will look for someone off here close to the car and slip them a few notes. thanks

Go look at it if in any doubt about anything ask the seller to go with you to your local Scooby specialist for a pre sale check over at your expense. Small price to pay for peace of mind & if he's a genuine seller with a good car he won't mind.

Another good point. A genuine seller wont mind at all!

As already said piston noise is normal even on forged Sti pistons, a slight tapping sound that dies down after a couple of minutes.

also depends on the make of piston, as some are louder than other makes
