Got a high mileage 1989. 944 Turbo.
Done over 230k miles.
Newish turbo.
Gets up and goes above 3000rpm
But doesn't feel like 250bhp anymore. Lol.
It is running 20/50 oil.
Cold starts at 4bar.
Runs at 3bar when warm above 2500rpm.
But when hot, sat in traffic, on tick-over, it drops down to 1bar.
So, what do you experts think.
Is there a possible easy solution? (Weak pressure by-pass valve?) Or engine rebuild before more serious damage?
Thanks in advance.
