I ve run out of luck down at the steelership...
Been chasing a whistling noise from under the hood
The vacuum tube had perished and turned to sponge so that has been replaced, but now the crankcase breather valve is letting air in (tried cleaning it but seems it needs replacing) and there is still a whistling noise that stops when the engine is under load.
I have removed the icv a couple of times and cleaned and oiled it but not helped. Perhaps this is shot and needs replacing too?
Cant find any other holes in hoses or bellows.
Replaced the gaskets on the TB and induction flange. Replaced ac belt (cracked), replace water pump (was still good) and pulley guide and tensioner (both good still) but the noise remains...
Steeler is doing well out of this one but has no idea what is the problem.
Any ideas before I run out of $$ and the misses murders me?
