Bye Bye Clicking Sound..A Slow'N'Rusty Pictorial - BOV Housing

[timspu]

Brilliant, always wondered what that clicking was when the throttle pedal pushed at Idle, another job to be done. Awesome right up. Thanks

just use the german method of goodntight. They are small fasteners so say 8-10 ftlbs.


I did this a month or 2 ago. I tried to be clever and avoid taking off too much stuff and I was struggling. Then I just decided to take off anything in my way and it was straight forward.

I ended up using a little permatex anti-sieze lubricant. The silver stuff... I guess it'll be fine.

Good stuff - thanks for posting (even if my car doesn't have one of those) but just a nitpicky tid bit of info -
BOV = Blow Off Valve - i.e. vents to atmosphere when you lift - and makes loud whooshing and hissing sounds - Fast & the Furious stuff. Typically aftermarket.
BPV = ByPass Valve - recirculates [metered] air back into the intake tract when you lift. This is what we have - and pretty much any factory setup from any manufacturer.

Not a big deal [obviously] just saying....

Yasin,

and for more years to come I am sure. I am going to order the seals as I do not think this has ever been serviced. After 35yrs I am sure it is due.

Thank you for this thread and the write up. I have had this problem for the past few years...

Now I am going to take a Saturday afternoon and fix that pesky noise!!!!

So, whats the downside if you dont change them ?? Do you lose something ?

[mooney265]

Metal constantly hammering Fragile Cast Magnesium [I think] Metal... So, probably not a good idea long-term... But, if you don't decelerate too often, then it wouldn't make much of a difference...

somebody should make these out of brass or copper and sell them to 930 owners. You could make millions, er thousands.......of pennies. I think a soft metal gasket would work better in this application and you wouldent have to replace it every decade or so.

Hi,

I am wondering if the clicking sound you were hearing is the same as my 1978 has just developed.
It's a clicking tick kind of sound when you hit the throttle. more noticeable at low revs but you can still hear when you throttle at higher revs.
If it is indeed this sound then would you be free to have a bit more of chat on your pictures. I'm not quite clear on some of them.
It seems your approach is quite straight forward though.

Kind Regards
Deryck
