Cam Cover Hose Delete

[livewirevoodoo]

Why was the timing belt hose deleted?

Any negative ramifications of leaving it intact?

Part #s for relevant cap needed for delete?

Thanks.

Subject:
Venting of Toothed Belt Cover

Venting of the toothed belt cover has been changed. This change occurred in two stages:

Stage 1





The belt Cover Opening is closed off (Fig. 1) but the hose connecting the belt cover to the air cleaner is still installed.

From Engine Numbers:

46 J 00709 924S, 944 manual trans.
46 J 61729 924S, 944 auto trans.
45 J 01865 944 Turbo
47 J 01 159 944 Turbo S

Stage 2 -





The hose connecting the belt cover to the air cleaner is discontinued and a cap (Fig. 2) is installed on the air cleaner end.

From VIN Numbers:

94 KN451075 - 944
95 KN155059 - 944 Turbo

Repair Information





Two valve engines from Model Year "87" only can be modified by installing caps (Fig. 3) on the belt cover and the air cleaner.

Parts Information

PN 944 106 103 03 Cap for air filter and belt
cover 924S, 944. 944 Turbo belt cover only.

PN 944 106 103 00 Cap for air cleaner
(Turbo only).

Discard the hose previously connecting the belt cover to the air cleaner.





The rear part of the toothed belt cover PN 944 105 039 01, applicable to 87/88 models is superseded by belt cover PN 944 105 039 02. With this cover, the opening (Fig. 4) is closed off.

Important

When repairing, no attempt should be made to open the closure.

****

Im not 100% sure why this was done. I have heard its because of water can be kicked up by the belts and sucked into the intake.

So for a non-turbo I'd need two Part #s 944-106-103-03?
