Are Vec and Astra Engine Covers Interchangeable?

Thanks in advance :thumbup:

MikeS

yes

BURT150

Only thing different i think is the vec runs the p/s pump off the inlet cam and the astra has an electric p/s pump.

wot they said....

Cheers, so would it require any modification to fit or just pop straight on?

Is it just the Mk4 astra ones that fit or are the Mk5's the same also - Anyone any pics? cheers..

Not on the Vec C, the pump's electric.

and only one fuel line due to static fuel pressure and high pressure fuel pump

No HP pump on mine and lee's mike, thats the Z22YH, ours are still Z22SE's. Vec changed to YH's on a 54 plate, although all Estates and Signums have the YH from launch.

Trust me mate, when a Vec C pump goes you really do not want to know, and they do go, i've had 2, both under warranty fortunately.

Yea the rail is different, only one port, no return, I believe the Reg is in/by the tank. From what Vid mentioned when he fitted his 2.4 manifold he didnt need a take off for the FPR in this thread.

aye just like the corsa c and Astra G

when they fail it gets expensive

btw i do like the black cam covers

do they warp ?

rushy

I've not heard of them warping in the C. Only the 52plate Vec C was fitted with the ally one, all others including the YH have the plastic one. However I believe on guy on here (pos a VX220) said his warped. The Vec C has a big old bay so maybe it keeps cooler under there.
