Hi

Is it easier to change the manifolds and gaskets by removing the engine? Dont want to disturb the head gaskets by doing it the usual way. Was thinking of changing my clutch at the same time.

my local mechanic friend and I had thought of dropping th engiine and box downward along with the front subframe for ease, any views on this method?

cheers

If you ask the stealers they insist on taking it out..

I'm sure I have seen a thread on here that said you can sort these out without removing the engine at all...but dont quote me on that just yet lol

If your talking about a V6 you can change the nearside one insitu the offside one can be done by lifting the engine off it's mountings and swinging it to the nearside whilst that manifold is off, it is a bit of a fiddle but it can be done. Make sure you have new Vx studs and nuts and use Vx gaskets as well.

V6 driver's side can be done in situ, I haven't tried the passenger's side but others say it can be done with difficulty.

I do not see how the engine could be removed from below.
Subframe?

Hi,

yup sorry should have mentioned its a v6, I am planning on getting the manifolds skimmed as Im almost certain they are warped as the gaskets were replaced 3 years ago, could be that non genuine gaskets were used, Im not sure as I wasnt the owner then, and the reciepts dont say if genuine parts were used.

cheers

Doing it the usual way you will not disturb the head gaskets..

Only takes time.

I recently broke a v6 for spares and when we removed the engine we left it attached to the front suspension setup, all we had to do was raise the shell and roll it back away from the engine etc. was really easy, altho did require disconnecting engine wiring block and strut tops. I had planned on doing this same method to transplant the engine and box from an elite I have into a mint 2.0 shell, saves splitting the box and exhaust downpipes from the manifolds.

As Vauxfan...have done the same on a Cavalier, undo the subframe bolts and various other bits and voila!!

Drivers side can be one in situ.

Passenger side you support the engine, remove the drivers side engine mount nad un-bolt the passenger side one. Ease the engine over an inch or so and you can now get access.

The passenger side one is actual quicker to do given an engine support!

As for the manifolds, never seen any major warping, you do get a slight twist but, nothing like the 4 pots.

I ahev seen police ones cracked slightly

Perhaps when it was done last they used the naff aftermarket composite ones rather than the upgraded multilayer metal Vx ones.

Now been round all my local garages and after explaining what needs done and how to do it, they have all refused to take it on. Im a fairly competent diy mechanic but eben I dont want to tackle this on my own especially since I dont have an engine support readily available.
