quick question to kevin....are the 2.5 & 3.0l oil pumps the same do you know?
...just checked, they both come up with
 part/no. 9193203

Can't see why they wouldn't be, but I believe there was a change at some point during production that required a change in the T-vents in the head to give the right oil flow to the cams and lifters.

thats right, dont know when/year though.

[Kevin Wood]

Hmm, I know your right..  :-)

Do you want to sell your spare heads?

I reckon Ill change the oil pump too while Ive got it apart. Is it possible to do while the engine is still in the car?

I would say: Drop the sump, clean out any debris from the pickup strainer and have a quick look at a couple of the big end shells. This will tell you if there was a wholesale lack of lubrication.

If everything looks OK, I would say it's more than likely that it was a timing issue, so refurb / renew the heads, check / clean / replace the lifters and see how it goes.

I have removed and stripped the engine right down now, the oil was like treacle which starved and seized the top end. The oil pump, mains and bores are all OK, the big ends are just starting to show a little wear so Ill replace them while its apart.

One of the inlet cams hasn’t been able to turn as the tappets seized but the pulley wheel wanted to keep going and cracked the cam where it locates on the pin.

Unfortunately Vauxhall no longer carry cams for the X30XE. Does anyone know where I might be able to get an inlet cam (marked G8), or failing that suggest an alternative set of cams?

Cheers Phil

I have a set of 3.0 cams but unfortunately its not worth splitting them because the 2.5 boys like them as on upgrade

[Pip]

How much would you want for the full set?

[Pip]

Ive eventually started on the rebuild, replaced all the bottom end bearings, heads, cams and rings along a really good clean up.

But putting the cam pulleys back on this evening I notice they can go two ways, I am guessing that it doesn't matter which way but if someone can confirm, that would be great.

Also noticed the crank pulley for the cam belt has lost its locating notch on the inside. Can anyone help with a spare one?

Cheers
Phil.

Hi Phil.

The cams have locating pins so cam 1 is the drivers side exhaust cam, the 2 drivers side inlet 3 passenger side inlet and 4 passenger side exhaust

[Pip]

Thanks for that, Ill have to double check which one Ive fitted where, but whats was worrying me was the pulley will go on two ways too even though the holes in the pulley seem to be off set.

[Elite Pete]

Yeah but each slot has a number

[Kevin Wood]

This might be handy when re-fitting the cams:

[Pip]

Thats brilliant, thanks.
Now I know Ive got the cams in the right places, but that diagram will help me get them positioned right and the pulleys fitted.

Just what I needed, Ideal.

[Pip]

All sorted now, I hadn't seen the numbers stamped on the front of the pulleys as the washers were in the way, easy when you know how. 

[The Red Baron]

good to hear the rebuild is going good.

[Pip]

Unfortunately its come to a bit of a full stop now, Ive spent knocking on £800 on parts alone now, as well mostly finished doing a LPG conversion but can't get a front pulley :-( and not done enough posts yet to be able to list in the wanted section.
