Thought i would post some pics of GNU and also show any new member that the vauxhall V6 engine is a nice looking engine :)

The old bag of s**t engine. The one that you hate Mark DTM :D

The new engine just after having the heads put back on.

She should be with a bit of luck as sweet as a nut :)

See .... you just leave it parked up for 5 minutes and someone goes and nicks the frikkin' engine :o

Must be near Bridgwater then. ;D

Just a note.....in the pics the crank is at TDC, it should be at 60 deg before TDC (or after) to get the pistons in a safe position before fitting the cams or you risk bending valves on cam insertion.
I note that engine has had slick 50 or some other additive in it (the gold colour is the give away)!
Also, clean the cams before fitting, its not good to have them lying on a work shop floor (just good practice) as it can damage the hardening and pickup abbrassive material :y
I notice the new engine is also a pre 98 one?
Where the heads from the new engine?
Are you fitting new exhaust manifold gaskets?
Looking good :y :y :)

the replacement oil cooler looks like a proffesional job ::)

Lol, there is no oil cooler still fitted in the lump that has been removed.
Should have also said, have you put a wipe of sealent (green) under the front cam bearings?

You can tell it was proffesional even though its not there ;D

Lol, the goo is in the right place :y
Might be worth degreasing the plate a bit more as well as the block next time (note how its left the imprint of the plate where as when its really well stuck it totally mullers the sealent on removal) :y

Only if you are using Tesco value oil.
Good oil does not need such witch craft!

Well said Mark. :y
I thought as much, I am following the advice of the forum and using Vx own and changeing every 3k which is tearly for me.

I personally hate the rather stuff, particularly when working on an engine which has had it in because it sticks to EVERYTHING.

My Brother got the use of a 4th hand 1600 Mk2 Cavalier years ago when he was working for a company, had been totally neglegted.
He got the go ahead to spend money and service it, new disk,pads, filters etc.
The car struggled to get up the hill past Greasbrough dumpit site (the Rotherham Lads will know what I mean) and more often than not he had to change into 2nd to get to the top (not really a steep hill at that) Anyway, he dropped some wynns oil flush in, had a run round, left it to drain for a couple of hours and filled it with some fully Synthetic Castrol or similar brand oil. He also put some slibk 50 in at the same time. No idea why he used both.
Results were far better starting in the morning, lot better Mpg, but the main thing was the car went up past the dumpit site easily in 3rd gear and occasionaly in 4th.
He reckoned the slick 50 was the biz. I said the full service and good quality oil probably made the main difference, plus new air filter. He said the brakes hadnt been binding or anyrhing, and the old air filter looked as new.
So to this day I could never say if the slick 50 made a difference to the engine or not, one way or annother there was big improvement with the car. Not bad for a car that had done over 300K even if it was the 4th engine. ;D ;D

Yep -- everything was cleaned before reassembly! Guess which professionally fitted oil cooler is going back on !!!
The heads are those from the "new" engine --- just took them off to renew gaskets, also put on new covers, and yes, new manifold gaskets -----using the modified gaskets for police use. All GM.
BTW the new engine came from a y2000 on a W plate with 88k on the clock.
Don't know about the slick stuff -- probably ok for clapped engines in bygone years --- but from now on this one is getting the real deal.

In which case its not the original as that has an early type oil pump (the shape is a give away plus the low position on the lower right cam belt idler, later ones are half way along the belt run). The tin oil filter is a dead give away as well.
I suspect the engine number will be below 08300418 so beware of this with the cambelt kit :y
I mentioned the heads because its important to match the T-vents in the heads to the oil pump.
Good move on the manifold gaskets, there not police specials by the way as the plods didn't have them fitted as standard, they are just an improved part which for some totally unknown reason never got fitted at the factory :(

Should have also said, have you put a wipe of sealent (green) under the front cam bearings?
It has had some sealent put in but was the green used for the old astra / cavalier 4pot engines :)

Which is absolutely the right stuff to use for a close tolerance metal to metal joint, top job :y

The cambelt kit has the EB in the main tensioner bracket.

Its an early pre 97.5 engine with the lower flow oil pump and early lifters then

So did the later ones just have 10 in the bracket
-
01 actualy.
Two key give aways for the later engine.
1) The lower tensioner on the right side is pretty much half way between the crank on number 4 cam sprocket (its very close to teh crank and mounted on the oil pump on the early ones)
2) Metal oil filter, the later ones have a paper element.
The change basically involved using a later higher flow oil pump, paper element oil filter, antibleed down followers (quieter but require a higher oil flow), different T-vents (these control the oil feed to the lifters and are the torx headed bolts you can see in the heads around the cam area), different crank sensor (worth noting as it will ahve the earlier type fitted!)
Plus a few other more minor mods.
These changes appeared in production around mid 1997 (hence 97.5!)

Trouble is with a lot of these vehicles that you never know what was original --- case in point GNU must be on engine 4 !!
Main thing is that the engine seems in good order and is practically being rebuilt with no shortcuts

Correct, thats the important thing :y
Just trying to point out what it is so you dont stumble over any hurdles on the way which cause grief ;)

Is the crank at TDC with no belt fitted and camshafts bolted down :-?
-
May I sudgest popping some new bushes on the antiroll bar (mounted to the subframe) whilst its off (£2.55 + VAT trade club two off 90445625)

Was not there when he put the heads on but i must say the guy who has rebuilt the engine and putting it back in used to work for the vauxhall garage in town and i think he was there over 30 years and he was the only one to work on the V6 when they come in as the rest of the workshop staff only wanted to service and not touch the V6 so i think its safe to say he knows what he is doing, well he has been looking after my omegas for a few years now and has never done me wrong :)

Good idea but i think he wants to get it all bolted back to the car tomorrow as he needs his ramp back to fit a gearbox in to a carisma (c**p car) but what sort of job is it when all back in place.

Inlet trunking and maybe rad out.....just stiffens up the roll a little

Always remember that past experience counts for nothing....it could have been 30 years of mistakes (can show you a few like that where Man Father works!)

Thanks mark. Holy Count i think a trip the vauxhall garage is on the cards tomorrow :y

Will nip down lunchtime -- got to pay the bill for the bits at the same time

Can I sudgest you also remove, check and clean the ABS connector whilst the engine is out....
Sorry, racking my brain to come up with little easy things to do whilst access is so good.

Don't think he'd actually do that -- however will bring it up in convo tomorrow -- just to make sure ;)

I wish I could get my hands on it and help......spent 2 hours this PM doing a full brake strip and service plus fluid change on a Corsa....not nearly as interesting!
To put it in a nut shell, the guy building that engine has committed a cardinal sin by not setting it 60 deg before or after TDC because as you fit the cams some of the valves open (there is no cam position where they are all shut!), you can only hope that none make contact with the cylinder at TDC (number 1 and 4 in this case)

Remember I am a mechanical moron :-[ ---- from which pic do we think that the cams were locked down with crank at TDC ?
-
Picture number 6, the inlet cams are fitted and the crank is at TDC.........
-
Hmmm --- will check that out on the 'morrow
-
Yes, the picture clearly shows the crank at TDC and the cams in......

Was I right then? ::)
I hadn't read the whole thread, at the time of posting.
I really don't mean to interfere or sound rude (last thing I'd want to do), I just can't see how cams can be bolted down fully with the crank at TDC and no belt or locking tools in place, without high risk of valve damage, - I always thought if you needed to do cam work or rotate them, it should be at 60deg BTDC - Eg, 4 o clock, so all the pistons are down in the bores, hence no contact possible..
I must say - I too leant that from Mark - when I was begging for advice on my first V6 rebuild three of four years ago! He's been an invaluable help to me 8-)
-
okie dokie -- I am told that when the cams were fitted it wasn't at TDC --- and the tool used when fitting and locking was this, which I am sure you will recognise:
(http://i7.photobucket.com/albums/y271/maddogmulgrew/P7230006.jpg)
Have read elsewhere if you use this you can't go wrong -- and when fitting cambelt, if anything is awry the kit would show it up as the bits wouldn't then fit in the right places.
HNO3 might be able to clarify this later .. but, bottom line, I am assured crank wasn't at TDC when the cams were fitted ----- naturally if the engine throws or bends anything it's down to the guy doing the rebuild (of which he is aware) and for him to correct
-
Just come in on this thread, where was it parked? Liverpool!!!! ;D ;D ;D
Hat's off to you it's big job you're undertaking.... it'll be great when all done :y :y

Well i now know that he was sent on every course that vauxhall ever did on the V6 so fingers crossed ;)

That makes no rather odds what so ever.....you dont move the crank until all the cams are fitted and set to the timing marks! The photo shows thats clearly not the case!
Whats that smell.......horse......sheep......pig......no, its bull shite!
