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  

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

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?

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

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  

Just trying to point out what it is so you dont stumble over any hurdles on the way which cause grief

All and any advice is much appreciated

Is the crank at TDC with no belt fitted and camshafts bolted down  :-?

[Marks DTM Calib]

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
