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

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

Well, hes done that wrong!

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!)

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)[/quote]

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

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

[HolyCount]

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.

Please dont say sorry as all the help you can give is great and one day we hope that we will meet and buy you a drink

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

Just the one ??    Several methinks

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 ?

[Marks DTM Calib]

Picture number 6, the inlet cams are fitted and the crank is at TDC.........

[HolyCount]

Hmmm --- will check that out on the 'morrow

[Marks DTM Calib]

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-)

[HolyCount]

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:



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!!!!


Hat's off to you it's big job you're undertaking....  it'll be great when all done
