Today I fitted the belt (although I'm not 100 percent certain it's tight enough so shall get checked out), I spun the crank with the belt on and it done 2 full rotations freely (a little stiff but I guess as not been oiled and the wheel drum a listed rusted).

Put new seal on cam covers, and refitted vacuum pump (not 100 percent sure which hose connects to the top, as I foolishly didn't take a clear photo, there are 2 options, anyone know where it connects to of I trace the hose back).

Going to take the vacuum housing which the EGR valve home to de carbon, then can go ahead a put that on. Once I know the belt it set to right Torsion, I can put timing belt cover back on, engine mounts, wheel and lower car.

Sorted the belt out. Felt a lot better when I'd left. I was turning the tensioner the wrong way, hope I've not buggered the spring but it feels a lot better now.

That's one bit I've been worrying about... Turning the crank and it all spins okay, can't feel it hitting the pistons, guessing you would know pretty sharpish as it would spin any more?

Sorry disregard last few posts as I was rambling lol, I have had a couple days of due to night shifts but now off again to hopefully complete this.

I am pretty certain I have set pistons and valves up correctly, but still find myself worrying about it, I don't want it to be game over this far into the project.

The crank shaft spins 2 full revolutions, before the cam shaft is back in starting position. So although I have set the notches up on the crank shaft, and the marks up on the cam shaft before refitting, do I have to ensure that the crank shaft is on the correct revolution. I hope this makes sense.

Yes, it should be on its 'up' stroke, so when you rotate it in the direction of rotation the piston should move from the timing mark up the bore, so its on its firing stroke. If its moving down then you will need to release the belt and adjust accordingly.

Is the Piston at the top on both revolutions. Im pretty sure it's right.

Manged to get everything back on now, including engine back on mounts. Next step is the injectors, do I need any specialised tools for measuring gaps or do I just screw them back in. I had the injectors replaced about 10 miles before it broke down lol, so the copper washers should be okay, and shouldn't need to clean the seats, except for a little bit of oil at the bottom...


Also I had these parts left over from my gasket set ? what's was I meant to replace what I didn't, as do I need to back pedal or is it too late ?

The packet on the right has valve guide oil seals, i assume the person that done the head has put new ones on when reassembling?? the other seal looks like camshaft oil seal located behind the cam sprocket,

Oh god why didn't I look I side the pack.

The head was skimmed and valve clearances set up but was a used head, not refurbished so I don't believe these were changed. I hope this doesn't come back to bite me in the arse.

Might be worth asking the head builder.

The head builder? Lol this was off a used car so wasn't refurbished, I put it back on myself. I can't take it back apart again now. Shall hope for best.

Putting the injectors back on... Do I need to measure gaps or anything, or just put them back on.

This was going so well lol, how did I overlook this step.

Ordered some new copper seals for injectors... Before realising I had 4 brass ones in my head gasket set. Which ones are best. They are different shape and material but apparently both for engine

Thanks

It seats them in the washer and seats the washer in the head.

Arghh okay. Perfect thank you. Injectors are now in.

No fitting cover back on top, it asks to 'apply vauxhall sealant to cam shaft mating surfaces', I assume the sealant I used for the thermostat Loctite SI5660 would be okay.

Also can't find a gasket for the throttle body, in fact can't remember removing one but the manual says to replace it.

Can't find any for sale online either ?

Thank you, made gasket, very very nearly finished...

Just putting the leak off hoses back on, but as the garage had written this off they didnt put it back together, so somewhere between the garage and towing it back to my barn I have lost 1 tee connector, and the end connector for the leak of pipes... There are plenty of Astra H connectors on ebay but no J ones. Are these a standard connector or any ideas where I can get them from.

Thanks
