Hiya there Im new to scooby world and this is my first subaru rebuild im doing ive put the heads back on and all torqued up,

some buckets came out so i put some oil on them and oil feed/slipped them back in. they have all gone down as much as i can push them but there still sitting out abit..

i then fitted the camshafts they wont spin all the way round as the buckets are in they way..

I have been told im doing it right and the buckets will go back down when cranked over as they will be to tight to push by hand..

so im being told im doing it right but know im doing something wrong can someone give me some advice
i also dont understand if they valve are open or closed and valve clearence and what should be the valve clearence how do i check how do i adjust

Any one please

OK this simplifies things. If it has the original heads they will have hydraulic litters so no need to worry about valve clearance. They should be backed off though before fitting by CAREFULLY using a vice or press,but you may get away with it if they are all fitted to the valve they came off, but best to do it anyway.
When the cam lobe is pushed all the way down onto the lifter the valve is open. The cam should move easily with fingers if bearing surfaces are lubed properly,however when the lobe contacts the lifter you are pushing against the valve spring & will need a spanner or ratchet on the cam sprocket bolt or cam hex. It will be tight to turn make sure you don't let valves touch each other or the pistons.
Good Luck, Rich.

ok cheers rich mad a bit of sence but i really do not want to take heads of again lol is there any way i can push buckets righ down with spanner ect to clear the cams?
cams are moving only 180/ half way round as they catch/touch.. buckets are stopping it.
i didnt understand the last bit did you mean when torqing the cam pulley to use a spanner on the cam sprocket bolt/cam hex ?

You need to turn the cam with sufficient effort to push the valve open. It will be tight as the valve springs need to be pushed down. Make sure the pistons are far enough down not to bend valves on them. Buckets can be removed easily when cams are out with a magnet, no need to remove heads.

Ok before I put heads on I crank engine over so the marking is lined up with timing markings on block. Then put heads on. I dont want to force the cams round till I know its ok to do so incase I fk it.

Sorry mate, if you were near Notts I'd pop over & take a look. If in doubt take heads off,but you will need to use some effort to turn the lobes past the litters. You need to turn them with a spanner it will be too hard to turn without.

I'm cringing at this end..
Honestly mate, in the same way as you wouldn't attempt dentistry on your girlfriend (assuming you actually like her) you are verging on the point of serious engine damage.
Do what I do when it comes to the telly, and get a bloke in quick.

If you are still struggling why don't you take it to Alan before it goes **** up. You can only get a rough idea of what to do on a forum,& if you are still not sure best to let a professional do it before you bend valves or worse.

I'd suggest you get the engine to someone that knows what they are doing, or do a bit more research before proceeding further, the information is out there and there are videos on youtube.

I don't know about the early heads but judging by the reaction of Alan your about to make an expensive mistake.

Good luck hope it works out for you, it's not as difficult to do these engines as some would have you believe, but you do need to do it properly otherwise it gets very expensive, and like i said the information IS out there.

right i have got all buckets push in as far as i can push them, all cams are fitted all pulleys are in timing position... belt is on should i crank it over.. all the way round 360.. to see if it all lines back up ? only thing im worring about is the cams are only spinning round half a turn as the buckets stop the cams ??

ok im taking heads back of and taking it to my local garage as i know the manager/mechanic very well i will get him to look at head and get him to sort the head

morandpeter

iTrader: (5)

good for you lad, i know its extra hassle but it'll be piece of mind in the end.

are the heads straight or are they needing skimmed? might be worth getting him to check while he's at it

dean_1991

iTrader: (1)

yer the heads are fine dont need skimming ect but ill take them both back of and give them both to him and ask him to check again if needing skimming and also why are my bucket not going right back. ive pushed them back as much as i can but they all are sitting out abit witch isnt giving any clearence for cams
