If it does the same job, I would't see why it would make a difference.
Put the repaired & reconditioned head back on last night using new Torx-head bolts instead of the original hex bolts.
Tightened everything according to Bentley.
This morning I was reading Bentley again and noticed the word "washers" .
Should I have taken the washers from the old bolts and used them with the Torx-head bolts. The new head bolts look like a bolt head & washer together and didn't come with washers.
Thought I had better check now before I reassemble everything else.
Does it matter ?
Do I need to start again ?

According to the etk an m20 525i should have a torx head bolt and a separate washer

I am a little annoyed, however, that they were not supplied with the new bolts - that would have made everything crystal clear.
I presume that I now need a new head gasket and new bolts plus new rocker cover gasket - oh well I live & learn !
By the way Bill R, thanks for the new tightening protocol, however that is the one I used as that is also what Bentley recommended.
At least I can say that when I instal the new bolts it will be the second time I have put a BMW head back on !

Zeuk, I just did the same job on an M50 head and most of the washers stayed 'put' on the head through the process.
To get this straight, were the original head bolts installed without washers? The new set of head bolts I used arrived without washers, but I used the existing washers for the insall.
Anyhow, hope you figure it out,

Mine is an early M20 motor from which the head had never been removed. These early motors came with hex head bolts and washers.Originally Posted by Dave M
I ordered a set of new head bolts - torx and they were supplied without washers. What confused me was that they look a little like a bolt head with a washer and so I used these without the washers from the hex bolts.
Obviously this was wrong and I now need to remove and re-instal the head.
My stupidity and lack of experience !
I wonder if the village idiot has died or retired and I am about to be inducted soon ?

Is it not possible to remove each bolt, put the washer on and replce the bolt one at a time, like the procedure for broken bolts mentioned in BillR's bulletin?
All the best

That's I would have thought. One bolt at a time.Originally Posted by BobHarris

Possibly, but given that I have to buy new bolts anyway, for the cost of a new head gasket I might as well do it properly.Originally Posted by pundit
I haven't done any more to the car since I bolted on the head, so have not much to lose as far as time or effort is concerned.
