Cheers for the info, much apprecited.

Good morning gents

Are the UK and USA m20b25 six branch manifolds the same? The only reason I am asking is because I have been looking on ebay and all the USE ones seem to be different on section where they connect to the middle box of the exhaust.

Chris

I have recently rebuilt the top end of m20b25, but after reassembly I have noticed an air leak that sounds like it's coming from under the inlet manifold on the side closest to the cab. The car also seems to be idling very rough and I am guessing that it is because of this. I have taken the inlet ma...

Cheers lads, Good advice.

Hi I am after a price please for some new exhaust manifold bolts for my m20b25 engine. I only realy need 4, but not sure if they can be bought individually or only in a set.

Chris

Where can I get new exhaust manifold bolts for my M20B25?

Cheers

I turned one of the bolts to 180 degrees on the first set of angle tightening in error, shall I slack it off and restart on that that one, ie: 30nm then 90 degrees and 90 degrees again?

Good advice lads, Cheers.

When I line the marks up on the cam does it matter which valves are open and which are close, or are the valves automatically in the right sequence when the marks are lines up?

Much appreciated lads

I have now put my cylinder head back on my m20b25 and just want to know what the correct procedure is for tightening it up, ie: torque settings and do I need to do the 90% angle tightening aswell and also any other tips if anybody has any.

Chris

I am going to put my cylinder head back on to the engine today, m20b25, but I just want to make sure that the valve positions are right before I do so. No 1 and 6 pistons are up, so should the valves for no 1 and 6 be closed when I put the cylinder head back on?

I am ready to reassemble the cylinder head on my m20b25 engine, but I can not find any engine assembly paste in any of the local parts and accessories stores, would I be able to use copper ease for reassembly, or would it do more damage than good?

Any help would be much appreciated

Chris

Cheers for the info lads.

So as long as I get 1 and 6 back to the top before putting the cylinder head back on, I should be back at TDC?

Reassembling the top end on my m20b25 what is the best way of cleaning the tops of the pistons while they're still in the block, 1 & 6 are up and the other 4 are down.

I have now got the clinder head off and trying to strip it, I have loosened all the eccentrics and most of the rocker arms are loose, except for two, which are still sitting very tightly against the camlobes and the valves, how can I supress these two valve springs to release the tension on the cam ...

Some help please ladsm I am doinf=g a cylinder head job on my 1991 325 i and I now need to strip the cylinder head, what valve spring compressor do I need to strip the cylinder head?

Cheers

I want to adjust the tappets on m20/b25 engine, do I adjust them when the valves are open or closed?

Chris

Thanks for the mtech pedals Mick they look great in the car, If all E30 zoners delivered things as quickly and hassle free as you, I'd stop using e-bay, thanks again mate.
