Title: 400-4 valve spring installation - is there a right way up?
Post by: DayvW on May 11, 2014, 08:17:15 AM

At last I'm putting my 400-4 engine back together .. so far so good ... bottom end complete and on to the top ...
I saw mentioned somewhere that valve springs should be installed the right way up.  Is this so - and if so - how can you tell which is top and bottom as they look symmetrical to my untrained eye?

The tighter coiled end of spring goes to the bottom same with inner spring if I remember right.If I am wrong I am sure the 400/4 guys will put me right

Thanks Bitsa .. just looked more carefully and indeed there is a tighter coil end that I did miss  :-[.  That also makes sense as on one of the springs it still has collet holding washer thing on the looser end.  Mind you - I have found much wrong from a previous top-end build which further reinforces the message that you cant rely on previous work actually being done right! Many thanks again.
