    Icon5 head bolt tension

    What is the head bolt tension on mi16 1.9. the book says to use an angle guage which i dont have. Just thought a lbs tension would be easier.any advise would be appreciated.

    Teng Tools torque rench have an angle guage on the ratchet head. not shure if this help but they are great value at around $100 and are indervidualy calibrated.

    If you get a simple plastic thingy from your local newsagent you can cut a hole or a relief in it so that you can put it on your extension bar and work to the right angle from there.

    'Thingy'? Yeah, I'm trying to think of the right word... it just won't come to mind... but you know what I mean, the half round things with the degrees marked on them up to 180?

    all you need is a piece of wire clamped onto the externsion bar and a piece of cardboard with the angles marked on it

    You use that to set up your expensive bit of bent wire...

    I think from memory it's 300 degrees, after the first two pretension sequences.

    I don't use a protractor though, as a Torx bit has 6 edges anyway. I use a long breaker bar and it's very easy to work out where 300 deg. is before you start the final tighten of each bolt.

    Someone sent me an email with an alternate sequence. I'll see if I can find it

    Petera,

    Don't forget to measure the length of the removed head bolts-if any have stretched longer than the specified length ( I think it's 176.5mm from memory), you'll need to replace AlLL of them.

    Default head bolt tension

    Peter,
    I would like to be around when you do the final 300 deg. pull!
    If the engine is in the car it should be manageable. If mounted on a stand you will need half a dozen strong lads to hold it down

    very true

    bad enough doing 120deg pull on a PRV

    much easier in the car

    in fact when i built the 604 engine a while back 2 of us lifted the block in by hand and i then set to and built the engine up from there once it was in there for the rest of the day

    Hold the socket bar and turn the engine stand ?

    As long as the stand is pointing the right way and you put moly on the bolts, it's fine. I've given up on 2nd hand bolts. New bolts will pull up easily, but old bolts creak and grone, regardless of their length. I've had one break and it's not a pleasant experience.

    "The tightening sequence recommended by Peugeot Sport for the
    Gr.A MI-16 cars factory-spec. (309 GTI 16S Gr.A) - it can be used on any alloy block XU engine running a very high CR and a special steel gasket:
    1) new bolts unconditionally !!!
    2) lubricate bolts (grease on threads, motor oil under head/spacer)
    3) tighten all 10 bolts (in the "spiral" sequence) to 2 mdaN
    4) tighten all 10 bolts (in the "spiral" sequence) to 4 mdaN
    5) tighten all 10 bolts (in the "spiral" sequence) to 6 mdaN
    6) loosen bolt nr.1 and tighten it to 8 mdaN
    7) repeat point nr. 6) for bolts 2-6, and stop.
    8) loosen bolt nr.7 and tighten it to 6 mdaN
    9) repeat point nr. 8) for bolts 8-10, and stop.
    10) that's all. No further re-tightening is needed.
    The spiral sequence is:
    ------------------------------------------
    exhaust
    9 5 1 4 8
    O O O O
    10 6 2 3 7
    cambelt side flywheel side
    ------------------------------------------"

    So this isn't 'torque to yield' Peter?

    What's the meaning of this strange business with the lesser tension to the four outer bolts?

    I didn't say I did it that way. Notice it's in quotation marks.

    Oh, I noticed that all right...

    So assuming you are quoting from some official manual or whatever, why do you think they might lessen the torque on the outer bolts?

    And why isn't it done by the normal 'torque to yield' method?

    petera,
    Had you already removed the cylinder head before you found that an angle gauge is a necessity for replacing the head?

    Im staggered to read in these posts how owners get stuck into different jobs without reading up on what is required and when good advice is offered will question it!

    In order to use a torque wrench instead of the degree plate to replicate a 300 degree pull would require a wrench calibrated for use on large earthmoving or industrial gear.

    Peter T,
    The convoluted head tightening procedure provided for Group A racing Peugeots could be explained by their design.
    I understand that the racing engines have the head layouts reversed ie exhaust at the front inlet at the rear. I believe also that the engines were built by an outside specialist, Cosworth? comes to mind.
    These specialists would have their own head tightening procedures.

    calm down. I have not questioned anybodies good advice. And yes I did read the haynes manual. But I have found from past experience it does not hurt to seek others opinions.Which have helped me in the past

    petera,
    Apologies for my seemingly pointed comment, proof reading and re-wording should have been in order.
    Suitably chastised,

    Just a small point, peter a... don't look for opinions, look for experience...

    There's quite a difference. Someone who's never done the job can have an opinion, but they certainly don't have the experience.
