    Hi Young man
    How are you doing, you still putting in the mileage to trackdays, you still got the Clio then

    Will have to see what power it makes, but i was going to just make sure it wasn't going to throw a rod, or drop a valve like the last engine did.

    I'll put up the trackdays i'm doing and we will have to meet up at some point this year.

    Going to try and get to either Anglesey or Oulton or Donington in March to be near to where i'm going to get my mapping done.
     
  2. good work, for my own personal knowledge whats the rings gaps top and middle you use?. and piston to wall clearance..bernie. may end building my own in the future.

    I took the block to an engine builder to get it checked and he gave me the all clear to just fit standard forged pistons, even though my engine has done 115k miles.

    It will depend on the make of pistons and rings you use, but mine were 18 thousands of an inch gap on the top ring and 16 thou on the 2nd compression ring.

  4. no rebore needed?

    No
    Was very surprised, he said it was perfect

    Yes i was shocked, 115k miles and 20 plus trackdays in the last 18 months

  6. I'm hoping to do anglesey on 4 March!

    I need to speak to efi about my mapping but it currently has no seats and I'm changing the os swivel bearing so reluctant to set a date until it's all up and running!

    Good work on the build progress!

    same for me, i can't book anything yet till at least the engine is built and ready to fit.

    Iv'e not done Anglesey in this car :openmouth:
     
  8. good work ian..i expect nothing less from a engineer!

    ha ha ha thanks Andrew
     
  10. keep up this build thread though Ian...its good information for people to see the more technical engineering side of the forging.
     
  11. Good job mate.
    And in the stock what work will you do?

    Sorry not with you
     
  13. Hi Ian
    Thanks for sharing this with us.
    Would you recommend forging an unmodified R26 230bhp engine being used mainly for TDs?
     
  14. essentially the same engine as a mk3,but has weaker pistons and rods.
    If its standard,and all is well,then unless you are serious about a lot of track work
    ,its a fair chunk of money on a ageing car.
     
  15. What’s the general view of reliability on a Standard 2014 265 cup engine( well apart from K&N air filter, vibratechnics lower gear box mount and powerflex yellow engine mount) coming up on 50,000 miles and due timing belt change soon. Doing trackdays? Safe. Car is used pretty much everyday, I do about 3-5 trackdays a year only other mods to car are braided brake lines and different pads.
     
  16. Will be getting timing belt and all other necessary work done before next trackday, obviously.

    Yes i would if yu can afford it, if a conrod decides to take an exit, then its finding another engine to forge :cry:

    Its very hard to say exactly, mine has or had done 115k miles, owned by and 84 year old before i bought it 18 months ago, i only use mine to drive to tracks and for track days and mine was in very good condition inside when i stripped it, i do know someone that there a rod came out around 60k, Jamie had his go with less miles than mine, at least i know now mine is safe.

    Mine was only running a cone filter, still had the cat fitted, suspension and brake line and pad upgrade.

    this lot turned up yesterday, my job on Sunday, maybe tomorrow will have to see how it goes in the morning :pensive:

    I want!

    Do you have the details now ????

    Valve numbers
     
  22. Now you've got me thinking you're aiming for big power....

    No, reliability
    Look at my 225 re engine thread :rage:

    On Thursday i had a bit of time in the workshop, the weather was awful down here.

    I got the valves
    49479659773_054df404bb_k.jpg IMG_20200131_120145 by Ian Austin, on Flickr

    Then spent hours lapping them in :cry: but it has to be done.

    random old valve spring measurement

    49479662198_ca1b08422f_k.jpg IMG_20200131_120512 by Ian Austin, on Flickr

    and the new spring measurement

    49480362517_d7f3614a59_k.jpg IMG_20200131_120550 by Ian Austin, on Flickr

    Was a bit surprised the new ones were a smidge shorter but they are a lot stronger.

    these are required for the new exhaust valve

    49479663718_e3582fb0df_k.jpg IMG_20200131_120629 by Ian Austin, on Flickr

    the inlet valves are single groove so you can use the ones you take out

    49479656238_1ca4c8293d_k.jpg IMG_20200131_115906 by Ian Austin, on Flickr

    the old / standard exhaust valves valves are 3 grove so you need the keepers above for the new valves

    on final fitting of the valves it is now that the valve stem seals get fitted, its also worth putting some oil down the valve guides, this will help for the first running of the engine and it will help not to damage the seals.

    When fitting the springs, caps and the collets / keepers, i found the best way was to grind a flat on an old small screwdriver and a dab of grease to hold the collet in place, the aperture that these have to be fitted in is not very big, no fat fingers or even small ones can really get in there.

    Also a bit of grease on the inside of the collet will stop it falling out once in position.

    49479664493_e0bb237c2f_k.jpg IMG_20200131_150622 by Ian Austin, on Flickr

    Release the valve spring compressor slowly, if the collets are not in fully they can go flying.
    Check each and everyone of the collets and make sure they are in there correct position, not like this

    49479665898_b19904bb09_k.jpg IMG_20200131_150904 by Ian Austin, on Flickr

    Make sure they are set in fully

    49479666578_d4042a83c2_k.jpg IMG_20200131_151055 by Ian Austin, on Flickr

    you can see that there isn't much room in the head for these valves and fingers

    The business side of the head with all the new valves fitted

    Fit the head gasket, lower on the head onto the block, fit new head bolts as these are one use bolts.
    Torqued down the head.

    Fit the hydraulic tappets, cam followers and then the cams

    49480149056_c094f16271_k.jpg IMG_20200131_164247 by Ian Austin, on Flickr

    lube it up well
    There isn't a gasket for the cam cover, so its smeared with Victor-Reinz Reinzosil Instant Gasket

    49480537962_9aa5750286_k.jpg IMG_20200131_162035 by Ian Austin, on Flickr

    Then fit the cam cover, this needs to pulled down evenly, there are lots of bolts so it takes a while, then when there down then torque them.

  29. Nice work.

    Something that's always baffled me is timing everything up!

    ianplymouth RSM Club Member

    Now this is where someone has a pop at me :laughing::laughing::laughing:

    I don't use the timing kit, its quite easy, done 4 or 5 now, i borrowed a kit to do one and found it so awkward to use.

    Did mine yesterday my way, i just turn the engine over a couple of times to make sure its all lined up.
     
  31. Lapping valves can do one. hateful job
     
  32. AH the good old days. If I had a £1 for every collet that had flown past my head, vanished, never to be seen again?!. Spent many happy hours, lapping in valves, while listening to workers playtime, with Charlie Chester!!. ( Ask your Grandad!.) Great thread Ian.

    Wish i could mate, wish i could

    Yes the radio on really helps, but Elaine Page really grates with me, so glad i did the valves on Thursday :laughing::laughing:

    So yesterday i fitted the flywheel, clutch and gearbox.

    also fitted the new dephaser pulley and cambelt kit.
    fit the front covers and the crank pulley.

    also fitted the manifolds, spark plugs and coils

    49479670678_3a1a31e6f4_k.jpg IMG_20200202_125649 by Ian Austin, on Flickr

    Then it was onto fitting the starter motor, alternator, AC pump and then the wiring loom

    49479671783_849900e9fe_k.jpg IMG_20200202_142835 by Ian Austin, on Flickr

    now nearly ready to go back in to the engine bay, i have a couple of other bits i need to do before then.

    Also i'm replacing the seals in my front calipers, does anyone want a pic show of that job ?????
