  • Lol lori i work on yachts too so my life is 100% water based (bit like ky jelly hahaha)
    As for swapping shells :imout:

    Marco. i will track down some de springs as if i remember from stripping a k8 you need to remove the cams to get the heads off. just got a head gasket kitfor £75 which was a bargain. need to source some head bolts and they are off next thursday



  • A couple bits of advice.

    If you think its hydraulicing do not even try to start it as you might damage a valve and will put pressure on the crank and can damage that too.

    Don't get a cheap headgasket ie ebay or probestore, get a PAYEN gasket if you can you won't regret it. Much better quality.

    Heres a very rough non mx-3 specific look at the job:

    • flush out the rad and block before you start easier to do at the start
    • Cambelt off
    • Intake Mani off
    • Rocker covers off
    • Cams out, on most cars you remove cam pullys first
    • Exhaust Mani off
    • Make sure nothing is attatched to the heads
    • Head bolts out (you have to follow the pattern for removal found in the manual)
    • strip heads down
    • Send heads off to get checked to see if they need skimmed and for pressure testing
    • remove old head gasket
    • clean any old gasket off the block

    and your ready to rebuild

    Follow the manual, you need a torque wrench (avoid the cheap ones, halfords pro range are cheap and pretty good) and either an air gun (I know its a bad habit to use a gun for this but go into any garage and they will just set the torque where it needs to be and wizz them up) or I prefer a very long breaker bar to tighten the head bolts. Some cars head bolts are stretch bolts and may need replacing if they are not in tolarence.

    Some head gaskets want you to part tighten the head bolts then loosen, then tighten again.

    Also I know this is an old skool tim and a royal pain in the ass on a modern engine, but I like to go back after a month and nip them up. On some cars though (like mx-3) its really not worth the hassle.



  • Thanks Daryl, have most in hand, will do about the head bolts retighten anyway as its got to be done on all mazda 1.6/1.8 4 pot engines anyway
    Head gasket is on its way anyway and I have a new cambelt to whack on as well, I may even go water pump too just to be sure

    Where can i find DE valve springs in 3 days ???



  • The cambelt and waterpump have 100% done under 5000 miles before it came to you, as I changed before I fitted the engine and I never did 5000 miles on it.

    So if you do change em for peace of mind don't throw em away.



  • http://www.interpreptuning.com/

    They will point you at someone who can help, only heard good things about their valvesprings. They have resellers all over the place.

    Might be worth doing the valvestem seals as I never bothered going that far, so I know they are the original ones.



  • Also don't forget if you get DE springs you need DE retainers too not just the spring.

    Also i'm pretty sure the same goes for the interprep springs, I think you need the DE retainers for them too.



  • Any links to somewhere to buy them or just standard mazda ones are fine
    :mrgreen:



  • you need:

    12x valve springs
    12x retainers (the circle with the hole)
    12x collets (the semi circular locks that lock into the valve stem)

    I actually have 12x exhaust ZE springs which are the same as DE springs. However I don't have the retainers and collets as I used them on my interprep springs.

    postage will slow it down but:

  • above link is £43.00 inc shipping. I ordered a set a few days ago weirdly.



  • How much did you pay for your interprep springs marco?

    And where did you buy them from?

    Did you use the DE intake retainers and collets?

    But used the ZE exhaust retainers as they are the same as the DE ones?



  • 24 springs $190

    Though I also bought new retainers and keepers/collets for the intake side. KL31 exhaust side I reused. I think it worked out at $400 of bits, so £200 landed back in the golden years of $2:1£

    I bought new from Alistair Interprep tuning http://interpreptuning.com/

    They come up on occasion on forums, but it's not too often.

    TBH DE are fine unless you're high revving and have cams to make it worthwhile.



  • currently negotiating to buy a couple of sets and get them in the UK ready for anyone else that wants to do it :bigok:



  • ahh you're a good lad DJ!



  • Can you buy uprated head gaskets ? Or are good oem usually Ok ? Even IF you were talking boosted applications



  • Mazda oem are good for over 500whp :)



  • Good good, that's prob why I've never heard of a performance alternative



  • Mazda Direct or PAYEN gaskets.

    Just don't buy the crap from ebay or probestore they might claim OEM standards or higher but they are just cheap chinese crap.



  • IThe head gasket kit arrived today, its the same ones they sell at our local autofactors but half the price

    TBH at the moment I am struggling a little, house collapse, head gasket and over christmas while prices are rock bottom I filled my garage with used marine parts that have cost me thousands for my ebay shop so its now a waiting game - I had 7 outboard engines at 1 point now down to 5 although I did buy another from the bootsale sunday :shock:



  • The DE valve kit is purchased and on its way

    I purchased 2 so I will have one for sale when it gets here :bigok:



  • Sell me your ms bumper for a tidy profit :)
