    Hey @Baggedcivic99 Have you checked the timing?? if everything on the ignition side has been sorted then the only thing it realistically can be is timing.

    Update..

    Done a compression test on the engine, cranked it three times and each where up around the 100 mark apart from cylinder number 3, there was no compression what so ever in the cylinder, my friend who is a mechanic said he’s seen low compression but never nothing what so ever.

    Unfortunate, I was hoping it wasn't compression and maybe just timing.
    Can you do a leakdown test? that will help diagnose what the problem is (I have suspicions that it will be piston rings, but if its top end related you could get away with just replacing valves/etc)
    We do however have parts you need for a bottom end rebuild.....

    Damaged piston or some valve issue possibly.
    Reminds me of my sisters Zafira which had misfiring issues I started looking into it one morning and ended up taking the head off to find piston number one had a lovely hole in it!

    Sorry to hear about the compression BUT at least you now know what the issue is and can start taking steps to fix it (even if its just for the experience of learning something new).

    Feel free to document your progress in here with lots of pictures etc. We would love to follow along with the progress

    What is a leak down test or do you know of any videos that would be able to show me how to do it? :Smile:

    A very useful test for determining the cause of compression loss.

    Cheers speedy, this is perfect for @Baggedcivic99

    will determine if the piston is dead or if its top end.
