    1991 Tornado Red Corrado G60 Daily / Project

    Hi guys,

    Thought it was time I put up a thread on my recent ebay purchase.



    Lovely looking car on the surface, no welding so far but will need some work done to the front passenger sill where its been crushed. Its rotten behind the seal at the top of the drivers side windscrean. Its needing replaced anyway, I just hope the auto-glass man can leave it with me a couple of days inbetween removal and refitting so I can repair it. Its also leaking water somewhere but yet to verify its the screen causing this.

    Other issues is the interior as its not great and not put together well. Bits missing here and there. Front seatbelts are not mounted to pillar correctly and rear belts not even there. Have Mk2 Golf ones there but not sure they're the same. No parcel shelf or spare wheel and boot carpet. Central locking not working most of the time. Front strut top are hanging off it, ruining the osf tyre on inside edge. Small dent in osr wheel arch. Has a momo steering wheel I want to swap for a standard one and aftermarket rear lights i'm not too keen on. Bit of laquer peel on ns door and a few wee other stonechips etc but nothing major there. Loads of history adding up to 10k+ and recently had a new distributor and fuse box done at Trix.

    The job that takes priority though is changing the engine as sadly after only the second day of ownership one of the pistons melted. I have one lined up, a 1H Rallye engine which is low miles apparently but has sat for a while.





    Obviously i'll need to figure what caused this as usually related to a fueling issue. Poor injector maybe. I'll probably clean up the bay and paint the new engine while its out but all dependant on cost and motivation but morale is low with this just now. At the stage where I wish I never bought it and just kept my tidy mk3 vr6 but I know it'll pass once some progress is made and it'll be worth a good few qud once its done. Just want it running and on the road as it's still mot'd till august. Still waiting on docs from previous owner due to private plate going on retention so cant even tax it until then but its been about 3 weeks so hopefully not long to go. Also need to recieve docs confirming last charger rebuild as left them behind when I collected it. Apparently on a stage 3.

    So anyway will begin work next week when i've finished other jobs. Currently respraying a rusty old T4 for someone but should have that in paint on tuesday.

    Love a Red Corrado, stick with it mate, it will be worth it once you're up and running.

    Picked up a rallye engine at the weekend. Just a head and block with low miles but has sat for a good whille.

    Anyway got it on the engine stand and began ripping it apart. The head's fine, real good condition. Will just require stripped, cleaned and rebuilt. However, although the bores are really good in regards to wear as it's practically nothing, some moisture has got into one of them and suffered some corrosion or a build up of rust. This is what i'm left with after cleaning away all the brown mankyness and hitting it with wone wd40 and some 2000 grade wet and dry.



    I'm not sure on the what the next best course of action with this or if it's needing the machine shop. I have a bore honing tool for the dril and various air tools that I could try. It is quite prominent when you run your finger over it.

    I also had some movment of the same piston so removed it and found the ring to be sticking which after cleaning up seems to be fine. Some moisture got down there too.

    Other than this everything else appears to be spot on but yet to do any measuring but it is obviously low miles so in general i'm happy aslong as I can resolve this bore issue quickly.

    Some other pics.

    Right then, i've had the block inspected at a machine and had the bore honed and its much better but still there although much less obvious to the touch. Obviously a rebore would 100% cure the problem but it's not an option just now so i've decided just to build it up and see how it goes. I'm hopefull the rings will sort it out. Basically run it in and keep an eye on the compression and oil consumption.



    It's not ideal but no other option really. I'm confident though.

    So going to start building it back up tomorrow then commence with the swap.

    I've had a very similar problem with regards to the bore. I had my fingers crossed that the wear wasn't too high in the cylinder as to lose compression. Mine seems to be fine at the moment, but it's a 9A running carbs. Maybe more of a problem for blow by, I put an oil catch can on in case of high crank case pressures, might be an option for you too.
    Aqua Blue VR6, 16" Speedlines, Stainless Exhaust, K&N 57i. Love it.
    Tornado Red Scirocco, 9A on Weber 40s, 16" Speedlines.....
    And many, many work in progress!

    Yeah i'll see how it performs once running and take it from there. Despite the charger, it'll be getting driven very carefully for a while. As you can see the marks on my bore are quite high which is a concern. If it was any higher I wouldn't attempt it.

    Couple of the infamous piston nunberm1 now removed from it chamber of carnage.




    The 1H block now has its pistons back in along with some new big end bearing shells. Also stripped and cleaned the head. Its had some previous porting done on the inlets. Just now need to get the various seals and gaskets to build it all back up.

    ouch, real shame about that piston, certainly not the best start to G60 ownership!

    Key question, why do you think you melted a piston? aftermarket chip, too much boost, poor ignition/fueling any ideas?

    Looking forward to seeing another early corrado being saved to!!!!

    Yeah it's been a laborious jorney so far but we're getting there. As for the key question i'm not sure. Definately running lean and detonated that piston. Will need to run some tests once it running. Bad injector hopefully considering the problem was confined to only one cylinder. I have a spare.
