    Still dealing with minor teething problems, since getting the car back OTR. A couple of fluid leaks, gearbox front seal (annoying) and a diff flange. But one major problem, is that I managed to blow the head gasket recently (long story), but my own fault.

    So, the car is going into a specialists, to have all the minor bugs sorted, including respraying the bonnet (which is not good), some other things that are bugging me and obviously the head gasket sorting and a tune up.

    Whilst, it's there, I'll crack on with the other project and get the engine fitted.

    Other than that, the car is a joy to drive, get's so much attention and drives great. Surprisingly fast. I love it.

    It's not exactly exciting. But, the mechanical cooling fan is really close to the radiator. One engine mount has a 'stopper', incase of forward movement, which has to be setup with a specific gap (3mm). I had neglected to do this properly when I dropped in the engine.

    So, I was out one day, driving the car like a loon and luckily, I was on my way home, not far from my house when I noticed the temperature was in the red. I managed to find somewhere to stop and the fan had cut through the bottom of the rad, causing a total fluid loss. So, I'm guessing the engine must have moved forward under braking ? I replaced the rad, with a spare I had, but I suspect the damage was done, the thermostat must have also been damaged, because the car then kept overheating.

    So, I bought a new thermostat, but the car was still getting hot when it was being pushed, until eventually, it gave up about 1 mile from home. I then managed to limp it home and did a compression test, with no compression on 3 and 4. I am only guessing it's the HG, I have been advised that, given the circumstances, it's the most likely scenario.

    At least you are honest and told us your mistake. I will bet everybody has done a similar self inflicted mistake. best of luck with the head gasket scenario in that there is no other fault, i.e warped head needing skim!

    Bit of an update on this. It WAS the HG and it was fixed. The head needed a skim, but it is back on the road. However, I have a low oil pressure problem, that I am now chasing. I just hope that's nothing too dramatic. The car runs fine, but the oil light keeps coming on at idle, once it warms up. Could be as simple as changing the oil for thicker stuff, or worst case, wrong size bearings. We'll see.

    Anyway. Here's a pic of the blown gasket !!!

    Update on this oil pressure problem. I sorted it in the end. I had to strip down the front engine cover, timing chain, etc, etc. It was a goddam, £1 'O' ring that was missing, where the oil pick up pipe enters the block. Car runs lovely now......almost. I might have to invest in a thicker HG, since I think I have a bit of chain rattle going on at higher revs. The head has been skimmed to it's min thickness, but only using a std gasket. Just more fun and games, I guess.

    On a more positive note, I have decided to fit some BBS RS 3 piece wheels, which I am rebuilding at considerable cost !!! Can't wait to get them on the car.

    I repainted the chip tray on my Bantam lathe, then lowered the bed onto the cabinet with my dad’s help stop it scratching the new paint, perfect job... went to get the bed bolts, then I saw them there - the O rings! I’d forgotten them, they stop coolant leaking through the frame. I know the frustration!

    @B1N9S I've been wondering about you and your 2002, glad you got the engine sorted. Were you able/did you bother to work out the increase in CR after the head skim?

    Those BBS are going to look excellent on the car, and worth every penny. :thumbup: Easy to see I'm not footing the bill, though. :D

    It was an OEM from BMW, so I guess it's fine.
