    Yeah I'm gutted! Just weighing up my options... So far I'm thinking I could swap the engine out (again), replace the head gasket myself (never done before unknowns with the block are putting me off) or take it to a garage to do it.

    Lots of white smoke, and a sweet anti freeze smell directly from the exhaust. Seems to get worse when warm.

    I've got a sniff tester on the way to be sure but looks pretty conclusive. Chalking it down to a lesson learnt as I made a few mistakes if I'm honest with you. Whilst wiring the engine in, I started it a few times for a few seconds to check with no coolant what so ever in it which may have heated each time? The engine crane also failed and dropped the engine (on the sump for around a foot which did no visual damage) this might have upset something internally and my final mistake was filling it with water initially just to get it going, I then left this overnight on a particularly cold night (1degC reported by the BBC weather site).

    I convinced myself I was worrying too much and it would be fine but it seems it was not. Perhaps when I said it wasn't too hard and I could do it, I was being a bit silly. Like I said lesson learnt and not too expensive to have another go... Picking up a new engine at the end of the month. Hopefully it will go a bit better this time.

    I do have one but seems like the sniff test would be a quicker easier way to test?

    each to their own, but you'd know for certain if you find a cylinder with low compression

    Yeah I guess a combination of tests would give a more definitive conclusion but I'm looking to be as efficient as possible with my time as I'm rapidly loosing motivation as it is. Thanks for the info though

    I don't think any of the things you are talking about would have caused the issue, more likely the donor was duff.

    I would pull the head off (once the HG is confirmed), its not the hardest job and if you do have a block issue you can fall back on the engine swap. as gasket and bolt set is cheap, so its just the time and learning.

    best of luck

    Thanks for the advice and luck, I think I will strip it down for a bit of practice and if it looks ok I'll order the bits.

    I'm just looking into the ECT senor diagrams for both E36 and E46 as I'm also getting some strange thermostat behaviour which may have had something to do with it... I'll need to get myself a scan tool (any recommendation? Carly?)

    E36 X20 plug pins 11 and 12 go to the ECT sensor
    E46 X60003 plug pins 24 and 25 go to the ECT sensor

    I've added a wire from the E46 X60003 plug pin 24 to E36 X20 plug pin 12 as per the loom instructions but how does this circuit complete if 11 and 25 are not joined? Does it ground through the block some how? I just had a poke around with a multimeter but I couldnt get anything to bell out oddly not even the ECT plug to X20 pin 12 so that may be a problem there. I need to have a bit more of a dig around when its lighter out... :think:

    Prehaps the best way forwards is to fit a 5 series M54B30 dual temp sensor and wire the dash gauge to that to save splicing into the single wiring...

    If anyone has a M54 diagram for the ECT or any engine wiring schematics in general that would be very very helpful as I'm struggling to find anything, appreciate it might not be the best forum for it but its been the most helpful thus far!

    Just did a eBay sniff tester, engine was warm coolant flowing. Stayed blue indicating no head gasket failure? The plot thickens...

    I don’t suppose you guys know if M52 flywheel and clutch kit fits an M54, both with ZF 5 speed? Both listed as 240mm with 10 tooth splines but they aren’t listed as cross compatible.

    I would take the car out and give it a good long drive mate, take a Jerry can full of water and your AA card and see how it goes

    Sounds like a plan I'll report back
