Been some time since I've posted about this, as I'd hoped to get it all up and running, and then post.

...However, a big question to ask, and it's either a headache or heartbreak.

Everything bar the bumper cover and lights fitted. All the fluids done (water, oil, transmission and steering) and decided to throw in a can of radiator flush. Ran engine up to temperature at idle, switched off, left to cool and then drained the water.

Possible problem. Water was cloudy and felt slightly oily. Assumed this was from the radiator flush, and proceeded to fill again with water (as instructed) to flush out any remaining radiator flush.

This time I took it for a short drive up and down the lane, about 1/4 mile to clean the brakes, let it cool and proceeded to drain.

Big problem! This can be summed up as either 'oh s**t' or 'oh f**k!' A lot of oil in the coolant. Pulled off every pipe and every bung to get coolant out, and then proceeded to just put a hose in the coolant tank and run it until clean.

So it's either the oil cooler pipe (or oil cooler itself) or worse, a head gasket.

I've Googled the living daylights out of this and the majority of results are 'coolant in the oil'. Here's what I know for sure.

1. Engine was running fine, both on petrol and LPG
2. No smoke from exhaust
3. Lots of oil in the coolant
4. NO coolant in the oil (I drained the oil)
5. Substantial amount of oil has gone AWOL
6. No signs of oil/coolant coming from oil cooler area

If it's the oil cooler, I can work on that and still get to the annual meet. If it's head gasket(s), it's doubtful if I could get that done in time (I haven't read up on what's involved with that), and I still need to MOT it before the meet as well.

Is there an easy way to check for head gasket damage?
