Coolant issues nightmare

[Zero4]

Compression test came back fine. He had it running for a few hours straight afterwards and no overheating at all. It It blew its coolant and overheated for me when I was on it so wondering what it can now be.

Its had new sensor, new coolant tank, new cap is on order now to see if its as simple as that.

Anything else I'm missing?

A compression test won't necessarily identify a blown head gasket.. It needs a chemical combustion gas test performing on the coolant whilst the engine is running.

Stuck a new cap on it and bled it out. Is it possible that all this was caused by a loose cap and some air lock?

Everything seems fine my Indy says it’s running wel, not overheating at all and no coolant loss.

It’s had us baffled but worried about longer journeys now.

Sounds like you need to have progressively longer drive outs to gain trust in it. When the head gasket went on my old Triumph Stag, it took quite a few runs to with lots of stopping and checking for drips, until I was happy.

Yeah agree. Got the car back this morning, ran some chores I had to do, did some shopping, some work stuff and generally pottered about in it. Going to take it easy with it for the week, check levels, then some longer drives with a little more spirit to ensure it’s fine.

Book time to do the head and valves is a whopping 17hrs.

Just the head gasket alone books at 11.5hrs, so can't see any indy doing that job for £300..

that quite a chunk of time but if it is any consolation to change the head gaskets on my X5 is 48 hours and requires the removal of the engine
