great, thanks. will have a look. assume its on the rad rather than on thermostat housing.

ok, some self education since i was stranded on the road the other night with "overheating" issue. the spare coolant sensor was 'green' type rather than the 'black' type which basically caused all sorts of inaccurate readings. i swapped it back for original 'black' one and ran engine up from...

seems to add up. bottom and top hoses are hot and water moves in reservoir when i squeeze the hoses. to close the loop on this one, can the temp sensors fail such that they don't read high (1/3 from cold when engine is hot). Original problem i set out to fix seems to be cured (no smoke/steam...

i am a little puzzled why it did not overheat before i did the gasket and head. what happens to rad? blockages?

hi James. original coolant sensor indicated about 1/3 way which concerned me post work above. i have filled slowly per procedure and by volume input of coolant it is correct. swapped sensor for one from spare engine which started rising before thermostat housing was warm, got to half way few kms...

sure there may be a minor secondary smoke, but the predominant smoke is vapour..clearly smells of vapour/coolant since it got worse. and the regular topping up of coolant. i will have it buttoned up by Sunday and will report back.

i will check with engineering shop tomorrow.

hi Jamesmartin. I brought head to a well established engine rebuild shop (with plenty of landrovers in the yard), they tested head and measured slight warping and thus skimmed head. I did not get measurements from them, but i can follow up. Any thoughts?

folks more updates. the head was for sure NOT a new head. if it was replaced recently then it was a USED head. the replacement was not good. gaskets were poorly fitted, studs in exhaust and inlet manifolds were poorly fitted. This is my first head replacement, but utilising the wealth of...

Just a quick update. took cylinder head off at weekend and pressure tested today. crack in an exhaust port. i will have more detail later when i collect from engineering shop. next step to pressure test head on spare engine. the head is not new despite what I was told when I purchased the...

yes new head. what i don't know is what supplier and if it was a fully assembled head. there is Mastic/grey silicone around the rocker cover bolts and cyclone. these are the only things i didn't like.

We believe around 150k miles. It had a new head installed maybe 10k miles ago. I purchased it 5weeks ago. It has a major rebuild, and is in super condition mechanically. Hence the engine donation from seller to help diagnose issue. He was not happy when i told him about the issue and wants to...

Firstly, thanks for taking the time to respond. secondly, well done on technical detail here. it all stacks up to make the most sense per symptoms. I am collecting a spare engine next week so will rule out low hanging fruit (injectors turbo etc) albeit i am not convinced these are root cause. i...

Hi Discomania. you have my attention. would you expect same on light throttle then just after overrun? and subsequently no smoke when back on medium/high throttle. the smoke at junctions is significant (when ticking over, and will plume with short bursts of throttle at junction).

hi Gymmaniac thanks for your help. i have not drained the tank to rule out fuel completely, which is probably the only true way to exclude. would it be the case that fuel issue would cause smoke continuously rather than just on/after overrun? i am.using the same fuel (from same garage) in the...
