Noticed over the past few weeks that coolant was disappearing from the SS every few days.
Would top it up maybe 250ml each time, but found it was getting progressively worse (more coolant each time)
Checked the water pump, that was all good. Checked the heater hoses, small drip from the heater tap, but fixed that by re-adjusting the clamp. No coolant in the engine oil, or in the trans. No coolant smell from the exhaust.
Finally found the leak after checking and cleaning all the parts i could get to. Could see the green drops hanging off a hose under the engine. Followed it back up the front of the engine. Could see it was wet on the front of the head, from there i could see it was coming from the second bolt back on the inlet manifold.
Stripped the fan and stuff off and cleaned up the area, put the fan back on and warmed the car and found it was seeping out through the actual inlet manifold, so figured there was either a hair line crack, or the bolt hole isnt fully sealed.
Pulled everything off and swapped over the inlet manifold with the spare one i had and put it all back together. Was a good chance to check the cam and was pleasing to see it only had a small bit of tarnish on the lobes, but the rest was smooth as.
With everything off, i could see it was the gasket that had gone, very nasty to look at with the inlet off, guess that is what happens after 220,000kms!
Everything back together and there is no leaks what-so-ever. no oil or coolant and the engine runs a little smoother now which is nice. Suspect it could just be a mind over matter situation, but maybe there was a bit of a vacuum leak as well.
