As above, are there any indicators for early diagnosis of an impending headgasket failure?
Can someone comment on these symptoms:
1)over the last few days, ive started to notice a lag in acceleration from rest (at first), now manifests at other engine speeds (very occasionally, but noticable). I came across in passing yesterday someone saying that such a 'problem' is early signs of head gasket going. true of false? i decided to have a look around the engine and discovered number 2:
2)After inspecting the engine, i notice a circular patch of 'oily wetness' (not dripping) on the side of the engine centered around the headgasket. Its between 2 cylinders and extends above and below the HG. This can only really be one thing: oil slowly leaking out of the gasket.
3) Ive only just bought the car (2 weeks ago) but noticed straightaway that the temp gauge was not working properly or the car is not getting to running temp as it barely lifts from its stop. It may get to 92 deg. This was going to be a minor problem to sort out but now i wonder. Does the failure of a headgasket affect the running temp of the engine?
The car is a 3.0 12v senator. Im glad its not the 24v as hopefully with the 12v i may dare to take the job on.
How long do you reckon i have before it goes: phut-phut-phut...TWANG? lmao
So what signs are there to look out for to spot HG failure?
