I was driving down the M2 and as I approached Windsor Rd the engine started making what I thought was a fan belt slipping squeaking sound. It stopped after about 30 sec. I turned off into Windsor Rd and the squeaking sound returned then the engine died. The engine would restart but only stay on for 5sec before dying again. Eventually the NRMA towed me to a servo. After about an hour of cooling down the engine would stay on but now made the sound recorded in the video below. (In all this I forgot to check what the engine temp was doing). The NRMA patrolman guy though it might be a slipped timing belt tooth (he also though the oil cap was were you check for water so not overly confident in his opinion). [yt]L3x-IarqB8U[/yt] After getting it towed home it now makes this sound (after another hour of cooling down) which is almost normal and is a lot quieter. [yt]SlTn2qduKnA[/yt] The NRMA tow truck guy who towed me home (regularly races at Sydney Dragway and has built a couple of 6 litre turbo engines or so he claims) sounded a lot more knowledge than the NRMA patrolman guy, reckons it's the water pump bearing. So what do you all think? Next question assuming I can't get Andrew ASR or UAS to fix it before this Sunday's drag race is there anyone on the forum who can do it (for a fee of course). Would prefer a pro mechanic first of course so will try Andrew and UAS tomorrow.
