Hi guys, bit of advice needed here (1990 TP EFI):
I was getting paranoid about my timing chain (140k on it) so I decided to call my mechanic and ask him how much it would be. He reckoned around $800 all up but only to bother doing it when it was making noise ALL of the time, not just on startup. He also said that even after they replace the chain and guides/tensioners, they sometimes still make noise. Usually the solution is to use an oil additive called moreys which coats the guides and makes the chain run smoother.
Anyway that was kind of interesting and a bit of a load off my mind so I asked about my oil light coming on and off at random intervals. The guy said that it could be quite serious because lack of oil pressure can be a sign of premature wear/problems in the big end and/or crank bearings. So now im quite freaked out about the fate of my engine.
I read most of my workshop manual without finding a reference to the oil light and what could make it go on and off (short of a faulty sensor which I will investigate in the next few days). My other thought could be a dirty/clogged oil pickup screen. Has anyone had a case of the oil light coming on and off? What was the solution?
Oh and yes I HAVE CHECKED THE OIL LEVEL haha.
Thanks guys.
