Need advice from the RTOC with ref to a friends C1J engine GTT that has broken down tonight.
The symptons are as follows, the little R5 GTT sounds like it running is on three cylinders but on 1 of the engine strokes whilst it is running @ idle there is a clonk that causes the engine to vibrate ?(Quiet alot) The clonk sounds like it is coming from the bottom end. There is no loss of coolant and no mayo and all 4 sparks have good spark and are in the correct firing order 1342 the fault developed whilst the car was being driven there is also no leaks under the car. Any ideas?
