Diesel’s having a ping fit
In my 2007 Nissan Navara, the 2.5-litre turbo diesel stutters or hesitates and makes a pinging noise when it’s cold but it’s OK when it’s warm. I have had it to two mechanics and they couldn’t fix it. What do you think is wrong?
Kevinromano Check the injectors. Your problems are most
likely there. JUST HANDLE IT How can I improve the handling of my 2010 Nissan Maxima?
Andrew, email Nissan specialist Jerry Newman is horrified at the thought of trying to improve the handling of the Maxima. He believes it handles well as it is and is better left alone. If you were to seek to improve the handling, you could fit uprated springs and struts but this would be expensive. Use quality components from the likes of Pedders. Perhaps you could check the web for components used in Japan but you must understand that whatever you do will have a detrimental effect on the car’s ride and you might not improve the
handling much anyway. ANNOYING LEAK My Subaru Outback 2.5 EFI has developed a slow leak at the rear of the engine between the head and the block. I have had it pressure tested and that’s the only place it’s leaking from. It doesn’t overheat and there are no bubbles in the radiator or water in the oil. I have had the water pump, radiator hoses and radiator checked and there are no leaks. I have had three independent reports by mechanics that say the same thing. To fix the problem, it’s necessary to pull the motor out and I have been quoted $2800 to $4800 to do it. It has done only 176,000km and I am pretty dirty at having a head gasket go at this relatively early stage. Any suggestions for a fix?
Alan, email I would try Bars Leaks or a similar product and hope it seals the coolant leak. To replace the gasket, which is the best fix, you would have to take the engine out as the mechanics suggest.
