1) When i saw the vehicle I noticed that there was a slight oil residue around the turbo of the engine, should this be a cause for concern?( Granted that the engine had been washed before me viewing it) I spoke to a mechanic and he informed me that this is a normal occurrence and that I have nothing to worry about but I am not sure.
It's a known fault in the WLT engines (not so much the WL's) in both Ford Rangers & Mazda B2500's (maybe even the newer BT-50's). The head tends to crack after approx 120,000km or more - usually to poor cooling system maintanance. Easiest thing to do is check the exhaust while revving the engine, look for white smoke (sign that water is in the combustion chamber) and you can also check the radiator levels on consecutive days (if he allows you to) as long as you know the radiator and hoses aren't leaking.2) Upon doing some light reading on the forums i have discovered that the instance where the engines often go bad, Is it for the WLT only or both WL and WLT's have an frequency of going bad at various points in time. can anyone estimate the amount of mileage that would be have to be incurred on the engine for such a problem to arise. "DO ALL MAZDA ENGINES GO BAD?"
Also whats the price range for a new engine?
3) I want to know also, what can be done on my part as a form of "preventative maintenance" to mitigate or if not stop such problems from occurring within the period that I may be the owner of the vehicle?
4) Are there any other known problems with this type of vehicle?
Trim wrote:So guys, I drove it a couple times and its a real comfortable driving van. However I discovered that when I really decide to accelerate with the van on open road, the temperature gauge shoots up like crazy. This happens especially when the air conditioning is on full blast. however, when I decelerate, or come to a complete stop and turn off the ac, the gauge returns back to normal,( it takes about 30- 40 seconds the most)
What do you think may be the cause of that and how do i rectify the problem?
I checked the oil levels and its quite normal i am not seeing any of the symptoms outlined for a bad head.
Any assistance would be greatly appreciated thanks!
