Also being an engineer...Originally Posted by apalsson
While I appreciate that people have had issues with high EGT in the past, especially in the early versions of the ZD30, I admit I'd be seriously reluctant to apply heavy handed fixes that we all agree are illegal too.
Are there any statistics available that show the percentage of these engines (year by year if possible) that actually have failed because of excessive EGT?
Even better, with the cars that blew engines, what was the configuration? (did they have bullbars without adequate openings at the front, high mount winches or other mods that might have contributed to overheating)
I guess being an engineer, I have limited imagination but like to go on numbers (facts and figures)
A blown engine is no joking matter but neither is voided warranty on a new engine or a defect notice from the boys in blue
Reliable figures? ... Hell no
Configuration? ... again Hell no
It is almost impossible to even find reliable sales figures of how many Patrols of a particular series have been sold.
Forums are probably one of the least reliable sources of information as regards statistics (I stress statistics) as well because they do not attract an untainted sample statistically speaking. Most people "find" a forum because of a personal interest over and above Joe Public or they have had failures... the old "search for shit and you will find it" syndrome
The vast majority of nomads, soccer mums etc tooling around in their Patrols wouldn't have a clue about blown engines, cleaning MAF's or whatever because while it keeps going they don't care.
The other BIG issue with forums is that a single post that is absolutely 100% wrong can get a cult following and become absolute concrete fact that an exponential number of people will swear is kosher purely because others have done so and it becomes almost impossible to contradict or correct.
I've seen it on other Forums and also here and I rarely even bother trying to correct it these days as you either get flamed, argued with or ignored
