I get what you are trying to say. Everything and every component fails due to wear and tear, heat expansion, contraction, mileage, neglect, abuse, poor workman ship, poor engineering, etc. If it falls out of warranty for that manufacturer and there are a limited number of reports...
If there were for example? 5 million 2GR FE motors built by Toyota for one production year across several models and manufactures, and say only 5000 of them failed? And failed out of warranty or over the warranty mileage? Its a wash! I get that. 5000 out of 5 million isn't that bad. And yes! All things fail with time. I get that!
But what happens when you have an engineering issue that affects say? 50,000 out of 5 million for that production year. What recourse do you have If several manufactures and their respective dealers don't stand by their product and reputation? What do you do when they allow it to continue?... FROM NEW! ACROSS MULTIPLE MODELS AND A WHOLE RANGE OF YEARS? Isn't that the point of TSB's and recalls? Isn't it the owners duty to document, diagnose, and complain. Otherwise not enough numbers of complaints get generated to take action.
Lets get this and my intentions straight. I don't expect anyone to do anything about this especially that I am way out of warranty. My vehicle has 212k from when I purchased it at 167,500 k from a year ago. Its a 12 year old vehicle. I don't expect it to perform "like new." I am simply trying to see if I can mitigate the situation by trying different oils with different additive packs, or different oil weights, just to see of it will quiet the situation and possibly have no consequence, and or possibly prolong or get as much out of the engine as possible. I've only had the vehicle a year, abd I am slowly becoming more aware of its quirks, despite it being boasted as a reliable engine. From the info I have gathered here and other forums. Its definitely a mechanical fix that has to be dealt with that no oil can solve.
I don't expect anyone to do anything about this other than myself or a qualified mechanic taking action.
Here are my sources related to all these issues. Its widely known. Well documented, and limited recalls have been issued on the matter.
