Manuals today suck...there's less than 2% that buy them, There's no need for one unless you have a some sort of mental issue. The automatic in my gen3 is way better than the auto in my old tundra. Don't believe all the bs on these forums that you only need a manual.
Btw, my brother has hauled...
Imo, you don't even need a truck, get something like a rav4, or even a ford frontier if you must have a truck. My brother has been very happy with his hybrid rav4, averages 30 mpg...plus their all hybrids, or ev's by now.
Leak down test is not just about coolant, it determines if all your cylinders valves are sealing well so your not slowly losing compression over time. Just by doing a regular compression test won't show that.
It's also not unusual to see some blow-by at that mileage. Engines get tired to.
Gotta get a wand, and spray the frame insides...thats how they begin to rust through with these tacoma's. I remember it being a real messy job on my gen3.
Time for a compression, and leak down test. That will tell you how healthy the engine is, but at over 300k miles don't expect a miracle.
All I can tell you when my gen1 tundra had close to 300k miles, its oil pressure wasn't as high at idle as it was when it had 50k miles. Internal engine parts...
When applying straight cosmoline like that, it needs to be thinned down so it creeps into all crevices like rp-342, or the crc marine heavy duty corrosion inhibitor.
I've seen so many cases like this over my lifetime. You still don't get it that your engine is tired along with many other parts like the fuel system that supports it. Time for a new truck, or live with what you have throwing more in it while getting no results. It won't get better if thats what...
Thats what happens when you have continuous blue state governors. I blame the residents of those states for having a low iq when electing them. Much of the ones with a brain have left.
Hundreds of fraudulent hospice centers for one committing medicare fraud, found taking our taxpayers dollars while living like kings. The doj claims we currently don't even have enough prosecutors to handle it all.
Its hard when you can't come to the realization that a clapped out high mileage engine has to be pushed harder to do the same work requiring more fuel in the process.
