So this is a continuation from my Turbo V6 thread... I took my 4.3 V6 and made all the mods to make
into a little screamer.. Somewhat successfully..
Problems arose.. The truck RUNS awesome, it's tuned well, pulls hard and I am happy with the mods I did. The happy stops there..
When I purchased the truck the guy really sold me on it, mostly because of the "new" engine, he provided a build sheet from a local machine shop that showed it had been rebuilt and was new.. Well as things have proven it may have been rebuilt but not very well and things seem sketchy at best I got the truck it ran fine, lacked power, had what seemed like great oil pressure, so I thought I had a solid platform.. nope..
The first oil change I did on the "fresh" engine was with Royal Purple 5w30 I changed the oil all seemed well and I took if for a spin, truck runs like a scalded dog, as the engine heated up to normal temp the oil pressure lowered.. to the point that it has ZERO at idle. I could hear a slight rattle in the lower end but with these engines balance shafts which are known to make a noise I was hoping that was what I was hearing..
I changed the sending unit.. no luck..still low I looked at the new oil it was fine.. Luckily I kept the old oil for recycle, so I looked at it and it was very thick in comparison even after it had been ran in. In a last ditch effort, I went and bought 5 quarts of 20w50 Valvoline, changed it, pressure came up I was relieved, then I drove it and once again at idle 0 and the noise came back.. I don't know what kind of oil they had in it but this "fresh" build has way too much crank clearance and needs pulled out and corrected. Shady at best. The truck was never ran lean and no more than 8lbs of boost... I started with a turd with a build sheet..
So I start searching for rebuild solutions and quickly came up with the fact that for a mild rebuild with good cam, valve springs I would have a hefty price tag. I cant justify a new build and keeping it a v6. So although the V6 was fun, and runs AWESOME the idea is now officially scrapped.. (for this this truck)
