The truck is perfect no rust whatsoever. Im gonna keep the engine and hopefully just replace the timing components. Timing has jumped 28 degrees so Im just hoping it hasnt done any internal damage.Kestral wrote:Is the rest of the truck in good shape? little or no frame rust? if so it is a good solid platform to build upon. Instead of dumping the engine with 25K why don't you just replace the timing chain and gears?
finding out you have bent valves/piston damage would be a very wise moveselliott wrote:The truck is perfect no rust whatsoever.

That is the plan and my main concern also why it's been sitting so long, I just didn't want to deal with it.eieio wrote:finding out you have bent valves/piston damage would be a very wise moveselliott wrote:The truck is perfect no rust whatsoever.

i'd invest in a leakdown test before doing any repairs on the engine

what happened to the leakdown test, or at least a simple compression test?selliott wrote:ok so now im stuck and confused. I pulled the timing cover yesterday expecting to find worn out guides and or tensioners but they are perfect not a mark on them, chain is tight and looks good so i have no idea. Nissan said the timing is 28 degrees off which im not sure how things are supposed to be lined up to tell how far its off. So essentially i have it torn apart and have no idea what to do. Since I have it apart should I replace everything with the new "redesigned" ones? Could this be a computer issue?
After fighting random engine codes I took it to nissan and they said the timing had jumped and their recommendation was to "remove timing cover and replace components"eieio wrote:how do you know this?selliott wrote:The truck is perfect no rust whatsoever.

i havent done it yet, I figured i was gonna have to pull the timing cover anyways so I started there. I have the leak down test sitting in the garage i just havent done it yet.eieio wrote:what happened to the leakdown test, or at least a simple compression test?selliott wrote:ok so now im stuck and confused.

Thank you and no i didnt and its been sitting for a year till i had the funds to fix it.eieio wrote:the service manual should have the info to verify the timing once the cover is off

did you ask the dealership how they determined that the timing was 28 degrees off?
