Not much to talk about really just a whole bunch of parts. Matt @ Import Motor Werks did all the disassembly and assembly and I just stayed out of the way mostly and did all the cleaning and prep tasks. This was very time consuming and if I was to plan this differently I would do the starter replacement separately.
Laying out all the parts for visibility.
With all the coolant drained Matt evacuated the R134 refrigerant to get the AC lines out of the way and then proceeded to get the clutch fan, radiator, harness etc out of the way to tackle removal components up top, intake manifold, valve cover, timing belt covers etc.
Again the CUDA was used to get everything clean, before it was put in the parts washer I sprayed it down with a degreaser and agitated everything with a brass brush just to help things along and boy did the valve covers clean up nicely!!
Starter, coolant by-bass gaskets and all electrical connectors replaced
Cam seals, crank seals, water pump, timing belt, tensioners and pulleys replaced.
Addressed the intake manifold, cleaned up the mating surfaces for new gaskets.
Removed the injectors to get cleaned as well and replaced with all new O-rings.
New fuel pressure regulator and lines.
Everything coming back together.
Of course can't leave out the tee's and all new lines to go with it.
After the fan clutch and radiator was replaced and with everything buttoned back up the truck was left overnight so the FIPG can cure and the next day coolant was filled and bled. The O2 sensors were replaced as well.
Was everything necessary? I had a check engine light on for a lean code due to the O2 sensors. With everything apart Matt did point out the timing belt tensioner was failing since it was leaking hydraulic fluid so just that in itself made it worth it. No other leaks from the crank and cam seals. There was a slight leak from the valve cover gasket but everything else seemed good. So was everything necessary, no but the "while you are in there" mentality drove me to plan for everything including connectors which could break due to age. For now I have peace of mind that this should be good for awhile! So that makes it worth it for me.
Huge thanks to Matt again for doing this!
