Builds Reconstruction after rollover - building The Champ 2. (2 Viewers)

[baldilocks]

Meanwhile, in my garage, Toyota continues to live up to it’s reputation based on what this crank and main bearings look like at 238k miles. There are a few marks that I can catch a finger nail on mostly on number 6 and 7 but nothing, in my amateur opinion, that will dictate grinding the crank. Same with the bearings.

After turning the engine upside down there was coolant coming from #7 exhaust port and #6 intake port. This seems pretty whacky as I didn’t notice any indication that the HG was blown. I didn’t drive it a lot since I bought it due to the massive oil leak but I drove it enough and hard enough at times that I think I would have known the HG was toast. Maybe it was a very slight leak. This is not a hurry up project but a project I’d like to enjoy while taking my time.

Three of the rod bearings don’t look so good. Rod journals are fine. #1 rod journal is pictured below. It looks great but its bearing is the worst of the six. Why do some bearings pit and gall while others look fine?

Yikes! The PO, who had this 96 since 99, needs a few lashes! The deeper I go here the more pleased I am with my decision to do a full rebuild. The cooling system was full of what appears to be newish red coolant. The radiator and all coolant passageways, including the oil cooler, have looked practically new.

Doing work, Steve. Let me know if you need a hand. I’ll be waiting for you on the corner of Never and GTFOH.

Staying more than busy keeps me out of trouble; I could use some advice along the way if nothing else.

I’ll hit you up, it’ll be good to catch up.

I've never understood that either. It's definitely been a factor in engines I've torn down that have gone longer between oil changes. I've always assumed there's a luck component to how the wear starts - Some small piece of debris gets pumped in to the journal and starts chewing one up, which just snowballs. If the engine had been suffering from low oil pressure for a long time, all of the journals tend to look more evenly thrashed.

I got the engine back from the machinist a few weeks ago and today I’m finally starting to put the engine together. He built the head and short block. The rest is up to me with the help of the FSM and you all. First is the timing set and cover. Chime in if you have advice.

So over the last few months I’ve made 4 big orders from PartsOuq and right out of the gate I’m minus the front crank seal! I’ll hit up the local dealership on this. Edit: as it turns out I forgot about the gasket kit I had ordered which includes the front crank seal

Ready for the cover.

Looking good Steve ! It's gooing to be sweet.

I thought I was organizing my hardware during disassembly. I did but still struggled to find the exact fasteners to attached the time chain cover. That’s done so on the way out I made a map. Do this prior to sealant:

Test fit the timing chain cover. Recon all fasteners. Toyota sealant is easy to work with.

Are you going to order a turbo from Cruise and Company ? You should

Great People/ company I wheeled with them at Cruise Moab

I’ll be installing this turbo oil return fitting into the oil pan as a precursor to a turbo install. Will I do it? Only once the new package operates as it should.

Pulling the cams to install the head after the machine shop pre-lubed the cams seems rather silly.

But how else would the machine shop know the correct lifter to cam spec.

Oe within spec

Any chance you saw the old timing chain guides & had the plastic inner of either pulled loose of the metal arm?

Miles on motor as you were breaking it down for machine work?

Just curious - long ago Christo said that was common but not a serious problem as the plastic stayed close to where it was on day 1, it just dropped a bit but chain still held it where it acted like the guide works.
