Confession?

I’d consider swapping the timing chain. I was amazed how stretched mine was on my original engine.

I'm wondering if reusing the timing was even a consideration to Marco. The FSM usually gives an inspection criteria for the timing chain acceptable stretch but it never made sense to me why a mechanic would go to all the trouble of tearing into an engine just to measure a suspect chain (be it miles, age or just being unknown) and even entertain the possibility of putting it back in.

"Oh, I see 17 links on this chain comes in at 1mm less stretch than the maximum. I think I'll put it back in and repeat all this work in 6 months," said no one ever.

I actually never even came close to considering changing (or even checking) the timing chain. I peeked in there and saw the guides still in place, and knew that the PO had done the seals up front and was done with that part of the motor. If I was staring at the chain of course i'd change it as a matter of course, as Dave says, no real reason not to. I don't think I've ever reused a chain unless it was a head job like this where it was still buried honestly. Anyhow retarded cam timing improves top end right?! I probably won't even take the oil cooler off even though 'mud says you must and I have the gaskets lol.

Measure. Mine was within spec at 225,000. We did the the guide slipper

Finally got some time in the garage in between travel and finished lapping the valves, got the new valve seals installed, and installed the valves in the head. Ready to throw cams on and see how far out I got with the lapping.
BTW if you’ve never used a valve master tool and you do Over head cam motors you gotta try it. It’s awesome.
I finally feel like I’m past halfway on the head job.

Rebuilt a power steering pump that I got from Ray (Thanks Ray!)and it’s ready to go in. I just figured I’d rebuild a spare so I could just swap them.
Also got a new gear since I had a weird knock noise that went with engine RPM that I suspected was a dinged tooth or something on the gear that’s in the motor now. We’ll see I guess!!!

 

[rover67]

The head is ready to go back on but I want to do the power steering pump and hoses as well as the fan clutch while it’s off since I have more space that way.

Marco, if a replacement chain for your engine comes with a master link, it really would be a piece of cake to attach the new chain to the old one. Turn it over by the crank bolt, out comes the old and in goes the new. Then put the head on.

That’s a really good point!!!!

I went ahead and replaced the power steering lines since one literally snapped in half when I pulled the reservoir off.

It also looks like somebody just used a three jaw puller on the old power steering pump gear. It has some decent dings in it in three spots around it. I’m pretty sure this is where my knocking noise was coming from. I’m actually excited to find the damage and replace with the new one..

 

[rover67]

It looks like a mess but I got the new power steering hoses all on, the rebuilt power steering pump on, the new belts set on there, new water pump on (old one was weeping), and one new idler pulley on. Waiting on a bearing for the AC idler pulley. It gets here tomorrow. After that’s done and the belts are tensioned I’ll get after the head install! W00t!!

PS, if anybody was wondering the timing chain measures out to be in spec by a country mile.

Looking good!

Not to add to your paranoia about or to question anything you're doing but I'm definitely going to keep up with how much luck you get from those power steering hoses. I'm told that OEM hoses are the only ones that hold up but that's hard for me to understand. I totally get it and have personally experienced it on other components but hydraulic hoses are simply a matter of good rubber and a good crimp on a good fitting. I've worked around hydraulics my entire life and have seen plenty of well made, non-japanese hydraulic lines stand the test of time. My point being is that a high quality aftermarket hose set should last as long as an OEM set in my mind.

 

[rover67]

Are you talking about the High pressure hose? It's actually Japanese!!!! Assembled in China though, so I must be hosed.

at 225,000 mine was "in spec" so you say "in spec by a country mile." I looked that up in the FSM "Roughly speaking a country mile is 10 furlongs (2200 yards) whereas a mile is 8 furlongs (1760 yards)." Informally "a very long way"

I'm told that OEM hoses are the only ones that hold up

My original 1993 hose lasted till 2011, with some weep towards the end, but really minor. A Gates high pressure line ($69.00) lasted April 2011 - March 2014. It weeped a bit before I replaced. My Toyota OEM ($196) is from March 2014.

is currently weeping at the crimps, but just enough for dust to gather around them. It’s been on there for 2 hard years.

Continuing down the path of PM on my 80, I'm thinking about replacing the soft brake lines. Should I look for something better than Rock Auto?

Oh, and Marco, take a look in cyl 2 before you put the head on

 

[DaveInDenver]

Are you sure Rock Auto will even ship to you? They won't to me on account of living within the city limits of Grand Junction.

 

[SteveH]

Quality-wise, I have used the Rock Auto replacement soft brake lines on several Toyotas with no issues.

was that a pun? good one.

Neither Bruce nor I live in Boulder. We live in unincorporated Boulder County.

I guess we'll see if the Rein Hose lasts. who knows

it was! Thanks!
