My 1997 SR5 build and repair thread

[19963.4lsr5]

Oil pan tomorrow before work. I had to chase the threads for all the oil pan bolts and one oil baffle.

You're doing great work. That's going to feel so good to turn that key and listen to it fire up.

Nice! Thanks for all the pics, the engine is looking great.

Oil pan is on. I’ve had the oil cooler soaking in a pail of acetone for a week. I’m going to fashion up something to flush it with motor oil or mineral spirits. I got all kinds of coked oil out of it with the air nozzle. It needs done or a new one. I’m not putting it back on seeing the crap that blew out the ports without flushing it.

Ran an entire gallon of mineral spirits through the oil side of the cooler to flush it.

Oil cooler is on with new hoses and clamps. Heads are on block. I will torque them down tomorrow. Then it’s time for cams ad valve shimming.

Heads are on and torqued down. Doing the final 90 degree rotation some didn’t feel as tight as others.

So I screwed up. If you notice in the picture I put the darn heads on the wrong side. So, I get to do it again with new gaskets (should be here tomorrow) and headbolts from YotaTech.

Better to have figured that out now than later, right?

Yea, I went to put the cams in when I figured it out dam it!

Why in the world does Toyota use odd ball bolt sizes that make it difficult to find taps and dies locally? Aka 7mm cam bearing bolts and 11mm headbolts.

Happy day!

I made sure all the head bolts thread in and bottom out with my fingers smoothly.

I still have the oil smell on my hands from oiling the washers and head bolts

I also checked the dowel holes in the heads and one had a pinch gooner from me not tightening the head in such a way that the head doesn’t bind on the alignment dowels. Plus another hole in the other head had carbon build up. So I bought some wire brushes for copper pipe and got everything cleaned out aka the pipe brush for copper pipe and de-bured aka the gooner/ridge on the one head and removed the coked oil on the other head.

Needless to say I busted ass torquing these head bolts and it was as expected the entire torquing sequence. I now have confidence in these heads being installed on the block Pete put together for me.

On an engine stand doing the final 90 degree torque sequence is a mofo by yourself trying to keep the stand from rotating with your foot while you get that last 90 degrees out of them head bolts.

Tomorrow I will install the cams and check valve lash. Hopefully I have what I need without ordering shims. I want this engine together and ready to install by tomorrow night. My work schedule sucks until they hire another electrician. I work a 12hr day and have to fill in for the missing man. (Missing man rotation is what we call it)

Cams are in. It took longer than I thought to clean up the bolts and threads in the heads. The heads were jet cleaned and there was a lot of residue on the bolt threads etc that needed cleaned.

I also used my oil squirt can and filled the cams with motor oil to help speed along the oil system priming. Along with major amounts of assembly lube

Tomorrow I’ll check valve clearance and go from there. I also want to put on the timing belt and harmonic balancer, and pull the 4Runner into the garage to pull the dead engine.

I liked the way the dots help with the cam removal/install, and then to line up to get the timing right. The 'service bolt' to keep the gears together while the cams were out...that was cool too.

Decent progress, here's to your clearances all checking out good!

Funny that my valve cover bolt on one of me exhaust cams kept the gear misaligned. I removed it and got the two halves of the gear lined up.

The cam Dots are necessary to install the cams without screwing up the threads on the cam bearing bolts. Trust me when I say that if you do not remove or install the cams on the DOTs you will most likely pull the threads out of the head and require studs or heliecoils to repair them.

It’s time to figure out the shims for the out of spec valves.

All valves are adjusted. Time to install the valve covers and coolant bypass tube and the timing belt. It’s slow only working on it one hour a day before work.

It’s lookin like an engine finally.

Hopefully tomorrow before work it has the timing belt on.

I love the harmonic balancer tool. Looking like more like an engine every day. 217ft lbs of torque is a lot.
