I've been looking for a project

Recommended Posts

Where is the best place to get torque specs?  I’m installing my front brake calipers?

I don’t know why I didn’t notice this during disassembly, but my front right caliper has lick washers on it and the left do not. Should I install lock washers on the front left?

I've used 30ft pounds for the caliper to mounting bracket bolts for both my `90 Camry and my `80ZX.

They both have similar front caliper designs, so I used the Toyota spec. for the Z.

I'm curious to know a torque spec. For the Z as well. Too much torque on those caliper bolts can be problematic.

Are you on lick washers or torque specs?

Torque specs are at the end of the Brake chapter.  Service Data and Specifications.

Forgot to say, CZCC has the FSM's on the site now.

It's not in that manual. 

Humm... I don't understand that - it is in my Factory Service Manual - Page BR-12 Caliper attaching bolt 7.3- 9.9 (53 to 71 ft.-lb)

Then again on BR-27 Service Data & Specifications - Caliper to knuckle flange 7.3 - 9.9 kg-m (52.8 to 71.6 ft-lb)

Any ideas what this little gem is.  It's made of steel, and was found in my oil pan?

This was also found in my oil pan.  Looks like one of the seals?

The sludge in the bottom of my oil pan has a silver tint to it, is this an indicator of anything I should be concerned with ?

The first looks like a valve lash cap. 

Silver is bad!!!! Put a manet in that and see what happens. The last time I had a similar situation, I destroyed a camshaft. Might be bearing material though...

I had a magnet in the oil pan. That spring thing from the seal, and that other piece are all it picked up.

Perhaps the PO put some sort of "engine restore" substance in it.  I've never used anything of the sort, so I'm not sure what it looks like, except for the types in clear containers sitting on the shelves at auto parts stores.  They look to have some metallic qualities.

It looks like ground up aluminum.  I bought an old mystery transmission, filled it up with some old fluid and spun it on the back of my garage engine.  The fluid looked like that when it came out.  Ground up shift fork. 

With the lash pad, the seal material, and the silver, kind of looks like a camshaft might have damaged itself in the past.  The camshaft tower bushing journals are aluminum.  The cam rides right on the tower material.  Lots of aluminum in other places too that could get rubbed on.

Are you sure that's a lash pad?

Am I looking at a rebuild?   Any recommendations in Northern California ?

Not really clear where you're at on the project.  Could be that somebody already rebuilt the head and those parts are from the past.

How does the head and valve train look?  I haven't looked back through the 7 pages.

Good point.  I can check to see if all the lash pads are in place.

My goal was to be driving this thing within the week.  Kind of bummed   right now.

Not clear what you're bummed about.  Old parts in the oil pan are pretty common.  People find all kinds of things in there.
