Re: Signs of an engine overhaul?

There were 330 and 425 engines, switch pitch transmissions in lots of Olds through 1967. 1968 went to 350 and 455, no switch pitch. Externally all these parts interchange, not so much internally. That car sounds like a complete refresh of the drive train, possibly only a few new (plastic and rubber)...

Signs of an engine overhaul?

The 425 engine was never used in the GM motorhome, they used 455 or 403. However
they will physically interchange. I use the 403 emissions engine, which will run, and run,
and run with minimum maintenance on crap unleaded. Bruce Roe

Help what is this??

From that description, I think it just controls some accessory during cranking, not controlling cranking. Since it clicks, I bet the ign switch is OK, but the start solenoid current must also flow through the shift position switch to the solenoid. My guess is, that switch is out of adjustment, try m...

Re: Help what is this??

I do not see that device in the 66 factory service manual wiring. But is seems to be a relay, perhaps part of an anti theft option. Likely one wire comes from the ign switch and goes to 12V when turned to START. It would drive the coil hen starting. The other coil connection would be to ground thru ...

I hope the battery is connected to a maintainer. Bruce Roe

Engine Ignition Timing

Glad it worked. On many of my cars the timing mark was on the harmonic damper, mounted on a ring of rubber. When the rubber got old, the outer ring moved around making the timing mark useless. After a couple of them came completely apart, I replaced them on all cars with FluiDampers, can't come apar...

What to replace? - 1972 only 25,000 miles

I would get the trans apart and throw in new rubber clutch piston seals, $30 if you can do it yourself. At that mileage I would expect to just reuse all the hard parts. The rear chain cover is terrible for leaking oil, but throw away the cork gasket and glue it back for a cure. This VALCO has been u...

Re: Transmission cooler add on

Hello everyone I have 66 Toronado which I love driving long distances I was wonder what everyone thought were on adding a transmission cooler to keep the oil a little cooler and adding gauge My approach would be to keep an eye on the coolant temp, and improve the radiator if necessary. Those oil co...

Hello from Germany!

For a very small investment you should be able to restore that starter for a backup. The bendix is a cheap extremely common part, probably brushes and that copper stud from somewhere. I learned that lesson half a century ago, now there are more backup starters, alternators, and a few other things on...

Differential

Bruce, what is the reason for so many different gear ratios on the same car? Were there choices when new or did you just get whatever was in there? The difference between 2.2:1 and 3.15:1 is quite significant. I recently had a new rear end installed in my truck. The original 2.88:1 gears were no lo...
