Our 1993 Bonneville was purchased new by my wife'* grandmother, driven for five years by my wife'* mother after grandma passed away, and has been in our hands for the past 10 years. A Bonneville of this vintage is not a collectable, for sure, but ... there'* some sentimental value, the body & interior are still decent, and we need it for a fourth generation of drivers.
Having said that ... a couple of rod bearings spun after 20 years & I tore the engine down. The cylinder bores look almost new and the cam is in good shape. The crank has light scoring & has been polished to improve its condition. I'm going to put it back together with new bearings & rings & try to get a few more years out of it.
My questions revolve around GM'* threadlocks, sealers, and lubricants "or equivalent" as specified in the factory service manual.
After reading other threads here, do I have this right:
Threadlock GM p/n 12345493 = Loctite Red 272?
Rear Main Cap Sealer GM p/n 1052942 = Loctite Instant Gasket Eliminator 518?
Intake Manifold Gasket sealer GM p/n 1052942= Loctite Instant Gasket Eliminator 518?
Cylinder Head Bolt Threadlock GM p/n 12345382 = Loctite Blue 242?
What are the market equivalents for ...
Jacket Plug Sealer GM p/n 1050026?
Cam Lube/Valve Lifter pre-lube GM p/n 1052365?
Thrust Bearing lube GM p/n 1050169?
Cylinder Head & Front Cover Bolt sealant GM p/n 1052080?
