Title: 28 Q engine info
Post by: rwollman on March 27, 2018, 06:13:53 PM
greetings all - looking for any info on torque specs  on rods and mains for above engine.  After doing cylinder leakdown test it was confirmed that rings are collapsed and/or worn.  I have located pistons and rings from Hagans Auto in Washington and Melling cylinder liners for the engine.  Plan of attack is to pull head and mic the bores to see how bad things are.  If not toooo bad will ball hone cylinders to break glaze and install new pistons/rings.  If too far gone then out she comes.  Would like any info regarding torques if at all available.   
thanx in advance for any info

You might want to check an old Motors Manual from the late 20's or early  to mid 30's.  And look at the Maxwell 4 cyl.

Not on topic; I don't want to be a spoil sport, but you may want to check flatness on head and block before reassembly.  I don't know if ever done on my rebuild.  Good luck in your endeavor.   frank
