I finally tore into my engine swap today.

Woulda had the thing completely out before dark but the roomie didn't bring the cherry picker home tonight like he promised. (He's heading out early tomorrow morn to get it) While he's out running I'll be working on removing, cleaning, painting, and installing the timing cover, so I can install the head on the new engine.

Once the old engine is out, I need to swap the oil pan/pickup, and then it's in with the new. If all goes well, I'll be up-n-running with my 22r hybrid this time tomorrow!

(I did notice that I had a headgasket leak tapping into 1,2, and 3, but not terribly bad.....just a sliver of the pistons were steamed clean...the rest was throughly coked with carbon.)

Photos tomorrow. ( damn I forgot how much FUN wrenching is! )

 

I went from THIS
To THIS




Photo of the old block, head off.


You can see on the intake side where ALL FOUR of the bores had bad HG seal. #4 was the worst, and had the least build up due to steam, but you can see the 'sliver' of clean piston on #'s 1, 2, and 3.

Looking back it appears the engine was just fine....it was simply a combination of the buggard vacuum advance, and the blown headgasket that was screwing up my power/economy.

Oh well... I have a Hybrid now!

 

VERY nice!!

Make sure to properly break the cam in. Don't crank the motor over to until oil pressure rises. This is a common mistake and WILL destroy, or severely reduce the life of the camshaft. The motor must fire immediately.

Also, there has been a big problem with camshafts "wiping lobes" due to the fact that the critical anti-wear additive, zinc, has been almost completely removed from all motor oils since modern day (late 80's to the present) vehicles have been using roller rockers, which require little to no zinc. Zinc has been shown to be a little hard on cats, so that gives yet another reason for the EPA to phase it out

Zinc is a critical additive needed to properly break in a camshaft, so it's important to add GM EOS or STP's oil treatment to the crankcase. Shell Rotella is one of the brands of motor oil that contains higher amounts of zinc.

Good luck let us know how it runs

 

No worries. I dug out some leftover Mopar Performance Cam Lube that I had leftover from another build.

Lubed the lobes, bearings, and even glooped some on the timing chain.

She runs just fine, aside from the fact that my vacuum advance isn't functioning. I'm just waiting for th break-in to be done with so I can swap on teh Weber 32/36 I have sitting on the shelf.

 

phss,

watch the thread titles good luck!

What was wrong with the thread title?
