This is a pretty nice engine core. The owner desires it to be
refurbished to just like new using as many stock parts as possible.
|
|
The stock serpentine damper/balancer is banged up a bit.
|
|
|
|
Before removing the intake manifold I cleaned and blew out with air
the debris. That is so that I can identify debris that may be in
the engine and I don't want to mix that up with dirt that I caused to
fall into the motor.
|
The intake valley looks great. No debris. No bearing
dirt. No sign of head gasket leak.
|
Rocker/valve springs look good and the heads look good.
|
|
|
|
|
|
Water in the oil pan but that is not enough to be from a head gasket
leak. That is from condensation. The oil pan is free of
debris.
|
Crank and rods look good.
|
|
|
|
|
|
Pistons and rings are all in good shape but the rod big-ends are
egg-shaped which is pretty normal. The rods will be
reconditioned.
The mains look good.
|
|
|
|
Piston bores look great. A mild hone is all that is needed.
|
The cam bearings are in good shape too.
|
|
|
|
All items are now back in my shop after a nice stay at the machine
shop. Block is painted and cleaned.
To the right is the photo verification that the oil galley plug, (in
this case a steel ball), is installed.
|
|
|
|
Stock crankshaft was polished.
|
|
|
Using Clevite "P" series bearings, (conform well to soft
stock main caps).
|
|
I set clearances on the tight side of the spec. since this is a
stock rebuild and not a high rpm race motor.
|
|
|
|
New cam bearings shown to the LEFT:
Big Block Chevy oil galley plugs with oil holes shown above which take
the place of the stock plugs.
|
|
|
Main bearings set up for long-term-storage via the assembly lube.
|
|
Brand new Cloyes stock LT1 timing set.
|
The Cloyes stock timing set is a bit different than stock in that
the cam gear is billet.
|
Valve train parts cleaned. Lifters soaking in 30 weight oil.
|
Crank rod journal at 2.0991"
|
Rod bearing clearance at 0.0024"
Notice to the right that I use an ARP rod bolt guide tool to install
the piston/rod.
|
|
|
The block was not decked, (just
cleaned). This shows that stock deck height is around
9.025". The piston is in the hole -0.025"
|
|
Rod bearing clearance 0.0020" with King CR807SI
bearings. Standard size.
|
The crankshaft rod journal is 2.0991" (for the records).
|
|
Crankshaft endplay is 0.004" and rod side clearance is 0.012
to 0.016"
|
New Melling M155 oil pump. I need to get the 3/4"
pickup.
|
|
Heads had a mild valve job and deck straightening.
|
They also received new stock valve springs.
|
|
|
Heads on and new stock head bolts torqued to 65ft-lb with thread
sealant on the threads and ARP lube under the bolt-head.
|
|
|
|
|
Lifters-Rockers installed and adjusted to
1 turn past zero pre-load.
The timing cover was cleaned and new
seals were installed, (water pump, opti and crank).
|
|
Here is the new 3/4" oil pump pickup.. I'll explain how
I accomplish the task of pressing it onto the oil pump.
|
Here are the tools. I freeze the pickup and heat the oil
pump after removing the relief spring. I have no idea if heating
the pump with the spring in place will change the tension of the
spring but I remove it anyway. The tool on the vice is designed
to allow me to hammer the pickup into the oil pump.
|
For this M155 oil pump I changed the relief spring to the GM
#3848911 for higher pressure.
|
F.Y.I.: I'm not a fan of
welding the oil pump pickup. The factory does not tack weld
it. The pickup will move if you hit it hard enough but that is a
moot point when the oil pan is installed.
