[[UPDATE: after wasting money on valve stem seals without fully investigating what the issue definitely was, i finally took off the right side valve cover which has NEVER been taken off..i found the the rear oil drain hole (theres 2, 1 in the front 1 in the back of the head) was plugged with fiber which is from the 10 year old air filter i had been using..so basically the ENTIRE valve cover was filling with oil force feeding oil into the cylinders. Goes to show, routine maintenance is not a joke..i figured an air filter is an air filter, but i guess not lol.After 10 minutes of idling the Exhaust will start making blue smoke and it looks kinda like "Uncle Buck" lol. It VERY rarely smokes when i drive, only when i take off.
Replacing valve stem seals in 305 H.O. small block chevy from 1986 Monte Carlo SS
I'm putting the original 305HO back in the Monte after taking the ZZ3 out
for my Iroc project. This is mainly to make the car mobile but it may end
up tagged with this engine for a while. Previous owner reported that this
305 has over 100k miles on it and has been out of the car since 1997. He
said it smoked during startup and sure enough the valve stem seals were
worn out. Hopefully this will fix the issue.
Valve seal Replacement
Leaking valve seals cause your engine to smoke when you first start it up,
and then it usually runs the rest of the day with no smoke. Usually
replacing the valve seals will fix the problem. Here's how to do it. Of
course other engines may vary to some degree but the basics are the same.

How to Reseat / Lap Valves (Basic Valve Job)
In this video i'm explaining how to reseat or lap valves in a flathead or
overhead valve engine. Also can be called a valve job, but this is not a
complete valve job. I also used to much valve grinding compound, it does
not require a whole lot. Usually when a engine needs this done is when a
engine has low compression that is found to be leaking around the valves,
or sometimes a engine will backfire do to the valves not closing
completely/properly. Thanks for watching.
Overhead Cam at 14K RPM
This video shows an operational cutaway of a BMW S1000RR — a 193HP
superbike — bumping against its 14,200RPM redline. A cam and valvetrain
at 118 cycles per second is an amazing sight (and sound)

This is a video I did for a project. In this video you see us replacing
seals and it also covers other basics like valve spring compression and
lubing your cylinder head.

Fixing A Car That Loses Oil
Scotty Kilmer, mechanic for the last 45 years, shows how you can fix a
car's engine that you keep having to add engine oil to. It can be as easy
as replacing a cheap PCV valve, or as expensive as needing a full engine
overhaul. Scotty shows how you can find out.
Chevy 305 burning oil? [solved]
[[UPDATE: It was a $0 problem. I assumed it was bad valve stem seals, but
i had never taken off the right side valve cover to fully investigate and
bought the seals anyway. I took off the valve cover to find the rear oil
drain hole (theres one in the front and back of the head) was clogged with
what i think it fiber from a 10 year old air filter i had been
using..Basically the valve cover would fill with oil forcing oil to find
its way down into the cylindars. So after i unplugged it, no more smoke!
Easy as that! ]] I knew it couldn't possibly be something as serious as
piston rings..it only had 53,000 miles on it at the time.

Adjusting Chevy V8 Valves, Hydraulic Lifters, Old School, Hot Rod, Rat Rod '48 Chevy,383
The peice of paper shows the cylinder pressure readings and their
corresponding cylinder number.
I have 400 miles on the engine so it may continue to seat in some.
I did a compression reading and No.6 was lower than the others. The
cylinders averaged 129lbs of compression and No.6 is at 116lbs.
Not a big diff but I thought maybe just maybe the the valves were a little
snug. The engine isn't missing,,I didn't check cam lobe lift. I just
eyeballed as it ran.
I had read where 10% difference is considered "ok".
Listen for the lifter to "Clack",, then when it does,,stop and tighten
until it stops,,then some Old Mechanics go 1/8 more of a turn tighter AND
some go 1/4 more of a turn tighter.
That cylinder will miss for just a second as the lifter adjusts internally
to the new setting.
The rags are just there to keep the oil from the other cylinders from
flying on us,,lol.
