Cylinder Head 201 - Radius Cut Valve Job
This video covers the complete valve job process that your machinist might
perform. If the 100 series videos didn't help you identify and correct a
problem with your cylinder head, then this is the next step. This video is
brought to you with permission from my machinist in full 1080HD, and covers
cleaning up the head inside and out, preparation and setting up a radius
cutter, cutting all 16 valve seats, valve grinding, and spans 3.5 hours of
actual work in under 30 minutes. There's nothing like this anywhere else
THANK YOU BALLOS PRECISION MACHINE. Thank you for the professional
explanation and execution of a job excellently-done, and un-precedented
access to your facilities.
A valve job is done by re-grinding or replacing valves, and then having new
seats cut to match the faces of the valves you're using. There are several
different machines that might be utilized to achieve this result, but the
process is the same no matter how it's done. There are seat cutters that
utilize cutting stones. There are valve seat cutters with 3 separate
angles installed 120° out-of-phase, and there are single cutters with all
3 angles (radius cutter) that cut with one blade in one pass. The machine
demonstrated here is a Sunnen VGS-20 Radius Cutter. This machine (now out
of production) produces a gradual curved seat that's superior to the shape
of a traditional 3-angle seat. While a radius cutter does contain the 30,
45 and 60 degree angles, it does so without leaving any sharp edges between
My valve selection includes Supertech 1mm oversized nitride-coated
stainless steel undercut and back-cut intake valves, and 1mm oversized
Inconel back-cut Exhaust valves.
Inconel is a high-temperature alloy utilized in marine and forced-induction
performance engines that can handle more abuse than steel can without
melting. The other characteristics of the valves which are discussed
typically yield bigger gains in airflow than simply using a bigger hole and
a bigger valve.
Why I did this to a perfectly-good cylinder head:
I changed cams. Because the valves were previously recessed during another
valve job 9 years ago, my valve installed height was increased and this
raised the operating positions of my rocker arms. My new camshaft
selection dictates using the stock valve install height. The only
solutions to this valve install height problem are to either replace the
valve seats, or install oversized valves. I opted for the latter.

No really guys, what can I type here? I just went on for 18 minutes
without shutting up. I apologize for deviating from my normal format, but

Blueprint 108 - inspect the deck
There's a reason why there are no subtitled specifications in this video
for the block. It's because they don't exist in either service manual, 1g
or 2g. You're not supposed to remove material from a block on the deck
surface because it has ill effects on parts of the combustion chamber
geometry, and alters your compression ratio. It can be done intentionally
in some cases for a desired side-affect, but if you have to deck a 4g63
head, it would be advised to use a thicker head gasket. The Mitsubishi
Multi-Layered-Steel or MLS gasket is slightly thicker than the OEM
composite gasket. Also, HKS, Power Enterprise, Cometic, and other
performance brands all make MLS gaskets that are .065 and thicker.
THERE IS ONE ERROR IN THE VIDEO. I said a block with .002" warpage is
junk. I was completely and totally wrong. While I don't wish to spread
misinformation, I don't think it's a big enough error to warrant re-editing
this video. I just wasn't paying attention. .002" warpage on a cylinder
head is the service limit before it needs machining. I meant to say
.02"... or two HUNDREDTHS (not thousandths) of an inch.
...and here's my justification...
A warped block to me is junk either way even if its minimal because your
MLS gasket will never seal unless both the head and the block are perfectly
flat. Trust your machine shop to get the values for how much is taken off,
and buy the correct thickness gasket for your machine work.
A factory head gasket (composite) is .051"
The MLS Mitsubishi gasket is available in the stock .051 and a .062"
Cometic makes gaskets up to .072"
There are some brands that go as high as .127", but I'd have thrown both
the block and head away long before then.

Well this was a fun one to make. I believe I covered everything but if you
feel I haven't please let me know in the comments below as well as any tips
you might have to add as well. I'm not trying to make a big deal about
"pound feet" or "foot pounds" I'm just trying to put that out there, the
important thing is that you get the proper torque and get the job done
right in my opinion, what you decide to call it is up to you.

Removing the engine on my 97 Riviera
Pulling the knocking 3800 supercharged out of my Riviera to make way for
the replacement engine. Came out relatively easy thanks to the engine
wiring for the most part is one harness that unplugs at the firewall.
Everything is in that harness except the starter, alternator and speed
sensor wiring. The AC compressor and power steering pump unbolt and can be
left in the car so you don't have to drain the fluid/refrigerant. The
biggest pain was getting the axis motor mount off, the bolts were pretty
rusty. The ironic part is those bolts have to be removed to change the
belts, which are so cracked and chipped I wouldn't doubt they are original.
The old engine will either be used for parts, or I may rebuild it at some

How to replace a crankshaft sensor on a grand prix gtp
This video is dedicated for the GTP owners that need to do the same
crankshaft replacement procedure as I am demonstrating. I hope this video
helps anyone out there that needs to tackle such a job and the video also
shows that it can all be done with simple tools which in turn will save you

HP DV3 Laptop No Video/ Blank Screen, and Motherboard Removal/ Repair
This laptop had a no video issue like all HP, and Compaq laptops exhibit.
In this laptop I'm going to show you how to repair this no "video issue",
and show you how to remove the motherboard on this HP DV3 series laptop.
This repair procedure can be done on all HP, and Compaq laptops that show
no video, or have a blank black screen. I reflowed the video chip using a
heat gun. I have done this repair sucessfully on other HP and Compaqs
laptops in the past. I have never seen an ATI video graphics card fail on a
HP or Compaq laptop before. The video cards that show this problem are
always the Nvidia video graphics cards. This laptop was repaired
sucessfully, and works perfect now!
