Part 25: Turbo Manifold Fabrication - My 76 Mazda RX-5 Cosmo Restoration
Episode 25 of my '76 Mazda RX-5 Cosmo restoration is another long one,
covering in its entirety the fabrication of the turbocharger manifold. Suddenly the engine bay
started to look a little cramped when I began to position the GT3076R, so
it took some plumbing to build the required manifold. Constructed out of
1.5" SCH40 304 stainless steel pipe, it was fully TIG welded with an argon
back purge. Yes, this is another long episode because I wanted to show the
manifold fabrication process in glorious detail so that this video would be
a useful resource for anyone wanting to build a custom turbo manifold. So as I say, grab your favourite
adult beverage, sit back, and enjoy. Included in this episode: fabricating
a 13B Exhaust flange, fabbing a merge
collector, positioning a turbo in the
engine bay, measuring, cutting and fitting stainless pipe and els, tacking
in position, setting up a back purge, final welding, port matching, custom
A huge thank you to ATP turbo (

customer brought in a Z24 just like mine! 3.1 5 speed... 3.1 was blowen,
sounds like a wrist pin let go. for the same price of replacing the old 3.1
with another old 3.1, he decided to bring it to me, the expert! and have a

Buick - 3100 SFI Engine Training (1994)
This video from GM's Certified-Plus Training series provides details of the

Topics covered include: 1996 Government Requirements, Engine Introduction,
Management Strategy, Diagnosis Review and Service.
How To Unsieze An Engine
This is the diesel I got for the Astro van, basically free, with the 700R4
transmission. Which ironically turned out to be a great transmission, the
only one of three that has a good fourth gear, but I rebuilt it anyway.
Who knew a 30 year old automatic could still be sweet inside.
I have unsiezed this diesel engine like this three times now. It
obviously has some internal problems. So its on the list to get a tear
down and rebuild, right after the Ranger is back together. It takes about
an hour or more to get this motor turning over 360 deg. Then it won't
quite fire, but makes little smoke puffs.
The starter in the 6.2 diesel has some serious torque, sucks the battery
voltage down and makes a tremendous amount of heat. It still takes an hour
of cranking an eighth of an inch at a time.
Fix It Right! - Intake Manifold Gasket Replacement
Fix It Right! - Intake Manifold Gasket Replacement (S1E4)
Demonstrated on a 2004 Buick Century 3.1L V6 FWD.
In this video, we demonstrate how to perform an intake manifold gasket
replacement on a front-wheel-drive 3.1L V6 engine, in this case in a 2004
Buick Century. This is a common point of failure on General Motors' 3.1L,
3.4L, and 3.8L V6 engines, which are used in a large number of passenger
cars across most of GM's model lines.

About the "Fix It Right!" video series:
"Fix It Right!" is a series of how-to videos intended to give
do-it-yourselfers basic instructions on proper vehicle repair and
maintenance. All of our videos show real repairs being performed on real
vehicles by real technicians in a real auto shop. (Repairs are filmed and
shown with the permission of the vehicles' owners.) Although there may be
more than one way to perform any particular repair (and in many cases there
are lots of ways!) we try to focus on the methods that will be safest and
most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex
or dangerous for DIY, or require specialized tooling, expertise, equipment,
and/or certifications. Those episodes will highlight the importance of
hiring a professional auto technician for tasks that are not DIY-friendly,
and demonstrate why such tasks are best left to professionals.

GM 3400 / 3100 3.1 3.4 Engine Misfire Cause & Causes Miss Missing P0303
Here is a video for fellow GM 3400 & 3100 liter engine owners. Have a
misfire? This video explains the causes for what could be causing the
problem. Mine showed up as a P0303 cylinder 3 misfire. Couldn't figure it
out, but finally did. The spark plug and wire were replaced along with a
new coil. Could hear the injector firing with a stethoscope but still had
the miss. Found out after tearing into the intake that the lower intake
If your car is missing out, first try the following. Check for spark and
check the spark plug, wire and coil. A test you can do if it randomly
misses is in the dark, spray a mist of water around the plug wires. If you
see blue arcing, you've found the problem. But be careful not to zap
yourself, IT HURTS!
If the spark is good the listen at the injector. Is it firing and
clicking? If not, you've found the problem.
If both those seem good, then check for compression. Do this with a
compression tester available at any Autozone with the loan a tool program
If all 3 of those check out then it's a possible vacuum leak. May be time
to do an intake manifold gasket repair as they are known to go out. But,
if you do have to do an intake manifold gasket fix, go ahead and replace
the head gaskets too. You'll be glad you did. Not fun taking it all back
apart again. Check out my youtube channel for these videos both on doing
the lower intake manifold gasket and the head gasket.

How to Break In A New or Rebuilt Engine - EricTheCarGuy
Visit me at
I'm sure there is more than one way to do this but this is the way that I
was taught and it seems to work as intended. The idea is to make sure the
engine is fully lubricated before you start it up for the first time as we
know all too well what happens to an engine without oil, in fact I forgot
to show me filling up the oil filter with oil before I installed it sorry.

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.
