Feb 2002: 305 parting and coming out (cont'd):
) ) I
remove the water pump. I clean it and paint it silver.
I remove the pulleys. I also clean and paint them but I choose the orange color for them. |
) Bad
surprise : After removing the exhaust manifolds, I discover the passenger
side manifold has cast cancer. This should be the source of the leak noise
I had. This is anoing, because I didn't planed to upgrade it now. Someday,
I'll put headers but once I'm done with the engine.
I remove the starter. As it was repared one year ago, there is nothing to do on it. |
) ) Lucky
time now: when I remove the converter housing, I find these 2 bolts in
the bottom. They were on the converter. I figure out why the entire car
had vibrations sometimes. But when I notice the third and last bolt was
loose,I find how lucky I was to stop the car before getting stuck.
All the mounting brackets are also removed, cleaned and painted in black color with the converter housing |
) ) Once
I think that everything connected to the engine is disconnected , I attach
the hoist chains to the engine and raise it until all slack is out of the
chains.
With a little pull the engine leaves the torque converter. |
) )
I raise sloooowly the engine continually checking clearances around.
Clic-clic says the hoist, clic-clac answers the digital camera. |
) ) Even
you've checked everything, there is always something you forgot to disconnect:
for me, it was the ground wire on the passenger head.
Just after, the tranny vacuum line falls in love with the flywheel and doesn't want to leave it. |
) ) ) Now
I can raise fully the engine.
Here is how the tranny will stay hold without the engine. (Thank you for this smart trick, Mike) |
) ) ) The
engine is high in the sky (with diamond) and the mino is lowered. She can
be pushed backward. The engine is downloaded in the Sporty wheelbarrow. |
) Once
the 305 is out, I remove the engine mounts. I clean and paint them
black. I remove the flywheel and fix it to the new engine. These were the
last parts taken out of the old 305. |
) ) I
decide to use an exhaust paste which can stand 800°C to repare the
sick manifold. With a touch of HT silver paint, they look like (almost)
new. This allows me to go ahead with the engine.
I clean the ignition cables and take sometime to arrange them around the engine. |
) The
305 pinged on LPG, but never on Gas. The symptoms were like malfunctionning
EGR. Tests showed that the EGR was ineffective, so I decided to get rid
of it. I though the 305 heads had carbon deposits hotted by LPG burning
at higher temperature than Gas. But now I find that the pipe between the
EGR valve and the plenum was cloged. This explains why EGR couldn't be
effective. When ECM enables EGR, it advances ignition timing to balance
the EGR effect. Not enough to cause pinging on Gas, but enough for LPG.
LPG likes EGR because it lowers the combustion temperature. I have to fix
that . |
) ) ) I
scratch the deposits with this hard point. I have to push hard. Lot of
coal falls of the pipe. |
) )
I have to remove the plug made to block the intake heating to allow EGR
functionning.
I keep the other plug and will fill the heating pipe under the plenum with ???? (I dunno yet) I achieve to pass an old Tyrap (why not a Tyrap?) to check that the pipe is now wide open. I put the intake up side down on the vise to see more coal falling of. |
) ) ) Before
putting the new engine in the car, I check if all 305 accessories will
fit.
Good guess: I spent two hours on this oil sender plug. I had to drill it to remove it. NOT a easy job with the engine in the car... |
) ) I
go on with the 305 accessories checking: I put the water pump, the HEI,
the exhaust manifolds and the alternator after.
Pretty nice isn't it? Soon in the car... |
