| Z Back and doing well...
Just thought I would post a few pics of what I've been up to for the last few
days.
The main bolt in
my timing belt tensioner failed after 8000 miles since a tb change at a
local Nissan dealership. I brought the car to them for "peace of mind"!!!
They actually installed 2 tbs as they dropped a washer from the water pump into
the first one.When I picked up the car the valve timing was at least a cog out.
I was there for the disassembly and the washer had punched a hole in the belt
so large you could put your little finger through it. They preceded to remove
the old belt without inserting the stop bolt into the tensioner assembly allowing
it fully extend. I didn't know at the time that the tensioner could not
be reset. On reassembly the belt was too tight...
A few weeks before the failure I did notice a slight whine from the tb but
dismissed it! The effect was 24 valves looking like "mushrooms". I
brought the car back to them but after 2 weeks they said they didn't have a
mechanic "QUALIFIED" to work on it. I got the car home and got busy
with the service manual. I had built a few american V8s in the past, but this
was fun!
Got the parts from z1motorsports
on Monday 20th. Must say thanks to Robert@Z1 for sorting out the parts. I drove
the car to work on Thursday. Its running better than ever! Lots learned!
This was a great opportunity to port the heads and manifolds. I also eliminated
the EGR, AIV, and Plenum heating system.
Heads off:
Replace EFI connectors
Lets make a valve seal drift:

Time for beer while topping up coolant:
Jesus, I must love this car!
