As can be seen from the old intake manifold gasket, she was definitely leaking on 2 and 3
The gasket was hard and brittle, probably still the original from 87.
She also has a hard time starting when cold which usually everyone says is the FPR. I have ordered another FPR to replace the original one.
While the intake was off I thought I may as well pull the injectors and have them cleaned on my mates injector cleaner.
The initial spray test showed that 3 of the injectors were within 1mm of each other and 1 injector sprayed an extra 2mm. Also 2 of the injectors had a different spray pattern. 1 was shooting diagonally.
They were put into an ultra sonic bath and the crap started coming out pretty soon
You can see all the crap coming out of them. My mate usually outs injectors into a bath for 45 minutes. These were in for 3 hours.
The after test had all injectors spraying perfect and all were at the same amount.
I also found the idle bypass hose had exploded
The crack was several inches long. I have put another hose in there for the time being until I order the correct part from IPD.
I got it all together last night and she started first turn. No hesitation. I will still get the FPR to make sure the fuel side is all good.
Next will be a good engine bay degrease, not sure if I will remove the bonnet sound deadening, will have think on that one.
Test drive tomorrow as there is a cars & coffee near me So will see if she goes better...
